ANS-C01 Question 186
Select 2You are designing a hybrid network connectivity solution for a company that requires low latency and high availability between their on-premises data center and their resources in AWS. The company operates in multiple AWS Regions and needs to ensure a redundant setup across Regions. Which of the following solutions would best meet these requirements?
- A
Use AWS Direct Connect with multiple connections in multiple Direct Connect locations and enable Direct Connect Gateway.
- B
Establish multiple VPN connections over the public internet and configure BGP for dynamic routing.
- C
Set up AWS Transit Gateway in each Region and connect them using inter-Region peering.
- D
Deploy a single AWS Direct Connect connection and configure a backup VPN connection over the internet.
- E
Use AWS Global Accelerator to route traffic between the on-premises data center and AWS resources.
Show answer and explanation
Correct answers: A, C
Explanation
The combination of AWS Direct Connect with redundant connections and Direct Connect Gateway, along with AWS Transit Gateway for inter-Region connectivity, provides a robust, low-latency, and highly available solution for hybrid network connectivity across multiple Regions. VPN connections and AWS Global Accelerator do not meet the low-latency and high-availability requirements in this scenario.
- A. Correct.
This option is correct because AWS Direct Connect provides low-latency, high-bandwidth private connectivity, and using multiple connections in multiple Direct Connect locations ensures high availability. Enabling Direct Connect Gateway allows connections across multiple Regions.
- B. Incorrect.
While VPN connections over the public internet are cost-effective, they do not provide the low latency or high availability required in this scenario.
- C. Correct.
This option is correct because AWS Transit Gateway with inter-Region peering provides a highly available and scalable solution for interconnecting multiple networks, including on-premises and AWS Regions.
- D. Incorrect.
A single Direct Connect connection does not meet the high availability requirement, even with a VPN backup. If the Direct Connect connection fails, the backup VPN may not provide the same low latency.
- E. Incorrect.
AWS Global Accelerator is primarily used to improve the availability and performance of applications by routing traffic to the optimal endpoint, but it does not provide low-latency, private connectivity between on-premises and AWS resources.
