VCP-VMC 2024 Question 163
Select 3A company is deploying VMware Cloud on AWS and plans to connect its on-premises data center to the VMware Cloud environment. They need to ensure high availability and low latency for their workloads while considering hyperscaler networking best practices. Which networking configurations should they implement?
- A
Establish a Direct Connect connection between the on-premises data center and VMware Cloud on AWS.
- B
Use a VPN over the public internet as the primary connection for critical workloads.
- C
Implement a secondary VPN connection for backup in case the primary connection fails.
- D
Configure Elastic Load Balancers (ELBs) in VMware Cloud to manage on-premises traffic.
- E
Ensure the use of Border Gateway Protocol (BGP) for routing between on-premises and VMware Cloud.
Show answer and explanation
Correct answers: A, C, E
Explanation
When designing hyperscaler networking for VMware Cloud on AWS, it is essential to follow best practices for high availability and performance. A Direct Connect connection provides a reliable, private link, while a backup VPN connection ensures redundancy. BGP is recommended for dynamic routing and seamless failover. Using VPN as the primary connection or relying on ELBs for on-premises traffic are not suitable configurations in this scenario.
- A. Correct.
Establishing a Direct Connect connection provides a dedicated, private, and low-latency link between the on-premises data center and VMware Cloud on AWS, which is a best practice for high availability and performance.
- B. Incorrect.
Using a VPN over the public internet as the primary connection for critical workloads is not recommended due to potential latency and security concerns.
- C. Correct.
Implementing a secondary VPN connection as a backup ensures redundancy in case the primary Direct Connect connection fails, which supports high availability.
- D. Incorrect.
Elastic Load Balancers (ELBs) are used to distribute traffic among instances within the hyperscaler, not to manage on-premises traffic to VMware Cloud.
- E. Correct.
Using Border Gateway Protocol (BGP) for routing is a best practice to dynamically manage routes and ensure seamless failover between the primary and secondary connections.
