AWS Certified Advanced Networking – Specialty (ANS-C00) — Question 218

Your company has a DX connection and you just added a new VPC and Private VIF to which you have connected to your DX link. You copied the settings from the other VPC to ensure it's the same. Once you connected the new VIF, you began seeing problems with connectivity to both VPCs.
You checked to make sure you didn't use the same CIDR with each VPC, so what could be the problem?

Answer options

• A. You used the same VLAN ID for both connections.
• B. You overloaded your DX circuit.
• C. Your MPLS provider does not allow traffic to two VPCs.
• D. You can only connect one VIF to a DX circuit.

Correct answer: A

Explanation

The correct answer is A because using the same VLAN ID for both connections can lead to conflicts and connectivity issues. Options B, C, and D are incorrect as they do not directly pertain to the configuration of the VIFs and VLAN IDs in the context of multiple VPCs connected to a Direct Connect link.
