AWS Certified Solutions Architect - Associate SAA-C03 — Topic 1 Question 935

Question

A software company needs to upgrade a critical web application. The application currently runs on a single Amazon EC2 instance that the company hosts in a public subnet. The EC2 instance runs a MySQL database. The application's DNS records are published in an Amazon Route 53 zone. A solutions architect must reconfigure the application to be scalable and highly available. The solutions architect must also reduce MySQL read latency. Which combination of solutions will meet these requirements? (Choose two.)

Accepted Answer

Correct answer: B, C. The correct answer is B, C. Option B: Create and configure an Auto Scaling group to launch private EC2 instances in multiple Availability Zones. Add the instances to a target group behind a new Application Load Balancer. Option C: Migrate the database to an Amazon Aurora MySQL cluster. Create the primary DB instance and reader DB instance in separate Availability Zones. Auto Scaling adjusts capacity automatically to match demand, improving availability and cost efficiency. Amazon EC2 provides resizable virtual servers when you need full control of the operating system. Amazon Aurora is a high-performance managed relational database with built-in replication and failover. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
