Exhibit
Command output: - Azure portal shows: DataDisk01 size = 512 GiB - Inside the guest OS, the partition still shows 256 GiB used and 256 GiB unallocated - The application cannot write to the extra space yet
Based on the exhibit, what should the administrator do next so the VM can use the extra capacity on the resized data disk?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
Resize the managed disk again in Azure.
The managed disk is already larger in Azure, so resizing it again is not the missing step.
B
Best answer
Extend the partition or file system inside the VM.
After Azure increases a managed disk, the guest operating system still needs to recognize the new space. Expanding the partition or file system inside the VM makes the newly allocated disk capacity available to applications.
C
Distractor review
Detach the disk and attach it to another VM.
Moving the disk does not solve the current VM's need to use the additional space.
D
Distractor review
Create a new virtual machine from the disk.
Recreating the VM is unnecessary because the disk was already expanded successfully.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

FAQ
Questions learners often ask
What does this AZ-104 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Extend the partition or file system inside the VM. — When Azure shows the managed disk has been resized but the guest OS still has unallocated space, the next step is to expand the partition or file system inside the VM. Azure changes the virtual disk size, but the operating system must be told to use that extra capacity. This is a common post-resize task for both Windows and Linux VMs and is the quickest way to make the new storage usable. Why others are wrong: The disk is already resized in Azure, so repeating the resize is unnecessary. Detaching the disk or rebuilding the VM adds disruption without addressing the missing guest-level partition expansion. The problem is not the disk itself but the file system inside the guest OS.
