Nutanix Certified Professional - Database Automation (NCP-DB) v6.5 認定 NCP-DB 試験問題 (Q86-Q91):

質問 # 86
What are two status values that can be set within the Alerts Dashboard? (Choose two.)

A. Auto
B. Data Resiliency
C. Resolved
D. Acknowledged

正解：C、D

解説：
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.

質問 # 87
An administrator has noticed that the automatic snapshot and log catch-up (automatic and manual) activities for a Time Machine are halted and manual snapshots cannot be created.
What status is this Time Machine in?

A. PAUSED
B. OFFLINE
C. FROZEN
D. READY

正解：A

解説：
In NDB, a Time Machine manages snapshots and log catch-up operations for database protection and recovery. The scenario describes a Time Machine where automatic snapshot and log catch-up activities (both automatic and manual) are halted, and manual snapshots cannot be created. This indicates the Time Machine is in a PAUSED state.
In NDB, the Time Machine states are:
* FROZEN: A temporary state during specific operations (e.g., cloning), but it doesn't halt all activities permanently.
* OFFLINE: Indicates the Time Machine is unavailable or not operational, often due to connectivity or configuration issues, but this typically prevents access rather than just halting operations.
* PAUSED: Explicitly stops all scheduled and manual snapshot/log activities, often manually triggered by an administrator or due to an error condition (e.g., resource constraints). Operations resume when unpaused.
* READY: The normal operational state where snapshots and log catch-ups occur as scheduled.
Given the inability to create manual snapshots alongside halted automatic operations, PAUSED is the most fitting status, as it reflects an intentional or enforced suspension of activities.

質問 # 88
For supported Linux based database VM's managed by NDB, how would an administrator keep software profiles updated for provisioning new database VMs?

A. Create a Maintenance window under the policy menu, then under Database VM, add the database VMs to that maintenance window and check both Database and Operating system updates.
B. In the Administrator menu drop down, go the Maintenance tab and choose Download Upgrade
C. Associate the newly provisioned database VMs with a maintenance window so they are keep updated.
D. Apply patches to a database VM for each supported database engine, then create a new software profile version for each supported database VM for each one using the updated database VM as the source.

正解：D

解説：
For supported Linux-based database VMs managed by NDB, keeping software profiles updated for provisioning new database VMs requires a structured process. The administrator must first apply the necessary patches (e.g., OS updates and database engine patches) to an existing database VM for each supported database engine (e.g., PostgreSQL, Oracle). Then, a new software profile version must be created using the updated VM as the source. This new version captures the patched configuration and can be used to provision new VMs, ensuring they are deployed with the latest updates.
* Option A (Create a Maintenance window under the policy menu, then under Database VM, add the database VMs to that maintenance window and check both Database and Operating system updates) is incorrect because a Maintenance Window schedules updates for existing VMs, not for updating software profiles for new provisions.
* Option B (Apply patches to a database VM for each supported database engine, then create a new software profile version for each supported database VM for each one using the updated database VM as the source) is correct as it follows the standard NDB process for profile updates.
* Option C (Associate the newly provisioned database VMs with a maintenance window so they are kept updated) is incorrect because this applies to ongoing maintenance, not initial profile updates for provisioning.
* Option D (In the Administrator menu drop down, go the Maintenance tab and choose Download Upgrade) is incorrect because downloading upgrades is part of the patch process, not the profile creation step.
This method ensures new VMs are provisioned with the latest software configurations.

質問 # 89
Nutanix NDB gives an administrator the ability to create highly-available database pairs with which two databases? (Choose two.)

A. MySQL
B. SQL Server
C. MariaDB
D. PostgreSQL

正解：B、D

解説：
Nutanix NDB provides the ability to create highly-available (HA) database pairs, leveraging replication and failover across clusters. The two databases explicitly supported for HA pairs in NDB are PostgreSQL and SQL Server. NDB orchestrates HA for PostgreSQL using streaming replication and for SQL Server using Always On Availability Groups or Failover Cluster Instances, ensuring data redundancy and failover capabilities across Nutanix clusters.
Other options are not supported for HA pairs:
* A. MySQL: MySQL is supported by NDB but lacks native HA pair configuration.
* D. MariaDB: Similar to MySQL, MariaDB is managed by NDB but does not support HA pairs.
Thus, the verified answers are B and C, reflecting NDB's HA capabilities.

質問 # 90
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 Database Summary page for the DBA database, use the Scale option to grow the storage accordingly.
B. From the Databases page, select the Database group and Scale the storage from the Database Actions menu.
C. From Prism Central, add additional storage to the VM, then expand the log storage via the database tools.
D. From the Alerts page, select the alert, choose Set Status to Resolved, and Scale the storage via the Resolve Now dialogue box.

正解：A

解説：
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 space1. 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.
