You are increasing your usage of Cloud VPN between on-premises and GCP, and you want to support more traffic than a single tunnel can handle. You want to increase the available bandwidth using Cloud VPN.
What should you do?

• A.Double the MTU on your on-premises VPN gateway from 1460 bytes to 2920 bytes.
• B.Create two VPN tunnels on the same Cloud VPN gateway that point to the same destination VPN gateway IP address.
• C.Add a second on-premises VPN gateway with a different public IP address. Create a second tunnel on the existing Cloud VPN gateway that forwards the same IP range, but points at the new on-premises gateway IP.
• D.Add a second Cloud VPN gateway in a different region than the existing VPN gateway. Create a new tunnel on the second Cloud VPN gateway that forwards the same IP range, but points to the existing on-premises VPN gateway IP address.

You work for a university that is migrating to GCP.
These are the cloud requirements:
* On-premises connectivity with 10 Gbps
* Lowest latency access to the cloud
* Centralized Networking Administration Team
New departments are asking for on-premises connectivity to their projects. You want to deploy the most cost-efficient interconnect solution for connecting the campus to Google Cloud.
What should you do?

• A.Use Shared VPC, and deploy the VLAN attachments and Interconnect in the host project.
• B.Use Shared VPC, and deploy the VLAN attachments in the service projects. Connect the VLAN attachment to the Shared VPC's host project.
• C.Use standalone projects, and deploy the VLAN attachments in the individual projects. Connect the VLAN attachment to the standalone projects' Interconnects.
• D.Use standalone projects and deploy the VLAN attachments and Interconnects in each of the individual projects.

You have deployed a proof-of-concept application by manually placing instances in a single Compute Engine zone. You are now moving the application to production, so you need to increase your application availability and ensure it can autoscale.
How should you provision your instances?

• A.Create a single managed instance group, specify the desired region, and select Multiple zones for the location.
• B.Create a managed instance group for each region, select Single zone for the location, and manually distribute instances across the zones in that region.
• C.Create an unmanaged instance group in a single zone, and then create an HTTP load balancer for the instance group.
• D.Create an unmanaged instance group for each zone, and manually distribute the instances across the desired zones.

You have created several preemptible Linux virtual machine instances using Google Compute Engine. You want to properly shut down your application before the virtual machines are preempted. What should you do?

• A.Create a shutdown script registered as a xinetd service in Linux and configure a StackDriver endpoint check to call the service.
• B.Create a shutdown script, registered as a xinetd service in Linux, and use the gcloud compute instances add-metadata command to specify the service URL as the value for a new metadata entry with the key shutdown-script-url
• C.Create a shutdown script named shutdown in the /etc/ directory.
• D.Create a shutdown script and use it as the value for a new metadata entry with the key shutdown- script in the Cloud Platform Console when you create the new virtual machine instance.

In order to provide subnet level isolation, you want to force instance-A in one subnet to route through a security appliance, called instance-B, in another subnet.
What should you do?

• A.Create a more specific route than the system-generated subnet route, pointing the next hop to instance-B with no tag.
• B.Create a more specific route than the system-generated subnet route, pointing the next hop to instance-B with a tag applied to instance-A.
• C.Delete the system-generated subnet route and create a specific route to instance-B with a tag applied to instance-A.
• D.Move instance-B to another VPC and, using multi-NIC, connect instance-B's interface to instance-A's network. Configure the appropriate routes to force traffic through to instance-A.
