Continue in the practice tool above to load more questions, 50 at a time.

Question 1Avamar deduplication, clients and recoverable backups

Which Avamar Web UI (AUI) capability allows administrators to filter and inspect recent backup, restore, replication, and validation activities?

  1. Activity Monitor Correct answer.
  2. DD Boost dashboard
  3. Magistrate inspector
  4. Cloud Tier wizard

Explanation

Activity Monitor is the relevant activity-inspection view in the supplied AUI model. Exact fields, available activity types, time filters and default list limits depend on version and configuration. Correlate the intended client, operation and result rather than assume a universal five-thousand-row view is complete evidence.

Question 2Avamar deduplication, clients and recoverable backups

In the AUI, which page lets an administrator define what files/objects are included or excluded from a backup?

  1. Schedule
  2. Dataset Correct answer.
  3. Retention policy
  4. Group

Explanation

Datasets specify the source-side selection rules (paths, exclusions, plug-in options) for what is backed up. They are applied to clients indirectly through groups.

Question 3Avamar deduplication, clients and recoverable backups

Which Avamar tool produces a system health and best-practice score covering capacity, performance, and policy hygiene?

  1. Avamar Fitness Analyzer Correct answer.
  2. Pearson VUE Score Report
  3. iDRAC Lifecycle Log
  4. DDOS DD Boost

Explanation

The Avamar Fitness Analyzer evaluates system health (capacity utilization, checkpoint state, schedule overruns, etc.) and produces actionable findings against Dell-published best practices, helping admins triage risk before failures.

Question 4Avamar deduplication, clients and recoverable backups

Which Avamar replication topology copies a single source server to a single destination server and never replicates back?

  1. One-way (source-to-destination) Correct answer.
  2. Bidirectional
  3. Cross-replication
  4. Many-to-one

Explanation

One-way replication copies backups from a source Avamar server to a destination Avamar server only. It is the simplest topology: the destination does not replicate any of its content back to the source.

Question 5Avamar deduplication, clients and recoverable backups

Which replication topology lets two Avamar servers replicate each other's content for mutual disaster recovery?

  1. One-way
  2. Cross-replication (each server replicates to the other) Correct answer.
  3. Local replication only
  4. Tape-based replication

Explanation

Cross-replication pairs two Avamar servers so each replicates the other's protected backups. It provides mutual DR coverage and is one of the standard supported Avamar topologies (along with one-way, many-to-one, one-to-many, and chain).

Question 6Avamar deduplication, clients and recoverable backups

Which Avamar replication mode is used in Avamar 7.0 and later, where replication is triggered by the MCS Scheduler workflow rather than by repl_cron and Linux crontab?

  1. Cron-based replication
  2. Plug-in based replication Correct answer.
  3. Tape replication
  4. iSCSI replication

Explanation

Plug-in based replication (Avamar 7.0+) replaces the older cron-based replication. The MCS Scheduler triggers a workflow that calls avrepl, which in turn calls avtar to replicate. It is the supported model in modern Avamar (including 19.x).

Question 7Avamar deduplication, clients and recoverable backups

Which command, executed on the utility node, manually runs an Avamar replication task?

  1. avtar
  2. avwarden
  3. avrepl Correct answer.
  4. ddboost

Explanation

avrepl is the Avamar replication binary. For policy-based replication the Scheduler invokes avrepl; for command-line replication, an admin can run avrepl directly on the utility node to start a one-off task.

Question 8Avamar deduplication, clients and recoverable backups

Which feature allows Avamar to use a Data Domain system as the backup target for higher-throughput / higher-density workloads such as databases and image-level VM backups?

  1. Avamar Tier with Data Domain (DD Boost integration) Correct answer.
  2. Cloud Tier to AWS Glacier
  3. Tape staging
  4. PowerScale OneFS dedup

Explanation

Avamar integrates with Data Domain through DD Boost. Plug-ins such as VMware Image, SQL, Exchange, and Oracle can stream backup data directly to a Data Domain system (for high throughput/scale) while the Avamar server tracks the catalog and policies.

