AWS Certified Advanced Networking – Specialty (ANS-C01) — Question 263
A company has two AWS Direct Connect connections between Direct Connect locations and the company's on-premises environment in the US. The company uses the connections to communicate with AWS workloads that run in the us-east-1 Region. The company has a transit gateway that connects several VPCs. The Direct Connect connections terminate at a Direct Connect gateway and the transit VIFs to the transit gateway.
The company recently acquired a smaller company that is based in Europe. The newly acquired company has only on-premises workloads. The newly acquired company does not expect to run workloads on AWS for the next 3 years. However, the newly acquired company requires connectivity to the parent company's AWS resources in us-east-1 and to the parent company's on-premises environment in the US. The parent company wants to use two new Direct Connect connections in Europe to provide the required connectivity.
Which solution will meet these requirements with the LEAST operational overhead for the newly acquired company?
Answer options
- A. Associate new transit VIFs to the existing Direct Connect gateway. Configure the new transit VIFs to use Direct Connect SiteLink.
- B. Associate new transit VIFs to a new Direct Connect gateway and to a new transit gateway in the eu-west-1 Region. Use transit gateway peering to connect the transit gateways.
- C. Associate new private VIFs to the existing Direct Connect gateway. Configure the existing transit VIFs and the new private VIFs to use Direct Connect SiteLink.
- D. Associate new private VIFs to a new Direct Connect gateway and to a new VPC in us-east-1. Configure the existing transit VIFs and the new private VIFs to use Direct Connect SiteLink and AWS PrivateLink endpoints in the new VPC.
Correct answer: A
Explanation
Option A is correct because it allows the newly acquired company to utilize existing infrastructure with minimal changes, leveraging Direct Connect SiteLink for connectivity. The other options involve creating new gateways or VPCs, which would increase operational complexity and overhead, making them less suitable for the requirements.
