NEW QUESTION # 152
Refer to the exhibit. An administrator is receiving critical NDB email alerts regarding storage for the DBA database, which is a member of a database group.
How would the administrator remediate the issue within NDB?
- A. From the Alerts page, select the alert, choose Set Status to Resolved, and Scale the storage via the Resolve Now dialogue box.
- B. From Prism Central, add additional storage to the VM, then expand the log storage via the database tools.
- C. From the Databases page, select the Database group and Scale the storage from the Database Actions menu.
- D. From the Database Summary page for the DBA database, use the Scale option to grow the storage accordingly.
Answer: D
Explanation:
The administrator can remediate the issue of critical storage alerts by scaling up the storage directly from the Database Summary page for that specific DBA database. This action allows for an increase in storage capacity to alleviate space constraints and prevent future critical alerts related to storage space. The other options are not correct, as they either involve scaling the entire database group, which may not be necessary or desired, or require additional steps outside of NDB, which may not be feasible or efficient.

An administrator selected Bronze SLA for Era Time Machine during database registration. Which two capabilities are supported by the Time Machine for this database? (Choose two,)
- A. Cloning
- B. Snapshots
- C. Log Catch up
- D. Provwonng
Answer: B,C
Explanation:
The Nutanix Era Time Machine provides various capabilities depending on the Service Level Agreement (SLA) selected during database registration. For a database with a Bronze SLA, the Time Machine supports both "Log Catch up" and "Snapshots". "Log Catch up" allows the Time Machine to keep up with the latest changes in the database by capturing log data. "Snapshots" are point-in-time copies of the database that can be used for recovery or cloning.
NEW QUESTION # 156
An administrator needs to roll back an Oracle patch on a database server VM using NDB. What is required for this action to be successful?
- A. The database must be shut down.
- B. The database must be in read-only mode.
- C. The patch must have been applied using NDB.
- D. The patch must have been applied on Grid home only using NDB.
Answer: C
Explanation:
To roll back an Oracle patch on a database server VM using NDB, the patch must have been applied using NDB in the first place. This is because NDB maintains a patch inventory and history for each database server VM and database that it manages. NDB uses this information to determine which patches can be rolled back and how to revert the changes made by the patch. If the patch was applied outside of NDB, NDB would not have the patch information and would not be able to roll back the patch. Therefore, the patch must have been applied using NDB for the rollback action to be successful. The other options are not required for the rollback action. The database does not need to be shut down or in read-only mode, as NDB can perform the rollback operation online. The patch does not need to be applied on Grid home only, as NDB can roll back patches applied on both Grid home and Database home.
NEW QUESTION # 157
A Log Catchup gap has occurred, impacting the ability to perform point-in-time restore (PITR) operations to create a clone or perform a database restore. Which two statements below are true for the NDB Time Machine Heal Snapshot feature? (Choose two.)
- A. Manual Heal is only used when gaps in Log Catchup are detected once the operation has begun failing.
- B. Once a Time Machine Heal process has been invoked and successful, the Log Catchup gap can be spanned for a PITR operation.
- C. By default the time machine auto-heal feature is enabled.
- D. Time Machine auto-heal runs on the NDB server every 5 minutes and checks for different cases that require a heal.
Answer: B,D
Explanation:
A Log Catchup gap in Nutanix Database Service (NDB) occurs when transaction logs are missing or corrupted, disrupting point-in-time restore (PITR) operations for cloning or database restoration via Time Machine. The NDB Time Machine Heal Snapshot feature addresses this by repairing snapshots to resolve such gaps.
NEW QUESTION # 158

- A. Infrastructure Scaling (DB Server VM expansion)
- B. Compute Profile Migration
- C. HA Policy Manager
- D. Time Machine Restore
Answer: A
Explanation:
NDB supports automated scaling of DB Server VMs-CPU, memory, or storage expansion-while coordinating required database adjustments.
NEW QUESTION # 159
An administrator needs to migrate a large 1/0-intensive database that doesn't support multi-disk layout.
How should the storage be provisioned with Era to support the database while optimizing performance?
- A. Volume Group
- B. Volume Group with Load Balancing
- C. Storage Spaces
- D. vDisk based provisioning
Answer: A
Explanation:
In Nutanix Era, a Volume Group is the recommended storage provisioning method for a large I/O- intensive database that doesn't support a multi-disk layout. A Volume Group in Nutanix Era is a collection of disks that can be managed as a single entity, providing a way to aggregate the storage capacity of multiple disks into a larger storage unit. This allows for better performance optimization as it enables the database to leverage the combined I/O capabilities of all the disks in the group. It's important to note that while other options like Load Balancing, Storage Spaces, and vDisk based provisioning can also be used in certain scenarios, a Volume Group is specifically designed for situations where a single, high-performance storage unit is required.
NEW QUESTION # 160
What are two status values that can be set within the Alerts Dashboard? (Choose two.)
