Question 214

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?

  • 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.

"no impact on production data" Thus, the best practice is about simulating in a different environment. force-data-loss mode covers the most accurate disaster recovery situation.
