• D. Immediately after submitting your request for AWS Direct Connect Connection

Correct answer: B

Explanation

To complete the physical cross-connect at the AWS Direct Connect location, you or your network provider must present the Letter of Authorization and Connecting Facility Assignment (LOA-CFA) issued by AWS. This document authorizes the colocation provider to run the physical fiber patch cable to AWS's equipment. Other steps, such as configuring virtual interfaces, can only occur after this physical connection is successfully established.