Question 9Avamar deduplication, clients and recoverable backups

Which library is used by Avamar plug-ins to send deduplicated streams to a Data Domain system?

  1. DD Boost Correct answer.
  2. iSCSI
  3. RACADM
  4. NDMP DUMP

Explanation

DD Boost is the client-side library and protocol that performs distributed segment-level deduplication between an Avamar (or other backup) client and the Data Domain target, sending only unique segments over the wire.

Question 10Avamar deduplication, clients and recoverable backups

Which feature allows long-term retention by tiering older Avamar backups stored on a Data Domain system to object storage (for example, ECS or S3-compatible)?

  1. Avamar Cloud Tier (working with Data Domain Cloud Tier) Correct answer.
  2. Cross-replication
  3. vSphere Storage vMotion
  4. iDRAC Group Manager

Explanation

Avamar Cloud Tier works in tandem with Data Domain Cloud Tier to move older Avamar backups stored on Data Domain to a configured cloud object store (ECS, AWS S3, Azure Blob, etc.) for long-term retention. The Avamar AUI is used to define and run the data-movement policy.

Question 11Avamar deduplication, clients and recoverable backups

What MUST be configured on the Data Domain system BEFORE Avamar Cloud Tier can be enabled in the AUI?

  1. A pre-configured cloud storage unit on the Data Domain (with cloud profile and credentials) Correct answer.
  2. Microsoft Hyper-V replica
  3. An NDMP Accelerator on the same VLAN
  4. A spare PowerEdge with NVMe storage

Explanation

Avamar Cloud Tier requires that the Data Domain administrator first creates a cloud storage unit on the DD system with the cloud provider profile (ECS/S3/Azure) and credentials. The AUI then uses that unit when configuring the data-movement policy.

Question 12Avamar deduplication, clients and recoverable backups

Which Avamar plug-in performs image-level backup of vSphere virtual machines via VADP, using a transport proxy?

  1. vProxy (Avamar Plug-in for VMware Image-Level) Correct answer.
  2. Avamar Plug-in for SQL Server
  3. Avamar Plug-in for Exchange
  4. Avamar Plug-in for Oracle

Explanation

vProxy is Avamar's VMware image-level backup proxy. It uses VADP (vSphere APIs for Data Protection) to take VM snapshots and reads changed blocks via CBT, supporting backup and restore of VMs, including FLR without admin/root privileges and with Dynamic Disk awareness on Windows.

Question 13Avamar deduplication, clients and recoverable backups

Which vProxy safety check prevents an image-level backup from running when the VM's datastore lacks free space for a snapshot?

  1. Snapshot free-space threshold Correct answer.
  2. Magistrate offense correlation
  3. vCenter HA datastore heartbeat
  4. iDRAC fan threshold

Explanation

vProxy checks the snapshot free-space threshold on the datastore before initiating a VM snapshot. If the datastore would run out of room, the backup is skipped instead of risking VM stun or datastore exhaustion.

Question 14Avamar deduplication, clients and recoverable backups

Which Avamar plug-in is appropriate for protecting Microsoft SQL Server, including SQL Always-On Availability Groups?

  1. Avamar Plug-in for Microsoft SQL Server Correct answer.
  2. Avamar Plug-in for Exchange
  3. Avamar Plug-in for Linux File System
  4. vProxy

Explanation

The Microsoft SQL Server plug-in provides full, differential, and log backup/restore for SQL Server, including AAG (Always-On Availability Groups). On AAG secondaries, incremental backups can be promoted to full if SQL takes time to update LSN in msdb.

Question 15Avamar deduplication, clients and recoverable backups

Which Avamar plug-in protects on-premises Microsoft Exchange databases at the database/mailbox level?

  1. Avamar Plug-in for Exchange Correct answer.
  2. Avamar Plug-in for SQL
  3. Avamar Plug-in for Oracle
  4. NDMP Accelerator

Explanation

The Exchange plug-in performs application-aware, VSS-quiesced backup and restore of Exchange databases. It supports DAG-aware backup selection and granular mailbox/item recovery.

