Google Associate Cloud Engineer Question 184
Select 2Google Cloud PlatformYou are an Associate Cloud Engineer managing a project that involves multiple Compute Engine instances. Your team requires a fast recovery mechanism in case of data loss. You decide to implement snapshots. Which of the following steps should you take to ensure that your snapshots are efficient and cost-effective?
- A
A. Use regional persistent disks to create snapshots.
- B
B. Schedule snapshots during off-peak hours.
- C
C. Enable automatic snapshot deletion after a specified retention period.
- D
D. Create snapshots of disks attached to stopped instances only.
- E
E. Store snapshots in multi-regional locations for redundancy.
Show answer and explanation
Correct answers: B, C
Explanation
To ensure snapshots are both efficient and cost-effective, it is crucial to manage when they are taken and how long they are retained. Scheduling snapshots during off-peak hours helps optimize resource usage and minimize costs. Additionally, implementing automatic deletion policies ensures that storage costs are kept under control by removing outdated snapshots. These strategies collectively contribute to an efficient snapshot management process.
- A. Incorrect.
Regional persistent disks are not necessary for creating cost-effective snapshots. Snapshots are independent of the type of persistent disk.
- B. Correct.
Scheduling snapshots during off-peak hours can save costs associated with disk operations and reduce resource contention.
- C. Correct.
Enabling automatic snapshot deletion helps manage costs by ensuring that old snapshots are removed after their useful life.
- D. Incorrect.
Snapshots can be created for disks of both running and stopped instances. The instance state does not impact snapshot efficiency.
- E. Incorrect.
While storing snapshots in multi-regional locations provides redundancy, it is not directly related to cost-effectiveness as it incurs additional costs.
