Amazon Exam ANS-C01 Topic 1 Question 19 Discussion

Actual exam question for Amazon's ANS-C01 exam

Question #: 19
Topic #: 1

A company has two business units (BUs). The company operates in the us-east-1 Region and the us-west-1 Region. The company plans to extend to more Regions in the future. Each BU has

a VPC in each Region. Each Region has a transit gateway with the BU VPCs attached. The transit gateways in both Regions are peered.

The company will create several more BUs in the future and will need to isolate some of the BUs from the other BUs. The company wants to migrate to an architecture to incorporate more

Regions and BUs.

Which solution will meet these requirements with the MOST operational efficiency?

ACreate a new transit gateway for each new BU in each Region. Peer the new transit gateways with the existing transit gateways. Update the route tables to control traffic between BUs.

BCreate an AWS Cloud WAN core network with an edge location in both Regions. Configure a segment for each BU with VPC attachments to the new BU VPCs. Use segment actions to control traffic between segments.

CCreate an AWS Cloud WAN core network with an edge location in both Regions. Configure a segment for each BU with VPC attachments to the new BU VPCs. Configure the segments to isolate attachments to control traffic between segments.

DAttach new VPCs to the existing transit gateways. Update route tables to control traffic between BUs.

Show Suggested Answer

Suggested Answer: B

Creating a new Route 53 Resolver outbound endpoint in the shared services VPC would enable forwarding of DNS queries from the VPC to on-premises1.Creating forwarding rules for the on-premises hosted domains would enable specifying which domain names are forwarded to the on-premises DNS servers2.Associating the rules with the new Resolver endpoint and each application VPC would enable applying the rules to the VPCs2.This solution would not affect the default DNS resolution behavior of Route 53 Resolver for local VPC domain names and domains that are hosted in Route 53 private hosted zones3.

I'm just glad the question didn't involve any AWS Outposts or Wavelength Zones. That would have been a real head-scratcher.

Option D seems like the lazy way out. Just attaching new VPCs to the existing transit gateways? Where's the innovation, people? Let's go with the AWS Cloud WAN option and really impress the boss.

I bet the AWS Cloud WAN core network in options B and C will be a hit with the hipsters in the company. They'll probably want to add some blockchain integration and a microservices architecture while they're at it.

I'm not a fan of the transit gateway approach in option A. Creating a new transit gateway for each BU in each Region sounds like a lot of overhead and maintenance. Option C looks like a cleaner and more scalable solution.

That's a valid point, Annamae. But I still think creating new transit gateways for each BU will offer better control over traffic between BUs.

The question is pretty straightforward. I think option C is the best solution as it allows for the creation of an AWS Cloud WAN core network with segment isolation to control traffic between the BUs. This seems to be the most operationally efficient approach.
