Answer - A.

You can create a public virtual interface to connect to public resources, or a private virtual interface to connect to your VPC.

You can configure multiple virtual interfaces on a single AWS Direct Connect connection, and you'll need one private virtual interface for each VPC to connect to.

Each virtual interface needs a VLAN ID, interface IP address, ASN, and BGP key.

If one needs to establish a low latency dedicated connection to an S3 public endpoint over the Direct Connect dedicated low latency connection, the correct steps are:

Option A: Configure a public virtual interface to connect to a public S3 endpoint resource.

Explanation: Direct Connect is a service that enables customers to establish dedicated network connections between their data centers or colocation environments and AWS. Direct Connect provides low-latency connectivity and greater security than traditional internet connections. With Direct Connect, customers can access AWS services in any AWS region via a private network connection.

To establish a low latency dedicated connection to an S3 public endpoint, customers can create a public virtual interface (VIF) in Direct Connect to connect to the S3 public endpoint. A public VIF allows customers to access public AWS services such as S3 or Amazon DynamoDB over the Direct Connect connection.

To configure a public VIF, customers need to do the following:

  1. Create a public VIF in Direct Connect.
  2. Specify the S3 public endpoint as the remote router IP address for the public VIF.
  3. Configure routing on the on-premises router to direct traffic destined for the S3 public endpoint over the Direct Connect connection.

Option B: Establish a VPN connection from the VPC to the public S3 endpoint.

Explanation: VPN connection is a secure connection between the customer's on-premises environment or data center and the VPC in AWS. It provides secure and encrypted connectivity over the public internet. While a VPN connection can be used to access AWS services, it is not the recommended solution for accessing S3 public endpoint because of its high latency and increased network complexity.

Option C: Configure a private virtual interface to connect to the public S3 endpoint via the Direct Connect connection.

Explanation: A private VIF is used to access resources in a VPC over the Direct Connect connection. It is not suitable for accessing public endpoints like S3 because it is intended for private connectivity to AWS resources.

Option D: Add a BGP route as part of the on-premise router; this will route S3 related traffic to the public S3 endpoint to dedicated AWS region.

Explanation: This option is incorrect because BGP routes are used to advertise network prefixes to other routers on the internet, and they are not relevant to accessing S3 public endpoint over Direct Connect.
