Question 1PowerProtect DD Architecture and Hardware Components

A PowerProtect DD appliance uses an active-passive controller pair. Which statement describes how the standby node behaves while the active node is serving data?

  1. It continuously serves read requests to balance load across both nodes
  2. It powers down completely until an administrator manually boots it
  3. It monitors the active node and takes over its identity if a failover occurs Correct answer.
  4. It runs only the DD Management Center software for the pair

Explanation

In an active-passive HA pair the standby controller keeps its storage and network state synchronized so it can assume the active role, including the service IP addresses, when a failure is detected. It does not process client backup traffic while the peer is healthy.

Question 2PowerProtect DD Architecture and Hardware Components

Which PowerProtect DD component is responsible for writing data to and reading data from the internal disk shelves?

  1. The customer's Ethernet switch
  2. The DD Management Center
  3. The storage processor in the controller Correct answer.
  4. The backup application media server

Explanation

The controller's storage processor and its RAID stack own the internal disk shelves and present usable storage to the DD file system. External hosts and management tools reach data only through the controller's network interfaces.

Question 3PowerProtect DD Architecture and Hardware Components

Which PowerProtect DD model family is designed primarily for large enterprise data centers and scales through external disk shelves rather than a fixed internal capacity?

  1. DD Virtual Edition
  2. DD3300
  3. DD6900 and above with external expansion shelves Correct answer.
  4. DD6400

Explanation

The midrange and high-end DD appliances support external expansion shelves, letting capacity grow well beyond the internal drive count. Entry models and the virtual edition are bounded by their built-in or provisioned capacity.

Question 4PowerProtect DD Architecture and Hardware Components

What is the primary function of NVRAM in a PowerProtect DD appliance?

  1. To cache user authentication credentials
  2. To store the DDOS image for the standby controller
  3. To stage incoming writes so they survive a power loss before being destaged to disk Correct answer.
  4. To hold the replication encryption keys

Explanation

NVRAM buffers write requests and is protected by a battery so that acknowledged writes are not lost if power fails. On restart the controller replays the NVRAM contents to complete the writes to disk.

Question 5PowerProtect DD Architecture and Hardware Components

A customer wants deduplication to reduce the capacity needed for repeated full backups of the same database. Which DD capability makes this possible across successive backup streams?

  1. Client-side encryption of each backup
  2. Global compression applied only within a single file
  3. Inline variable-length deduplication performed as data arrives Correct answer.
  4. Post-process deduplication run once per week

Explanation

DD performs inline variable-length deduplication on ingest, so identical or shifted blocks from later full backups are detected and stored only once. This is what allows repeated fulls to consume far less capacity than their logical size.

Question 6PowerProtect DD Architecture and Hardware Components

Which statement correctly describes the role of the DDOS file system's cleaning operation?

  1. It re-encrypts stored data with a rotated key
  2. It defragments the disk shelves to improve sequential read throughput
  3. It rebuilds the RAID parity on replacement disks
  4. It reclaims space occupied by chunks that are no longer referenced by any file Correct answer.

Explanation

Cleaning walks the file system metadata and frees chunks that no longer have any references, returning that capacity to the free pool. It is a garbage-collection process, not a defragmentation or RAID operation.

Question 7PowerProtect DD Architecture and Hardware Components

Which PowerProtect DD interface is used to configure replication between two appliances?

  1. The serial console port
  2. The data movement interface used for backup traffic only
  3. A dedicated replication interface configured in DDOS Correct answer.
  4. The service port on the management module

Explanation

Replication traffic flows over interfaces configured for that purpose in DDOS, typically separate from the backup data path so replication does not compete with ingest. Administrators assign these interfaces during replication setup.

Question 8PowerProtect DD Architecture and Hardware Components

In a DD High Availability pair, what happens to the service IP address during a failover?

  1. It is released and must be re-entered on every backup client
  2. It is reassigned to the surviving node so clients reconnect without reconfiguration Correct answer.
  3. It remains bound to the failed node until it reboots
  4. It is replaced by the node's private management address

Explanation

The HA pair presents a floating service address that moves to the surviving controller during takeover, so backup clients keep using the same target. This preserves client configuration and minimizes disruption.

