Question 1Nutanix Database Service (NDB) Architecture and Components

In Nutanix Database Service, which component is responsible for hosting the database engines and running the actual database instances registered to NDB?

  1. The Era agent on the client workstation
  2. The Prism Central instance only
  3. The NDB management server (NDB controller)
  4. The registered database server VMs or clusters Correct answer.

Explanation

NDB separates control plane from data plane. The management server orchestrates operations, while the registered database server VMs or clusters host the database engine binaries and the actual database instances. The agent runs on those database servers, not on client workstations.

Question 2Nutanix Database Service (NDB) Architecture and Components

Which NDB component runs on each registered database server and carries out tasks such as taking snapshots and applying clones on that host?

  1. The NDB agent (Era agent) Correct answer.
  2. Prism Element
  3. The database profile
  4. The NDB management server

Explanation

The NDB agent is installed on each registered database server and executes the operations the management server dispatches locally, including snapshot and clone work. This distributed execution is why the agent must be healthy for provisioning and protection to succeed.

Question 3Nutanix Database Service (NDB) Architecture and Components

A database administrator wants to register an existing PostgreSQL instance running on a Nutanix VM into NDB without reinstalling the database. What must be present on that VM before registration can succeed?

  1. A second network interface dedicated to NDB traffic
  2. A database profile applied to the VM at the hypervisor layer
  3. The NDB agent installed and reachable from the management server Correct answer.
  4. A Prism Central extension installed inside the guest OS

Explanation

Registering an existing database requires the NDB agent on the target VM so the management server can communicate with and operate the database. Without a healthy, reachable agent, registration and subsequent operations cannot be performed.

Question 4Nutanix Database Service (NDB) Architecture and Components

What is the primary role of a database profile in NDB?

  1. To authenticate users against the corporate directory
  2. To define the engine-specific configuration used when provisioning and managing databases Correct answer.
  3. To assign Nutanix cluster storage containers to databases
  4. To store the backup retention schedule for each database

Explanation

A database profile captures engine-specific settings such as version, parameters, and sizing defaults that NDB uses when provisioning and managing databases of that engine. It is a reusable configuration template rather than a schedule, storage mapping, or identity source.

Question 5Nutanix Database Service (NDB) Architecture and Components

Which NDB object is used to define how often snapshots are taken and how long they are retained for a group of databases?

  1. The network profile
  2. The SLA policy Correct answer.
  3. The clone policy
  4. The database profile

Explanation

An SLA policy in NDB defines the snapshot cadence and retention rules that protection schedules apply to databases. Profiles configure engine settings, while SLA policies govern data protection behavior.

Question 6Nutanix Database Service (NDB) Architecture and Components

An administrator needs a lightweight, space-efficient copy of a production Oracle database for a development team. Which NDB capability is designed for this?

  1. A Prism Element storage container replication
  2. A full database restore to a new server
  3. A manual export and import through the database client
  4. A database clone using storage-efficient snapshots Correct answer.

Explanation

NDB cloning uses snapshots to create space-efficient copies of a source database, which is the intended mechanism for dev/test provisioning. A full restore or export/import is heavier and not the snapshot-based clone workflow.

Question 7Nutanix Database Service (NDB) Architecture and Components

Which statement best describes the relationship between NDB and Prism Central?

  1. NDB replaces Prism Central for all cluster management tasks
  2. NDB requires Prism Central for authentication of database users
  3. NDB runs only when Prism Element is absent
  4. NDB is deployed and managed through Prism Central and uses it for cluster-level integration Correct answer.

Explanation

NDB is deployed as a service managed through Prism Central and integrates with it for cluster awareness and infrastructure operations. It complements rather than replaces Prism Central, and it does not authenticate database users through it.

Question 8Nutanix Database Service (NDB) Architecture and Components

What does the NDB management server use to communicate with the database servers it manages?

