Elastic Load Balancer (ELB) configured to use the public subnets. The application s web tier leverages the ELB. Auto Scaling and a mum-AZ RDS database instance The organization would like to eliminate any potential single points ft failure in this design.
What step should you take to achieve this organization's objective?

Answer options

• A. Nothing, there are no single points of failure in this architecture.
• B. Create and attach a second IGW to provide redundant internet connectivity.
• C. Create and configure a second Elastic Load Balancer to provide a redundant load balancer.
• D. Create a second multi-AZ RDS instance in another Availability Zone and configure replication to provide a redundant database.

Correct answer: A

Explanation

The correct answer is A because the architecture already incorporates redundancy through the use of multiple Availability Zones for the RDS instance and the ELB. The other options suggest adding redundancy where it is unnecessary, as the current setup is designed to mitigate single points of failure effectively.
