AWS Certified Advanced Networking – Specialty (ANS-C01) — Question 160
A company has an on-premises data center in the United States. The data center is connected to AWS by an AWS Direct Connect connection. The data center has a private VIF that is connected to a Direct Connect gateway.
Recently, the company opened a new data center in Europe and established a new Direct Connect connection between the Europe data center and AWS. A new private VIF connects to the existing Direct Connect gateway.
The company wants to use Direct Connect SiteLink to set up a private network between the data center in the United States and the data center in Europe.
Which solution will meet these requirements in the MOST operationally efficient manner?
Answer options
- A. Create a new public VIF from each data center. Enable SiteLink on the new public VIFs.
- B. Create a new transit VIF from each data center. Enable SiteLink on the new transit VIFs.
- C. Use the existing VIF from each data center. Enable SiteLink on the existing private VIFs.
- D. Create a new AWS Site-to-Site VPN connection between the data centers. Configure the new connection to use SiteLink.
Correct answer: C
Explanation
The correct answer is C because using the existing private VIFs allows for a seamless integration with Direct Connect SiteLink, minimizing additional configurations and maximizing efficiency. Options A and B involve creating new VIFs, which adds unnecessary complexity, while option D introduces a VPN solution that is less efficient than using Direct Connect for this purpose.
