[All Professional Cloud Network Engineer Questions]

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?

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.

Selected Answer: B

A) Partner Interconnect Partner Interconnect does not meet the lowest latency requirement, as it routes through a service provider. SLA and control are dependent on the partner — not ideal for sensitive workloads requiring high control and performance. C & D) HA VPN Options VPNs are over the public internet, not suitable for sensitive workloads needing low latency and guaranteed throughput. Even with redundancy (as in D), VPN cannot achieve 10 Gbps throughput or Dedicated Interconnect-like latency.
