2V0-32.24 Question 219
Single answerYour organization uses VMware Aria Operations (formerly vRealize Operations) to monitor a multi-cloud environment. The team has noticed performance degradation in a critical application running on a virtual machine. Upon reviewing the metrics collected by VMware Aria Operations, you identify high CPU Ready Time and memory ballooning on the virtual machine. Which of the following actions would best address the issue?
- A
Increase the CPU and memory resources allocated to the virtual machine.
- B
Migrate the virtual machine to a host with less CPU contention.
- C
Disable memory ballooning in the guest operating system.
- D
Restart the virtual machine to clear resource contention.
Show answer and explanation
Correct answer: B
Explanation
High CPU Ready Time and memory ballooning indicate that the virtual machine is experiencing resource contention on the host. Migrating the virtual machine to a host with less contention helps resolve the issue by providing it with access to sufficient physical resources. Options such as increasing resources or restarting the virtual machine do not address the root cause, and disabling memory ballooning could lead to adverse effects.
- A. Incorrect.
Increasing CPU and memory resources may not resolve the issue if the host itself is already overloaded or experiencing contention. This action only addresses the virtual machine's resource limits but not the underlying host contention.
- B. Correct.
Migrating the virtual machine to a host with less CPU contention is the best option because it directly addresses the high CPU Ready Time, which is typically caused by contention for physical CPU resources on the host. This action helps improve performance without changing the virtual machine's configuration.
- C. Incorrect.
Disabling memory ballooning is not recommended as it is a normal vSphere mechanism to manage memory efficiently. Disabling it could lead to worse memory management and is not a solution to the observed issue.
- D. Incorrect.
Restarting the virtual machine might temporarily alleviate the problem, but it does not address the root cause of the performance issue (host contention). This is a temporary fix rather than a long-term solution.
