100-140 Question 318
Single answerA company is running several virtual machines (VMs) on a Type 1 hypervisor to host its critical applications. One of the VMs is experiencing degraded performance. As an IT support technician, what is the BEST initial step to troubleshoot the issue?
- A
Check the resource allocation for the VM on the hypervisor
- B
Restart the virtual machine to clear any temporary issues
- C
Upgrade the hypervisor software to the latest version
- D
Migrate the VM to another physical server immediately
Show answer and explanation
Correct answer: A
Explanation
The best initial step for troubleshooting a VM experiencing degraded performance is to check its resource allocation on the hypervisor. This allows the technician to determine if the VM is constrained by CPU, memory, or storage resources. Addressing resource allocation issues is often the quickest and most efficient way to resolve performance problems, making it the most logical first step.
- A. Correct.
Checking the resource allocation is the best initial step, as it allows you to identify if the VM is experiencing resource contention (e.g., CPU, RAM, or storage) on the hypervisor.
- B. Incorrect.
Restarting the VM might temporarily resolve the issue, but it does not address the root cause of the degraded performance and is not the best initial step.
- C. Incorrect.
Upgrading the hypervisor is a complex task that should only be done after confirming it is necessary. It is not relevant as an initial troubleshooting step.
- D. Incorrect.
Migrating the VM to another server could help, but it should only be considered after identifying the cause of the issue. This is also not the best initial step for troubleshooting.
