A workload needs more CPU and memory than the current Azure VM size provides. The administrator wants to increase compute capacity without redeploying the application. What should be done?

Move the VM into an availability set

An availability set improves resiliency, but it does not increase the CPU or memory available to the VM.

Replace the VM with a snapshot

A snapshot is for disk recovery, not for adding more compute resources to a running workload.

Assign a user-assigned managed identity

A managed identity helps with access to Azure services, but it does not change VM performance capacity.

What does this AZ-104 question test?

Authentication checks who the user is.

What is the correct answer to this question?

The correct answer is: Resize the VM to a larger size — Resizing the VM is the correct action when the workload needs more CPU or memory. Azure lets you change the VM size to a larger SKU, which increases compute capacity while keeping the VM as the same resource. That makes it the simplest and most direct way to address resource pressure without rebuilding the application or moving it to a different service. Why others are wrong: An availability set affects resilience, not compute performance. A snapshot is a disk copy used for recovery, so it cannot add CPU or memory. A managed identity is only for authorization to Azure resources and has no effect on the VM's size or performance.

What should I do if I get this AZ-104 question wrong?

Then try more questions from the same exam bank and focus on understanding why the wrong options are tempting.
