Question

Your company currently has a Direct Connect connetion to AWS.

There is a requirement to access private EC2 servers over Direct Connect and then these private EC2 servers would access the S3 content.

There is also a requirement to access the S3 endpoint directly from the on-premises environment.

Which of the following can be used to meet this requirement? Choose 2 answers from the options given below.

A. B. C. D.

Answer - A and D.

To connect to AWS public endpoints (for example, Amazon EC2 or Amazon S3) with dedicated network performance, use a public virtual interface.

To connect to private services such as an Amazon VPC with dedicated network performance, use a private virtual interface.

To meet the requirement of accessing private EC2 servers over Direct Connect and then accessing S3 content, we need to establish a connection between on-premises environment and the VPC hosting the private EC2 instances. This can be done using a Virtual Private Network ( VPN) or a Direct Connect (DX) private virtual interface (VIF).

A private VIF can be used to establish a private virtual interface between on-premises environment and the VPC. This allows traffic to flow between on-premises environment and the VPC over a private connection. This private VIF can be used to access the private EC2 instances within the VPC and then access the S3 content from the EC2 instances.

To access the S3 endpoint directly from the on-premises environment, we can use a public VIF or a DX hosted VIF. A public VIF allows traffic to flow between on-premises environment and AWS services such as S3 over a public connection. This is useful when we need to access public services such as S3 from on-premises environment.

A hosted VIF is a connection that is hosted by a DX partner. With a hosted VIF, we can connect to an AWS service such as S3 through the DX partner's network. This allows us to access AWS services such as S3 from on-premises environment without having to establish a public VIF.

Therefore, the options that can be used to meet the requirements are:

A. A Private Virtual Interface - to access private EC2 servers over Direct Connect. B. A Hosted Virtual Interface or a Public Virtual Interface - to access S3 content directly from the on-premises environment.
