Question 1

An Object store is registered with the NDB control plane and an administrator tries to register a database without explicitly specifying the Object store for the log drive.

What will be the result?

AThe operation will use the first reachable Object store.

BThe operation will not use the Object store.

CThe operation use the Object store with high priority.

DThe operation will fail.

Answer : A

Question 2

An administrator needs to restore databases provisioned with a shared disk configuration on Windows Storage Spaces.

What happens when NDB runs the restore operation?

ANDB restores the disks that are associated with the database.

BNDB copies the DB files to be restored to the source volume.

CNDB replaces the source volume with the snapshot volume.

DNDB performs Tail Log backup to backup any remaining logs.

Answer : A

Question 3

When triggering an in-place restore of a multi-node PostgreSQL HA cluster through NDB to a previous point-in-time, how does NDB handle the Patroni consensus layer during the recovery process?

ANDB promotes all cluster nodes to simultaneous read-write primary leaders to accelerate the ingestion of archived transaction logs.

BNDB leaves Patroni fully active so it can stream live application traffic to the standby nodes while the primary is being overwritten.

CNDB temporarily pauses Patroni cluster monitoring and puts the cluster in maintenance mode during the restore operation.

DNDB deletes the Patroni configuration and recreates it from backup after the restore has completed.

Answer : C

Question 4

How does NDB's Time Machine process the recovery when the transaction history spans multiple archived redo log switches?

ANDB relies on Oracle RMAN to isolate the container-level redo streams and replays changes targeting only the specified PDB metadata.

BNDB ignores the shared container redo logs and applies flat text backup files directly into the target database directory layout.

CNDB utilizes the native Nutanix Prism Central Cassandra framework to reconstruct the relational transaction histories across hosts.

DNDB prompts the administrator to execute automated shell scripts on the OS command line to append missing block structures.

Answer : A

Question 5

An administrator enables NDB High Availability.

What happens if the active NDB API service becomes unavailable?

AExisting databases stop accepting client connections.

BDatabase patch operations are canceled automatically.

CDatabase backup schedules are suspended until recovery is performed.

DStandby NDB service assumes management responsibilities.

Answer : D

Question 6

An administrator is preparing to deploy NDB with High Availability (HA) configuration so that the NDB control plane is distributed across different sites in case of a failure at the primary DC.

Which prerequisite must be met before attempting to enable the HA feature?

ARound-trip time of less than 25 ms

BMinimum of two cluster topology

CMinimum of three AHV Clusters

DRound-trip time of less than 5 ms

Answer : D

Question 7

An administrator has deployed an NDB HA setup. An electrical maintenance window needs to be planned and the clusters where NDB is deployed must be powered off.

After shutting down the load balancer server, what should the administrator do next?

ARun the sudo systemctl stop patroni command.

BRun the high-availability list command.

CShutdown the API leader node.

DShutdown the API standby node.
