4. Question
When provisioning a PostgreSQL HA instance, what are the minimum and maximum number of DB server VMs that can be deployed?
Correct
The minimum number of DB Server VMs that can be deployed in a PostgreSQL HA Instance is 3, and the maximum is 5. The minimum number of Database Server VMs that can be deployed in a PostgreSQL HA (High Availability) cluster is three.

Question 6 of 60
6. Question
An administrator must restore an Oracle database that recently failed to its state from the previous day. Which two restore options can be used? (Choose two.)
Correct
The two restore options that can be used are: Snapshot: A snapshot is a point-in-time copy of a database. Snapshots can be used to restore a database to a specific point in time, such as the prior day‘s state. Point in Time: A point-in-time recovery restores the database to a specific moment in the past using transaction logs. This allows for very granular restoration to a precise point in time, which could be set to the prior day‘s state.

Question 9 of 60
9. Question
Which NDB feature is responsible for collecting logs and snapshots from databases?
Correct
Nutanix Database Service (NDB) uses its Time Machine feature to collect snapshots and logs. The Time Machine combines these to enable Copy Data Management (CDM) functionality, including creating database clones and point-in-time recovery. Database logs are collected to a staging drive, then a snapshot is taken. The logs are copied to a dedicated log drive attached to the NDB server, enabling point-in-time cloning and recovery.

Question 10 of 60
10. Question
A DBA wants to replicate database snapshots to remote Nutanix clusters. What should be done to ensure Time Machine data availability across all registered Nutanix clusters in NDB?
Correct
To manage Time Machine data availability across all registered Nutanix clusters in NDB, the administrator needs to utilize Data Access Management (DAM) policies. DAM policies allow adding, updating, and removing Time Machine data accessibility across multiple registered clusters. Adding a DAM policy for a cluster associates the source database‘s Time Machine with that cluster, enabling snapshot operations (creation, replication, deletion) on the associated clusters.

Question 12 of 60
12. Question
An administrator is tasked with auditing NDB SLAs. What type of data will be reviewed?
Correct
When auditing Nutanix Database Service (NDB) SLAs, an administrator reviews data retention policies.

Question 13 of 60
13. Question
A development team has requested that an administrator provide them with a copy of the production Finance database. The business requires that any financial data be masked before being used in development.
How should the administrator create a clone with masked data for the development environment?
Correct
Nutanix NDB simplifies database operations like provisioning, cloning, and refreshing databases. NDB allows for applying scripts for data masking during the cloning process to protect sensitive data like financial information. As the provided documentation mentions, you can create space-efficient clones, meaning the clone shares data blocks with the parent until changes are made. This helps conserve storage when creating copies for development and testing. The masking script ensures that the copy of the production Finance database provided to the development team has the sensitive data masked.

Question 14 of 60
14. Question
Which statement best describes the outcome when a 3rd-party backup tool is selected to manage log backups for Microsoft SQL in NDB?
Correct
NDB utilizes copy-only backups (VSS-initiated snapshots) for database clones/restores. This approach prevents interference with the 3rd-party backup schedules and maintains the transaction log sequence. However, NDB will not support point-in-time recovery (PITR). It‘s important to note that using 3rd-party log backup solutions for NDB-managed databases is not recommended due to potential log sequence number (LSN) mismatch issues.

Question 15 of 60
15. Question
An administrator needs to restore a source database from a snapshot. The database shares its source volume with multiple other databases. How does NDB handle this restore operation?
Correct
NDB handles database restores on shared volumes by mounting the snapshot of the source volume and copying only the necessary database files to the original location. The other databases on the shared volume are not affected. This file-level copy operation takes longer than a full volume restore from a snapshot.

Question 17 of 60
17. Question
Which response lists two ways to upgrade an NDB Server?

An administrator needs to roll back an Oracle patch on a database server VM using NDB. What condition must be met for this action to be successful?
Correct
The patch must have been applied using NDB is the correct answer. NDB uses an out-of-place patching method. It clones the patched home from a template VM to the target Oracle server and migrates the database services to the new home. Rollback involves switching back to the original, pre-patch Oracle Home, which NDB retains. Using the Oracle OPatch rollback is not supported.1
