Google Professional Cloud Network Engineer Question 271
Select 3Google Cloud PlatformYour organization has a global network spanning multiple regions. You are tasked with setting up Google Cloud's Network Connectivity Center (NCC) to manage and monitor connectivity across on-premises locations and Google Cloud projects. Which of the following is required to create a functioning NCC hub and attach spokes for proper connectivity?
- A
At least one VPC network in the same project as the NCC hub
- B
A Cloud Router with BGP configured for each spoke attachment
- C
Spokes connecting resources such as VPN gateways, VLAN attachments, or routers
- D
A Cloud Interconnect configured in each region where spokes are deployed
- E
IAM permissions for Network Connectivity Center Admin on the project
Show answer and explanation
Correct answers: B, C, E
Explanation
To configure Network Connectivity Center (NCC), a Cloud Router with BGP is essential for dynamic routing between spokes. Spokes represent the connectivity resources, such as VPN gateways or VLAN attachments, that link on-premises and cloud environments. Additionally, the appropriate IAM permissions are needed to manage the NCC hub and its components. A VPC in the same project or Cloud Interconnect in every region is not mandatory, as NCC can span multiple projects or use alternate connectivity options.
- A. Incorrect.
Incorrect: A VPC network is not required to be in the same project as the NCC hub. Spokes can connect resources across projects as long as proper permissions are in place.
- B. Correct.
Correct: A Cloud Router with BGP must be configured for dynamic routing in order to create functional spoke attachments for NCC.
- C. Correct.
Correct: Spokes form the fundamental components of NCC and must connect resources like VPN gateways, VLAN attachments, or routers to establish connectivity.
- D. Incorrect.
Incorrect: While Cloud Interconnect enables high-performance connectivity, it is not a requirement for every region where NCC spokes are deployed. Other connectivity methods such as VPNs can also be used.
- E. Correct.
Correct: Proper IAM permissions, such as the Network Connectivity Center Admin role, are required to create and manage the NCC hub and its spokes.
