AWS Certified Solutions Architect - Associate SAA-C03 — Topic 1 Question 757

Question

A company is running a legacy system on an Amazon EC2 instance. The application code cannot be modified, and the system cannot run on more than one instance. A solutions architect must design a resilient solution that can improve the recovery time for the system. What should the solutions architect recommend to meet these requirements?

Accepted Answer

Correct answer: D. The correct answer is D. Option D: Launch the EC2 instance with two Amazon Elastic Block Store (Amazon EBS) volumes that use RAID configurations for storage redundancy. Amazon EC2 provides resizable virtual servers when you need full control of the operating system. Amazon EBS provides block storage attached to a single EC2 instance. AWS Config tracks resource configuration changes and evaluates compliance. By spanning multiple Availability Zones / adding redundancy, this option provides the high availability and resilience required.
