CV0-004 Practice Question: A cloud administrator is designing a backup…
A cloud administrator is designing a backup strategy for a virtual machine running a critical application. The application stores data on a separate data disk. Which TWO of the following practices should the administrator include to ensure a reliable backup?
⚠ Common exam trap
CV0-004 often tests backup best practices; candidates might choose encryption or hypervisor snapshots as reliability measures, but the key is application consistency and including all necessary components (system state and data disk).
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
✓
Ensure the backup includes the system state and data disk.
Option A is correct because a reliable backup of a VM hosting a critical application must capture both the operating system/system state and the separate data disk, so the VM can be fully restored and the application's data is not lost. Option D is correct because guest-level backups with application-aware processing use VSS (or equivalent) to quiesce the application and flush pending writes, ensuring transactionally consistent backups of the critical application. Option B is a good security practice but is not required for backup reliability, so it is not one of the two best answers. Option C is insufficient because file-level backups of only the data disk omit the system state and may not capture application-consistent data. Option E is incorrect because hypervisor-level snapshots alone are not a complete backup strategy and do not provide application-aware consistency or long-term retention.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Ensure the backup includes the system state and data disk.
Why this is correct
Capturing both the system state and the separate data disk ensures the VM's OS configuration and the application's stored data are recoverable together. Omitting either leaves a gap: a restored VM without its data disk, or data without a bootable, configured system.
- ✗
Encrypt the backup files before storing them off-site.
Why it's wrong here
Encryption protects confidentiality at rest, not backup reliability or recoverability. The stem's requirement is capturing the separate data disk consistently alongside the VM; encryption neither quiesces the application nor includes that disk. It would be the right choice when regulatory or security policy mandates protecting off-site backup media from unauthorised disclosure.
- ✗
Use file-level backups for the data disk only.
Why it's wrong here
File-level backups of only the data disk omit the operating system and application configuration, so a full VM restore is impossible. The scenario requires protecting the whole virtual machine plus its separate data disk. File-level backups are the right choice when only specific documents or datasets need granular recovery.
- ✓
Perform guest-level backups with application-aware processing.
Why this is correct
Guest-level backups with application-aware processing quiesce the application and flush pending writes before snapshotting, ensuring the separate data disk stays transactionally consistent. This satisfies the stem's reliability constraint, which crash-consistent image backups alone cannot guarantee for a running critical application.
- ✗
Rely solely on hypervisor-level snapshots.
Why it's wrong here
Hypervisor snapshots capture the VM's disk state but not application-consistent data, and they are not independent backups; they also omit the separate data disk unless explicitly included. They suit short-term rollback before patching or upgrades, not the reliable, restorable backup the scenario demands.
