ANS-C01 Question 281
Select 3You are designing a hybrid network architecture for a company that requires a highly available, low-latency connection between their on-premises data center and AWS. The company needs to ensure that the connection can handle large amounts of traffic with minimal interruptions. Which combination of networking services and configurations should you choose?
- A
Set up an AWS Direct Connect connection with a secondary connection for redundancy.
- B
Use a single VPN connection over the internet to establish connectivity.
- C
Enable BGP routing over AWS Direct Connect for dynamic failover.
- D
Configure AWS Site-to-Site VPN as a backup to AWS Direct Connect.
- E
Use AWS Global Accelerator to optimize traffic routing over the Direct Connect link.
Show answer and explanation
Correct answers: A, C, D
Explanation
To meet the company's requirements for a highly available, low-latency, and high-throughput hybrid network, AWS Direct Connect should be the primary solution with a secondary connection for redundancy. BGP routing ensures dynamic failover between connections. Additionally, a Site-to-Site VPN can be configured as a backup to provide further resilience in case of failure. These configurations collectively address the need for high availability and minimal interruptions.
- A. Correct.
Correct: AWS Direct Connect provides a dedicated, high-bandwidth connection between your on-premises data center and AWS. Adding a secondary Direct Connect connection ensures redundancy in case the primary link fails.
- B. Incorrect.
Incorrect: A single VPN connection over the internet is less reliable and has higher latency compared to Direct Connect. It does not meet the requirements for high availability or low latency.
- C. Correct.
Correct: Enabling BGP routing over AWS Direct Connect allows for dynamic failover between primary and secondary connections, ensuring high availability.
- D. Correct.
Correct: Configuring AWS Site-to-Site VPN as a backup provides an additional layer of redundancy in case the Direct Connect links fail.
- E. Incorrect.
Incorrect: AWS Global Accelerator is used to optimize traffic routing for internet-facing applications, not for hybrid connectivity between on-premises and AWS.