Question 16Avamar deduplication, clients and recoverable backups

Which client plug-in does Avamar use to back up an arbitrary directory tree on a Linux host?

  1. Avamar Plug-in for Linux File System Correct answer.
  2. vProxy
  3. Avamar Plug-in for Exchange
  4. DD Boost

Explanation

The Linux File System plug-in is used for direct file/folder backup of Linux clients. Like its Windows counterpart, it leverages avtar for variable-length chunking and source dedup.

Question 17Avamar deduplication, clients and recoverable backups

Avamar offers push-upgrade of client packages for which set of client operating systems?

  1. Windows only
  2. Mac, Solaris, Debian Linux, Ubuntu Linux, and NDMP Accelerator clients Correct answer.
  3. Only z/OS clients
  4. Avamar does not support push-upgrade for any client

Explanation

Avamar supports push-upgrade for clients including Mac, Solaris, Debian Linux, Ubuntu Linux, and NDMP Accelerator nodes - administrators schedule upgrades from the AUI without logging into each client.

Question 18Avamar deduplication, clients and recoverable backups

An administrator needs to recover a SINGLE file from a VM image-level backup taken by vProxy. Which feature does the admin use?

  1. File-Level Recovery (FLR) - without requiring administrator/root privileges, and supporting Windows Dynamic Disks Correct answer.
  2. Restoring the entire VM and manually copying the file
  3. Cloud Tier rehydration only
  4. DD Boost direct mount on the production host

Explanation

vProxy supports File-Level Recovery (FLR) from image-level backups. FLR can be performed without administrator/root privileges on the target VM and supports Dynamic Disks on Windows guests, simplifying single-file recoveries.

Question 19Avamar deduplication, clients and recoverable backups

Which AUI workflow is used to define the rules that drive image-level VMware backups?

  1. AUI Policy wizard (groups, datasets, schedules, retention) for the VMware Image-Level plug-in Correct answer.
  2. iDRAC Group Manager
  3. vSphere DRS rules
  4. PowerProtect Cyber Recovery vault wizard

Explanation

The AUI policy wizard ties together the VMware Image-Level plug-in, dataset (which VMs/inclusions/exclusions), schedule, and retention policy via groups. Admins use it to schedule image-level backups instead of editing config files directly.

Question 20Avamar deduplication, clients and recoverable backups

Which retention catalog feature lets administrators apply a STANDARD retention policy globally instead of recreating the same expiration rule on every group?

  1. Retention Policy Catalog (preconfigured retention policies that can be referenced by groups) Correct answer.
  2. Magistrate offenses
  3. DD Boost replication seed
  4. iDRAC Lockdown Mode

Explanation

The Retention Policy Catalog ships with preconfigured retention policies and lets admins create custom policies once and reference them across many groups. This avoids per-group drift and makes retention auditable.

Question 21Avamar deduplication, clients and recoverable backups

Which best practice addresses an Avamar client that frequently exceeds the 24-hour overtime limit during large initial backups?

  1. Configure plug-in based replication / overtime to allow the long-running client beyond 24 hours per Dell KB guidance Correct answer.
  2. Cancel and rerun the client every hour
  3. Convert the workload to NDMP only
  4. Move the client to a faster Wi-Fi link

Explanation

Dell publishes guidance for configuring plug-in based replication overtime so that a long-running client can run beyond the default 24-hour window. This is the supported way to handle very large initial seed backups instead of repeatedly killing and restarting them.

Question 22Avamar deduplication, clients and recoverable backups

Which Avamar component does the AUI ultimately talk to in order to retrieve client lists, policies, and activity records?

  1. The MCS (Management Console Server) and its Postgres database Correct answer.
  2. DD Boost on the Data Domain
  3. The vCenter Inventory Service
  4. The iDRAC virtual console only

Explanation

The AUI is a web front-end on top of the Management Console Server (MCS). Clients, groups, datasets, schedules, retention policies, activities, and replication state all live in MCS and its Postgres database; the AUI is just the modern web UI for those services.

Question 23Avamar deduplication, clients and recoverable backups

An admin wants to configure pool-based replication when using a Data Domain target with multiple Avamar replication sources. Which document covers the integration?