  1. Direct SCSI commands to the storage layer
  2. A shared database link between the management server and each database
  3. The NDB agent channel over the management network Correct answer.
  4. SNMP traps from the hypervisor

Explanation

The management server communicates with each registered database server through the NDB agent over the network, dispatching operations and collecting status. It does not manage guests through storage-layer commands, database links, or SNMP.

Question 9Nutanix Database Service (NDB) Architecture and Components

Which NDB concept groups databases so that protection and administrative operations can be applied consistently across them?

  1. A database group or tag-based grouping Correct answer.
  2. A storage container
  3. A VLAN
  4. A Nutanix guest tool

Explanation

NDB allows databases to be grouped, for example through tags, so that SLA policies and operations can be applied consistently to a set of databases. Storage containers, VLANs, and guest tools are infrastructure constructs, not NDB database grouping mechanisms.

Question 10Nutanix Database Service (NDB) Architecture and Components

What is the purpose of registering a Nutanix cluster with NDB?

  1. To convert the cluster into a Prism Central instance
  2. To enable deduplication on the cluster storage
  3. To install the database engine binaries on the CVMs
  4. To allow NDB to provision and manage database server VMs on that cluster Correct answer.

Explanation

Registering a Nutanix cluster gives NDB the target infrastructure on which it can place and manage database server VMs. It does not change the cluster's role, enable storage features, or install engines on the controller VMs.

Question 11Nutanix Database Service (NDB) Architecture and Components

A protection schedule references an SLA policy that retains daily snapshots for seven days. What does NDB do with snapshots older than seven days for databases using that policy?

  1. It converts them into full backups automatically
  2. It expires them according to the retention rule Correct answer.
  3. It replicates them to Prism Central storage
  4. It retains them indefinitely until manually deleted

Explanation

Retention rules in the SLA policy determine how long snapshots are kept; snapshots beyond the configured retention are expired automatically. NDB does not silently convert snapshots to full backups, keep them forever, or move them into Prism Central storage.

Question 12Nutanix Database Service (NDB) Architecture and Components

Which two pieces together form the core split of the NDB architecture?

  1. The Prism Element and Prism Central layers
  2. The database profile and the SLA policy
  3. The storage container and the volume group
  4. The control plane on the management server and the data plane on database servers Correct answer.

Explanation

NDB is organized as a control plane, the management server that orchestrates operations, and a data plane, the registered database servers that host the engines and data. This separation lets NDB manage many databases centrally while work executes locally through agents.

Question 13Nutanix Database Service (NDB) Architecture and Components

An administrator wants NDB to send alerts about failed database operations to an external monitoring system. Which NDB capability supports this?

  1. Editing the database profile to include an alert parameter
  2. Configuring alert and notification settings with an SMTP or webhook destination Correct answer.
  3. Enabling deduplication on the storage container
  4. Installing Prism Central on each database server

Explanation

NDB provides alert and notification configuration so operational events can be delivered to external destinations such as email or integrated endpoints. Database profiles, Prism Central placement, and storage deduplication do not deliver NDB operation alerts.

Question 14Nutanix Database Service (NDB) Architecture and Components

Which statement accurately describes how NDB handles database engine versions across different engines such as PostgreSQL, MySQL, and Oracle?

  1. NDB supports only a single engine per management server
  2. NDB supports multiple engines and versions through engine-specific profiles Correct answer.
  3. Engine versions are fixed by the Nutanix AOS release
  4. All engines must run the same major version to be managed by NDB

Explanation

NDB is multi-engine and uses engine-specific profiles to capture supported versions and configuration for each engine. A single management server can manage multiple engines and versions, and AOS releases do not dictate database engine versions.

Question 15Nutanix Database Service (NDB) Architecture and Components

What does the NDB management server require in order to be deployed in a Nutanix environment?

  1. A dedicated Oracle Exadata appliance
  2. A standalone physical server outside the Nutanix environment
  3. A direct fibre channel connection to each database server
  4. A registered Nutanix cluster and Prism Central to host and manage the NDB VM Correct answer.

Explanation

NDB is deployed as a VM on a registered Nutanix cluster and is managed through Prism Central, which provides the underlying infrastructure integration. It does not require external physical hardware, direct fibre channel links to guests, or vendor appliances.

