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?

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

You have configured Cloud CDN using HTTP(S) load balancing as the origin for cacheable content. Compression is configured on the web servers, but responses served by Cloud CDN are not compressed.
What is the most likely cause of the problem?

• A.You have not configured compression in Cloud CDN.
• B.You have configured the web servers and Cloud CDN with different compression types.
• C.The web servers behind the load balancer are configured with different compression types.
• D.You have to configure the web servers to compress responses even if the request has a Via header.

You decide to set up Cloud NAT. After completing the configuration, you find that one of your instances is not using the Cloud NAT for outbound NAT.
What is the most likely cause of this problem?

• A.The instance has been configured with multiple interfaces.
• B.The instance is accessible by a load balancer external IP address.
• C.An external IP address has been configured on the instance.
• D.You have created static routes that use RFC1918 ranges.

Your on-premises data center has 2 routers connected to your GCP through a VPN on each router. All applications are working correctly; however, all of the traffic is passing across a single VPN instead of being load-balanced across the 2 connections as desired.
During troubleshooting you find:
* Each on-premises router is configured with the same ASN.
* Each on-premises router is configured with the same routes and priorities.
* Both on-premises routers are configured with a VPN connected to a single Cloud Router.
* The VPN logs have no-proposal-chosen lines when the VPNs are connecting.
* BGP session is not established between one on-premises router and the Cloud Router.
What is the most likely cause of this problem?

• A.You do not have a load balancer to load-balance the network traffic.
• B.BGP sessions are not established between both on-premises routers and the Cloud Router.
• C.A firewall is blocking the traffic across the second VPN connection.
• D.One of the VPN sessions is configured incorrectly.

All the instances in your project are configured with the custom metadata enable-oslogin value set to FALSE and to block project-wide SSH keys. None of the instances are set with any SSH key, and no project-wide SSH keys have been configured. Firewall rules are set up to allow SSH sessions from any IP address range. You want to SSH into one instance.
What should you do?

• A.Set the custom metadata enable-oslogin to TRUE, and SSH into the instance using a third-party tool like putty or ssh.
• B.Open the Cloud Shell SSH into the instance using gcloud compute ssh.
• C.Generate a new SSH key pair. Verify the format of the private key and add it to the instance. SSH into the instance using a third-party tool like putty or ssh.
• D.Generate a new SSH key pair. Verify the format of the public key and add it to the project. SSH into the instance using a third-party tool like putty or ssh.