  1. Dell EMC Avamar and Data Domain System Integration Guide Correct answer.
  2. Pearson VUE Candidate Handbook
  3. Microsoft Exchange Datasheet
  4. iDRAC9 RACADM Reference

Explanation

Pool-based replication, Cloud Tier prerequisites, and DD Boost configuration with Avamar are documented in the Dell EMC Avamar and Data Domain System Integration Guide. It is the canonical reference for joint Avamar + DD deployments.

Question 24Avamar deduplication, clients and recoverable backups

Which Avamar capability allows an administrator to perform server rollback to a previously validated state if data corruption is detected?

  1. Restore from a validated checkpoint Correct answer.
  2. Re-run vProxy snapshot consolidation
  3. DD Boost Lockdown
  4. iDRAC BIOS Recovery

Explanation

If corruption is detected, Avamar can be rolled back to a previously validated checkpoint. Because HFSCheck validates checkpoints, the validated checkpoint represents a known-good state and is the documented rollback path.

Question 25Avamar deduplication, clients and recoverable backups

Which AUI feature displays the most-recent client activities (default 5,000), and supports filtering by Last 24 hours or Last 72 hours?

  1. Activity Monitor Correct answer.
  2. Cloud Tier wizard
  3. Replication policy editor
  4. DD Boost dashboard

Explanation

The AUI Activity Monitor shows up to 5,000 recent activities by default and supports time filters such as Last 24 hours and Last 72 hours. Admins use it to spot failing clients and replication jobs at a glance.

Question 26Avamar deduplication, clients and recoverable backups

An administrator wants to verify daily that backups, GC, HFSCheck, and checkpoints all completed successfully. Which best-practice routine does Dell recommend?

  1. Run a daily health check that confirms checkpoint creation, HFSCheck pass, GC completion, and capacity below the documented threshold Correct answer.
  2. Reboot the utility node every morning
  3. Disable replication every night
  4. Manually delete all activity logs

Explanation

Dell's operational best practices recommend a daily comprehensive health check covering checkpoint creation, HFSCheck validation, GC completion, capacity headroom, and any failed clients. Treat any of those failing as an actionable alert before the next backup window.

Question 27Avamar deduplication, clients and recoverable backups

An admin needs to compare actual backup behavior against Dell's published best practices. Which Avamar tool is purpose-built for this?

  1. Avamar Fitness Analyzer Correct answer.
  2. DD Boost benchmark
  3. iDRAC SupportAssist
  4. Magistrate

Explanation

The Avamar Fitness Analyzer scores the system against published best practices (capacity, checkpoint, schedule, replication health) and produces actionable findings. It is the canonical tool for proactive Avamar health management.

Question 28Avamar deduplication, clients and recoverable backups

An admin uses the AUI to add a new local Avamar user and assign privileges. Which administrative concept defines the privilege set?

  1. Role Correct answer.
  2. Plug-in
  3. Schedule
  4. Hash

Explanation

Avamar uses roles to assign privileges to user accounts. The role defines what areas of the AUI/CLI the user can read or modify, while domains scope where the role applies (which clients/policies).

Question 29Avamar deduplication, clients and recoverable backups

Which Avamar concept partitions clients/groups into administrative scopes that can be delegated to different teams?

  1. Domains Correct answer.
  2. Stripes
  3. Atomics
  4. Magistrates

Explanation

Avamar domains are administrative containers that scope where a user/role applies. They allow large environments to delegate administration of subsets of clients (for example, by business unit or geography) without giving global rights.

Question 30Avamar deduplication, clients and recoverable backups

When using Avamar with Data Domain as the backup target for image-level VM backups, where is the deduplication primarily performed during the BACKUP path?

  1. Twice on the Data Domain only
  2. Source-side via the Avamar/vProxy + DD Boost client (only unique segments are sent over the wire) Correct answer.
  3. Inside the Avamar GSAN regardless of target
  4. By the production storage array

Explanation

When backing up to a Data Domain via DD Boost, the Avamar/vProxy client computes segment fingerprints, asks the DD which fingerprints already exist, and only sends new segments. Deduplication still happens at the source - DD Boost just talks to a DD target instead of GSAN.

