You need to immediately change the storage class of an existing Google Cloud bucket. You need to reduce service cost for infrequently accessed files stored in that bucket and for all files that will be added to that bucket in the future. What should you do?

• A.Use the gsutil to rewrite the storage class for the bucket Change the default storage class for the bucket
• B.Create a new bucket and change the default storage class for the bucket import the files from the previous bucket into the new bucket
• C.Use the gsutil to rewrite the storage class for the bucket Set up Object Lifecycle management on the bucket
• D.Create a new bucket and change the default storage class for the bucket Set up Object Lifecycle management on lite bucket

Your projects incurred more costs than you expected last month. Your research reveals that a development GKE container emitted a huge number of logs, which resulted in higher costs. You want to disable the logs quickly using the minimum number of steps. What should you do?

• A.1. Go to the GKE console, and delete existing clusters.
  2. Recreate a new cluster.
  3. Clear the option to enable legacy Stackdriver Monitoring.
• B.1. Go to the Logs ingestion window in Stackdriver Logging, and disable the log source for the GKE Cluster Operations resource.
• C.1. Go to the GKE console, and delete existing clusters.
  2. Recreate a new cluster.
  3. Clear the option to enable legacy Stackdriver Logging.
• D.1. Go to the Logs ingestion window in Stackdriver Logging, and disable the log source for the GKE container resource.

You have a single binary application that you want to run on Google Cloud Platform. You decided to automatically scale the application based on underlying infrastructure CPU usage. Your organizational policies require you to use virtual machines directly. You need to ensure that the application scaling is operationally efficient and completed as quickly as possible. What should you do?

• A.Create an instance template, and use the template in a managed instance group that scales up and down based on the time of day.
• B.Use a set of third-party tools to build automation around scaling the application up and down, based on Stackdriver CPU usage monitoring.
• C.Create a Google Kubernetes Engine cluster, and use horizontal pod autoscaling to scale the application.
• D.Create an instance template, and use the template in a managed instance group with autoscaling configured.

You want to configure autohealing for network load balancing for a group of Compute Engine instances that run in multiple zones, using the fewest possible steps. You need to configure re-creation of VMs if they are unresponsive after 3 attempts of 10 seconds each. What should you do?

• A.Create a managed instance group. Set the Autohealing health check to healthy (HTTP)
• B.Create an HTTP load balancer with a backend configuration that references an existing instance group.
  Define a balancing mode and set the maximum RPS to 10.
• C.Create a managed instance group. Verify that the autoscaling setting is on.
• D.Create an HTTP load balancer with a backend configuration that references an existing instance group. Set the health check to healthy (HTTP)

Your VMs are running in a subnet that has a subnet mask of 255.255.255.240. The current subnet has no more free IP addresses and you require an additional 10 IP addresses for new VMs. The existing and new VMs should all be able to reach each other without additional routes. What should you do?

• A.Create a new subnet with the same starting IP but a wider range to overwrite the current subnet.
• B.Delete the subnet, and recreate it using a wider range of IP addresses.
• C.Use gcloud to expand the IP range of the current subnet.
• D.Create a new project. Use Shared VPC to share the current network with the new project.
