AWS Certified Solutions Architect - Associate SAA-C03 — Topic 1 Question 466

Question

A company designed a stateless two-tier application that uses Amazon EC2 in a single Availability Zone and an Amazon RDS Multi-AZ DB instance. New company management wants to ensure the application is highly available. What should a solutions architect do to meet this requirement?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Configure the application to use Multi-AZ EC2 Auto Scaling and create an Application Load Balancer 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. An Application Load Balancer distributes HTTP/HTTPS traffic and supports path/host routing. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
