- A
Redeploy the VM.
Redeploying a VM instructs Azure to move it to new underlying infrastructure while preserving the VM resource and attached disks. It is a direct response when you suspect the current host is unhealthy.
- B
Delete the VM and recreate it from the OS disk.
Why wrong: Deleting and recreating the VM is destructive to the original VM resource and risks losing attached configuration, such as the NIC association and any operational state you want to preserve.
- C
Capture the VM into a generalized image.
Why wrong: Capturing a generalized image is for creating reusable templates, not for moving a running VM to fresh infrastructure. It is a much heavier operation than the scenario requires.
- D
Stop/deallocate the VM.
Deallocating the VM releases the current compute placement while preserving the VM resource, disks, and NIC. Starting it later will place it on different infrastructure, which can help clear host-related issues.
- E
Convert the VM to an availability set.
Why wrong: Availability set membership is a deployment design choice, not an operational action that moves an existing VM to a new host. It does not solve the immediate troubleshooting need.
Quick Answer
The answer is to stop/deallocate the VM, which forces the underlying hardware lease to be released, and then to redeploy the VM, which explicitly moves it to a new Azure host node while preserving the VM resource, its disks, and its NIC. When an Azure host is degraded, the key technical concept is that the VM’s compute lease is tied to that faulty physical server; stopping the VM breaks that lease, and redeploying instructs Azure to place the VM onto fresh infrastructure without recreating the resource. On the AZ-104 exam, this scenario tests your understanding of Azure compute lifecycle management versus destructive recovery—a common trap is thinking you need to delete and recreate the VM, which would lose the resource identity. Remember the memory tip: “Stop to drop the lease, redeploy to release the host.”
AZ-104 Deploy and Manage Azure Compute Practice Question
This AZ-104 practice question tests your understanding of deploy and manage azure compute. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
VM-App01 is responding slowly and appears to be on a degraded Azure host. You must keep the VM resource, keep its disks and NIC, and move it to fresh infrastructure before further troubleshooting. Which two actions can achieve that goal? Select two.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Redeploy the VM.
Redeploying the VM (Option A) moves the VM to a new Azure host node while preserving the VM resource, its disks, and NIC. This is the correct action because it resolves host-level degradation without deleting or recreating the VM. Stopping/deallocating the VM (Option D) releases the underlying hardware lease, which forces the VM to be placed on a new host when started again, also preserving the VM resource, disks, and NIC.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse 'Redeploy' with 'Delete and recreate' or think that stopping the VM is insufficient, but in Azure, stop/deallocate is the standard way to force a host migration while keeping the VM resource intact.
Trap categories for this question
Scenario analysis trap
Capturing a generalized image is for creating reusable templates, not for moving a running VM to fresh infrastructure. It is a much heavier operation than the scenario requires.
Detailed technical explanation
How to think about this question
Redeploy (Option A) triggers a platform-level operation that re-provisions the VM on a new compute node while retaining all attached managed disks and NICs; it is equivalent to a 'soft migration' that does not require any image preparation. Stop/deallocate (Option D) releases the VM's lease on the underlying hardware, so when the VM is started again, Azure's placement algorithm selects a healthy host; this is the most common method to recover from host degradation without any data loss. Both actions preserve the VM's resource ID, configuration, and all attached resources.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
