AWS Certified Solutions Architect – Professional — Question 28

An organization is setting up an application on AWS to have both High Availability (HA) and Disaster Recovery (DR). The organization wants to have both
Recovery point objective (RPO) and Recovery time objective (RTO) of 10 minutes.
Which of the below mentioned service configurations does not help the organization achieve the said RPO and RTO?

Answer options

• A. Take a snapshot of the data every 10 minutes and copy it to the other region.
• B. Use an elastic IP to assign to a running instance and use Route 53 to map the user's domain with that IP.
• C. Create ELB with multi-region routing to allow automated failover when required.
• D. Use an AMI copy to keep the AMI available in other regions.

Correct answer: C

Explanation

Option C is the correct answer because creating an ELB with multi-region routing does not inherently provide a way to meet the 10-minute RPO and RTO, as it mainly focuses on load balancing and does not guarantee data recovery or minimize downtime. Options A, B, and D all involve strategies that directly contribute to maintaining data availability and quick recovery times.
