- A
Azure Backup with a Recovery Services vault.
This provides centralized VM protection, retention policies, and restore capabilities.
- B
Managed disk snapshots only.
Why wrong: Snapshots can help with point-in-time recovery but do not provide the same centralized backup management and retention capabilities.
- C
Azure Site Recovery only.
Why wrong: Site Recovery is focused on replication and disaster recovery rather than standard backup retention management.
- D
Boot diagnostics.
Why wrong: Boot diagnostics helps troubleshoot VM startup problems and does not protect VM data for restore.

AZ-104 Deploy and Manage Azure Compute Practice Question
This AZ-104 practice question tests your understanding of deploy and manage azure compute. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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.
A virtual machine named VM-App01 hosts a critical internal application. You need to protect the VM so that it can be restored if the VM is deleted or corrupted. The solution must provide centralized backup management and retention policies. What should you use?
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
✓
Azure Backup with a Recovery Services vault.
Azure Backup with a Recovery Services vault is the correct choice because it provides centralized backup management, configurable retention policies, and the ability to restore a VM even if it is deleted or corrupted. Unlike snapshots, Azure Backup stores backups in a separate vault, supports application-consistent backups via the Volume Shadow Copy Service (VSS), and offers long-term retention with backup policies.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Azure Backup with a Recovery Services vault.
Why this is correct
This provides centralized VM protection, retention policies, and restore capabilities.
Related concept
Read the scenario before looking for a memorised answer.
- ✗
Managed disk snapshots only.
Why it's wrong here
Snapshots can help with point-in-time recovery but do not provide the same centralized backup management and retention capabilities.
When this WOULD be correct
You need to create a point-in-time backup of a single managed disk (e.g., data disk) for quick restoration or to create a new VM from the snapshot, and centralized backup management or retention policies are not required.
- ✗
Azure Site Recovery only.
Why it's wrong here
Site Recovery is focused on replication and disaster recovery rather than standard backup retention management.
When this WOULD be correct
If the question asked for a solution to replicate VMs to another Azure region for failover during a regional outage, ensuring business continuity with minimal downtime, Azure Site Recovery would be the correct answer.
- ✗
Boot diagnostics.
Why it's wrong here
Boot diagnostics helps troubleshoot VM startup problems and does not protect VM data for restore.
When this WOULD be correct
When the question asks for a method to troubleshoot a VM that fails to boot or to capture boot logs for diagnostic purposes, and the solution does not need to restore the VM from backup.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The AZ-104 exam frequently reuses these exact scenarios with slightly different constraints.
✓Azure Backup with a Recovery Services vault.Correct answer▾
Why this is correct
This provides centralized VM protection, retention policies, and restore capabilities.
✗Managed disk snapshots only.Wrong answer — click to see why▾
Why this is wrong here
Managed disk snapshots only provide crash-consistent backups for individual disks, but they lack centralized management, retention policies, and the ability to restore the entire VM configuration (including network and OS settings) in case of VM deletion or corruption.
★ When this WOULD be the correct answer
You need to create a point-in-time backup of a single managed disk (e.g., data disk) for quick restoration or to create a new VM from the snapshot, and centralized backup management or retention policies are not required.
Why candidates choose this
Candidates may think snapshots are sufficient for VM protection because they can restore disks, but they overlook the need for centralized management, retention policies, and full VM restore capabilities that Azure Backup provides.
✗Azure Site Recovery only.Wrong answer — click to see why▾
Why this is wrong here
Azure Site Recovery is designed for disaster recovery and business continuity by replicating VMs to a secondary region, not for centralized backup management with retention policies for restoring deleted or corrupted VMs.
★ When this WOULD be the correct answer
If the question asked for a solution to replicate VMs to another Azure region for failover during a regional outage, ensuring business continuity with minimal downtime, Azure Site Recovery would be the correct answer.
Why candidates choose this
Candidates may confuse backup (Azure Backup) with disaster recovery (Azure Site Recovery), as both involve protecting VMs, but they serve different purposes: backup for point-in-time restoration, Site Recovery for replication and failover.
✗Boot diagnostics.Wrong answer — click to see why▾
Why this is wrong here
Boot diagnostics only captures serial console output and screenshots for troubleshooting boot failures; it does not provide backup or restore capabilities for VM deletion or corruption.
★ When this WOULD be the correct answer
When the question asks for a method to troubleshoot a VM that fails to boot or to capture boot logs for diagnostic purposes, and the solution does not need to restore the VM from backup.
Why candidates choose this
Candidates may confuse boot diagnostics with a recovery feature because the name implies it helps with VM issues, but it is purely diagnostic and not a backup solution.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse Azure Backup (for backup and retention) with Azure Site Recovery (for disaster recovery), or assume that disk snapshots alone are sufficient for full VM recovery, ignoring the need for centralized management and retention policies.
Detailed technical explanation
How to think about this question
Azure Backup uses the Backup Extension (VMSnapshot or VMSnapshotLinux) to take crash-consistent or application-consistent snapshots, which are then transferred to the Recovery Services vault. The vault provides geo-redundant storage (GRS) by default, ensuring backups survive regional failures, and supports soft delete to protect against accidental deletion of backup data. In a real-world scenario, if VM-App01 is deleted, Azure Backup can restore the entire VM (including disks, network interfaces, and tags) from the latest recovery point, whereas snapshots alone would require manual re-creation of the VM configuration.
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.
