You have a virtual machine that is currently configured with 2 vCPUs and 4 GB of memory. It is running out of memory. You want to upgrade the virtual machine to have 8 GB of memory.
What should you do?

• A.Stop the VM, change the machine type to n1-standard-8, and start the VM.
• B.Use gcloud to add metadata to the VM. Set the key to required-memory-sizeand the value to
  8 GB.
• C.Rely on live migration to move the workload to a machine with more memory.

Your company developed an application to deploy on Google Kubernetes Engine. Certain parts of the application are not fault-tolerant and are allowed to have downtime Other parts of the application are critical and must always be available. You need to configure a Goorj e Kubernfl:es Engine duster while optimizing for cost. What should you do?

• A.Create a cluster with a single node-pool by using standard VMs. Label the fault-tolerant Deployments as spot-true.
• B.Create a cluster with both a Spot W node pool and a rode pool by using standard VMs Deploy the critical.
  deployments on the Spot VM node pool and the fault; tolerant deployments on the node pool by using standard VMs.
• C.Create a cluster with a single node-pool by using Spot VMs. Label the critical Deployments as spot-false.
• D.Create a cluster with both a Spot VM node pool and by using standard VMs. Deploy the critical deployments on the mode pool by using standard VMs and the fault-tolerant deployments on the Spot VM node pool.

You are migrating a production-critical on-premises application that requires 96 vCPUs to perform its task.
You want to make sure the application runs in a similar environment on GCP. What should you do?

• A.When creating the VM, use machine type n1-standard-96.
• B.When creating the VM, use Intel Skylake as the CPU platform.
• C.Create the VM using Compute Engine default settings. Use gcloud to modify the running instance to have 96 vCPUs.
• D.Start the VM using Compute Engine default settings, and adjust as you go based on Rightsizing Recommendations.

Every employee of your company has a Google account. Your operational team needs to manage a large number of instances on Compute Engine. Each member of this team needs only administrative access to the servers. Your security team wants to ensure that the deployment of credentials is operationally efficient and must be able to determine who accessed a given instance. What should you do?

• A.Generate a new SSH key pair. Give the private key to each member of your team. Configure the public key in the metadata of each instance.
• B.Ask each member of the team to generate a new SSH key pair and to send you their public key. Use a configuration management tool to deploy those keys on each instance.
• C.Generate a new SSH key pair. Give the private key to each member of your team. Configure the public key as a project-wide public SSH key in your Cloud Platform project and allow project-wide public SSH keys on each instance.
• D.Ask each member of the team to generate a new SSH key pair and to add the public key to their Google account. Grant the "compute.osAdminLogin" role to the Google group corresponding to this team.
