Test your knowledge of Direct Connect Overview

Question 1

A company wants to use Direct Connect to connect its on-premises data center to AWS. Their requirement is to have multiple virtual interfaces in a single Direct Connect connection. Should they use hosted connections or dedicated connections?

Correct Answer: Dedicated connections

Dedicated connections allow you to have multiple virtual interfaces in a single Direct Connect connection. Hosted connections, on the other hand, only allow one virtual interface per connection.

Question 2

A company uses AWS Direct Connect as its primary connectivity to a VPC. They need to maintain connectivity during a Direct Connect outage without provisioning any additional Direct Connect circuits. What should they implement?

Correct Answer: Configure an AWS Site-to-Site VPN as a backup

Setting up an AWS Site-to-Site VPN as a backup provides resilient connectivity over the internet if the Direct Connect (DX) link fails, without requiring any additional DX circuits. You can terminate the VPN on the same virtual private gateway (VGW) or Transit Gateway used by DX and use BGP to prefer DX under normal conditions and automatically fail over to the VPN during outages. Options like S3 Transfer Acceleration and Multi-AZ deployment do not address network path redundancy to the VPC, and adding another DX circuit contradicts the stated constraint of not provisioning additional DX connections.

Question 3

A company wants to improve its on-premises connectivity to AWS with a dedicated network connection. Although cost is important, their priority is a consistent network performance. Which AWS service should they use?

Correct Answer: AWS Direct Connect

AWS Direct Connect provides a dedicated connection to AWS, which ensures consistent network performance. Although other options offer various advantages, none provide the same level of consistency and dedication as Direct Connect.