- A. Acknowledged
- B. Data Resiliency
- C. Resolved
- D. Auto
Answer: A,C
Explanation:
The correct answer is B and D because these are the two status values that can be set within the Alerts Dashboard in NDB. Resolved means that the alert has been fixed and no longer requires attention. Acknowledged means that the alert has been seen and is being worked on. Option A is incorrect because Auto is not a status value, but a mode that automatically resolves alerts based on predefined rules. Option C is incorrect because Data Resiliency is not a status value, but a feature that ensures the availability and integrity of the data in NDB.
NEW QUESTION # 161
A user wants to apply the latest OS security patches on a Windows server.
How should the user accomplish this task?
- A. Update the database.
- B. Create and apply a Maintenance Plan in NDB.
- C. Use update functionality directly on the VM
- D. Reboot the system.
Answer: B
Explanation:
To apply the latest OS security patches on a Windows server managed by NDB, the user should create and apply a Maintenance Plan within the NDB interface. NDB provides a Maintenance Plan feature that allows administrators to schedule and automate OS patching for database server VMs, ensuring patches are applied in a controlled manner without disrupting database operations. This includes validating the patch process, rolling back if needed, and maintaining compliance with security standards. The plan can be configured to target the specific Windows server and include the latest security updates from Microsoft.
NEW QUESTION # 162
An administrator has been tasked to deploy Microsoft SQL servers in an Active Directory environment, selecting a specific service account to start up the database.
Which configuration should be set?
- A. Database parameters
- B. Compute profile
- C. Windows domain profile
- D. Sysprep Windows image
Answer: C
Explanation:
To deploy Microsoft SQL Servers in an Active Directory (AD) environment and select a specific service account to start up the database, the administrator must configure a Windows domain profile in NDB. A Windows domain profile defines the AD integration settings, including the service account credentials (e.g., username and password) that NDB uses to authenticate and manage the SQL Server instances. This configuration ensures the database starts and runs under the specified AD service account, aligning with enterprise security policies.
NEW QUESTION # 163
An administrator manages an multi-cluster NDB instance with HA enabled. After failure, more than one API server VM is down. How should the administrator restore full functionality?
- A. Call Nutanix support to reset all API server connections.
- B. Restart all database server VMs as NDB HA only tolerates single API server failure.
- C. Ensure at least one API server VM is online; the rest will recover automatically.
- D. Manually distribute connections across remaining clusters.
Answer: C
Explanation:
In a multi-cluster NDB instance with HA enabled, the NDB architecture includes multiple API server VMs to ensure availability. If more than one API server VM is down after a failure, the administrator should ensure at least one API server VM is online. NDB's HA design tolerates multiple API server failures as long as one remains operational, and the remaining VMs will recover automatically through the HA failover mechanism. This leverages Nutanix's distributed architecture and self-healing capabilities to restore full functionality without manual intervention beyond ensuring one VM is running.
NEW QUESTION # 164
It becomes necessary to remove an existing database clone. "To minimize the impact of that removal to users, an administrator would like to schedule this operation for weekend hours. When scheduling this removal, other than the specified date/time, which option in the Update Removal Schedule is pre-selected as non-optional?
- A. Delete the database clone from the VM.
- B. Delete supporting snapshot from NDB.
- C. Create an alert before removal.
- D. Unregister the database clone from NDB.
Answer: B
Explanation:
When an administrator schedules the removal of an existing database clone to minimize user impact (e.g., during weekend hours), the "Update Removal Schedule" feature in NDB allows for planning the operation. Among the options, the "Delete supporting snapshot from NDB" is pre- selected as a non- optional action. This ensures that the snapshot data associated with the clone is removed along with the clone itself, maintaining storage efficiency and consistency in the Time Machine framework. Other options may be selectable but are not mandatory by default.
NEW QUESTION # 165
An administrator wants to apply patches to the Microsoft SQL Server databases in an NDB environment.
What needs to be done in NDB to accomplish this?
- A. Create a new software profile version with the downloaded cumulative update from Microsoft, publish the updated software profile, then apply the update under the database VM Menu for each database server.
- B. Apply the patch to the database VM, then create a new software profile version using that updated database VM as the source, publish the updated software profile then apply that patch under the database VM Menu for each database server.
- C. Apply the patch to the database VM then create a new software profile using that updated VM as the source.
- D. Create a Maintenance window schedule and associate the SQL server with that maintenance window in the Database VM Menu.
Answer: A
Explanation:
To apply patches to Microsoft SQL Server databases in an NDB environment, the administrator should follow a structured process:
Create a new software profile version: Download the latest cumulative update (CU) or patch from Microsoft and use it to create a new version of the existing SQL Server Software Profile in NDB.
This ensures the patch is integrated into NDB's management framework.
Publish the updated software profile: Promote the new version to "Published" status, making it available for use across the environment.
Apply the update: Navigate to the "Database VM Menu" for each database server, select the updated software profile, and apply the patch. This automates the patching process while maintaining database consistency and allowing rollback if needed.
NEW QUESTION # 166
When an administrator no longer wants to use a software profile version, what happens when it is deprecated?
- A. Any database server using that profile will by updated to the latest software profile.
