ANS-C01 Question 315
Select 2You are designing a hybrid network architecture for an organization that wants to securely connect its on-premises data center to AWS. The data center requires low latency and consistent bandwidth for critical applications, and the organization also needs to implement a failover mechanism. Which of the following solutions meets these requirements?
- A
Use AWS Direct Connect with a Site-to-Site VPN as a backup connection.
- B
Set up a single AWS Site-to-Site VPN connection between the data center and a Virtual Private Gateway (VGW).
- C
Use AWS Direct Connect with a second Direct Connect connection configured in a different AWS region for redundancy.
- D
Implement AWS Transit Gateway to manage multiple VPN connections from the on-premises data center.
- E
Set up AWS Direct Connect Gateway to aggregate multiple Direct Connect connections and enable failover.
Show answer and explanation
Correct answers: A, E
Explanation
The correct solution involves using AWS Direct Connect for low latency and consistent bandwidth, which is critical for the organization's applications. To ensure redundancy, a Site-to-Site VPN can act as a backup connection, or AWS Direct Connect Gateway can be used to aggregate multiple Direct Connect connections and enable failover. This approach provides both performance and reliability.
- A. Correct.
This is a correct option. AWS Direct Connect provides low latency and consistent bandwidth, while a Site-to-Site VPN can serve as a cost-effective failover mechanism.
- B. Incorrect.
This is incorrect because a single Site-to-Site VPN connection does not provide the required low latency and consistent bandwidth for critical applications.
- C. Incorrect.
This is incorrect because using a second Direct Connect in a different region increases complexity and does not ensure low-latency communication for the primary region.
- D. Incorrect.
This is incorrect because AWS Transit Gateway is typically used for managing multiple VPNs or VPC-to-VPC communication but does not directly address low latency and consistent bandwidth requirements.
- E. Correct.
This is a correct option. AWS Direct Connect Gateway can aggregate multiple Direct Connect connections and help in implementing a failover mechanism, ensuring reliability and performance.