Question 9PowerProtect DD Architecture and Hardware Components

Which DD component provides a single view of capacity, replication status, and alerts across many appliances?

  1. DD Management Center Correct answer.
  2. The replication throttle
  3. DD System Manager on each appliance
  4. The DD Boost plug-in

Explanation

DD Management Center is the centralized console that aggregates monitoring, reporting, and alerting for multiple DD systems. Per-appliance DD System Manager covers only the local system.

Question 10PowerProtect DD Architecture and Hardware Components

A PowerProtect DD appliance reports that a disk in a RAID group has failed. Which statement describes the expected behavior of the storage subsystem?

  1. The appliance halts all ingest until an administrator replaces the disk
  2. The failed disk is automatically excluded and capacity is permanently reduced
  3. All data on the failed disk is lost and must be restored from backup
  4. The RAID group continues serving I/O using parity until the disk is replaced and rebuilt Correct answer.

Explanation

RAID protects against single disk failure by reconstructing missing data from parity, so I/O continues in a degraded state. Once a replacement disk is installed, the subsystem rebuilds the group to restore full redundancy.

Question 11PowerProtect DD Architecture and Hardware Components

Which statement best describes how DD Boost distributes deduplication work between the backup server and the appliance?

  1. The appliance deduplicates only after the backup job completes
  2. The backup server performs all deduplication and sends only compressed data
  3. The backup server sends only unique segments and lets the appliance deduplicate them Correct answer.
  4. Deduplication is disabled for DD Boost traffic

Explanation

The DD Boost client library on the backup server fingerprints segments and forwards only those the appliance has not already stored, reducing network traffic. The appliance remains the authority for chunk storage and deduplication metadata.

Question 12PowerProtect DD Architecture and Hardware Components

What is the purpose of the DD Extended Retention software option?

  1. It allows a DD system to retain older backups longer on lower-cost storage tiers Correct answer.
  2. It encrypts data at rest for compliance
  3. It increases the number of supported backup clients per appliance
  4. It extends replication bandwidth for long-distance links

Explanation

Extended Retention lets a DD system keep long-term backup copies on additional storage tiers, supporting longer retention windows without consuming primary tier capacity. It is a retention and tiering capability, not a networking or encryption feature.

Question 13PowerProtect DD Architecture and Hardware Components

Which PowerProtect DD capability allows a backup application to write data over Ethernet without mounting a CIFS or NFS share?

  1. DD Retention Lock
  2. DD Boost over IP Correct answer.
  3. DD Encryption
  4. DD Replicator

Explanation

DD Boost provides an optimized transport that backup applications use over IP to send data directly to the appliance. It avoids the overhead of general-purpose file-sharing protocols while enabling distributed deduplication.

Question 14PowerProtect DD Architecture and Hardware Components

A customer needs to prove that archived backups cannot be altered for a regulated retention period. Which DD feature addresses this requirement?

  1. DD Management Center
  2. DD Boost
  3. DD Replicator
  4. DD Retention Lock Correct answer.

Explanation

Retention Lock enforces immutability for a defined period so that stored files cannot be modified or deleted before the retention time expires. This supports compliance with regulations that require tamper-evident archives.

Question 15PowerProtect DD Architecture and Hardware Components

Which statement describes the difference between the DDOS management interface and the data interface?

  1. The management interface must be on the same subnet as the backup clients
  2. The management interface carries administrative traffic while the data interface carries backup and replication traffic Correct answer.
  3. Both carry backup traffic and are interchangeable
  4. The data interface is used only for the serial console

Explanation

DDOS separates administrative access from data movement so that management sessions are not disrupted by heavy backup load. The data interface handles client ingest and replication streams.

Question 16PowerProtect DD Architecture and Hardware Components

Which PowerProtect DD model is a software-only deployment that runs on customer-provided virtual infrastructure?

  1. DD6900
  2. DD6400
  3. DD Virtual Edition Correct answer.
  4. DD3300

Explanation

DD Virtual Edition is packaged as a virtual appliance and runs on supported hypervisors using customer-supplied compute and storage. The other listed models are physical appliances with fixed hardware.

Question 17PowerProtect DD Architecture and Hardware Components

How does a DD system use the metadata it stores alongside data chunks to accelerate deduplication?

