Explanation:
The best option is 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. This is because the failover should be tested in a separate development environment to avoid impacting real data. The force-data-loss mode will simulate a full failover and restart, which is the most accurate test of disaster recovery. Limited-data-loss mode only fails over reads, which does not fully test write capabilities. Initiating the failover in production or increasing replicas risks impacting real production data.

You are managing a Standard Tier Memorystore for Redis instance that is currently deployed in a production environment. Your goal is to test the system's disaster recovery capabilities by simulating a failover scenario. It is crucial that this simulation does not affect your production data in any way. How would you achieve this?
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.
