Google Professional Cloud Network Engineer Question 274
Select 3Google Cloud PlatformYour organization is designing a global network architecture using Network Connectivity Center (NCC) in Google Cloud. The architecture includes hybrid connectivity between multiple on-premises data centers and Google Cloud projects. Which of the following considerations are essential when configuring NCC to ensure reliable and scalable connectivity?
- A
Use a single Network Connectivity Center hub to simplify connectivity across all regions.
- B
Ensure that spokes are created for each VPN gateway, VLAN attachment, or router required in the architecture.
- C
Enable VPC Network Peering between all VPC networks connected to the NCC hub.
- D
Verify that all spoke resources, such as VPN gateways or VLAN attachments, are properly associated with the correct NCC hub.
- E
Implement traffic policies in NCC to prioritize specific traffic flows and ensure optimal routing.
Show answer and explanation
Correct answers: B, D, E
Explanation
When configuring Network Connectivity Center, creating the appropriate spokes for resources, associating them with the correct hub, and implementing traffic policies are essential steps to ensure reliable and scalable connectivity. Using a single hub might not be suitable for large or global architectures, and VPC Network Peering is not directly related to NCC configuration.
- A. Incorrect.
Using a single NCC hub for all regions might cause scalability and performance concerns in large networks. It's often more efficient to create multiple hubs for different regions or use cases.
- B. Correct.
Creating spokes for each VPN gateway, VLAN attachment, or router is essential to include these resources in the NCC architecture and establish connectivity.
- C. Incorrect.
VPC Network Peering does not directly relate to NCC configuration. NCC uses spokes to manage connectivity, and peering is not required for NCC functionality.
- D. Correct.
Associating spoke resources, such as VPN gateways or VLAN attachments, with the correct NCC hub is necessary to ensure proper connectivity and avoid misconfigurations.
- E. Correct.
Traffic policies in NCC allow you to control and prioritize specific traffic flows, ensuring optimal routing and performance in your network.
