Nutanix Certified Professional - Database Automation (NCP-DB) v6.5 Sample Questions (Q153-Q158):

NEW QUESTION # 153
An administrator is attempting to enable high availability (HA) for NDB across three Nutanix clusters located in separate data centers. If the network latency between two clusters exceeds 25ms RTT, what impact might this have on the NDB HA setup?

A. HA will operate with increased delay.
B. The clusters will not synchronize.
C. There will be no impact on HA functionality.
D. HA cannot be enabled due to the latency.

Answer: D

Explanation:
NDB supports high availability (HA) across multiple Nutanix clusters, including those in separate data centers, by replicating data and ensuring failover capabilities. However, NDB imposes strict network latency requirements for HA. The official documentation specifies that the round-trip time (RTT) latency between clusters should not exceed 25ms for HA to function effectively. If the latency between two clusters exceeds this threshold (e.g., due to geographic distance or network issues), HA cannot be enabled, as the synchronization and failover mechanisms rely on low-latency communication to maintain consistency and performance.
Impact of other options:
* A. HA will operate with increased delay: While latency might cause delays, exceeding 25ms RTT prevents HA setup entirely, not just delays its operation.
* C. The clusters will not synchronize: Synchronization issues may occur as a symptom, but the primary impact is HA enablement failure.
* D. There will be no impact on HA functionality: This is incorrect, as latency beyond 25ms RTT violates HA prerequisites.
Thus, the verified answer is B, reflecting NDB's latency constraints for HA across clusters.

NEW QUESTION # 154
An NDB administrator is looking to free up some space consumption in the container that NDB uses to manage a database landscape.
Where are two of the best locations within NDB that the administrator could view to see where the most storage is being consumed, in order to research for reclamation? (Choose two.)

A. NDB Dashboard and view the Clone Data Age in days.
B. View the Source Database grid to determine the size and status of registered databases.
C. View the Clone Database table to determine the Size and Last Refresh of clone databases.
D. View the Snapshot table in Time Machine to determine Reclaimable Space and Age of snapshots that have been taken.

Answer: C,D

Explanation:
To free up space in the NDB-managed container, the administrator needs to identify storage consumption sources. Two key locations in NDB provide actionable insights:
* C. Clone Database table: This displays all clone databases, including their Size (current storage usage) and Last Refresh (indicating age or staleness). Clones often consume significant space, and older or unused ones can be deleted to reclaim storage.
* D. Snapshot table in Time Machine: This shows snapshots with details like Reclaimable Space (space recoverable by deletion) and Age (how long snapshots have existed). Old or unnecessary snapshots are prime candidates for reclamation.
Why not the other options?
* A. NDB Dashboard (Clone Data Age): While it provides a high-level view, it lacks granular details (e.
g., size per clone) needed for targeted reclamation.
* B. Source Database grid: This shows registered databases' size and status but doesn't focus on derivative objects (clones/snapshots) that typically consume more space.
Thus, C and D are the best locations for detailed storage analysis and reclamation research.

NEW QUESTION # 155
A quality assurance team noticed a significant change between a cloned database they are currently using versus the one used one week ago. They created an SQL script to verify the differences.
Which task should be performed by an NDB administrator to provide the correct database to the QA team?

A. Create a clone database from a snapshot.
B. Perform a Log Catch Up operation.
C. Replicate a selected snapshot.
D. Clone database selecting Point in Time data.

Answer: D

Explanation:
When a quality assurance (QA) team notices a significant change between a cloned database currently in use and one used a week ago, and they have an SQL script to verify differences, the NDB administrator needs to provide a clone reflecting the database state from a week ago. The task "Clone database selecting Point in Time data" allows the administrator to select a specific point-in-time snapshot (e.g., from a week ago) using the Time Machine feature. This creates a new clone with the exact data state at that time, enabling the QA team to compare it with the current clone.
* Option A (Replicate a selected snapshot) is incorrect because replication is for HA, not creating a usable clone for QA.
* Option B (Create a clone database from a snapshot) is incorrect because it does not specify point-in- time selection, limiting flexibility to the latest snapshot.
* Option C (Clone database selecting Point in Time data) is correct as it allows precise selection of the week-old data state.
* Option D (Perform a Log Catch Up operation) is incorrect because Log Catch Up applies recent logs, not reverting to a past state.
This approach meets the QA team's need for historical data comparison.

NEW QUESTION # 156
A database administrator is tasked with creating a new clone of a running SQL database. During the clone process, there are no authorized servers are available.
What should the administrator do next?

A. Click the Action icon to authorize one or more database server VMs.
B. Click the Skip icon and choose to authorize later.
C. Register or provision a new authorized server VIVI.
D. Register or provision a new database VIVI

Answer: A

Explanation:
In the Nutanix Database Automation (NCP-DB) process, when a database administrator is tasked with creating a new clone of a running SQL database and there are no authorized servers available, the administrator should click the Action icon to authorize one or more database server VMs1. This is because the Nutanix Database Service (NDB) requires authorized servers to perform operations such as cloning1. The authorization process allows the NDB to manage and perform operations on the database server VMs1.

NEW QUESTION # 157
An administrator is trying to register a database server VM with NDB.
Which file types will prevent the registration from being successful if located in the C: drive?

A. System
B. Page
C. Backup
D. Database

Answer: B

Explanation:
Page files are temporary files that Windows uses to store data that does not fit in the physical memory. Page files can interfere with the registration of a database server VM with NDB, as they can cause errors or performance issues. Therefore, page files shouldbe located in a separate drive or partition from the C: drive, where the NDB agent and other files are installed. System, database, and backup files do not prevent the registration of a database server VM with NDB, as long as they are not corrupted or incompatible with the NDB requirements. References:
