You converted an auto mode VPC network to custom mode. Since the conversion, some of your Cloud Deployment Manager templates are no longer working. You want to resolve the problem.
What should you do?

1. A. Apply an additional IAM role to the Google API’s service account to allow custom mode networks.
2. B. Update the VPC firewall to allow the Cloud Deployment Manager to access the custom mode networks.
3. C. Explicitly reference the custom mode networks in the Cloud Armor whitelist.
4. D. Explicitly reference the custom mode networks in the Deployment Manager templates.

Correct Answer: D

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?

1. A. Create a more specific route than the system-generated subnet route, pointing the next hop to instance-B with no tag.
2. 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.
3. C. Delete the system-generated subnet route and create a specific route to instance-B with a tag applied to instance-A.
4. D. Move instance-B to another VPC and, using multi-NIC, connect instance-B's interface to instance-A's networ
5. E. Configure the appropriate routes to force traffic through to instance-A.

Correct Answer: B

You have provisioned a Dedicated Interconnect connection of 20 Gbps with a VLAN attachment of 10 Gbps. You recently noticed a steady increase in ingress traffic on the Interconnect connection from the on-premises data center. You need to ensure that your end users can achieve the full 20 Gbps throughput as quickly as possible. Which two methods can you use to accomplish this? (Choose two.)

1. A. Configure an additional VLAN attachment of 10 Gbps in another regio
2. B. Configure the on-premises router to advertise routes with the same multi-exit discriminator (MED).
3. C. Configure an additional VLAN attachment of 10 Gbps in the same regio
4. D. Configure the on-premises router to advertise routes with the same multi-exit discriminator (MED).
5. E. From the Google Cloud Console, modify the bandwidth of the VLAN attachment to 20 Gbps.
6. F. From the Google Cloud Console, request a new Dedicated Interconnect connection of 20 Gbps, and configure a VLAN attachment of 10 Gbps.
7. G. Configure Link Aggregation Control Protocol (LACP) on the on-premises router to use the 20-Gbps Dedicated Interconnect connection.

Correct Answer: CE

You are configuring load balancing for a standard three-tier (web, application, and database) application. You have configured an external HTTP(S) load balancer for the web servers. You need to configure load balancing for the application tier of servers. What should you do?

1. A. Configure a forwarding rule on the existing load balancer for the application tier.
2. B. Configure equal cost multi-path routing on the application servers.
3. C. Configure a new internal HTTP(S) load balancer for the application tier.
4. D. Configure a URL map on the existing load balancer to route traffic to the application tier.

Correct Answer: A

You are using a 10-Gbps direct peering connection to Google together with the gsutil tool to upload files to Cloud Storage buckets from on-premises servers. The on-premises servers are 100 milliseconds away from the Google peering point. You notice that your uploads are not using the full 10-Gbps bandwidth available to you. You want to optimize the bandwidth utilization of the connection.
What should you do on your on-premises servers?

1. A. Tune TCP parameters on the on-premises servers.
2. B. Compress files using utilities like tar to reduce the size of data being sent.
3. C. Remove the -m flag from the gsutil command to enable single-threaded transfers.
4. D. Use the perfdiag parameter in your gsutil command to enable faster performance: gsutil perfdiag gs://[BUCKET NAME].