  1. It logs every client connection for auditing
  2. It records the backup application version for each stream
  3. It keeps an index mapping fingerprints to chunk locations so duplicate segments are found quickly Correct answer.
  4. It stores a checksum of each file name to detect renamed files

Explanation

The fingerprint index lets the appliance look up whether an incoming segment already exists before writing it. This metadata-driven lookup is what makes inline deduplication fast enough for streaming ingest.

Question 18PowerProtect DD Architecture and Hardware Components

Which statement describes the behavior of DD Replicator when a replication link is interrupted?

  1. The source discards unsent data and the replica becomes inconsistent
  2. Replication automatically converts to a full copy of all data
  3. The destination takes over ingest for the source appliance
  4. The source retains changes and replication resumes from where it stopped when connectivity returns Correct answer.

Explanation

DD Replicator tracks replication state so that an interrupted transfer resumes rather than restarting from the beginning. The source keeps unsent changes until the link is restored.

Question 19PowerProtect DD Architecture and Hardware Components

Which component of a PowerProtect DD appliance holds the DDOS software image that the controller boots from?

  1. The external disk shelf
  2. The DD Management Center server
  3. The NVRAM battery-backed cache
  4. The dedicated boot device in the controller Correct answer.

Explanation

Each controller boots DDOS from its own dedicated boot device, independent of the data disks. This allows the system to start even when data storage is being serviced.

Question 20PowerProtect DD Architecture and Hardware Components

A customer plans to replicate between two sites and wants to limit replication bandwidth during business hours. Which DD capability should be configured?

  1. A second management interface
  2. A larger NVRAM allocation
  3. A replication throttle schedule Correct answer.
  4. Additional RAID parity

Explanation

DD Replicator supports bandwidth throttling that can be scheduled so replication uses less WAN capacity during peak hours. This controls link utilization without stopping replication entirely.

Question 21PowerProtect DD Architecture and Hardware Components

Which statement explains why DD systems use variable-length rather than fixed-length segments for deduplication?

  1. Variable-length segmentation keeps boundaries aligned after insertions so shifted data still deduplicates Correct answer.
  2. Variable-length segments are always smaller and therefore faster to write
  3. Fixed-length segments cannot be compressed
  4. Variable-length segments eliminate the need for a fingerprint index

Explanation

When data is inserted or shifted, fixed-length boundaries move and previously identical blocks no longer match. Variable-length segmentation anchors boundaries to content so shifted regions still produce matching fingerprints.

Question 22PowerProtect DD Architecture and Hardware Components

Which PowerProtect DD hardware component provides redundant power so the appliance continues operating if one supply fails?

  1. The RAID controller battery
  2. The management module
  3. Dual redundant power supplies Correct answer.
  4. The NVRAM battery

Explanation

Appliances ship with redundant power supplies so a single supply failure does not interrupt operation. Each supply can carry the load until the failed unit is replaced.

Question 23PowerProtect DD Architecture and Hardware Components

Which statement describes how DD Encryption protects data at rest on a PowerProtect DD appliance?

  1. It encrypts only the metadata index
  2. It encrypts replication traffic between sites
  3. It encrypts backup streams in flight between client and appliance
  4. It encrypts data on the internal disks using keys managed by the appliance Correct answer.

Explanation

DD Encryption protects stored data on the appliance's disks with keys managed through DDOS. In-flight protection is handled separately by transport encryption such as TLS or IPsec.

Question 24PowerProtect DD Architecture and Hardware Components

A customer is comparing a DD appliance's logical backup capacity with its physical capacity. Which factor explains why logical capacity can greatly exceed physical capacity?

  1. The appliance compresses the capacity report
  2. Deduplication and compression reduce the physical footprint of repeated data Correct answer.
  3. Logical capacity is a licensing artifact with no relation to stored data
  4. RAID parity adds usable capacity beyond the raw disks

Explanation

Because duplicate segments are stored once and remaining data is compressed, the logical amount of protected data can far exceed the physical disk space consumed. The ratio depends on the redundancy in the data set.

Question 25PowerProtect DD Architecture and Hardware Components

Which DDOS feature allows an administrator to create a point-in-time readable copy of a file system for restore without duplicating the data?

