AWS Certified Solutions Architect - Associate SAA-C03 — Topic 1 Question 581

Question

A company runs a stateful production application on Amazon EC2 instances. The application requires at least two EC2 instances to always be running. A solutions architect needs to design a highly available and fault-tolerant architecture for the application. The solutions architect creates an Auto Scaling group of EC2 instances. Which set of additional steps should the solutions architect take to meet these requirements?

Accepted Answer

Correct answer: B. The correct answer is B. Option B: Set the Auto Scaling group's minimum capacity to four. Deploy two On-Demand Instances in one Availability Zone and two On-Demand Instances in a second Availability Zone. Auto Scaling adjusts capacity automatically to match demand, improving availability and cost efficiency. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
