AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 330

You are designing an AWS Direct Connect solution into your VPC. You need to consider requirements for the customer router to terminate the Direct Connect link at the Direct Connect location.
Which three factors that must be supported should you consider when choosing the customer router? (Choose three.)

Answer options

• A. 802.1Q VLAN encapsulation
• B. 802.1ax or 802.3ad link aggregation
• C. OSPF
• D. BGP
• E. single-mode optical fiber connectivity
• F. 1-Gbps copper connectivity

Correct answer: A, D, E

Explanation

AWS Direct Connect requires the customer router to support 802.1Q VLAN encapsulation to partition the physical connection into multiple virtual interfaces. Additionally, it must support Border Gateway Protocol (BGP) for routing and single-mode optical fiber connectivity (1000BASE-LX or 10GBASE-LR) for the physical connection. OSPF and copper connections are not supported for terminating Direct Connect links.
