2V0-21.23 Question 341
Single answerA VMware administrator notices that a virtual machine is experiencing performance degradation. The administrator wants to determine if CPU contention is causing the issue. Which performance chart in vSphere Client would be the most appropriate to analyze this problem?
- A
CPU Usage (MHz) chart
- B
CPU Ready Time chart
- C
Memory Consumed (MB) chart
- D
Network Packets Transmitted chart
Show answer and explanation
Correct answer: B
Explanation
The CPU Ready Time chart is the most relevant performance chart for diagnosing CPU contention issues. High CPU Ready Time indicates that the virtual machine is waiting for CPU resources, which can cause performance degradation. By analyzing this chart, the administrator can confirm whether CPU contention is the root cause of the issue.
- A. Incorrect.
The CPU Usage (MHz) chart shows the amount of CPU resources consumed but does not provide insights into CPU contention or scheduling delays.
- B. Correct.
The CPU Ready Time chart indicates the amount of time a virtual machine's CPU was ready to run but could not due to lack of physical CPU resources. This is a key metric for identifying CPU contention issues.
- C. Incorrect.
The Memory Consumed (MB) chart helps monitor memory usage but does not provide information related to CPU contention or performance degradation caused by CPU issues.
- D. Incorrect.
The Network Packets Transmitted chart is used to analyze network performance and is unrelated to CPU contention or performance issues.
