ANS-C01 Question 195
Select 3Your organization is planning to establish a dedicated network connection between their on-premises data center and AWS using AWS Direct Connect. As part of this process, you need to work with a colocation facility to set up the physical connection. Which of the following steps are necessary to complete the setup for AWS Direct Connect at Layer 1?
- A
Obtain a Letter of Authorization (LOA) from AWS to connect to the AWS Direct Connect endpoint.
- B
Configure a BGP session to establish routing between your on-premises network and AWS.
- C
Provision a cross-connect in the colocation facility where the AWS Direct Connect endpoint is located.
- D
Install and configure a virtual private gateway (VGW) in the target AWS VPC.
- E
Verify the physical connection and ensure it meets the colocation facility's requirements.
Show answer and explanation
Correct answers: A, C, E
Explanation
Setting up AWS Direct Connect at Layer 1 focuses on the physical connection between your network and the AWS Direct Connect endpoint. This includes obtaining the LOA from AWS to authorize the connection, provisioning the cross-connect in the colocation facility, and verifying the physical connection to ensure it meets the facility's requirements. Tasks like configuring BGP sessions and virtual private gateways are part of higher-layer configurations and do not pertain to Layer 1.
- A. Correct.
Obtaining a Letter of Authorization (LOA) from AWS is mandatory to connect your equipment to the AWS Direct Connect endpoint in the colocation facility.
- B. Incorrect.
Configuring a BGP session is a Layer 3 task, and while important for routing, it is not relevant to the physical Layer 1 setup.
- C. Correct.
Provisioning a cross-connect is an essential step in the colocation facility to physically connect your network device to the AWS Direct Connect endpoint.
- D. Incorrect.
Installing and configuring a virtual private gateway (VGW) is part of the logical network setup and does not relate to Layer 1 or the physical connection.
- E. Correct.
Verifying the physical connection ensures that the hardware is properly installed and meets the colocation facility's requirements, which is crucial for completing the Layer 1 setup.
