Google Professional Cloud Network Engineer Question 107
Select 3Google Cloud PlatformYour company is implementing a hybrid cloud network to connect its on-premises data center to Google Cloud. The network must ensure high availability and low latency for critical workloads. Which of the following approaches should you implement to design a resilient and performant hybrid network?
- A
Utilize Dedicated Interconnect or Partner Interconnect with redundant connections.
- B
Rely solely on a VPN connection for on-premises to cloud connectivity.
- C
Deploy Cloud DNS to ensure low-latency name resolution for multi-region workloads.
- D
Use dynamic routing with Border Gateway Protocol (BGP) for on-premises and cloud routing.
- E
Configure only one Cloud Router for all interconnects to simplify the architecture.
Show answer and explanation
Correct answers: A, C, D
Explanation
To design a resilient and performant hybrid network, it is essential to use high-availability connectivity options like Dedicated Interconnect or Partner Interconnect with redundancy. Dynamic routing with BGP ensures efficient routing updates between on-premises and Google Cloud, while using Cloud DNS improves performance for multi-region workloads. Solely relying on VPN or using a single Cloud Router does not meet the requirements for resilience and performance.
- A. Correct.
Utilizing Dedicated Interconnect or Partner Interconnect with redundant connections ensures high availability and low-latency connectivity between on-premises and Google Cloud. This is critical for a resilient hybrid network.
- B. Incorrect.
Relying solely on a VPN connection does not provide the high performance and reliability required for critical workloads. VPNs are typically slower and less resilient compared to interconnect options.
- C. Correct.
Deploying Cloud DNS helps ensure low-latency name resolution, especially for multi-region and hybrid workloads, contributing to a performant network design.
- D. Correct.
Using dynamic routing with BGP allows automatic route updates between on-premises and Google Cloud, ensuring a more resilient and efficient network.
- E. Incorrect.
Configuring only one Cloud Router introduces a single point of failure, which is not aligned with designing a resilient network. Multiple Cloud Routers are recommended for redundancy.
