  Which of the following allows users to provision a dedicated network connection from their internal network to AWS?

  A. AWS CloudHSM

  B. AWS Direct Connect

  C. AWS VPN

  D. Amazon Connect

  Correct Answer: B

  AWS Direct Connect lets you establish a dedicated network connection between your network and one of the AWS Direct Connect locations. Using industry standard 802.1q VLANs, this dedicated connection can be partitioned into multiple virtual interfaces. This allows you to use the same connection to access public resources such as objects stored in Amazon S3 using public IP address space, and private resources such as Amazon EC2 instances running within an Amazon Virtual Private Cloud (VPC) using private IP space, while maintaining network separation between the public and private environments. Virtual interfaces can be reconfigured at any time to meet your changing needs.
