A. B. C. D.Answer - B.
The AWS Documentation mentions the following.
The following information is needed for a virtual interface:
1) VLAN: Each virtual interface must be tagged with a new, unused customer-provided tag (VLAN ID) that complies with the Ethernet 802.1Q standard.
2) Peer IP addresses: The IP address ranges that are assigned to each end of the virtual interface for the BGP peering session.
3) BGP information: A virtual interface must have a public or private Border Gateway Protocol (BGP) Autonomous System Number (ASN) for your side of the BGP session.

http://docs.aws.amazon.com/directconnect/latest/UserGuide/WorkingWithVirtualInterfaces.html#vif-prerequisitesVirtual Interfaces are used to establish a private, dedicated connection between an on-premises data center and AWS. It enables users to transfer large amounts of data, which is faster, more reliable, and secure compared to the public internet. In AWS, there are two types of Virtual Interfaces - Direct Connect and VPN.
When setting up a Virtual Interface in AWS, there are several requirements to consider. The following are the requirements for establishing Virtual Interfaces in AWS:
A. VLAN ID: A VLAN ID is a unique identifier that enables traffic to be separated into different logical networks. In AWS, each Virtual Interface is associated with a VLAN ID to ensure that traffic is isolated from other traffic in the same physical connection.
B. BGP multi-exit discriminator: BGP (Border Gateway Protocol) is a protocol that enables routers to communicate with each other to determine the best path for traffic to reach its destination. BGP multi-exit discriminator is used to manipulate the path selection process by providing a hint to the receiving router about the preferred exit point for traffic.
C. An ASN for the BGP Session: An Autonomous System Number (ASN) is a unique identifier assigned by the Internet Assigned Numbers Authority (IANA) to identify a group of IP addresses that belong to the same entity. In AWS, an ASN is required to establish a BGP session with a Virtual Interface.
D. Peer IP Address: The Peer IP Address is the IP address assigned to the BGP router on the customer's side of the Virtual Interface. It is used to establish a BGP session with AWS.
Therefore, based on the above requirements, the answer to the question is Option D. Peer IP Address is not required for establishing Virtual Interfaces in AWS.
