AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 11

You have to set up an AWS Direct Connect connection to connect your on-premises to an AWS VPC. Due to budget requirements, you can only provision a single
Direct Connect port. You have two border gateway routers at your on-premises data center that can peer with the Direct Connect routers for redundancy.
Which two design methodologies, in combination, will achieve this connectivity? (Choose two.)

Answer options

• A. Terminate the Direct Connect circuit on a L2 border switch, which in turn has trunk connections to the two routers.
• B. Create two Direct Connect private VIFs for the same VPC, each with a different peer IP.
• C. Terminate the Direct Connect circuit on any of the one routers, which in turn will have an IBGP session with the other router.
• D. Create one Direct Connect private VIF for the VPC with two customer peer IPs.
• E. Provision two VGWs for the VPC and create one Direct Connect private VIF per VGW.

Correct answer: A, B

Explanation

Option A is correct because terminating the Direct Connect circuit on a Layer 2 border switch allows for redundancy through the trunk connections to both routers. Option B is also correct as it provides multiple private VIFs, ensuring redundancy and load balancing for the VPC. Options C, D, and E do not fulfill the requirement of maintaining redundancy or utilize the Direct Connect port effectively given the budget constraints.
