1. A team of data scientists wants to run a Python application in a Docker container. They want to minimize operational overhead, so they decide to use App Engine. They want to run the application in a Python 3.4 environment. Which configuration file would they modify to specify that runtime?

2. Customers are complaining of long waits while your e-commerce site processes orders. There are many microservices in your order processing system. You would like to view information about the time each microservice takes to run. What Stackdriver service would you use?

3. Audit control requirements at your company require that all logs be kept for at least 365 days. You prefer to keep logs and log entries in Stackdriver logging, but you understand that logs with predefined retention periods of less than 1 year will require you to set up an export to another storage system, such as Cloud Storage. Which of the following logs would you need to set up exports for to meet the audit requirement?

4. You have created a test environment for a group of business analysts to run several Cloud Dataflow pipelines. You want to limit the processing resources any pipeline can consume. What execution parameter would you specify to limit processing resources?

5. A new engineer in your group asks for your help with creating a managed instance group. The engineer knows the configuration and the minimum and maximum number of instances in the MIG. What is the next thing the engineer should do to create the desired MIG?

6. A Cloud Bigtable instance with one cluster is not performing as expected. The instance was created for analytics. Data is continuously streamed from thousands of sensors, and statistical analysis programs run continually in a batch. What would you recommend to improve performance?

7. You would like to view information recorded by an application about events prior to the application crashing. What Stackdriver service would you use?

8. Your team is experimenting with Cloud Functions to build a pipeline to process images uploaded to Cloud Storage. During the development stage, you want to avoid sudden spikes in Cloud Functions use because of errors in other parts of the pipeline, particularly the test code that uploads test images to Cloud Storage. How would you reduce the risk of running large numbers of Cloud Functions at one time?

9. You are running a high-performance computing application in a managed instance group. You notice that the throughput of one instance is significantly lower than that for other instances. The poorly performing instance is terminated, and another instance is created to replace it. What feature of managed instance groups is at work here?

10. A Kubernetes administrator wants to improve the performance of an application running in Kubernetes. They have determined that the four replicas currently running are not enough to meet demand and want to increase the total number of replicas to six. The name of the deployment is my-app-123. What command should they use?

11. You have provisioned a Kubernetes Engine cluster and deployed an application. The application load varies during the day, and you have configured autoscaling to add replicas when CPU utilization exceeds 60 percent. How is that CPU utilization calculated?

12. You would like to collect data on the memory utilization of instances running in a particular managed instance group. What Stackdriver service would you use?

13. A Cloud Dataproc cluster is running with a single master node. You have determined that the cluster needs to be highly available. How would you increase the number of master nodes to 3?

14. A group of data scientists wants to preprocess a large dataset that will be delivered in batches. The data will be written to Cloud Storage and processed by custom applications running on Compute Engine instances. They want to process the data as quickly as possible when it arrives and are willing to pay the cost of running up to 10 instances at a time. When a batch is finished, they’d like to reduce the number of instances to 1 until the next batch arrives. The batches do not arrive on a known schedule. How would you recommend that they provision Compute Engine instances?

15. Your team is migrating applications from running on bare-metal servers and virtual machines to running in containers. You would like to use Kubernetes Engine to run those containers. One member of the team is unfamiliar with Kubernetes and does not understand why they cannot find a command to deploy a container. How would you describe the reason why there is no deploy container command?
