Question:
Your multi-region VPC has had a long-standing HA VPN configured in "region 1" connected to your corporate network. You are planning to add two 10 Gbps Dedicated Interconnect connections and VLAN attachments in "region 2" to connect to the same corporate network. You need to plan for connectivity between your VPC and corporate network to ensure that traffic uses the Dedicated Interconnect connections as the primary path and the HA VPN as the secondary path. What should you do?

You recently deployed your application in Google Cloud. You need to verify your Google Cloud network configuration before deploying your on-premises workloads. You want to confirm that your Google Cloud network configuration allows traffic to flow from your cloud resources to your on- premises network. This validation should also analyze and diagnose potential failure points in your Google Cloud network configurations without sending any data plane test traffic. What should you do?

Your company's security team tends to use managed services when possible. You need to build a dashboard to show the number of deny hits that occur against configured firewall rules without increasing operational overhead. What should you do?

You are a network administrator at your company planning a migration to Google Cloud and you need to finish the migration as quickly as possible, To ease the transition, you decided to use the same architecture as your on-premises network' a hub-and-spoke model. Your on-premises architecture consists of over 50 spokes.
Each spoke does not have connectivity to the other spokes, and all traffic IS sent through the hub for security reasons. You need to ensure that the Google Cloud architecture matches your on-premises architecture. You want to implement a solution that minimizes management overhead and cost, and uses default networking quotas and limits. What should you do?

You have the networking configuration shown. In the diagram Two VLAN attachments associated With two Dedicated Interconnect connections terminate on the same Cloud Router (mycloudrouter). The Interconnect connections terminate on two separate on-premises routers. You advertise the same prefixes from the Border Gateway Protocol (BOP) sessions associated with each Of the VLAN attachments.
You notice an asymmetric traffic flow between the two Interconnect connections. Which of the following actions should you take to troubleshoot the asymmetric traffic flow?
