A company is designing a disaster recovery solution for a critical application that runs on Amazon EC2 instances in a single AWS Region. The application uses an Amazon RDS for MySQL database. The recovery time objective (RTO) is 1 hour and the recovery point objective (RPO) is 15 minutes. Which combination of steps should the company take to meet these requirements? (Choose THREE.)

Trap 1: Configure a Multi-AZ deployment for the RDS database in the primary…

Multi-AZ is for high availability within a Region, not for cross-Region DR.

Trap 2: Deploy the application on Amazon Aurora Global Database.

Aurora is a different database engine, not RDS MySQL.

Study all Route 53 Failover common traps →

A
Use Amazon Route 53 health checks to monitor the primary application and configure DNS failover to the secondary Region.
Route 53 health checks and failover route traffic to the secondary Region when the primary fails.
B
Configure a Multi-AZ deployment for the RDS database in the primary Region.
Why wrong: Multi-AZ is for high availability within a Region, not for cross-Region DR.
C
Deploy the application on Amazon Aurora Global Database.
Why wrong: Aurora is a different database engine, not RDS MySQL.
D
Create an Amazon Machine Image (AMI) of the EC2 instances and copy it to the secondary Region. Use an Auto Scaling group to launch instances from the AMI.
Copying AMIs to another Region allows recovery of EC2 instances.
E
Create a cross-Region read replica of the RDS MySQL database in the secondary Region.
Cross-Region read replicas provide asynchronous replication with low RPO.

Question 4hardmultiple choice

Read the full DNS explanation →

A company is designing a new application that must be highly available across multiple AWS Regions. The application will run on EC2 instances behind an Application Load Balancer. The company needs a DNS-based routing policy that routes users to the nearest healthy endpoint based on latency. Which Amazon Route 53 routing policy should be used?

Trap 1: Failover routing policy

Failover routing policy is used for active-passive failover, not for latency-based routing.

Trap 2: Weighted routing policy

Weighted routing policy distributes traffic based on assigned weights, not on latency to the user.

Trap 3: Simple routing policy

Simple routing policy routes traffic to a single resource; it does not consider latency or health.

Question 7hardmultiple choice

Review the full routing breakdown →

A company is designing a multi-region active-active application using Amazon Route 53 latency-based routing. The application runs on Amazon EC2 instances behind Application Load Balancers (ALBs) in two AWS Regions. The company needs to ensure that if one region becomes unavailable, traffic is automatically routed to the healthy region with minimal disruption. Which configuration meets these requirements?

Trap 1: Use Route 53 failover routing instead of latency-based routing.

Failover routing is for active-passive, not active-active.

Trap 2: Configure Route 53 latency-based routing without health checks.

Without health checks, Route 53 will still send traffic to unhealthy endpoints.

Trap 3: Use Route 53 weighted routing with weights set to 50 for each…

Weighted routing does not automatically failover based on health.
