Show answer and explanation
Correct answers: A, B, E
Explanation
To configure Network Connectivity Center, you need to create a hub and attach spokes for each site. This ensures that all the networks (on-premises and VPCs) are interconnected via the NCC hub. Additionally, for on-premises networks, you must set up Cloud VPN or Cloud Interconnect to connect them to their respective spokes. Finally, IAM permissions are required to manage NCC resources effectively. Private Google Access and custom static routes are not relevant for this specific configuration.
- A. Correct.
Correct. Creating a hub in Network Connectivity Center is the first step, and attaching spokes for each site ensures connectivity through the hub.
- B. Correct.
Correct. Cloud VPN or Cloud Interconnect is necessary to connect on-premises networks to the spokes, enabling traffic flow to and from the NCC hub.
- C. Incorrect.
Incorrect. Enabling Private Google Access is not a requirement for configuring Network Connectivity Center. This feature is related to accessing Google services from private IPs in VPCs.
- D. Incorrect.
Incorrect. Routes are automatically handled by Network Connectivity Center once the hub and spokes are configured correctly. Custom static routes are not required.
- E. Correct.
Correct. Proper IAM permissions are essential to create and manage hubs and spokes in Network Connectivity Center. Without these permissions, configuration tasks cannot be completed.