- B. It can be used in provisioning.
- C. It can no longer be used for provisioning.
- D. Any database server using that software profile can no longer be patched.
Answer: C
Explanation:
In Nutanix Database Service (NDB), when an administrator deprecates a software profile version, it is marked as obsolete and restricted from certain operations. Specifically, a deprecated software profile version can no longer be used for provisioning new database instances or VMs.
This ensures that only current, supported versions are utilized for new deployments, maintaining consistency and security. Existing database servers using the deprecated profile can continue to operate and may still be patched (if updates are compatible), but the profile itself is excluded from future provisioning tasks.
NEW QUESTION # 167
While restoring a PostgreSQL HA instance, an administrator notices that the restore of a standby node has failed. The primary node is ready to seive application traffic.
In what state does NDB leave the database?
- A. OFFLINE
- B. RECOVERY PENDING
- C. PAKFIAL.READY
- D. ONLINE
Answer: D
Explanation:
When restoring a PostgreSQL HA instance in NDB, if the standby node fails to restore but the primary node is successfully restored and ready to serve application traffic, NDB considers the database operational from the perspective of the primary node. In this scenario, NDB leaves the database in an "ONLINE" state, reflecting that the primary node is functional and capable of handling requests, even though the HA configuration is not fully intact due to the standby failure.
The administrator would need to address the standby node separately (e.g., by re-provisioning or troubleshooting), but the database's state is determined by the primary node's readiness.
NEW QUESTION # 168
The NDB user interface can display which language option?
- A. French
- B. Korean
- C. Japanese
- D. German
Answer: C
Explanation:
The NDB user interface supports multiple languages, including English, Chinese, and Japanese.
You can change the language pReference: in the NDB settings page. The NDB user interface does not support Korean, French, or German languages at this time.
NEW QUESTION # 169
An Era-managed production MSSQL database crashed during a busy holiday weekend and the administrator has to restore the database to the most recent timestamp with an objective to reduce the restore time and minimize data loss. What option should the administrator do to achieve this objective?
- A. Perform Restore Source Database by selecting Restore time just before the database crash.
- B. Perform Restore Source Database by selecting the available snapshot.
- C. Perform Restore Source Database by selecting most recent and include Tail log Backup
- D. Perform Restore Source Database by selecting the current time.
Answer: C
Explanation:
Nutanix Era is a database management solution that automates and simplifies database administration tasks such as provisioning, patching, cloning, and backup. In the event of a database crash, the most effective way to minimize data loss and reduce restore time is to perform a restore of the source database by selecting the most recent point in time and including the Tail log Backup. The Tail log Backup includes all the transactions that have occurred since the last transaction log backup, which helps to minimize data loss. By selecting the most recent point in time for the restore, the administrator ensures that the database is restored to the state it was in just before the crash, thereby reducing the amount of data that needs to be reprocessed or reentered. This approach aligns with the Nutanix Era's capabilities and best practices for database recovery.
NEW QUESTION # 170
If an administrator wants to store database backups on an external repository, which option should be configured?
- A. DR Site Mirror
- B. External Snapshot Repository (e.g., NFS)
- C. AOS Volume Group
- D. Archive Tier on Object Store
Answer: B
Explanation:
Time Machine allows backups to be exported to external repositories such as NFS or S3- compatible storage for long-term or off-cluster retention.
NEW QUESTION # 171
In NDB, which two Time Machine options are available when creating a database clone? {Choose two.)
- A. Restore point
- B. Snapshot
- C. Point in time
- D. Backup
Answer: B,C
Explanation:
The correct answer is A and D because these are the two Time Machine options that are available when creating a database clone in NDB. Point in time allows the user to specify a date and time to create a clone from a specific point in the database history. Snapshot allows the user to select a previously taken snapshot to create a clone from a consistent state of the database.
Option B is incorrect because Restore point is not a Time Machine option, but a feature that allows the user to restore a source database to a previous point in time. Option C is incorrect because Backup is not a Time Machine option, but a feature that allows the user to backup a database to a remote location.
NEW QUESTION # 172
An administrator must be able to restore databases based on very strict SLAs, but is facing multiple bottlenecks when storing log backups of databases on NDB Agents. What can the administrator do to alleviate these issues?
- A. Integrate NDB with AWS S3 or Azure Blob storage for storing log backups.
- B. Add additional NDB Agent VMs.
- C. Increase the RAM and CPU on the NDB Agent VMs.
- D. Integrate NDB with Nutanix Objects for storing log backups.
Answer: D
Explanation:
NDB Agents handle log backups for database instances, but storing these backups locally can lead to bottlenecks (e.g., disk I/O, storage capacity). To alleviate this, integrating NDB with Nutanix Objects is the recommended solution. Nutanix Objects is an S3-compatible object storage service within the Nutanix ecosystem, ideal for offloading log backups from NDB Agents to a scalable, centralized storage platform. This reduces local storage pressure, improves performance, and ensures strict SLAs for database recovery by leveraging efficient backup retrieval.
