You want to resolve the problem. Which commands should you run?

Your website is deployed on Compute Engine. Your marketing team wants to test conversion rates between 3 different website designs. Which approach should you use?

You need to copy directory local-scripts and all of its contents from your local workstation to a Compute Engine virtual machine instance. Which command should you use?

You are deploying your application to a Compute Engine virtual machine instance with the Stackdriver Monitoring Agent installed. Your application is a unix process on the instance. You want to be alerted if the unix process has not run for at least 5 minutes. You are not able to change the application to generate metrics or logs. Which alert condition should you configure?

You have two tables in an ANSI-SQL compliant database with identical columns that you need to quickly combine into a single table, removing duplicate rows from the result set. What should you do?

You have an application deployed in production. When a new version is deployed, some issues don't arise until the application receives traffic from users in production. You want to reduce both the impact and the number of users affected. Which deployment strategy should you use?

Your company wants to expand their users outside the United States for their popular application. The company wants to ensure 99.999% availability of the database for their application and also wants to minimize the read latency for their users across the globe.

You need to migrate an internal file upload API with an enforced 500-MB file size limit to App Engine. What should you do?

You are planning to deploy your application in a Google Kubernetes Engine (GKE) cluster. The application exposes an HTTP-based health check at /healthz. You want to use this health check endpoint to determine whether traffic should be routed to the pod by the load balancer. Which code snippet should you include in your Pod configuration?

Your teammate has asked you to review the code below. Its purpose is to efficiently add a large number of small rows to a BigQuery table. BigQuery service = BigQueryOptions.newBuilder().build().getService(); public void writeToBigQuery(Collection<Map<String, String>> rows){ for(Map<String, String> row : rows) { InsertAllRequest insertRequest = InsertAllRequest.newBuilder( "datasetId", "tableId", InsertAllRequest.RowToInsert.of(row)).build(); service.insertAll(insertRequest); } } Which improvement should you suggest your teammate make?

You are developing a JPEG image-resizing API hosted on Google Kubernetes Engine (GKE). Callers of the service will exist within the same GKE cluster. You want clients to be able to get the IP address of the service. What should you do?

You are using Cloud Build to build and test application source code stored in Cloud Source Repositories. The build process requires a build tool not available in the Cloud Build environment. What should you do?

You are deploying your application to a Compute Engine virtual machine instance. Your application is configured to write its log files to disk. You want to view the logs in Stackdriver Logging without changing the application code. What should you do?