Question 16Nutanix Database Service (NDB) Architecture and Components

A database administrator deletes a clone that was created from a production snapshot. What is the expected effect on the source database?

  1. The source database is also deleted because clones share the snapshot
  2. The source database loses its protection schedule
  3. The source database is rolled back to the snapshot state
  4. The source database remains intact because the clone is an independent copy Correct answer.

Explanation

A clone is an independent database derived from a snapshot, so removing the clone does not affect the source database or its protection configuration. The snapshot relationship enables efficiency but does not make deletion cascade to the source.

Question 17Nutanix Database Service (NDB) Architecture and Components

Which NDB feature allows a database to be restored to a specific point in time using captured snapshots and logs?

  1. Storage container replication
  2. Point-in-time recovery Correct answer.
  3. Database profile versioning
  4. Prism Central category tagging

Explanation

Point-in-time recovery uses snapshots together with database logs to restore a database to a chosen moment. The other options relate to storage replication, configuration versioning, and infrastructure tagging, none of which provide PITR.

Question 18Nutanix Database Service (NDB) Architecture and Components

An administrator observes that provisioning a new database fails while the target VM is reachable over the network. Which NDB component should be checked first for health?

  1. The database profile retention setting
  2. The corporate DNS forwarder
  3. The Prism Element CVM on an unrelated cluster
  4. The NDB agent on the target database server Correct answer.

Explanation

Provisioning depends on the NDB agent on the target server to execute local steps; a reachable VM with an unhealthy or stopped agent will still fail. Checking agent health is the first diagnostic step before investigating unrelated infrastructure.

Question 19Nutanix Database Service (NDB) Architecture and Components

Which statement best explains why NDB uses snapshots rather than full copies when creating clones?

  1. Snapshots enable space-efficient, fast copies that share unchanged blocks Correct answer.
  2. Snapshots eliminate the need for the NDB agent
  3. Snapshots convert the clone into a read-only database
  4. Snapshots avoid the need for any database configuration

Explanation

Snapshot-based cloning shares unchanged storage blocks, so clones are created quickly and consume little additional space until data diverges. Snapshots do not remove configuration needs, eliminate the agent, or force read-only clones.

Question 20Nutanix Database Service (NDB) Architecture and Components

What is the function of a network profile in NDB?

  1. To define IP address and network settings used when provisioning database servers Correct answer.
  2. To set the NDB administrator password policy
  3. To configure snapshot retention intervals
  4. To select the database engine version

Explanation

A network profile supplies the network configuration, such as IP ranges and related settings, that NDB uses when provisioning database server VMs. Retention, engine version, and password policy are governed by other NDB objects.

Question 21Nutanix Database Service (NDB) Architecture and Components

Which NDB capability lets an administrator apply the same configuration baseline to many newly provisioned databases of the same engine?

  1. Creating a separate management server per database
  2. Assigning each database a unique VLAN
  3. Attaching a database profile during provisioning Correct answer.
  4. Disabling the NDB agent on each server

Explanation

Database profiles are reusable templates that carry engine-specific configuration, so attaching one during provisioning applies a consistent baseline. Per-database VLANs, extra management servers, and disabling agents do not achieve configuration consistency.

Question 22Nutanix Database Service (NDB) Architecture and Components

Which component must be operational for NDB to manage databases across multiple Nutanix clusters?

  1. A separate NDB management server installed on every database server
  2. A single Prism Central instance managing the registered clusters Correct answer.
  3. A dedicated physical switch per cluster
  4. An Oracle Grid Infrastructure installation on each cluster

Explanation

NDB integrates with Prism Central, which can manage multiple registered Nutanix clusters, enabling NDB to operate across them. It does not require an NDB server on every database server, dedicated switches, or engine-specific grid infrastructure for multi-cluster management.

Question 23Nutanix Database Service (NDB) Architecture and Components

What happens when a database is registered with NDB but no SLA policy is applied to it?

