You want to configure an SSH connection to a single Compute Engine instance for users in the dev1 group. This instance is the only resource in this particular Google Cloud Platform project that the dev1 users should be able to connect to. What should you do?

• A.Set metadata to enable-oslogin=true for the instance. Grant the dev1 group the compute.osLogin role. Direct them to use the Cloud Shell to ssh to that instance.
• B.Set metadata to enable-oslogin=true for the instance. Set the service account to no service account for that instance. Direct them to use the Cloud Shell to ssh to that instance.
• C.Enable block project wide keys for the instance. Generate an SSH key for each user in the dev1 group. Distribute the keys to dev1 users and direct them to use their third-party tools to connect.
• D.Enable block project wide keys for the instance. Generate an SSH key and associate the key with that instance. Distribute the key to dev1 users and direct them to use their third-party tools to connect.

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