  • Multinational investment bank / DirectConnect / answer not quite right

    Q: You are working for a multinational investment bank which has multiple cloud architectures across the globe. They have a VPC in the US East region for their East Coast office and another VPC in the US West for their West Coast office. There is a requirement to establish a low latency, high-bandwidth connection between their on-premises data center in Texas and both of their VPCs in AWS.

    As the Solutions Architect, how will you implement this in a cost-effective manner?

    A1: Establish a Direct Connect connection between the VPC in US East region to the on-premise data center in Texas and then establish another Direct Connect connection between the VPC in US West region to the on-premises data center.

    A4 (marked as the correct answer): Set up an AWS Direct Connect Gateway with two virtual private gateways.

    A4 is incorrect because it doesn’t say to set up a Direct Connect connection. A Direct Connect Gateway isn’t much good without a Direct Connect Connection.

    Hi tomw,

    Thank you for sharing your feedback.

    It is as you said that a Direct Connect connection is required for the Direct Connect Gateway. For this option, I think it is safe to assume that a Direct Connect connection will be established, a Direct Connect Gateway will require one after all. Direct Connect connection is needed for this option. Also, there is a hint of “high bandwidth” connection on the question which would affirm this option too. This option provides the cost-effective solution as required for the question.

    Although on the exam some options require using multiple AWS services, so we don’t usually assume other services exist. But I still believe on this question that we can safely assume because, with a Direct Connect gateway, a Direct Connect connection is safe to assume that it exists because they are closely tied to each other.

    Hope this helps.

    There are so many questions where you have to decide between answers based on tiny details of AWS services, this big obvious gap that there is no direct connect question really stands out as clearly incorrect. You can set up a DC Gateway without a DC Connection – it just won’t do anything.
