ANS-C01 Question 462
Select 2You are designing a hybrid network architecture for a company that has on-premises data centers and workloads in AWS. The company requires a highly available connection with low latency between their on-premises environment and AWS, and they occasionally need to transfer large datasets. Which of the following combination of services and configurations would best meet these requirements?
- A
Use AWS Direct Connect with a single connection to a Direct Connect Gateway.
- B
Set up multiple AWS Direct Connect connections in separate locations for redundancy.
- C
Use AWS VPN over the public internet as the primary connection to AWS.
- D
Enable BGP (Border Gateway Protocol) for dynamic routing with AWS Direct Connect.
- E
Configure AWS Snowball for transferring large datasets to AWS.
Show answer and explanation
Correct answers: B, D
Explanation
To meet the requirements of high availability and low latency for a hybrid architecture, multiple AWS Direct Connect connections in separate locations provide redundancy, and enabling BGP ensures dynamic routing and failover capabilities. VPN over the public internet is not suitable for low-latency needs, and while AWS Snowball can be used for large dataset transfers as a separate process, it does not contribute to the continuous network connection.
- A. Incorrect.
Using a single AWS Direct Connect connection does not provide redundancy, so it is not the best choice for high availability.
- B. Correct.
Deploying multiple AWS Direct Connect connections in different locations ensures redundancy and high availability, which is suitable for the given requirements.
- C. Incorrect.
AWS VPN over the public internet is not ideal for low-latency connections and cannot match the performance of AWS Direct Connect.
- D. Correct.
Using BGP with AWS Direct Connect allows for dynamic routing and failover, which is essential for maintaining high availability in a hybrid network.
- E. Incorrect.
AWS Snowball is a good option for transferring large datasets, but it is not part of the real-time network connection and does not address the high availability or low latency requirements.
