To access data stored in Amazon S3 bucket from on-premise locations using AWS Direct Connect, which of the following interface & routing protocols require to be configured?

Answer options:

A.Public VIF with BGP Routing Protocol
B.Private VIF with BGP Routing Protocol
C.Public VIF with Static Routing Protocol
D.Private VIF with Static Routing Protocol

Correct Answer: A
AWS Direct Connect provides a dedicated network connectivity from on-premise to AWS. AWS Direct Connect supports only the BGP routing protocol for this connectivity. It supports multiple virtual connections on a single physical link. To access public resources on AWS, Public Virtual Interface needs to be created. To access resources within VPC, a Private Virtual Interface is required.
Option B is incorrect as Public VIF is required (not Private VIF) for accessing public resources within AWS cloud like Amazon S3 bucket. Private VIF is used to access resources within Amazon VPC.Options C & D are incorrect as AWS Direct Connect only supports BGP routing Protocol, not static routing protocol.