Question 31Avamar deduplication, clients and recoverable backups

Which AUI workflow is used to schedule Avamar replication on a per-source basis (instead of running avrepl manually)?

  1. Replication policy + replication schedule (policy-based replication) Correct answer.
  2. iDRAC Lifecycle controller schedule
  3. vSphere DRS rules
  4. Postgres pg_dump cron

Explanation

Policy-based replication uses a replication policy (what to replicate, where to send it) plus a replication schedule (when and how often). The MCS Scheduler then triggers avrepl/avtar on the schedule. This is the supported alternative to manual avrepl runs.

Question 32Avamar deduplication, clients and recoverable backups

Which Avamar topology is referred to as 'many-to-one'?

  1. Multiple Avamar source servers all replicate into a single, larger destination Avamar server (consolidated DR site) Correct answer.
  2. One source server replicates to many destinations
  3. Two servers cross-replicate each other
  4. Tape rotation among many sites

Explanation

Many-to-one consolidates the contents of multiple replication source Avamar servers into a single, larger destination - typically a central DR site. It is one of the standard Avamar replication patterns alongside one-way, one-to-many, chain, and cross-replication.

Question 33Avamar deduplication, clients and recoverable backups

When Cloud Tier is configured against ECS via Data Domain, which Avamar versions support browsing of cloud-tiered backups in the AUI?

  1. Avamar 18.x+ with DDOS 6.1.x+ Correct answer.
  2. Avamar 6.0 only
  3. Only the legacy Java console - never the AUI
  4. Browsing requires unloading data back to GSAN first

Explanation

Browsing of cloud-tiered backups in the AUI is supported with Avamar 18.x+ paired with DDOS 6.1.x+ when ECS is the cloud provider. Earlier combinations did not allow browsing of tiered backups directly.

Question 34Avamar deduplication, clients and recoverable backups

Which Avamar capability allows direct restore (GLR/FLR) of cloud-tiered backups from ECS with Data Domain?

  1. Avamar 18.1+ paired with DDOS 6.1+ and ECS as Cloud Provider Correct answer.
  2. Only Avamar 6.x with NFS gateway
  3. Direct restore of cloud-tiered backups is not supported
  4. Restoration requires a tape library

Explanation

Direct restore of cloud-tiered backups (GLR/FLR) requires Avamar 18.1 or later with DDOS 6.1 or later when ECS is configured as the cloud provider. This combination is documented in the Avamar / Data Domain Cloud Tier KB.

Question 35Avamar deduplication, clients and recoverable backups

An administrator notices that an SQL AAG secondary's incremental backup was promoted to a FULL backup unexpectedly. Which root cause is the most likely on Avamar?

  1. The SQL Server took time to update the LSN in msdb after the previous incremental on the secondary, causing Avamar to promote the next incremental to full Correct answer.
  2. The Avamar utility node ran out of fan power
  3. DD Boost was disabled for the cluster
  4. iDRAC Lockdown Mode was on

Explanation

On an SQL Always-On secondary, if SQL has not yet updated the LSN inside msdb after a previous incremental, the Avamar SQL plug-in cannot chain the next incremental and promotes the next backup to a full to keep the chain valid.

Question 36Avamar deduplication, clients and recoverable backups

Which AUI page shows historic backup, restore, replication, and validation events for a single client over the past three days?

  1. Activity Monitor with the Last 72 hours filter Correct answer.
  2. Cloud Tier wizard
  3. vSphere Storage tab
  4. iDRAC SEL Log

Explanation

Filtering Activity Monitor to Last 72 hours and then by client name reveals the recent activity history (backup, restore, replication, validation) for that client. It is the fastest way to triage a single client's recent issues.

Question 37Avamar deduplication, clients and recoverable backups

Which Avamar feature is intended to address LONG-TERM RETENTION (years/decades) cost-effectively?

