AZ-104 Question 266
Single answerYou are an Azure Administrator for an e-commerce company that hosts a critical application on an Azure VM named 'AppVM'. The VM is backed up daily to a Recovery Services vault using an existing backup policy that retains data for 14 days. Due to new compliance requirements, backups must now be retained for 60 days. You need to update your backup strategy so that new backups meet this requirement with minimal administrative overhead. Which approach should you take first?
- A
Modify the existing backup policy to set the daily retention to 60 days
- B
Create a new backup policy in the same vault that sets the daily retention to 60 days, then apply it to the VM
- C
Turn off the backup for 'AppVM', then re-enable backup with a new policy specifying 60-day retention
- D
Create a new Recovery Services vault and define a 60-day retention policy, then back up the VM to this new vault
Show answer and explanation
Correct answer: A
Explanation
With Azure Backup, adjusting the retention period of an existing policy is straightforward. This approach modifies future backups to meet the new compliance requirement while minimizing disruption and administrative effort.
- A. Correct.
Modifying the existing policy is the most straightforward and efficient way to meet the new 60-day retention requirement. Future backups will be retained for 60 days without significant additional administrative overhead.
- B. Incorrect.
Creating a new backup policy is possible, but it requires additional steps to apply it to the VM and may be more work than simply updating the existing policy.
- C. Incorrect.
Turning off the backup and re-enabling it disrupts the existing backup chain and could lead to data protection gaps, which is not advisable for a critical production workload.
- D. Incorrect.
Creating a new Recovery Services vault is a more complex approach than necessary and does not provide any additional benefit over updating the existing policy.
