Which of the following should be followed before connecting to Amazon Virtual Private Cloud (Amazon VPC) using AWS Direct Connect?
Provide a public Autonomous System Number (ASN) to identify your network on the Internet.
Create a virtual private gateway and attach it to your Virtual Private Cloud (VPC).
Allocate a private IP address to your network in the 122.x.x.x range.
Provide a public IP address for each Border Gateway Protocol (BGP) session.
Explanations:
A public ASN is not required for connecting to Amazon VPC using AWS Direct Connect, as AWS uses private ASNs for Direct Connect connections.
Creating a virtual private gateway and attaching it to the VPC is a necessary step for establishing a connection between AWS Direct Connect and the VPC. This enables routing of traffic from the Direct Connect connection to the VPC.
The 122.x.x.x IP range is a public IP address range, and allocating a private IP address is not part of the requirements for connecting to VPC using Direct Connect. Private IP addresses should be in the ranges defined by RFC 1918 (e.g., 10.x.x.x, 172.16.x.x to 172.31.x.x, 192.168.x.x).
While providing a public IP address for each BGP session may be necessary in some contexts, it is not specifically required for AWS Direct Connect connections. AWS Direct Connect typically uses private IP addresses for BGP sessions established between the customer router and the AWS router.
