2V0-21.23 Question 438
Select 3You are tasked with creating a custom alarm in vSphere to monitor datastore disk usage. The alarm should trigger when the datastore free space drops below 20%. During configuration, which of the following actions and settings must be performed to ensure the alarm functions as required?
- A
Set the alarm type to 'Monitor Datastore'.
- B
Define a condition using 'Datastore Usage on Disk' metric.
- C
Configure the trigger condition to check if 'Free Space (%)' is less than 20.
- D
Assign a critical severity level for the alarm when the condition is met.
- E
Set the alarm to monitor host memory usage.
Show answer and explanation
Correct answers: B, C, D
Explanation
To create a custom alarm for monitoring datastore free space, you need to select the correct metric ('Datastore Usage on Disk'), define the condition ('Free Space (%) < 20'), and set an appropriate severity level (e.g., Critical) for proper alerting. Choosing unrelated metrics or settings, such as host memory usage, would result in an incorrect alarm configuration.
- A. Incorrect.
This option is incorrect because the alarm type should be set based on datastore metrics, but there’s no specific 'Monitor Datastore' option. Instead, the alarm type is set by selecting the desired object and metric.
- B. Correct.
This option is correct as the 'Datastore Usage on Disk' metric is required to monitor datastore usage. It provides the necessary data for creating a threshold-based custom alarm.
- C. Correct.
This option is correct because configuring a trigger condition to monitor 'Free Space (%)' and setting it to less than 20 ensures the alarm activates when free space drops below the threshold.
- D. Correct.
This option is correct as assigning a critical severity level ensures proper visibility and action in response to the alarm triggering.
- E. Incorrect.
This option is incorrect because monitoring host memory usage is unrelated to monitoring datastore free space. Selecting this would lead to an incorrect configuration.