  1. A cleaning operation
  2. A snapshot of the file system Correct answer.
  3. A replication job
  4. A RAID rebuild

Explanation

DDOS snapshots capture the state of a file system at a point in time and can be mounted for restores while sharing underlying chunks. They provide fast recovery without a full data copy.

Question 26PowerProtect DD Architecture and Hardware Components

A PowerProtect DD appliance is being installed in a rack, and the engineer must cable the controller's management connection. Which statement correctly identifies the purpose of the management port on a DD system?

  1. It carries production backup and restore traffic between clients and the appliance.
  2. It connects the appliance to the disk shelves for data transfer.
  3. It is used only for replication traffic between two DD systems.
  4. It provides out-of-band administrative access to DDOS for configuration and monitoring. Correct answer.

Explanation

The management interface is a dedicated out-of-band path used for administrative access to DDOS, such as the CLI, DD System Manager, and monitoring tools. It is kept separate from data-path traffic so that management operations do not compete with backup and restore I/O.

Question 27PowerProtect DD Architecture and Hardware Components

An administrator needs to protect a DD system configuration so it can be restored after a controller replacement. Which built-in DDOS capability stores a copy of the system configuration that can be used for recovery?

  1. The configuration backup and restore feature in DDOS Correct answer.
  2. The replication snapshot schedule
  3. The DD Boost storage-unit export policy
  4. The SNMP trap destination list

Explanation

DDOS includes a configuration backup and restore capability that captures system settings so they can be reapplied after a controller replacement or reinstallation. This preserves settings such as network configuration and system parameters without requiring manual re-entry.

Question 28PowerProtect DD Architecture and Hardware Components

A customer is designing a multi-site environment and asks how a DD system's storage capacity is licensed and consumed when data is replicated to a remote appliance. Which statement best describes how DD capacity licensing applies to replicated data on the target system?

  1. Replicated data is automatically deleted after each replication cycle to avoid capacity charges.
  2. Replicated data consumes physical capacity on the target system and is counted against that system's licensed capacity. Correct answer.
  3. Replicated data is stored on the source system only and the target holds just metadata.
  4. Replicated data consumes no capacity on the target because it is stored only in memory.

Explanation

When data is replicated, the target DD system stores its own physical copy of the replicated data, so that data consumes capacity on the target and counts against the target's licensed capacity. Capacity planning for a replication target must therefore account for the data it will receive.

Question 29PowerProtect DD Architecture and Hardware Components

A DD engineer is reviewing the role of the NVRAM module in a PowerProtect DD appliance. Which statement correctly describes the function of NVRAM in the data path?

  1. It buffers incoming writes so they can be acknowledged quickly and safely committed to disk. Correct answer.
  2. It holds the DDOS license keys and product serial number.
  3. It provides the network address translation for replication traffic.
  4. It permanently stores the deduplicated data chunks written by backup clients.

Explanation

NVRAM acts as a write buffer that allows the appliance to acknowledge writes quickly while protecting the data until it is safely written to persistent storage. This improves write performance without risking data loss if power is interrupted.

Question 30PowerProtect DD Architecture and Hardware Components

A DD system is configured with two controllers in a high availability pair, and the administrator wants to understand how data remains accessible if one controller fails. Which statement best describes the design intent of DD High Availability with respect to data access?

  1. Only the management interface fails over; data-path access must be restored by the backup application.
  2. The surviving controller takes over the failed controller's storage and service so clients continue to access data with minimal interruption. Correct answer.
  3. The failed controller's data is unavailable until a replacement controller is installed and resynchronized.
  4. Each controller stores an independent copy of all data so clients must be repointed manually after a failure.

Explanation

In a DD High Availability pair, the surviving controller assumes responsibility for the failed controller's storage and service, so clients continue to reach data with minimal interruption. Failover is designed to keep the data path available rather than requiring manual reconfiguration.

Question 31Deployment Planning and Site Preparation

When planning a new PowerProtect DD deployment, which document should be completed with the customer before hardware arrives to confirm rack space, power circuits, and network drops?

  1. A performance baseline report
  2. A completed data migration plan
  3. A disaster recovery test record
  4. A signed site readiness checklist Correct answer.

