Question

A company needs to run a critical application on AWS. The company needs to use Amazon EC2 for the application’s database. The database must be highly available and must fail over automatically if a disruptive event occurs. Which solution will meet these requirements?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Launch two EC2 instances, each in a different Availability Zone in the same AWS Region. Install the database on both EC2 instances. Configure the EC2 instances as a cluster. Set up database replication. Amazon EC2 provides resizable virtual servers when you need full control of the operating system. 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.
