A Startup company has primary Web servers hosted on an EC2 instance within a VPC. Backup servers are deployed in a company-owned Data Centre. Data replication occurs between Primary & backup servers every twelve hours & completes in less than 20 mins. For connectivity between VPC & Data Centre, an AWS VPN connection is used. They incurred a huge bill for a VPN connection. The accounts manager of this company is concerned about the VPN billing which is high although used for less than 1 hour daily. Which of the following statement will you, as an AWS consultant, choose to clarify charges to the Accounts Manager? (Select Two.)

Answer options:

A.Charges are based upon the number of connections hours VPN is available.
B. Billing includes charges for Data Transfer IN from Datacenter to AWS over the Internet.
C.Billing includes data transfer charges for data transferred in both directions between AWS VPC & Data Centre over the Internet.
D.Charges are based upon number of connections hours VPN is active & in use.
E.Billing includes charges for Data Transfer OUT from AWS to Datacenter over the Internet.

Correct Answer – A, E
For AWS VPN, there are two charges involved,
1)VPN Connection Hours – Number of hours a VPN connection is in an available state. It is not billed on hours when the VPN connection is active.
2) Data Transfer Charges – Data Centre is using the Internet to establish VPN connectivity to VGW. So, it will be billed at Internet Out charges for Data Transfer from AWSto Datacenter. All Data transfer in AWS from the Datacenter is free.
Option B is incorrect as Data Transfer Charges are billed only for data out of AWS & Data Transfer into AWS is free.
Option C is incorrect as Charges are for data transfer in the outbound direction from AWS & not for both directions.
Option D is incorrect as VPN connection hours will be hours when VPN connection is available & not when it`s actively transferring data.