  1. It is deleted from NDB after 24 hours
  2. It has no NDB-managed snapshot protection until a policy is applied Correct answer.
  3. It is automatically protected with a default daily policy
  4. It is converted to a clone

Explanation

Protection in NDB is driven by SLA policies applied to databases; without one, NDB does not take scheduled snapshots for that database. Registration alone does not create default protection, deletion, or cloning.

Question 24Nutanix Database Service (NDB) Architecture and Components

Which NDB object stores credentials used to connect to a database for management operations?

  1. The storage container
  2. The Prism Central category
  3. The network profile
  4. The database registration's credential entry Correct answer.

Explanation

When a database is registered, NDB stores the credentials it needs to connect and perform management operations. Network profiles, categories, and storage containers do not hold database credentials.

Question 25Nutanix Database Service (NDB) Architecture and Components

An administrator wants to validate that a newly registered database is fully managed by NDB. Which observation best confirms successful management?

  1. The storage container shows increased deduplication
  2. The database appears in NDB with a healthy status and can be snapshotted through NDB Correct answer.
  3. The database VM appears in Prism Element inventory only
  4. The database engine logs show a restart

Explanation

Successful registration is confirmed when NDB lists the database with a healthy status and can perform operations such as snapshots through its own workflows. Mere presence in Prism Element, an engine restart, or storage deduplication does not demonstrate NDB management.

Question 26Nutanix Database Service (NDB) Architecture and Components

An administrator is planning the NDB deployment and wants to understand which layer is responsible for executing engine-specific operations such as taking a snapshot of a PostgreSQL instance or applying a patch to a SQL Server instance. Which NDB component performs these tasks?

  1. The Era management server service that brokers API requests
  2. The Nutanix cluster's Controller VM that owns the storage layer
  3. The Prism Central instance that hosts the NDB UI extension
  4. The database server agent running on the managed database VM Correct answer.

Explanation

NDB splits responsibilities between a central management server and agents installed on each managed database server. The agent on the database VM performs engine-specific local work such as snapshot orchestration, patching, and log capture, and reports results back to the management server. Prism Central and the Controller VMs provide UI and storage functions but do not execute database engine operations.

Question 27Nutanix Database Service (NDB) Architecture and Components

An administrator wants to deploy the NDB management server as a VM on an existing Nutanix cluster. Which prerequisite is specific to this deployment model?

  1. The target cluster must be registered with a Prism Central instance and have enough resources for the NDB VM Correct answer.
  2. A separate physical bastion host must provide the NDB database engine binaries
  3. The cluster must be licensed for a third-party backup product before NDB can be installed
  4. The NDB VM must run on a hypervisor other than AHV to isolate management traffic

Explanation

When NDB is deployed on a Nutanix cluster, that cluster must be managed through Prism Central, and the NDB VM needs adequate CPU, memory, and storage. NDB is a Nutanix-native service, so it runs on AHV and does not require an external hypervisor or third-party backup license.

Question 28Nutanix Database Service (NDB) Architecture and Components

A database administrator needs to take an existing production PostgreSQL database that was not created by NDB and bring it under NDB management so that clones and snapshots can be created from it. Which action accomplishes this?

  1. Provision a new NDB-managed database and manually copy the data files into it
  2. Register the existing database with NDB and associate it with a time machine Correct answer.
  3. Create an SLA policy and apply it directly to the database's data files
  4. Attach the database's storage container to the NDB management server VM

Explanation

Registration is the mechanism for bringing an already-running database under NDB control without recreating it. Once registered, the database is associated with a time machine that captures snapshots and logs, enabling clones and point-in-time operations. Copying data files or attaching storage does not create the management relationship.

Question 29Nutanix Database Service (NDB) Architecture and Components

An administrator deletes a clone that was created from a production database snapshot. What happens to the production database and its snapshots?

