Topic 1 Question 25
During a high traffic portion of the day, one of your relational databases crashes, but the replica is never promoted to a master. You want to avoid this in the future. What should you do?
Use a different database
Choose larger instances for your database
Create snapshots of your database more regularly
Implement routinely scheduled failovers of your databases

Answer is D
👍 88Narigdo2019/11/26@chiar, I agree the question i s not clear. In GCP larger instances have larger number of CPUs, Memory and come with their own private network. So increases the instance size would help prevent the need for failover during high traffic times. However, routinely scheduled failovers would allow the team to test the failover when it is not requried. This would make sure it is working when it is required.

Option B may help improve performance, but it won't necessarily prevent a crash or ensure that a replica is promoted to a master in the event of a failure. Option D looks good.
