Topic #: 1
[All AWS Certified Advanced Networking - Specialty ANS-C01 Questions]

A company's AWS environment has two VPCs. VPC A has a CIDR block of 192.168.0.0/16. VPC B has a CIDR block of 10.0.0.0/16. Each VPC is deployed in a separate AWS Region. The company has remote users who work outside the company's offices. These users need to connect to an application that is running in the VPCs.

Traffic to and from the VPCs over the internet must be encrypted. A network engineer must set up connectivity between the remote users and the VPCs.

Which combination of steps should the network engineer take to meet these requirements with the LEAST management overhead? (Choose three.)

  • A. Establish an AWS Site-to-Site VPN connection between VPC A and VPC B.
  • B. Establish a VPC peering connection between VPC A and VPC B.
  • C. Create an AWS Client VPN endpoint in VPC A and VPC B Add an authorization rule to grant access to VPC A and VPC B.
  • D. Create an AWS Client VPN endpoint in VPC A Add an authorization rule to grant access to VPC A and VPC B.
  • E. Add a route to the AWS Client VPN endpoint’s route table to direct traffic to VPC B.
  • F. Add a route to the AWS Client VPN endpoint's route table to direct traffic to VPC A.

BDE, i was doubting but here's what I found. Quote: "The procedure for allowing access to a peered VPC outlined below, is only required if the Client VPN endpoint was configured for split-tunnel mode. In full-tunnel mode, access to the peered VPC is allowed by default." https://docs.aws.amazon.com/vpn/latest/clientvpn-admin/scenario-peered.html

Selected Answer: ADE
B is out as the VPCs are in different regions so I think ADE : one endpoint in VPC A + Site to Site VPN for VPCA to VPCB + add the VPCB route (as to my understanding the VPCA route is there by default as the client is connecting to VPCA)

C) This step involves setting up AWS Client VPN endpoints in both VPC A and VPC B to allow remote users to connect securely. Adding an authorization rule will control access to both VPCs. E) By adding a route in the AWS Client VPN endpoint's route table, the traffic from remote users can be directed to the resources in VPC B. F) Similarly, adding a route for VPC A ensures that traffic from remote users can reach the resources in VPC A.

BDE. Create VPN endpoint in VPC A -> peer with VPC B -> hence clients will be able to connect to VPC B, via VPC A. Client -> VPC A -> VPC B

Selected Answer: CEF
Inter-region VPC peering is only available in certain AWS regions. Therefore, B is evidently wrong as the question didn't mention the specific region names. You will need to create two VPN connections. https://aws.amazon.com/about-aws/whats-new/2017/11/announcing-support-for-inter-region-vpc-peering/

Sorry my bad. Inter-region peering is now fully supported on AWS. So BDE is correct. https://docs.aws.amazon.com/vpc/latest/peering/what-is-vpc-peering.html

VPN peering will not work here as both VPC are in different region.