  1. Avamar Cloud Tier (move older Avamar backups stored on DD to cloud object storage) Correct answer.
  2. Storing all backups on the GSAN forever
  3. Replicating to another GSAN at the same site
  4. Using vSphere snapshots

Explanation

Avamar Cloud Tier is the documented long-term retention feature: Avamar backups stored on Data Domain are tiered to cloud object storage (ECS, S3, Azure Blob) where storage cost per TB is much lower for cold data.

Question 38Avamar deduplication, clients and recoverable backups

Which Avamar AUI element provides a single-pane summary of grid health, capacity, recent backups, and active alerts?

  1. AUI Dashboard / Server Management overview Correct answer.
  2. iDRAC Lifecycle Log
  3. vCenter Tasks pane
  4. DD Boost trace log

Explanation

The AUI Dashboard / Server Management overview consolidates grid health, capacity, recent activity, and alerts into a single pane that admins use as their day-one landing page when triaging the Avamar environment.

Question 39Avamar deduplication, clients and recoverable backups

Which Avamar feature is used for rapid recovery of an entire VMware virtual machine to a new location/host with the original disks restored?

  1. vProxy image-level restore (full VM restore to original or alternate location) Correct answer.
  2. DD Boost OST
  3. iDRAC virtual media
  4. Cloud Tier rehydrate-only

Explanation

vProxy image-level restore can recover a full VM to its original location, an alternate location, or a different vCenter, restoring all disks. It is the standard pattern for VM-level recovery using image-level backups.

Question 40Avamar deduplication, clients and recoverable backups

Which Avamar plug-in/feature is BEST suited to back up an isolated NetApp NAS volume directly to a Data Domain via the Avamar policy framework?

  1. NDMP Accelerator (physical or virtual) configured to direct NDMP backup data to a Data Domain target Correct answer.
  2. vProxy
  3. Avamar Plug-in for Exchange
  4. BOSS-N1

Explanation

An NDMP Accelerator (physical Gen4S/Gen4T, or vNDMP virtual) is the supported way to back up NetApp/NAS NDMP sources from Avamar. Backup data can be directed to Data Domain via DD Boost for capacity-efficient, dedup-aware NAS protection.

Question 41Avamar deduplication, clients and recoverable backups

Which workflow does Dell publish for confirming an Avamar deployment is healthy at the operational level (capacity, schedule, replication, fitness)?

  1. Comprehensive daily/weekly health check using AUI dashboard plus Avamar Fitness Analyzer findings Correct answer.
  2. Quarterly full grid reformat
  3. Daily reboot of all storage nodes
  4. Manual deletion of activity logs each morning

Explanation

Dell publishes a comprehensive Avamar health check pattern that combines AUI dashboard inspection (capacity, checkpoints, GC, HFSCheck, failed clients) with periodic Fitness Analyzer scoring against best practices. This is what auditors and Dell support expect to see.

Question 42Avamar deduplication, clients and recoverable backups

Which statement best describes the relationship between Avamar's MCS scheduler and replication tasks?

  1. Plug-in based replication uses an MCS Scheduler workflow that calls avrepl, which calls avtar to move data; this replaced cron-based repl_cron in Avamar 7.0+ Correct answer.
  2. Replication is started by Linux at(1) jobs
  3. Replication is started by SNMP traps from clients
  4. Replication runs only in response to manual restarts

Explanation

In Avamar 7.0+ (including 19.4 / D-AV-DY-23), the MCS Scheduler runs the replication workflow, invokes avrepl, and avrepl drives avtar to move data. This replaced the older cron-based mode (repl_cron + Linux crontab) used in 6.1 and earlier.

Question 43Avamar deduplication, clients and recoverable backups

An administrator wants to confirm that a particular client's restore test ran correctly last night. Which AUI workflow is the FIRST step?

  1. Open Activity Monitor, filter by activity type Restore and the appropriate time window, and inspect the result for that client Correct answer.
  2. SSH to the client and read /var/log/messages
  3. Reboot the utility node and re-deploy
  4. Open iDRAC SEL and filter by client name

Explanation

Activity Monitor is the canonical AUI starting point. Filter by type Restore and a time window (Last 24 hours / Last 72 hours), find the client's row, and inspect the result and duration. From there, drill into logs only if needed.

