ANS-C01 Question 346
Select 3You are setting up a hybrid network using AWS Direct Connect and need to establish dynamic routing between your on-premises data center and your VPC. Which of the following steps are required to configure Border Gateway Protocol (BGP) over AWS Direct Connect?
- A
Configure a Virtual Private Gateway (VGW) in the VPC and associate it with the Direct Connect connection.
- B
Set up a private Autonomous System Number (ASN) for your on-premises router and configure it to peer with AWS.
- C
Enable VPC peering between your on-premises data center and the VPC.
- D
Configure a Customer Gateway (CGW) with your on-premises router's public IP address.
- E
Establish a BGP session between the on-premises router and the AWS Direct Connect router.
Show answer and explanation
Correct answers: A, B, E
Explanation
To configure BGP over AWS Direct Connect for a hybrid network, you need to set up a Virtual Private Gateway (VGW) to connect your VPC, configure a private ASN for your on-premises router, and establish a BGP session for dynamic routing. VPC peering and Customer Gateway are unrelated to this scenario, as they are used for different networking setups.
- A. Correct.
Correct. The Virtual Private Gateway (VGW) is required to connect the VPC to the Direct Connect connection, enabling the hybrid network.
- B. Correct.
Correct. A private ASN is necessary for BGP configuration to establish dynamic routing between your on-premises router and AWS.
- C. Incorrect.
Incorrect. VPC peering is used for connecting multiple VPCs, not for hybrid network setups using AWS Direct Connect.
- D. Incorrect.
Incorrect. A Customer Gateway (CGW) is used for VPN connections, not for Direct Connect configurations.
- E. Correct.
Correct. Establishing a BGP session is essential for dynamic routing over AWS Direct Connect.
