    Your organization is deploying a single project for 3 separate departments. Two of these departments require network connectivity between each other, but the third department should remain in isolation. Your design should create separate network administrative domains between these departments. You want to minimize operational overhead.
    How should you design the topology?

    You have an application hosted on a Compute Engine virtual machine instance that cannot communicate with a resource outside of its subnet. When you review the flow and firewall logs, you do not see any denied traffic listed.
    During troubleshooting you find:
    * Flow logs are enabled for the VPC subnet, and all firewall rules are set to log.
    * The subnetwork logs are not excluded from Stackdriver.
    * The instance that is hosting the application can communicate outside the subnet.
    * Other instances within the subnet can communicate outside the subnet.
    * The external resource initiates communication.
    What is the most likely cause of the missing log lines?

    You are in the early stages of planning a migration to GCP. You want to test the functionality of your hybrid cloud design before you start to implement it in production. The design includes services running on a Compute Engine Virtual Machine instance that need to communicate to on-premises servers using private IP addresses. The on-premises servers have connectivity to the internet, but you have not yet established any Cloud Interconnect connections. You want to choose the lowest cost method of enabling connectivity between your instance and on-premises servers and complete the test in 24 hours.
    Which connectivity method should you choose?

    You have configured a Compute Engine virtual machine instance as a NAT gateway. You execute the following command:
    gcloud compute routes create no-ip-internet-route \
    --network custom-network1 \
    --destination-range 0.0.0.0/0 \
    --next-hop instance nat-gateway \
    --next-hop instance-zone us-central1-a \
    --tags no-ip --priority 800
    You want existing instances to use the new NAT gateway. Which command should you execute?
