Google Cloud Certified - Professional Cloud Network Engineer Sample Questions (Q43-Q48):
NEW QUESTION # 43
You work for a university that is migrating to GCP.
These are the cloud requirements:
* On-premises connectivity with 10 Gbps
* Lowest latency access to the cloud
* Centralized Networking Administration Team
New departments are asking for on-premises connectivity to their projects. You want to deploy the most cost-efficient interconnect solution for connecting the campus to Google Cloud.
What should you do?
- A. Use Shared VPC, and deploy the VLAN attachments in the service projects. Connect the VLAN attachment to the Shared VPC's host project.
- B. Use standalone projects and deploy the VLAN attachments and Interconnects in each of the individual projects.
- C. Use Shared VPC, and deploy the VLAN attachments and Interconnect in the host project.
- D. Use standalone projects, and deploy the VLAN attachments in the individual projects. Connect the VLAN attachment to the standalone projects' Interconnects.
Answer: C
Explanation:
https://cloud.google.com/interconnect/docs/how-to/dedicated/using-interconnects-other-projects Using Cloud Interconnect with Shared VPC You can use Shared VPC to share your VLAN attachment in a project with other VPC networks. Choosing Shared VPC is preferable if you need to create many projects and would like to prevent individual project owners from managing their connectivity back to your on-premises network. In this scenario, the host project contains a common Shared VPC network usable by VMs in service projects. Because VMs in the service projects use this network, Service Project Admins don't need to create other VLAN attachments or Cloud Routers in the service projects. In this scenario, you must create VLAN attachments and Cloud Routers for a Cloud Interconnect connection only in the Shared VPC host project. The combination of a VLAN attachment and its associated Cloud Router are unique to a given Shared VPC network. https://cloud.google.com/network-connectivity/docs/interconnect/how-to/enabling-multiple-networks-access-same-attachment#using_with
