Google Cloud Professional Cloud Network Engineer — Question 174

You need to create the technical architecture for hybrid connectivity from your data center to Google Cloud. This will be managed by a partner. You want to follow Google-recommended practices for production-level applications. What should you do?

Answer options

• A. Ask the partner to install two security appliances in the data center. Configure one VPN connection from each of these devices to Google Cloud, and ensure that the VPN devices on-premises are in separate racks on separate power and cooling systems.
• B. Configure two Partner Interconnect connections in one metropolitan area (metro). Make sure the Interconnect connections are placed in different metro edge availability domains. Configure two VLAN attachments in a single region, and configure regional dynamic routing on the VPC.
• C. Configure two Partner Interconnect connections in one metro and two connections in another metro. Make sure the Interconnect connections are placed in different metro edge availability domains. Configure two VLAN attachments in one region and two VLAN attachments in another region, and configure global dynamic routing on the VPC.
• D. Configure two Partner Interconnect connections in one metro and two connections in another metro. Make sure the Interconnect connections are placed in different metro edge availability domains. Configure two VLAN attachments in one region and two VLAN attachments in another region, and configure regional dynamic routing on the VPC.

Correct answer: C

Explanation

Option C is correct because it ensures redundancy by having two connections in different metropolitan areas and supports global dynamic routing, which is essential for high availability and optimal performance. Options A and B do not provide sufficient redundancy or utilize global routing, while option D does not use global dynamic routing either, making option C the best choice for production-level applications.