Question 44Avamar deduplication, clients and recoverable backups

Which document family does Dell publish that is the authoritative reference for an admin running daily/weekly Avamar tasks (datasets, schedules, retention, AUI usage, replication, Cloud Tier, capacity)?

  1. Dell Avamar Administration Guide (per release, e.g., 19.4) Correct answer.
  2. Dell PowerEdge Owner's Manual
  3. Dell iDRAC RACADM Reference
  4. VMware vSphere Hardening Guide

Explanation

The Avamar Administration Guide (per release; for D-AV-DY-23 this is the 19.4 series, with later guides including 19.7/19.8/19.9/19.10 covering similar concepts) is the authoritative reference for AUI usage, datasets, schedules, retention policies, replication, Cloud Tier, and daily maintenance.

Question 45Avamar maintenance, validation and capacity evidence

An installer is racking a new Avamar Data Store. How much rack height does each Gen4T node consume?

  1. 1U
  2. 2U Correct answer.
  3. 4U
  4. 6U

Explanation

Each Gen4T utility and storage node occupies 2U of rack space. A typical 40U rack hosts the utility node, the storage nodes, and the back-end switches with room for an optional spare or NDMP Accelerator.

Question 46Avamar maintenance, validation and capacity evidence

Which ADS Gen4T storage-node usable capacity options exist for a single rack?

  1. 1.4 TB, 2.6 TB, 3.9 TB, 7.8 TB Correct answer.
  2. 10 TB, 20 TB, 40 TB
  3. 500 GB, 1 TB, 1.5 TB
  4. Always exactly 7.8 TB

Explanation

Gen4T storage nodes are offered in 1.4 TB, 2.6 TB, 3.9 TB, and 7.8 TB usable capacity options. All storage nodes in one grid must use the same capacity model.

Question 47Avamar maintenance, validation and capacity evidence

What is the maximum number of active storage nodes supported in a single Avamar multi-node grid?

  1. 8
  2. 12
  3. 16 Correct answer.
  4. 32

Explanation

An Avamar multi-node grid supports up to 16 active storage nodes plus 1 utility node, with an optional 17th node that serves as a spare for node replacement. Beyond 16 storage nodes a second grid is required.

Question 48Avamar maintenance, validation and capacity evidence

Why does Dell recommend including a SPARE storage node in a multi-node Avamar grid?

  1. To double total grid capacity
  2. To allow online node replacement without losing protection level if an active storage node fails Correct answer.
  3. To run a separate Cloud Tier service
  4. To act as a permanent NDMP Accelerator

Explanation

The optional spare storage node sits idle on the back-end network. If an active storage node fails, GSAN can rebuild or take over onto the spare without forcing the customer to wait for hardware replacement, preserving RAIN protection.

Question 49Avamar maintenance, validation and capacity evidence

Which switch role(s) are deployed in a typical Avamar Data Store rack for the back-end (internal) GSAN network?

  1. Two redundant top-of-rack Ethernet switches dedicated to the internal node network Correct answer.
  2. A single Fibre Channel director
  3. Wi-Fi access points
  4. InfiniBand QDR fabric

Explanation

Each Avamar multi-node rack ships with two redundant Ethernet top-of-rack switches dedicated to the internal back-end network used by GSAN inter-node traffic. The customer-facing/external network connects through a different uplink.

Question 50Avamar maintenance, validation and capacity evidence

When physically replacing a failed storage node in a Gen4T grid, what is the FIRST procedural step?

  1. Remove the node from the rack and re-cable everything
  2. Suspend backups, take a checkpoint, and put the failed node into a service state per the replacement workbook Correct answer.
  3. Delete all backups associated with that node
  4. Reformat the storage on the remaining nodes

Explanation

Node replacement is a controlled procedure: suspend or quiesce backups, take a checkpoint as a rollback point, mark the failed node out of service through the documented runbook, and then physically replace and re-add the hardware. Skipping the checkpoint step risks irrecoverable data states.
