Google Professional Cloud Network Engineer Question 696
Select 2Google Cloud PlatformYour organization needs to create a hybrid connectivity solution between its on-premises data center and Google Cloud. The solution should allow for low-latency, high-bandwidth communication, and ensure traffic is routed securely. The organization also needs to connect to multiple VPCs in Google Cloud while maintaining centralized management. Which combination of components would best achieve this?
- A
Use Dedicated Interconnect for hybrid connectivity and create a single VPC with subnetworks spanning multiple regions.
- B
Use Partner Interconnect for hybrid connectivity and configure multiple VPN tunnels to each VPC.
- C
Use Cloud VPN for hybrid connectivity and implement VPC peering between the connected VPCs.
- D
Use Dedicated Interconnect for hybrid connectivity and configure a Cloud Router with multiple VLAN attachments to connect to a Shared VPC.
- E
Use Partner Interconnect for hybrid connectivity and use a Hub-and-Spoke architecture with Network Connectivity Center (NCC) to connect multiple VPCs.
Show answer and explanation
Correct answers: D, E
Explanation
To meet the requirements of low-latency, high-bandwidth connectivity and centralized management of multiple VPCs, Dedicated Interconnect or Partner Interconnect are the best options. Dedicated Interconnect with Cloud Router and VLAN attachments ensures efficient hybrid connectivity while maintaining centralized routing through a Shared VPC. Alternatively, Partner Interconnect combined with a Hub-and-Spoke architecture using Network Connectivity Center (NCC) allows for centralized management and scalable multi-VPC connections.
- A. Incorrect.
Using Dedicated Interconnect provides low-latency, high-bandwidth connectivity. However, creating a single VPC with subnetworks spanning multiple regions may violate organizational requirements for multi-VPC architecture and centralized management.
- B. Incorrect.
Partner Interconnect allows hybrid connectivity but configuring multiple VPN tunnels to each VPC is inefficient and does not provide centralized management.
- C. Incorrect.
Cloud VPN provides secure connectivity, but it is not ideal for high-bandwidth, low-latency requirements. VPC peering is also decentralized and may not scale well for multiple VPCs.
- D. Correct.
Dedicated Interconnect with Cloud Router and multiple VLAN attachments enables high-bandwidth hybrid connectivity and centralized routing. Using a Shared VPC allows you to manage networking resources centrally.
- E. Correct.
Partner Interconnect with a Hub-and-Spoke architecture using Network Connectivity Center (NCC) provides a scalable and centralized solution for connecting multiple VPCs while maintaining hybrid connectivity.
