A developer wants to keep application data separate from the operating system so the VM can be rebuilt without losing files. Before making a risky change, the administrator also wants a fast rollback point for that data disk. Which two actions should the administrator take? Select two.

Use an ephemeral OS disk for the application files

Ephemeral disks are temporary and are not meant for important data.

Keep the files only on the OS disk and rely on reimaging

Putting data on the OS disk makes recovery and rebuilds riskier.

Delete and recreate the VM from the same image

Recreating the VM does not preserve the current data disk state.

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: Store the application data on a separate managed data disk — Placing the application files on a separate managed data disk keeps them independent from the operating system disk, which means the VM can be rebuilt or reimaged without automatically losing those files. Taking a snapshot of that data disk gives the administrator a fast rollback point before a risky change. Together, these actions support both isolation and quick recovery at the disk level. Why others are wrong: An ephemeral OS disk is temporary by design and should not hold business data. Keeping files only on the OS disk makes rebuilds and reimaging much riskier. Recreating the VM from the same image does not preserve current data changes, so it is not a good rollback strategy for the disk contents.
