Google Cloud Professional Data Engineer — Question 140

You have a Standard Tier Memorystore for Redis instance deployed in a production environment. You need to simulate a Redis instance failover in the most accurate disaster recovery situation, and ensure that the failover has no impact on production data. What should you do?

Answer options

• A. Create a Standard Tier Memorystore for Redis instance in the development environment. Initiate a manual failover by using the limited-data-loss data protection mode.
• B. Create a Standard Tier Memorystore for Redis instance in a development environment. Initiate a manual failover by using the force-data-loss data protection mode.
• C. Increase one replica to Redis instance in production environment. Initiate a manual failover by using the force-data-loss data protection mode.
• D. Initiate a manual failover by using the limited-data-loss data protection mode to the Memorystore for Redis instance in the production environment.

Correct answer: B

Explanation

The correct answer is B because initiating a manual failover using the force-data-loss data protection mode in a development environment allows for accurate simulation without impacting production data. Options A and D use limited-data-loss mode, which does not align with the goal of simulating a complete failover. Option C suggests modifying the production instance, which is not suitable for a simulation scenario.
