2V0-21.23 Question 437
Select 3An administrator is tasked with creating a custom alarm in vCenter Server to monitor a critical VM running a production database. The alarm should trigger when the VM's CPU usage exceeds 90% for 5 minutes or its memory usage exceeds 95%. Which configuration step is required to correctly create this alarm?
- A
Set the alarm type to 'Virtual Machine' and the triggers to 'CPU Usage' and 'Memory Usage'.
- B
Configure the condition to trigger if the CPU usage is 'greater than 90%' and the memory usage is 'greater than 95%'.
- C
Define the alarm scope as the specific VM hosting the production database.
- D
Set the actions to send an email notification and power off the VM when the alarm is triggered.
- E
Enable the 'Evaluate multiple conditions' option to combine CPU and memory usage conditions.
Show answer and explanation
Correct answers: A, B, C
Explanation
To create a custom alarm for a specific VM, the administrator must configure the alarm type, set the appropriate triggers and conditions, and define the scope to the intended VM. In this scenario, the alarm type must be 'Virtual Machine', the conditions should monitor CPU usage exceeding 90% and memory usage exceeding 95%, and the alarm scope must be set to the production database VM. Configuring actions like sending notifications can be optional, but powering off the VM is not a best practice for such alarms. The 'Evaluate multiple conditions' option is not necessary for this use case.
- A. Correct.
This is correct because the alarm type needs to be 'Virtual Machine' and the triggers must match the conditions you want to monitor, which are CPU and memory usage.
- B. Correct.
This is correct because the alarm condition must be set to trigger when CPU usage is greater than 90% and memory usage exceeds 95%.
- C. Correct.
This is correct because the scope of the alarm must be defined to apply only to the specific VM hosting the production database.
- D. Incorrect.
This is incorrect because powering off a critical VM is not a common or recommended action for high CPU or memory usage. Sending an email notification could be valid but is not specifically required in the scenario.
- E. Incorrect.
This is incorrect because the 'Evaluate multiple conditions' option is not required to monitor CPU and memory usage independently. Each trigger can be configured separately within the alarm.
