NEW QUESTION # 243
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?
Answer: B
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.
Other options are incorrect or incomplete:
* A. Create a Maintenance window schedule and associate the SQL server with that maintenance window in the Database VM Menu: Maintenance windows manage downtime, not patch application for databases.
* B. Apply the patch to the database VM then create a new software profile using that updated VM as the source: This manual approach bypasses NDB's structured patching and lacks version control.
* C. 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: This is overly complex and risky, as manually patching a VM first can lead to inconsistencies.
Thus, the verified answer is D, aligning with NDB's best practices for database patching.

NEW QUESTION # 244
A new web application performs up to 200 concurrent connections to a PostgreSQL database. An administrator needs to configure the system to provision those DB servers.
Which action would easily help the administrator achieving this goal?
Answer: D
Explanation:
A new web application with up to 200 concurrent connections to a PostgreSQL database requires a robust and scalable configuration. Provisioning a PostgreSQL HA (High Availability) instance in NDB is the most effective action to achieve this goal. An HA instance leverages replication (e.g., streaming replication) to distribute load and ensure availability, accommodating high concurrency by allowing multiple nodes to handle traffic. This approach simplifies configuration compared to manual scripting or parameter adjustments.
* Option A (Use Post Create Command when provisioning the DB) is incorrect because post-create commands are for custom scripts, not optimal for handling concurrent connections.
* Option B (Create a new Database Parameters profile) is incorrect because while it can tune settings, it's less efficient than HA for scaling concurrency.
* Option C (Edit the API equivalent shell script) is incorrect as it's a manual and error-prone method compared to HA provisioning.
* Option D is correct because a PostgreSQL HA instance natively supports high concurrency and availability.
Note: The typo "PostqreSQL" is assumed to mean "PostgreSQL."

NEW QUESTION # 245
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?
Answer: D
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. References:

NEW QUESTION # 246
An administrator needs to patch an Oracle Database Server VM and must ensure Grid home is allocated sufficient storage space.
At a minimum, how much space must be available for Grid home prior to completing this task?
Answer: B
Explanation:
When patching an Oracle Database Server VM, it's important to ensure that there is sufficient storage space allocated for the Grid home. A minimum of 10GB space is required for this purpose to accommodate the patching process without storage constraints.References:Nutanix Database Automation documentation, particularly in the sections discussing Oracle database server VM management and patching requirements.
NEW QUESTION # 247
Refer to the exhibit.
A request is received to provision a new Oracle SIHA DB & VM to test ASMLIB on OEL79 and Oracle 19c.
When walking through the provisioning workflow, only ASMFD is available in the ASM Driver drop down.
What is necessary to provision the requested SIHA DB and DB VM with ASMLIB?
Answer: D
Explanation:
In the context of Nutanix Database Automation (NCP-DB), when provisioning a new Oracle SIHA DB & VM, if only ASMFD is available in the ASM Driver drop-down, it indicates that ASMLIB is not included in the current software profile. To provision the requested SIHA DB and DB VM with ASMLIB, it's essential to update the software profile to include the ASMLIB driver. This action will enable ASMLIB as an option in the ASM Driver drop-down during the provisioning workflow.
