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

You are designing a Google Kubernetes Engine (GKE) cluster for your organization. The current cluster size is expected to host 10 nodes, with 20 Pods per node and 150 services. Because of the migration of new services over the next 2 years, there is a planned growth for 100 nodes, 200 Pods per node, and 1500 services. You want to use VPC-native clusters with alias IP ranges, while minimizing address consumption.
How should you design this topology?

• A.Create a subnet of size/25 with 2 secondary ranges of: /17 for Pods and /21 for Services. Create a VPC-native cluster and specify those ranges.
• B.Use gcloud container clusters create [CLUSTER NAME]--enable-ip-alias to create a VPC-native cluster.
• C.Use gcloud container clusters create [CLUSTER NAME] to create a VPC-native cluster.
• D.Create a subnet of size/28 with 2 secondary ranges of: /24 for Pods and /24 for Services. Create a VPC-native cluster and specify those ranges. When the services are ready to be deployed, resize the subnets.

You want to use Cloud Interconnect to connect your on-premises network to a GCP VPC. You cannot meet Google at one of its point-of-presence (POP) locations, and your on-premises router cannot run a Border Gateway Protocol (BGP) configuration.
Which connectivity model should you use?

• A.Direct Peering
• B.Dedicated Interconnect
• C.Partner Interconnect with a layer 2 partner
• D.Partner Interconnect with a layer 3 partner

All the instances in your project are configured with the custom metadata enable-osloginvalue 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.Open the Cloud Shell SSH into the instance using gcloud compute ssh.
• B.Set the custom metadata enable-oslogin to TRUE, and SSH into the instance using a third-party tool like putty or 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.