Explanation

Site preparation planning requires validating physical and environmental prerequisites before installation. A site readiness checklist captures rack units, power receptacle types, cooling, and network port availability so that installation engineers arrive with confirmed conditions. The other artifacts are produced later in the lifecycle and do not gate delivery.

Question 32Deployment Planning and Site Preparation

A customer plans to deploy a PowerProtect DD appliance into a data center with single-phase 208 V power. What must the site planner verify about the power receptacles before installation?

  1. That they supply at least 30 A per receptacle regardless of model
  2. That they are wired to a generator-backed bus only
  3. That they are on the same phase as the network switches
  4. That they match the power cord connectors shipped with the ordered model Correct answer.

Explanation

Power cord and receptacle compatibility is a physical prerequisite that varies by model and by ordered power option. The site planner must confirm the receptacle type matches the cords shipped with the specific configuration. Amperage requirements, redundancy, and phase relationships are separate design considerations.

Question 33Deployment Planning and Site Preparation

Which environmental measurement is most important to record during site preparation for a dense PowerProtect DD rack installation?

  1. Acoustic noise level in the adjacent office
  2. Intake air temperature at the front of the rack Correct answer.
  3. Floor tile color in the hot aisle
  4. Ambient humidity in the loading dock

Explanation

Storage hardware is cooled by air drawn in at the front of the rack, so intake temperature at the rack face determines whether inlet temperature limits are satisfied. Dock humidity and office noise do not describe the operating envelope at the equipment. Documentation of intake temperature supports both acceptance and later thermal troubleshooting.

Question 34Deployment Planning and Site Preparation

During deployment planning, the customer states that backup traffic must be isolated from production application traffic. What design element should the architect specify?

  1. A dedicated backup data network with its own VLAN and addressing Correct answer.
  2. A routed path that shares the production VLAN but uses QoS
  3. A single flat network to simplify switch configuration
  4. A separate management network used for all backup data

Explanation

Isolating backup traffic requires a distinct data network, typically implemented as dedicated interfaces, VLANs, and subnets for backup clients and the protection storage. This prevents large ingest streams from competing with production application flows. Management networks carry administrative access and are not sized or secured for bulk data.

Question 35Deployment Planning and Site Preparation

A site plan shows 10 GbE connectivity between backup clients and the PowerProtect DD system across a routed campus. Which planning consideration most directly affects achievable throughput?

  1. The color coding convention used for patch cables
  2. The number of unused switch ports in the core
  3. The brand of optical transceivers in the access layer
  4. End-to-end round-trip latency and the resulting TCP window behavior Correct answer.

Explanation

Backup ingest over TCP is sensitive to bandwidth-delay product, so latency across a routed path limits per-flow throughput unless window scaling and multiple streams are used. Port counts, transceiver vendors, and labeling conventions do not change the protocol-level throughput ceiling. Capacity planning should therefore include latency measurement, not just link speed.

Question 36Deployment Planning and Site Preparation

Which factor should drive the choice between a single high-capacity PowerProtect DD appliance and a scale-out multi-node configuration during planning?

  1. The number of administrators who will log in to the system
  2. The version of the backup software used by the client
  3. Projected ingest rate growth and the need to expand capacity and throughput incrementally Correct answer.
  4. The physical height of the rack in the data center

Explanation

Scale-out architectures are chosen when planning forecasts show sustained ingest growth and a need to add nodes for both capacity and performance without disruptive replacement. A single appliance suits environments with stable, bounded requirements. Administrator counts, rack height, and client software version do not determine the architecture.

Question 37Deployment Planning and Site Preparation

A customer needs replication to a secondary site for disaster recovery. What must be confirmed at the target site during deployment planning?

  1. Identical rack layout and cable lengths at both sites
  2. Sufficient capacity, compatible software version, and adequate network bandwidth to the source Correct answer.
  3. A separate backup catalog server at the target for every source system
  4. That the target site uses the same physical switch models as the source

Explanation

Replication planning requires the target to hold the replicated data sets, run a compatible software release, and be reachable over links sized for the change rate and recovery point objective. Physical symmetry between sites is not required. Replication does not demand a duplicate catalog per source system.

