Google Cloud Professional Cloud Network Engineer — Question 173

Your company has a single on-premises data center that needs to be connected to a VPC in Google Cloud. The total bandwidth requirement is 10Gbps. The connection must be redundant and have a minimum SLA of 99.9%. Due to the sensitive nature of the workloads, you need to implement the solution with the lowest latency. What should you do?

Answer options

• A. Order a 10Gbps Partner Interconnect VLAN attachment. Create a Cloud Router in your Google Cloud VPC.
• B. Order two 10Gbps Dedicated Interconnect connections in a single metropolitan area (metro). Distribute the connections across different edge availability domains. Create a Cloud Router and two 10Gbps VLAN attachments.
• C. Create one HA VPN gateway. Create two tunnels-one tunnel for each of the two interfaces of the HA VPN gateway. Terminate each of the two tunnels on the single public IP address that is configured on the VPN termination device that is located on-premises.
• D. Create one HA VPN gateway. Create two tunnels-one tunnel for each of the two interfaces of the HA VPN gateway. Terminate each of the two tunnels on different public IPs addresses that are configured on the VPN termination device that is located on-premises.

Correct answer: B

Explanation

The correct answer is B because it provides two Dedicated Interconnect connections, ensuring redundancy and meeting the bandwidth requirement with low latency. Options A, C, and D do not meet the necessary bandwidth and SLA requirements or do not provide the needed redundancy for sensitive workloads.
