ANS-C01 Question 130
Select 2Your organization needs to establish secure and high-performance connectivity between its on-premises data center and the AWS Cloud. The workload involves large-scale data transfers and requires consistent bandwidth. Additionally, the architecture must ensure fault tolerance and low latency. What combination of connectivity options would best meet these requirements?
- A
Use AWS Direct Connect with a dedicated connection and configure a second Direct Connect connection for redundancy.
- B
Establish a Site-to-Site VPN over the internet and enable BGP for route propagation.
- C
Leverage a single AWS Direct Connect connection supplemented by a Site-to-Site VPN as a backup.
- D
Deploy AWS Transit Gateway and configure it with multiple VPN connections for fault-tolerant routing.
- E
Use Direct Connect Gateway to aggregate multiple Direct Connect connections across Regions.
Show answer and explanation
Correct answers: A, E
Explanation
To meet the requirements of high performance, low latency, fault tolerance, and consistent bandwidth for large-scale data transfers, AWS Direct Connect is the optimal solution. Configuring a second Direct Connect connection for redundancy ensures fault tolerance. Additionally, Direct Connect Gateway can aggregate connections across regions, further enhancing the connectivity architecture. VPN solutions are not ideal for this workload due to their dependency on the internet, which introduces latency and bandwidth variability.
- A. Correct.
Correct: AWS Direct Connect provides high-performance, low-latency connectivity between on-premises and AWS. Configuring a second Direct Connect connection ensures redundancy and fault tolerance.
- B. Incorrect.
Incorrect: Site-to-Site VPN over the internet is not ideal for high-performance workloads or consistent bandwidth requirements due to potential latency and bandwidth fluctuations.
- C. Incorrect.
Incorrect: While a single Direct Connect supplemented with a VPN can provide backup, this setup does not ensure high throughput or optimal redundancy for large-scale workloads.
- D. Incorrect.
Incorrect: AWS Transit Gateway with multiple VPN connections is suitable for multi-VPC routing but does not meet the performance and low-latency requirements of the scenario.
- E. Correct.
Correct: Direct Connect Gateway allows you to aggregate multiple Direct Connect connections, providing improved fault tolerance and supporting multi-region architectures.