Question 38Deployment Planning and Site Preparation

Which statement best describes the purpose of a pre-deployment network validation in a PowerProtect DD project?

  1. It authorizes the purchase order for the hardware
  2. It confirms addressing, routing, name resolution, and firewall openings before installation Correct answer.
  3. It replaces the need for a site readiness checklist
  4. It certifies the final performance of the production backup schedule

Explanation

Network validation proves that the planned addresses, routes, DNS entries, and required firewall ports are in place and reachable from the intended clients and management hosts. Catching these gaps early avoids installation delays. It does not measure production performance and does not substitute for physical site checks.

Question 39Deployment Planning and Site Preparation

A planner is documenting management access for a new PowerProtect DD system. Which practice aligns with secure deployment planning?

  1. Placing management interfaces on a restricted administrative VLAN with controlled access Correct answer.
  2. Exposing management interfaces directly to the internet for vendor support
  3. Using the same untagged VLAN as backup clients for simplicity
  4. Disabling all management access after initial configuration

Explanation

Management interfaces should be segmented onto an administrative network reachable only by authorized operators and support tooling. This limits the blast radius of credential compromise and satisfies common security control requirements. Internet exposure and flat client VLANs both increase risk.

Question 40Deployment Planning and Site Preparation

During sizing, a customer reports 60 TB of new backup data per week with a 30-day retention and a 4x expected deduplication ratio. What should the planner do first to size usable capacity?

  1. Add the client count to the weekly ingest figure
  2. Multiply weekly ingest by 52 to obtain a one-year capacity figure
  3. Apply the deduplication and compression assumptions to the protected data volume over the retention window Correct answer.
  4. Divide the weekly ingest by the retention period in days

Explanation

Usable capacity planning starts from the total protected data footprint over the retention period and then applies expected reduction ratios from deduplication and compression. Multiplying weekly ingest by 52 ignores retention. Dividing by retention days or adding client counts produces dimensionally meaningless numbers.

Question 41Deployment Planning and Site Preparation

Why should a deployment plan identify the time zone and NTP sources for a PowerProtect DD system before installation?

  1. Consistent time synchronization supports log correlation, replication, and certificate validation Correct answer.
  2. Clock settings select the RAID level used for the storage
  3. Time zone settings determine the usable capacity of the appliance
  4. NTP configuration controls the deduplication ratio achieved

Explanation

Accurate, synchronized time is required for meaningful log and audit correlation across systems, for replication coordination, and for certificate validity checks. Time settings have no relationship to capacity, deduplication effectiveness, or RAID configuration. Documenting NTP sources avoids later troubleshooting of authentication and audit anomalies.

Question 42Deployment Planning and Site Preparation

A customer requests that backup data be encrypted at rest on the PowerProtect DD system. What planning item must be addressed before enabling this capability?

  1. Defining how encryption keys will be generated, stored, and escrowed Correct answer.
  2. Increasing the number of backup administrators
  3. Confirming that all clients run the same operating system
  4. Reducing the retention period to under 30 days

Explanation

Data-at-rest encryption depends on a key management strategy, including key generation, secure storage, backup, and escrow so that data remains recoverable if a key is lost. Client OS uniformity and administrator counts are unrelated. Retention length is a policy choice, not an encryption prerequisite.

Question 43Deployment Planning and Site Preparation

Which consideration governs the choice of rack location for a PowerProtect DD appliance that will be cabled to a nearby backup media server?

  1. The color of the rack's side panels
  2. The proximity of the appliance to the building's main electrical panel
  3. The number of vacant parking spaces near the loading dock
  4. Cable distance limits for the selected interconnect and available airflow within the rack Correct answer.

Explanation

Placement must respect the maximum cable length for the chosen interconnect technology while preserving front-to-back airflow and hot and cold aisle alignment. Electrical panel proximity is not a standard placement criterion. Parking and cosmetic details have no technical bearing.

Question 44Deployment Planning and Site Preparation

A planning team must decide how backup clients will resolve the PowerProtect DD data interfaces. Which approach best supports resilience?

  1. Hard-code a single data IP address in every client configuration
  2. Use the management interface address for all backup traffic
  3. Rely on broadcast name resolution on the backup VLAN
  4. Configure multiple data interfaces with DNS entries that clients can resolve to available addresses Correct answer.

