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?
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.
Explanation:
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user’s AWS account. The user
can create subnets as per the requirement within a VPC. The AWS account provides twoplatforms:
EC2-CLASSIC and EC2-VPC, depending on when the user has created his AWS account and
which regions he is using. If the user has created the AWS account after 2013-12-04, it supports
only EC2-VPC. In this scenario, since the account is before the required date the supported
platform will be EC2-CLASSIC. It is required that the organization creates a VPC as the T2
instances can be launched only as a part of VPC.
