[All Professional Cloud Network Engineer Questions]

Your organization is connecting their Shared VPC network to their on-premises data center by using Dedicated Interconnect to provide connectivity to all of its service projects. You need to create a design to configure your VLAN attachments and Cloud Routers. You also want to achieve a 99.9% Cloud Interconnect SLA based on Google Cloud s reference design. What should you do?

A. Create two Cloud Interconnect connections in different edge availability domains of two different co-location facilities in a project that will contain your connections. Create one VLAN attachment and Cloud Router for each physical interconnect in the Shared VPC host project.
B. Create two Interconnect connections in different edge availability domains of the co-location facility in a project that will contain your connections. Create one VLAN attachment for each physical Cloud Interconnect connection and a single Cloud Router in the Shared VPC host project.
C. Create two Cloud Interconnect connections in different edge availability domains of the co-location facility in a project that will contain your connections. Create one VLAN attachment for each physical interconnect and a single Cloud Router in the service projects.
D. Create two Cloud Interconnect connections in different edge availability domains of the co-location facility in a project that will contain your connections. Create a Cloud Router in the Shared VPC host project and the VLAN attachments in the Shared VPC service projects.

Selected Answer: B

B The correct design ensures redundancy for high availability (99.9% SLA) and follows the best practice of placing the Cloud Router and VLAN attachments in the Shared VPC host project for centralized management. The interconnection itself can be created within any project.

Selected Answer: B

Requirements for 99.9% Cloud Interconnect SLA: Redundant Dedicated Interconnect connections: Two physical interconnects in different edge availability domains within the same metro/colocation facility. One VLAN attachment per interconnect: Ensures that traffic can fail over properly. Single Cloud Router: It can manage both BGP sessions over both VLAN attachments. Hosted in Shared VPC host project: Networking infrastructure (VLAN attachments, Cloud Router) should live in the host project where the networking is centrally managed.

Selected Answer: B

Your goal is to configure Dedicated Interconnect to connect your Shared VPC to the on-premises data center while achieving a 99.9% SLA based on Google's reference design. Key Requirements for 99.9% SLA: Redundant Interconnects: You must have two Cloud Interconnect connections in different edge availability domains (within the same co-location facility). VLAN Attachments: Each Cloud Interconnect connection must have one VLAN attachment. Cloud Router Placement: A single Cloud Router in the Shared VPC host project is recommended because it simplifies BGP route management for all service projects.
