AWS Certified SysOps Administrator – Associate (legacy) — Question 118

A user is using the AWS EC2. The user wants to make so that when there is an issue in the EC2 server, such as instance status failed, it should start a new instance in the user's private cloud. Which AWS service helps to achieve this automation?

Answer options

• A. AWS CloudWatch + Cloudformation
• B. AWS CloudWatch + AWS AutoScaling + AWS ELB
• C. AWS CloudWatch + AWS VPC
• D. AWS CloudWatch + AWS SNS

Correct answer: D

Explanation

The correct answer is D, AWS CloudWatch + AWS SNS, as AWS CloudWatch can monitor the instance status and trigger an AWS SNS notification, which can initiate the process to launch a new instance. The other options involve services that do not directly address the requirement for automation in response to instance failures in the specified context.
