Google Professional Cloud Network Engineer Question 74
Single answerGoogle Cloud PlatformYou are designing a hybrid network architecture for your company. Your organization requires a connection between two VPC networks in Google Cloud located in separate regions. Additionally, you need to establish connectivity between these VPCs and an on-premises environment via a dedicated interconnect. The solution should minimize latency between the VPCs and avoid transitive routing through the on-premises network. Which solution should you implement?
- A
Use VPC Network Peering between the two VPC networks and set up a Dedicated Interconnect for the on-premises connection.
- B
Use VPC Network Peering with Network Connectivity Center to connect the VPCs and the on-premises environment.
- C
Use Private Service Connect to link the two VPC networks and set up a Dedicated Interconnect for the on-premises connection.
- D
Configure Cloud VPN tunnels between the two VPC networks and use a Dedicated Interconnect for on-premises connectivity.
Show answer and explanation
Correct answer: A
Explanation
The best solution to connect two VPC networks in separate regions while avoiding transitive routing through the on-premises environment is to use VPC Network Peering. This ensures low-latency communication between the VPCs. For the on-premises connection, a Dedicated Interconnect provides the required high-bandwidth, low-latency link. Other options such as Private Service Connect or Cloud VPN tunnels are not suitable for the stated requirements.
- A. Correct.
This is the correct option. VPC Network Peering allows direct communication between VPC networks in different regions without transiting through the on-premises environment. Additionally, setting up a Dedicated Interconnect ensures a low-latency, high-bandwidth connection to the on-premises network.
- B. Incorrect.
This option is incorrect because Network Connectivity Center is typically used for centralized network management and interconnectivity in more complex architectures. For this scenario, direct VPC Network Peering suffices.
- C. Incorrect.
This option is incorrect because Private Service Connect is designed for connecting services via private endpoints, not for direct VPC-to-VPC communication.
- D. Incorrect.
This option is incorrect because using Cloud VPN tunnels introduces higher latency and isn't optimal for VPC-to-VPC connectivity in the same cloud environment.
