ExamKiller has three separate departments and each department has their own AWS accounts.
The HR department has created a file sharing site where all the on roll employees’ data is
uploaded. The Admin department uploads data about the employee presence in the office to their
DB hosted in the VPC. The Finance department needs to access data from the HR department to
know the on roll employees to calculate the salary based on the number of days that an
employee is present in the office.
How can ExamKiller setup this scenario?
A.
It is not possible to configure VPC peering since each department has a separate AWS account.
B.
Setup VPC peering for the VPCs of Admin and Finance.
C.
Setup VPC peering for the VPCs of Finance and HR as well as between the VPCs of Finance and
Admin.
D.
Setup VPC peering for the VPCs of Admin and HR
Explanation:
A Virtual Private Cloud (VPC) is a virtual network dedicated to the user’s AWS account. It enables
the user to launch AWS resources into a virtual network that the user has defined. A VPC peering
connection allows the user to route traffic between the peer VPCs using private IP addresses as if
they are a part of the same network. This is helpful when one VPC from the same or different
AWS account wants to connect with resources of the other VPC.
