Google Professional Cloud Network Engineer Question 694
Select 3Google Cloud PlatformYou are tasked with setting up a global hybrid network using Network Connectivity Center (NCC). Your organization has multiple on-premises data centers connected to Google Cloud using Cloud VPN and Dedicated Interconnect. You need to ensure that the data centers can communicate with each other through Google's backbone network while minimizing operational complexity. Which combination of configurations should you implement?
- A
Create a Network Connectivity Center hub and attach spokes for each on-premises data center.
- B
Configure a Cloud Router for each spoke to advertise routes dynamically.
- C
Use VPC Network Peering to connect the on-premises networks to the NCC hub.
- D
Enable global dynamic routing in the VPC networks connected to the NCC hub.
- E
Manually configure static routes on each on-premises router to handle interconnectivity.
Show answer and explanation
Correct answers: A, B, D
Explanation
To set up a global hybrid network with Network Connectivity Center, you need to use a hub-and-spoke model to connect on-premises data centers to the NCC hub. Cloud Router ensures routes are dynamically exchanged, while global dynamic routing simplifies route propagation across the network. VPC Network Peering and manual static routes are not applicable in this scenario, as NCC provides a more efficient and scalable approach for hybrid network connectivity.
- A. Correct.
Correct: A Network Connectivity Center hub serves as the central point for managing connectivity between on-premises and cloud networks. Spokes are required to connect the on-premises data centers to the hub.
- B. Correct.
Correct: Cloud Router is necessary to dynamically exchange routes between Google Cloud and on-premises data centers, ensuring seamless communication.
- C. Incorrect.
Incorrect: VPC Network Peering is not required for NCC, as NCC uses spokes and the Google backbone network to handle connectivity.
- D. Correct.
Correct: Global dynamic routing allows VPC networks to learn and propagate routes globally, simplifying route management and ensuring proper routing through the NCC hub.
- E. Incorrect.
Incorrect: Manually configuring static routes increases operational complexity and contradicts the goal of minimizing complexity in this scenario.
