You have a Linux VM that must connect to Cloud SQL. You created a service account with the appropriate access rights. You want to make sure that the VM uses this service account instead of the default Compute Engine service account. What should you do?

• A.When creating the VM via the web console, specify the service account under the `Identity and API Access' section.
• B.Download a JSON Private Key for the service account.
  On the Project Metadata, add that JSON as the value for the key compute-engine-service- account.
• C.Download a JSON Private Key for the service account.
  On the Custom Metadata of the VM, add that JSON as the value for the key compute-engine- service-account.
• D.Download a JSON Private Key for the service account.
  After creating the VM, ssh into the VM and save the JSON under ~/.gcloud/compute-engine- service-account.json.

You have a batch workload that runs every night and uses a large number of virtual machines (VMs). It is fault- tolerant and can tolerate some of the VMs being terminated. The current cost of VMs is too high. What should you do?

• A.Run a test using N1 standard VMs instead of N2. If the test is successful, use N1 Standard VMs when running future jobs.
• B.Run a test using a managed instance group. If the test is successful, use N1 Standard VMs in the managed instance group when running future jobs.
• C.Run a test using simulated maintenance events. If the test is successful, use N1 Standard VMs when running future jobs.
• D.Run a test using simulated maintenance events. If the test is successful, use preemptible N1 Standard VMs when running future jobs.

You have one GCP account running in your default region and zone and another account running in a non-default region and zone. You want to start a new Compute Engine instance in these two Google Cloud Platform accounts using the command line interface. What should you do?

• A.Activate two configurations using gcloud configurations activate [NAME]. Run gcloud configurations list to start the Compute Engine instances.
• B.Create two configurations using gcloud config configurations create [NAME]. Run gcloud configurations list to start the Compute Engine instances.
• C.Create two configurations using gcloud config configurations create [NAME]. Run gcloud config configurations activate [NAME] to switch between accounts when running the commands to start the Compute Engine instances.
• D.Activate two configurations using gcloud configurations activate [NAME]. Run gcloud config list to start the Compute Engine instances.

You and your team have been working on a new application over the past couple weeks. While it's still in development, it's becoming a bit costly for your limited budget. The entire team had a meeting on Friday to talk about how to save money until you're able to launch. One of your team members suggested shutting down some services overnight and during the weekend. Though no official decision was made before leaving for the weekend, a junior team member sent out an email saying he found a solution to the problem.
When arriving at the office on Monday, you find that your project is no longer in the drop-down inside the Console. What's the most likely reason for the missing project?

• A.The engineer clicked the "shut down" link thinking it was like a light switch that he could toggle on and off.
• B.Your trial credits expired, and the project was removed.
• C.The engineer removed the project and attached all of the resources directly to the Organization.
• D.The project was moved to another account.

You need to run an important query in BigQuery but expect it to return a lot of records. You want to find out how much it will cost to run the query. You are using on-demand pricing. What should you do?

• A.Use the command line to run a dry run query to estimate the number of bytes read. Then convert that bytes estimate to dollars using the Pricing Calculator.
• B.Arrange to switch to Flat-Rate pricing for this query, then move back to on-demand.
• C.Use the command line to run a dry run query to estimate the number of bytes returned. Then convert that bytes estimate to dollars using the Pricing Calculator.
• D.Run a select count (*) to get an idea of how many records your query will look through. Then convert that number of rows to dollars using the Pricing Calculator.
