Google Professional Cloud Network Engineer Question 690
Select 3Google Cloud PlatformYou are tasked with configuring a global networking solution for a multinational company using Google Cloud's Network Connectivity Center (NCC). The company requires seamless communication between on-premises data centers and Google Cloud workloads across multiple regions while minimizing operational complexity. Which considerations are essential for configuring Network Connectivity Center in this scenario?
- A
Ensure all spokes are attached to a single hub to maintain a centralized architecture.
- B
Configure Cloud VPN or Interconnect connections as spokes to link on-premises networks to the NCC hub.
- C
Enable VPC Network Peering between all VPCs to ensure regional communication.
- D
Verify that the IAM roles assigned to users and service accounts provide the necessary permissions to manage NCC resources.
- E
Use a single region for the NCC hub to reduce latency between all spokes.
Show answer and explanation
Correct answers: A, B, D
Explanation
Network Connectivity Center is a hub-and-spoke model designed to simplify hybrid and multi-cloud network connectivity. To configure it effectively, you need to attach all spokes to a single hub for central management, use Cloud VPN or Interconnect for on-premises connectivity, and ensure proper IAM permissions are set for managing NCC resources. VPC Network Peering is not required, and NCC is designed for global use, so limiting it to a single region is not recommended.
- A. Correct.
Correct: Using a single hub for all spokes simplifies the management of the network and ensures a centralized architecture. Network Connectivity Center is designed to operate with a hub-and-spoke topology.
- B. Correct.
Correct: Cloud VPN or Dedicated/Partner Interconnect connections can be configured as spokes to connect on-premises networks, enabling seamless hybrid connectivity through NCC.
- C. Incorrect.
Incorrect: VPC Network Peering is not required for NCC configuration. NCC handles connectivity between spokes, whether they are VPC networks or on-premises connections, without the need for peering.
- D. Correct.
Correct: Proper IAM permissions are critical for managing NCC resources, including creating hubs, attaching spokes, and monitoring connections.
- E. Incorrect.
Incorrect: Using a single region for the NCC hub does not necessarily reduce latency for global communications. NCC supports global connectivity and is designed to work across regions efficiently.
