Google Associate Cloud Engineer Question 181
Select 2Google Cloud PlatformYou are tasked with creating a backup strategy for a critical application running on a Compute Engine virtual machine in Google Cloud Platform. The application data is stored on a persistent disk. You need to ensure that you can quickly restore the application to a previous state in case of data corruption or accidental deletion. Which of the following steps should you include in your strategy?
- A
Create a snapshot of the persistent disk at regular intervals.
- B
Schedule an automatic snapshot deletion after 30 days.
- C
Use the snapshots to create a new disk when restoration is needed.
- D
Store snapshots in a different region to ensure availability.
Show answer and explanation
Correct answers: A, C
Explanation
Regular snapshots provide multiple restore points, ensuring that you can revert to a previous state if needed. Using these snapshots to create new disks allows for rapid restoration. Automatic deletion of snapshots may interfere with recovery objectives if older data is needed, and while cross-region storage enhances availability, the primary focus here is on the quick restoration using snapshots within the same region.
- A. Correct.
Creating regular snapshots ensures that you have multiple restore points, which is essential for quick recovery.
- B. Incorrect.
Automatically deleting snapshots may not align with the recovery point objectives, as older snapshots might be needed for certain restorations.
- C. Correct.
Snapshots can be used to create new disks, making it possible to restore the application to its previous state quickly.
- D. Incorrect.
While storing snapshots in a different region can enhance availability, it is not necessary for a basic backup strategy focused on restoration within the same region.
