AWS Certified SysOps Administrator SOA-C01 – Question323

An application you maintain consists of multiple EC2 instances in a default tenancy VPC. This application has undergone an internal audit and has been determined to require dedicated hardware for one instance. Your compliance team has given you a week to move this instance to single-tenant hardware. Which process will have minimal impact on your application while complying with this requirement?

A.
Create a new VPC with tenancy=dedicated and migrate to the new VPC
B. Use ec2-reboot-instances command line and set the parameter "dedicated=true"
C. Right click on the instance, select properties and check the box for dedicated tenancy
D. Stop the instance, create an AMI, launch a new instance with tenancy=dedicated, and terminate the old instance

Correct Answer: D

Explanation:

Explanation: You cannot change the tenancy of a default instance after you’ve launched it. You can change the tenancy of an instance from “dedicated” to “host” after you’ve launched it, and vice versa.
