AZ-104 Monitor and Maintain Azure Resources Practice Question
This AZ-104 practice question tests your understanding of monitor and maintain azure resources. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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.
Based on the exhibit, the VM backup item was accidentally deleted from the vault yesterday, but the VM itself still exists. What should you do to resume protection with the existing backup item?
Delete the VM and recreate it so the backup can start again.
Why wrong: Deleting and recreating the VM is unnecessary and disruptive. The backup item still exists in soft-deleted state and can be recovered without rebuilding the server.
B
Recover or undelete the backup item from the vault before the soft-delete retention expires.
Because soft delete is enabled and the retention window is still open, the deleted backup item can be recovered from the Recovery Services vault. Undeleting the item restores the backup relationship without requiring a new protection configuration or a rebuild of the VM.
C
Create a new action group so the vault can re-enable protection.
Why wrong: Action groups are for Azure Monitor notifications, not for Azure Backup protection state. They do not restore deleted backup items.
D
Disable diagnostic settings on the vault and then re-enable them.
Why wrong: Diagnostic settings affect monitoring data flow, not backup item lifecycle. They cannot bring a deleted backup item back into protected state.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Recover or undelete the backup item from the vault before the soft-delete retention expires.
Azure Backup uses soft-delete for backup items, which retains deleted backup data for 14 days by default. Since the backup item was accidentally deleted yesterday, it is still in the soft-delete state and can be recovered or undeleted from the vault before the retention period expires. Once recovered, protection can be resumed on the existing VM without data loss or reconfiguration.
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 may think deleting a backup item permanently removes all data, but Azure Backup's soft-delete feature retains the data for 14 days, allowing recovery without recreating the VM or backup configuration.
Detailed technical explanation
How to think about this question
Soft-delete in Azure Backup is enabled by default at the vault level and retains backup data for a configurable retention period (14 days minimum). During this period, the backup item is in a 'soft-deleted' state and can be undeleted via the Azure portal, PowerShell, or CLI using the `Enable-AzRecoveryServicesBackupProtection` cmdlet with the `-RecoveryPoint` parameter. If the soft-delete retention expires, the backup data is permanently purged and cannot be recovered, requiring a fresh backup configuration.

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

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.