  1. The source snapshots are deleted along with the clone to reclaim space
  2. The production database is removed because the clone shares its storage with the source
  3. The production database and its snapshots remain intact because the clone is an independent copy Correct answer.
  4. The production database is rolled back to the snapshot used to create the clone

Explanation

A clone is an independent database instance derived from a snapshot, so deleting it affects only that clone. The source database and the snapshots held in its time machine are unaffected, and no rollback of production occurs.

Question 30Nutanix Database Service (NDB) Architecture and Components

An administrator wants to understand how NDB achieves near-instant clone creation for large databases. Which statement best explains the underlying mechanism?

  1. Clones reference snapshot data through efficient copy mechanisms, so only changed blocks consume additional space Correct answer.
  2. Clones require the source database to be shut down so files can be copied block by block
  3. Clones are created by running a full logical export and import of every table into a new database
  4. Clones are thin-provisioned VMs that stream data from the source database at first query time

Explanation

NDB leverages Nutanix snapshot and clone technology so a new database can be created quickly from a point-in-time snapshot. The clone references existing snapshot data and only diverging blocks consume extra storage, avoiding a full physical copy. This is why clone creation is fast even for large databases.

Question 31Deployment, Installation, and Initial Configuration

When deploying Prism Central for a Nutanix Database Service (NDB) environment, which deployment method does Nutanix recommend for a production-scale management plane?

  1. Deploying a multi-node Prism Central cluster with an odd number of VMs Correct answer.
  2. Deploying a single-node Prism Central VM using the one-click installer
  3. Installing Prism Central as an agent inside each database VM
  4. Running Prism Central in a container on the CVM

Explanation

Nutanix recommends a multi-node Prism Central cluster (typically three VMs) for production, providing resilience and scale for the management plane that NDB depends on. A single-node deployment is acceptable only for small or proof-of-concept environments. Prism Central runs as dedicated VMs, not as an agent inside database VMs or as a CVM container.

Question 32Deployment, Installation, and Initial Configuration

Which component must be registered with Prism Central before Nutanix Database Service can provision database instances?

  1. The NDB server VM Correct answer.
  2. The Nutanix Files server
  3. The Flow Virtual Networking gateway
  4. The Objects storage cluster

Explanation

The NDB server VM is the management component that Prism Central communicates with to orchestrate database provisioning. It must be deployed and registered with Prism Central before any database instances can be created. Files, Flow, and Objects are separate Nutanix services unrelated to NDB provisioning.

Question 33Deployment, Installation, and Initial Configuration

An administrator is preparing a Nutanix cluster to host NDB-managed database VMs. Which prerequisite must be satisfied on the cluster?

  1. The cluster must be licensed and registered with Prism Central Correct answer.
  2. The cluster must run only AHV with no ESXi hosts
  3. The cluster must have Objects storage enabled
  4. The cluster must have at least five nodes

Explanation

NDB manages clusters through Prism Central, so the target cluster must be licensed and registered to a Prism Central instance. Node count and hypervisor choice are not fixed prerequisites at that level, and Objects storage is unrelated to hosting database VMs.

Question 34Deployment, Installation, and Initial Configuration

Which network configuration is required so that the NDB server VM can manage database VMs across registered clusters?

  1. A dedicated VLAN with no routing to Prism Central
  2. Direct-attached crossover links between the NDB server and each CVM
  3. A shared iSCSI subnet between the NDB server and all database VMs
  4. IP connectivity and required ports open between the NDB server and the managed clusters Correct answer.

Explanation

The NDB server must have IP reachability to Prism Central and to the managed clusters, with the required management ports open. Without this connectivity, provisioning and lifecycle operations fail. iSCSI subnets and crossover links are storage or point-to-point constructs, not the management path.

Question 35Deployment, Installation, and Initial Configuration

During NDB deployment, which account credentials are typically supplied so that the NDB server can register with Prism Central?

  1. A Nutanix Support portal login
  2. A Prism Central admin account with sufficient privileges Correct answer.
  3. A guest OS account on each database VM
  4. A local CVM root account on every node

Explanation

The NDB server registers with Prism Central using a Prism Central administrative account that has the privileges needed to manage clusters and VMs. Guest OS and CVM root accounts are not used for this registration step, and a support portal login is unrelated to on-premises registration.

