2V0-21.23 Question 315
Select 3A VMware administrator notices that a virtual machine (VM) is experiencing high CPU usage but is unsure of the root cause. They need to identify if the issue is related to resource contention in the cluster or if the VM is simply demanding more CPU resources. Which resource monitoring tool(s) should the administrator use to diagnose the issue effectively?
- A
vSphere Client Performance Charts
- B
esxtop or resxtop
- C
VMware Aria Operations (formerly vRealize Operations)
- D
VMware Update Manager
- E
Resource Allocation tab in the vSphere Client
Show answer and explanation
Correct answers: A, B, C
Explanation
To diagnose high CPU usage effectively, administrators need tools that provide insights into the VM's CPU consumption and whether the host or cluster is experiencing contention. vSphere Client Performance Charts offer a basic overview, while esxtop provides real-time, detailed metrics. VMware Aria Operations adds advanced analytics and trend analysis for proactive monitoring. VMware Update Manager and the Resource Allocation tab do not directly aid in diagnosing performance problems, making them unsuitable for this scenario.
- A. Correct.
vSphere Client Performance Charts provide a quick overview of the VM's resource usage, including CPU, memory, disk, and network. They can help determine if the CPU is being over-utilized or constrained.
- B. Correct.
esxtop or resxtop is a real-time command-line tool that provides in-depth insights into resource usage and contention at the VM and host levels. It is particularly useful for diagnosing performance issues related to CPU, memory, and disk.
- C. Correct.
VMware Aria Operations offers advanced analytics and historical data to help identify trends and potential resource contention. It provides a comprehensive view of both the VM and the cluster's performance.
- D. Incorrect.
VMware Update Manager is used for patch management and does not provide resource monitoring capabilities.
- E. Incorrect.
The Resource Allocation tab in the vSphere Client shows resource limits, reservations, and shares but does not provide real-time or historical performance monitoring data to diagnose CPU issues.
