AWS Certified Solutions Architect – Professional — Question 270

AWS has launched T2 instances which come with CPU usage credit. An organization has a requirement which keeps an instance running for 24 hours. However, the organization has high usage only during 11 AM to 12 PM. The organization is planning to use a T2 small instance for this purpose.
If the organization already has multiple instances running since Jan 2012, which of the below mentioned options should the organization implement while launching a T2 instance?

Answer options

• A. The organization must migrate to the EC2-VPC platform first before launching a T2 instance.
• B. While launching a T2 instance the organization must create a new AWS account as this account does not have the EC2-VPC platform.
• C. Create a VPC and launch a T2 instance as part of one of the subnets of that VPC.
• D. While launching a T2 instance the organization must select EC2-VPC as the platform.

Correct answer: C

Explanation

T2 instances require a Virtual Private Cloud (VPC) and cannot be launched on the legacy EC2-Classic platform. Because this AWS account was created before December 2013 (in January 2012), it supports EC2-Classic and might not have a default VPC. Consequently, the organization must manually create a VPC and launch the T2 instance inside one of its subnets.