Question 36Deployment, Installation, and Initial Configuration

An administrator wants NDB to place database VMs on a specific subset of hosts within a registered cluster. Which NDB construct should be configured?

  1. A network profile
  2. A storage container
  3. A database server group Correct answer.
  4. A protection domain

Explanation

Database server groups in NDB define the compute resources (hosts) on which database VMs are placed, allowing administrators to target specific hardware. Protection domains and storage containers are storage-side constructs, and network profiles define IP ranges rather than host placement.

Question 37Deployment, Installation, and Initial Configuration

Which NDB construct defines the IP address range, gateway, and VLAN that database VMs will use when provisioned?

  1. A SLA policy
  2. A network profile Correct answer.
  3. A software profile
  4. A database parameter profile

Explanation

A network profile in NDB defines the IP pool, gateway, subnet mask, and VLAN used to assign addresses to provisioned database VMs. Parameter profiles and software profiles control database configuration and engine versions, while SLA policies govern protection.

Question 38Deployment, Installation, and Initial Configuration

Which profile type in NDB determines the database engine version and patch level applied to a newly provisioned instance?

  1. A compute profile
  2. A network profile
  3. A compliance policy
  4. A software profile Correct answer.

Explanation

A software profile in NDB bundles the database engine version and associated patches that will be installed on a new instance. Network profiles handle addressing, compute profiles handle VM sizing, and compliance policies handle governance.

Question 39Deployment, Installation, and Initial Configuration

An administrator must provision a database VM with a specific vCPU and memory footprint. Which NDB profile should be selected during provisioning?

  1. A software profile
  2. A database parameter profile
  3. A compute profile Correct answer.
  4. A network profile

Explanation

Compute profiles in NDB define the vCPU and memory sizing applied to the database VM at provisioning time. Software profiles control engine version, network profiles control addressing, and parameter profiles control engine settings.

Question 40Deployment, Installation, and Initial Configuration

Which NDB capability allows an administrator to define reusable engine-specific settings, such as memory allocation parameters, that are applied at provisioning?

  1. A protection domain
  2. A storage container
  3. A network profile
  4. A database parameter profile Correct answer.

Explanation

Database parameter profiles in NDB store engine-specific configuration parameters that can be applied consistently to new or existing instances. Network profiles, storage containers, and protection domains do not hold engine configuration parameters.

Question 41Deployment, Installation, and Initial Configuration

Before NDB can provision a database instance, which two items must exist as registered entities in the NDB inventory? (Choose the best single answer.)

  1. A registered Flow gateway and a protection domain
  2. A registered Prism Element and a Files share
  3. A registered cluster and an Objects bucket
  4. A registered cluster and a registered NDB server Correct answer.

Explanation

NDB provisioning requires a registered NDB server (the management component) and at least one registered cluster where the database VM will be placed. Objects buckets, Files shares, Flow gateways, and protection domains are not prerequisites for basic provisioning.

Question 42Deployment, Installation, and Initial Configuration

An administrator needs to ensure that NDB can reach a new cluster that is registered to the same Prism Central. What is the correct first step?

  1. Deploy a second Prism Central for that cluster
  2. Create a protection domain on the cluster
  3. Enable Objects on the cluster
  4. Register the cluster in NDB and verify connectivity to the NDB server Correct answer.

Explanation

After a cluster is registered with Prism Central, it must be registered in NDB, which verifies management connectivity from the NDB server. Protection domains, Objects, and additional Prism Central instances are not required for this step.

Question 43Deployment, Installation, and Initial Configuration

Which statement best describes the role of Prism Central in an NDB deployment?

  1. It provides the central management plane through which NDB manages clusters and VMs Correct answer.
  2. It replaces the CVM on each node
  3. It stores database backups in S3 buckets
  4. It runs the database engine for all instances

Explanation

Prism Central is the centralized management plane that NDB uses to interact with registered clusters and their VMs. It does not store backups, replace CVMs, or run database engines; those functions belong to other components.

