You need to run a business-critical workload on a fixed set of Compute Engine instances for several months. The workload is stable with the exact amount of resources allocated to it. You want to lower the costs for this workload without any performance implications. What should you do?

• A.Migrate the instances to a Managed Instance Group.
• B.Convert the instances to preemptible virtual machines.
• C.Purchase Committed Use Discounts.
• D.Create an Unmanaged Instance Group for the instances used to run the workload.

You support a web application that runs on App Engine and uses CloudSQL and Cloud Storage for data storage. After a short spike in website traffic, you notice a big increase in latency for all user requests, increase in CPU use, and the number of processes running the application. Initial troubleshooting reveals:
After the initial spike in traffic, load levels returned to normal but users still experience high latency.
Requests for content from the CloudSQL database and images from Cloud Storage show the same high latency.
No changes were made to the website around the time the latency increased.
There is no increase in the number of errors to the users.
You expect another spike in website traffic in the coming days and want to make sure users don't experience latency. What should you do?

• A.Modify the App Engine configuration to have additional idle instances.
• B.Upgrade the GCS buckets to Multi-Regional.
• C.Enable high availability on the CloudSQL instances.
• D.Move the application from App Engine to Compute Engine.

You support an e-commerce application that runs on a large Google Kubernetes Engine (GKE) cluster deployed on-premises and on Google Cloud Platform. The application consists of microservices that run in containers. You want to identify containers that are using the most CPU and memory. What should you do?

• A.Use Stackdriver Kubernetes Engine Monitoring.
• B.Use Stackdriver Logging to export application logs to BigOuery. aggregate logs per container, and then analyze CPU and memory consumption.
• C.Use Prometheus to collect and aggregate logs per container, and then analyze the results in Grafana.
• D.Use the Stackdriver Monitoring API to create custom metrics, and then organize your containers using groups.
