ANS-C01 Question 463
Select 3Your organization has a hybrid cloud architecture and uses AWS Direct Connect to establish a private connection between the on-premises data center and AWS. You are tasked with ensuring high availability and fault tolerance for the Direct Connect connection. Which of the following approaches should you implement to meet this requirement?
- A
Establish multiple Direct Connect connections in different AWS Regions.
- B
Use a single Direct Connect connection and enable Virtual Private Gateway failover.
- C
Establish multiple Direct Connect connections at different Direct Connect locations within the same AWS Region.
- D
Combine Direct Connect with a VPN as an automatic failover mechanism.
- E
Enable BGP (Border Gateway Protocol) with multiple redundant paths.
Show answer and explanation
Correct answers: C, D, E
Explanation
To ensure high availability and fault tolerance for AWS Direct Connect, it is recommended to establish multiple Direct Connect connections at different locations within the same Region. This redundancy protects against failures of a single connection or location. Additionally, integrating Direct Connect with a VPN as a failover mechanism adds an extra layer of resilience, ensuring traffic can still route to AWS if Direct Connect fails. Finally, configuring BGP with multiple redundant paths ensures that routing is seamless and resilient to connection issues.
- A. Incorrect.
Establishing multiple Direct Connect connections in different AWS Regions does not address high availability within a single Region, and it increases complexity unnecessarily unless cross-region redundancy is specifically required.
- B. Incorrect.
Using a single Direct Connect connection with Virtual Private Gateway failover does not provide fault tolerance for the Direct Connect connection itself. It only provides failover for the traffic routing.
- C. Correct.
Establishing multiple Direct Connect connections at different Direct Connect locations within the same AWS Region is a recommended practice for high availability, as it ensures redundancy in case one connection or location fails.
- D. Correct.
Combining Direct Connect with a VPN provides an automatic failover mechanism in case the Direct Connect connection goes down, improving fault tolerance.
- E. Correct.
Enabling BGP with multiple redundant paths ensures seamless failover for routing and connectivity, further enhancing availability and fault tolerance.
