Google Professional Cloud Network Engineer Question 75
Single answerGoogle Cloud PlatformYour organization has two separate VPC networks, Network-A and Network-B, both in the same Google Cloud project. Network-A hosts critical internal services, while Network-B hosts analytics workloads that need to periodically access Network-A's services. However, your organization wants to minimize operational complexity, avoid transitive routing, and ensure low-latency communication between the networks. Which connectivity option would best meet these requirements?
- A
VPC Network Peering
- B
Cloud VPN
- C
Private Service Connect
- D
VPC Network Peering with Network Connectivity Center
Show answer and explanation
Correct answer: A
Explanation
VPC Network Peering directly connects two VPC networks for private, high-performance communication. It avoids transitive routing and is operationally simple, making it the best choice for this scenario. Other options like Cloud VPN and Private Service Connect are designed for different use cases, and Network Connectivity Center is unnecessary for connecting just two VPCs.
- A. Correct.
VPC Network Peering is the best option for connecting two VPC networks in the same project to allow low-latency, high-bandwidth, private communication without transitive routing. It also has minimal operational complexity since it's directly configured at the VPC level.
- B. Incorrect.
Cloud VPN is used for connecting on-premises networks or separate projects to a VPC over an encrypted public internet connection. It is not suitable for connecting two VPC networks within the same project.
- C. Incorrect.
Private Service Connect is used to connect services across different VPCs or to third-party services while abstracting the underlying network details. It is not ideal for direct VPC-to-VPC communication in the same project.
- D. Incorrect.
VPC Network Peering with Network Connectivity Center is used for complex multi-network architectures requiring centralized connectivity and policy management. It introduces unnecessary complexity for the given requirements, which only involve two VPCs in the same project.
