Topic 1 Question 257
A company's SysOps administrator maintains a highly available environment. The environment includes Amazon EC2 instances and an Amazon RDS Multi-AZ database. The EC2 instances are in an Auto Scaling group behind an Application Load Balancer.
Recently, the company conducted a failover test. The SysOps administrator needs to decrease the failover time of the RDS database by at least 10%.
Which solution will meet this requirement?
Increase the RDS instance size.
Modify the RDS cluster to run in a single Availability Zone.
Create a read replica in another AWS Region. Promote the read replica in case of failure.
Create an RDS proxy. Point the application to the proxy endpoint.
