ANS-C01 Question 205
Select 3Your organization has deployed an SD-WAN solution and wants to integrate it with AWS for optimized traffic management and hybrid connectivity. You decide to use AWS Transit Gateway Connect. Which of the following steps are required to enable this setup?
- A
Establish a Connect peer using a GRE tunnel between the Transit Gateway and your SD-WAN appliance.
- B
Attach the SD-WAN appliance directly to the Transit Gateway using a VPC attachment.
- C
Configure the Transit Gateway Connect attachment by associating it with an existing Transit Gateway attachment.
- D
Set up dynamic routing using Border Gateway Protocol (BGP) between the Connect peer and the Transit Gateway.
- E
Manually configure static routes on the Transit Gateway to handle traffic from the SD-WAN appliance.
Show answer and explanation
Correct answers: A, C, D
Explanation
AWS Transit Gateway Connect is specifically designed to integrate SD-WAN appliances with AWS. The integration requires creating a Connect attachment, establishing a GRE-based Connect peer, and configuring BGP for dynamic routing. Direct attachment of SD-WAN appliances or reliance solely on static routes doesn't align with the capabilities or best practices of Transit Gateway Connect.
- A. Correct.
Correct. Establishing a Connect peer using a GRE tunnel is a key step in configuring Transit Gateway Connect to integrate with SD-WAN appliances.
- B. Incorrect.
Incorrect. SD-WAN appliances cannot be directly attached to a Transit Gateway. Instead, a Connect attachment is used for such integrations.
- C. Correct.
Correct. A Transit Gateway Connect attachment must be associated with an existing Transit Gateway attachment, such as a VPC or VPN attachment, to enable traffic flow.
- D. Correct.
Correct. BGP is used for dynamic routing between the Transit Gateway and the SD-WAN appliance, allowing efficient route advertisement and traffic management.
- E. Incorrect.
Incorrect. While static routes can be used in some cases, dynamic routing using BGP is the recommended and scalable approach for Transit Gateway Connect setups.
