ANS-C01 Question 196
Select 4Your organization needs a high-bandwidth, low-latency dedicated connection between your on-premises data center and your AWS environment. To achieve this, you decide to set up AWS Direct Connect. During the setup process, you are required to work with a colocation facility and an AWS Partner Network provider to complete the physical connection. Which of the following steps and artifacts are necessary to successfully establish this Direct Connect connection?
- A
Obtain a Letter of Authorization (LOA) from AWS and provide it to the colocation facility.
- B
Procure and install a virtual private gateway (VGW) in your on-premises environment for Direct Connect.
- C
Work with a colocation provider to establish a cross-connect to the AWS Direct Connect endpoint.
- D
Contact an AWS Partner Network (APN) provider to provision a dedicated leased line from your on-premises environment to the colocation facility.
- E
Configure a Border Gateway Protocol (BGP) session between your on-premises router and the Direct Connect router.
Show answer and explanation
Correct answers: A, C, D, E
Explanation
To set up AWS Direct Connect, you need to establish a physical layer connection and configure routing. This involves obtaining an LOA from AWS to authorize the colocation facility to establish the cross-connect, setting up a connection to the colocation facility (often with the help of an APN provider), and configuring BGP for routing. Virtual private gateways are not part of the physical layer setup for Direct Connect.
- A. Correct.
Correct: AWS provides a Letter of Authorization (LOA) when you request a Direct Connect connection. This document is necessary to grant permission to the colocation facility to connect your cross-connect to the AWS Direct Connect endpoint.
- B. Incorrect.
Incorrect: Virtual private gateways (VGWs) are used for Virtual Private Network (VPN) connections and integrating with VPCs, not for establishing the physical layer connection with Direct Connect.
- C. Correct.
Correct: A cross-connect must be established between your network equipment and the AWS Direct Connect endpoint located in the colocation facility.
- D. Correct.
Correct: If your on-premises environment is not directly connected to the colocation facility, you need a leased line from an AWS Partner Network (APN) provider to bridge the gap.
- E. Correct.
Correct: BGP is required for routing on the Direct Connect connection. It establishes the communication between your on-premises network and AWS.
