ANS-C01 Question 343
Select 3You are designing a hybrid network between your on-premises data center and AWS using AWS Direct Connect. Your on-premises router supports BGP, and you want to enable dynamic routing for failover and route advertisement. Which of the following actions are required to configure BGP over Direct Connect?
- A
Configure a private virtual interface (VIF) in the AWS Direct Connect console.
- B
Establish a BGP session between your on-premises router and the AWS Direct Connect router.
- C
Manually configure static routes to AWS services in your on-premises router.
- D
Use a public virtual interface (VIF) to advertise private IP prefixes to AWS.
- E
Ensure you have an ASN (Autonomous System Number) for your on-premises network.
Show answer and explanation
Correct answers: A, B, E
Explanation
To configure BGP over Direct Connect for a hybrid network, you need to create a private virtual interface (VIF), establish a BGP session with AWS, and have an Autonomous System Number (ASN) to identify your network. BGP enables dynamic routing for route advertisement and failover, eliminating the need for static routes. Public virtual interfaces are not used for private IP connectivity.
- A. Correct.
Correct. A private virtual interface (VIF) is required for private connectivity between your on-premises network and AWS resources when using Direct Connect.
- B. Correct.
Correct. BGP sessions are necessary to enable dynamic routing, allowing automatic route advertisement and failover.
- C. Incorrect.
Incorrect. Static routes are not required when using BGP, as BGP handles dynamic route advertisement.
- D. Incorrect.
Incorrect. A public virtual interface is used for accessing public AWS services, not for private IP prefixes.
- E. Correct.
Correct. An ASN is necessary for establishing the BGP session with AWS, as it identifies your on-premises network in the BGP configuration.