Explanation

Publishing resilient data interfaces through DNS lets clients reach an available address if one path fails and supports load distribution. Hard-coding a single address creates a single point of failure. Using management addresses for data mixes administrative and data planes, and broadcast resolution is not a reliable enterprise mechanism.

Question 45Deployment Planning and Site Preparation

When planning firewall rules for a PowerProtect DD deployment, which principle should guide the rule set?

  1. Permit all traffic between the backup and production subnets to avoid change requests
  2. Permit only the specific ports and source subnets required by the documented data flows Correct answer.
  3. Permit only ICMP between all subnets
  4. Permit all inbound traffic from the internet to simplify remote support

Explanation

Firewall planning should enumerate the required flows, such as management, replication, and client data access, and permit only those ports between the necessary source and destination subnets. Broad permits undermine segmentation, and internet-wide inbound access is unacceptable. ICMP alone cannot carry the required application traffic.

Question 46Deployment Planning and Site Preparation

A customer's data center has redundant A and B power feeds. How should a planner document the power connection for a dual-power-supply PowerProtect DD configuration?

  1. Connect both power supplies to the same feed to simplify cabling
  2. Connect both supplies through a single unswitched power strip on the A feed
  3. Connect each power supply to a different feed to preserve redundancy Correct answer.
  4. Connect one supply to the A feed and leave the other unconnected

Explanation

To realize the redundancy designed into the hardware, each power supply should draw from a separate power distribution path, typically the A and B feeds. Sharing one feed or one strip leaves the system vulnerable to a single upstream failure. Leaving a supply unconnected wastes the redundancy entirely.

Question 47Deployment Planning and Site Preparation

Which planning artifact should define the acceptance criteria that must be met before a newly installed PowerProtect DD system is handed to operations?

  1. A deployment acceptance test plan with measurable pass criteria Correct answer.
  2. A vendor price list for optional components
  3. A marketing brochure describing product features
  4. An organizational chart of the IT department

Explanation

An acceptance test plan lists the checks, such as management reachability, client connectivity, and successful test backups, with explicit pass criteria so that handover is objective. Feature brochures, price lists, and org charts do not define technical acceptance. Agreeing on these criteria during planning prevents disputes at handover.

Question 48Deployment Planning and Site Preparation

A planner is evaluating whether a proposed site can support a large PowerProtect DD deployment. Which combination of measurements best characterizes the site's readiness?

  1. Count of desktop printers and their toner inventory
  2. Number of conference rooms, badge readers, and elevators
  3. Square footage of the building lobby and the age of the roof
  4. Available rack units, per-rack power budget, cooling capacity, and network port availability Correct answer.

Explanation

Deployment feasibility hinges on rack space, deliverable power, heat removal capacity, and network connectivity at the target location. These four dimensions determine whether the hardware can be installed and operated within limits. Building amenities and office equipment inventories do not constrain storage deployment.

Question 49Deployment Planning and Site Preparation

During planning, the customer states that backups must continue if one PowerProtect DD data interface fails. What design feature should the architect confirm is available?

  1. A second management address on the same subnet
  2. Interface failover or aggregation across multiple data ports Correct answer.
  3. A dedicated console connection for each administrator
  4. A single high-speed data port with the largest available link

Explanation

Resilience at the network layer requires either failover of a data interface to a standby port or link aggregation across multiple ports so that a single port failure does not stop backup traffic. A single port is a single point of failure regardless of speed. Console access and additional management addresses do not protect the data path.

Question 50Deployment Planning and Site Preparation

A customer wants to add capacity to an existing scale-out PowerProtect DD environment without a disruptive outage. What should the deployment plan address?

  1. Replacing all existing nodes with larger models in a single maintenance window
  2. Migrating all data to tape before adding capacity
  3. Reinstalling the operating environment on every existing node
  4. Node compatibility with the existing release and the process for adding a node to the active system Correct answer.

Explanation

Non-disruptive expansion in a scale-out system depends on the new node running a compatible software release and on following the supported procedure for joining a node to the active system. Wholesale replacement, tape migration, and reinstalling existing nodes are disruptive alternatives that the requirement excludes.
