Google Associate Cloud Engineer Question 85
Select 3Google Cloud PlatformYou are designing a multi-region web application on Google Cloud that requires high availability and disaster recovery. Which of the following resource location strategies should you implement to ensure the application remains resilient to regional failures?
- A
Deploy the application's resources in multiple zones within a single region.
- B
Deploy the application's resources across multiple regions.
- C
Use a global load balancer to distribute traffic across instances in different regions.
- D
Deploy a backup of the application in a different region with a manual failover plan.
- E
Use regional persistent disks for data storage to ensure data availability across regions.
Show answer and explanation
Correct answers: B, C, D
Explanation
To achieve high availability and disaster recovery, it's important to deploy resources across multiple regions, use a global load balancer to manage traffic distribution, and have a robust backup and failover strategy. Options 2, 3, and 4 collectively ensure that the application remains available and can recover from regional failures effectively.
- A. Incorrect.
Deploying resources in multiple zones within a single region provides zone-level redundancy but does not protect against regional failures.
- B. Correct.
Deploying resources across multiple regions ensures that if one region fails, the application can still operate from another region, providing high availability and disaster recovery.
- C. Correct.
A global load balancer can redirect traffic to healthy instances in different regions, ensuring availability even if one region goes down.
- D. Correct.
Having a backup in a different region with a manual failover plan can aid in disaster recovery by switching operations to the backup region.
- E. Incorrect.
Regional persistent disks only provide redundancy within a single region and do not help in case of a regional failure.
