ANS-C01 Question 332
Single answerAn organization has a critical application hosted in a VPC within AWS. The application requires low-latency connectivity to an on-premises data center and must also support dynamic routing to handle failover scenarios. Which networking solution best meets these requirements?
- A
AWS Direct Connect with BGP (Border Gateway Protocol)
- B
AWS Site-to-Site VPN with static routing
- C
AWS Transit Gateway without route propagation
- D
AWS Global Accelerator
Show answer and explanation
Correct answer: A
Explanation
AWS Direct Connect with BGP is the most suitable solution for this scenario because it provides low-latency connectivity between AWS and on-premises environments. Additionally, using BGP allows for dynamic routing, which is necessary to handle failover scenarios effectively. Other options either do not support the required features or are not designed for low-latency, on-premises connectivity.
- A. Correct.
AWS Direct Connect with BGP is the best solution for low-latency connectivity and dynamic routing. BGP enables dynamic route updates, which are crucial for handling failover scenarios efficiently.
- B. Incorrect.
AWS Site-to-Site VPN with static routing does not support dynamic routing, which is required for handling failover scenarios. Additionally, VPN connections typically have higher latency compared to AWS Direct Connect.
- C. Incorrect.
AWS Transit Gateway without route propagation would not support dynamic routing directly. While it can manage complex network topologies, it is not optimized for low-latency connections between AWS and on-premises environments.
- D. Incorrect.
AWS Global Accelerator is a service designed for improving user experience by providing low-latency connections to globally distributed applications. It does not establish a direct connection between AWS and on-premises environments.