Question 44Deployment, Installation, and Initial Configuration

An administrator is deploying the NDB server VM. Which sizing consideration is most relevant to support a large number of managed database instances?

  1. The number of NICs on each database VM
  2. The number of protection domains on the cluster
  3. The number of vCPUs and memory allocated to the NDB server VM Correct answer.
  4. The size of the Objects bucket

Explanation

The NDB server VM's vCPU and memory determine its capacity to orchestrate and monitor managed instances, so sizing should account for the expected scale. Database VM NIC count, Objects bucket size, and protection domain count do not size the management server.

Question 45Deployment, Installation, and Initial Configuration

Which NDB feature allows an administrator to apply a consistent set of configuration and protection settings to newly provisioned databases without repeating manual steps?

  1. Clone-based provisioning
  2. Ad-hoc provisioning
  3. Profile-driven provisioning Correct answer.
  4. Manual post-provision scripting

Explanation

Profile-driven provisioning uses predefined profiles (compute, network, software, parameter) and policies to standardize new database deployments. Ad-hoc and manual scripting approaches lack the reusable consistency that profiles provide, and cloning reproduces an existing instance rather than applying a defined profile set.

Question 46Deployment, Installation, and Initial Configuration

What is the purpose of registering a Prism Element cluster with NDB rather than only with Prism Central?

  1. It converts the cluster to ESXi
  2. It allows NDB to target that cluster's hosts and storage for database VM placement Correct answer.
  3. It removes the need for an NDB server
  4. It enables Objects storage on the cluster

Explanation

Registering a cluster in NDB makes its compute and storage resources available as a placement target for database VMs. It does not enable Objects, eliminate the NDB server, or change the hypervisor.

Question 47Deployment, Installation, and Initial Configuration

An administrator wants database VMs to receive addresses from a defined pool managed by NDB. Which configuration must be in place?

  1. An IP address management plugin in Prism Central
  2. A static route on the NDB server only
  3. A DHCP relay on every host
  4. A network profile containing the IP pool and gateway Correct answer.

Explanation

NDB assigns addresses to database VMs from the IP pool defined in a network profile, along with the gateway and VLAN. DHCP relays, NDB-server static routes, and external IPAM plugins are not the mechanism NDB uses for this assignment.

Question 48Deployment, Installation, and Initial Configuration

Which action should be taken immediately after deploying the NDB server VM to make it operational?

  1. Install a database engine on it
  2. Convert it to a protection domain
  3. Attach it to an Objects bucket
  4. Register it with Prism Central and complete initial configuration Correct answer.

Explanation

After deployment, the NDB server must be registered with Prism Central and configured before it can manage databases. Objects attachment, protection domain conversion, and hosting a database engine on the NDB server are not part of making it operational.

Question 49Deployment, Installation, and Initial Configuration

An administrator observes that NDB cannot provision to a newly added cluster even though the cluster appears in Prism Central. What is the most likely cause?

  1. The cluster has more than three nodes
  2. The cluster has not been registered in NDB Correct answer.
  3. The cluster lacks an Objects bucket
  4. The cluster has too many protection domains

Explanation

A cluster visible in Prism Central is not automatically available to NDB; it must be registered in NDB so the server can manage it. Protection domain count, Objects presence, and node count do not prevent NDB registration.

Question 50Deployment, Installation, and Initial Configuration

Which sequence correctly reflects the high-level order of NDB initial setup?

  1. Register clusters, deploy Prism Central, then deploy the NDB server
  2. Define profiles, deploy Prism Central, then register the NDB server
  3. Deploy the NDB server, register it with Prism Central, register clusters, then define profiles Correct answer.
  4. Provision a database, then deploy the NDB server, then register Prism Central

Explanation

Initial setup begins with deploying the NDB server, registering it with Prism Central, registering the target clusters, and then defining profiles used for provisioning. Provisioning databases precedes none of these steps, and Prism Central must exist before NDB can register to it.
