Question 1

Your company experiences bugs, outages, and slowness in its production systems. Developers use the production environment for new feature development and bug fixes. Configuration and experiments are done in the production environment, causing outages for users. Testers use the production environment for load testing, which often slows the production systems. You need to redesign the environment to reduce the number of bugs and outages in production and to enable testers to load test new features. What should you do?

A. Create an automated testing script in production to detect failures as soon as they occur.
B. Create a development environment with smaller server capacity and give access only to developers and testers.
C. Secure the production environment to ensure that developers can't change it and set up one controlled update per year.
D. Create a development environment for writing code and a test environment for configurations, experiments, and load testing.

Correct Answer:D

Question 2

You are working with a government agency that requires you to archive application logs for seven years. You need to configure Stackdriver to export and store the logs while minimizing costs of storage. What should you do?

A. Create a Cloud Storage bucket and develop your application to send logs directly to the bucket.
B. Develop an App Engine application that pulls the logs from Stackdriver and saves them in BigQuery.
C. Create an export in Stackdriver and configure Cloud Pub/Sub to store logs in permanent storage for seven years.
D. Create a sink in Stackdriver, name it, create a bucket on Cloud Storage for storing archived logs, and then select the bucket as the log export destination.

Question 3

You use Cloud Build to build your application. You want to reduce the build time while minimizing cost and development effort. What should you do?

A. Use Cloud Storage to cache intermediate artifacts.
B. Run multiple Jenkins agents to parallelize the build.
C. Use multiple smaller build steps to minimize execution time.
D. Use larger Cloud Build virtual machines (VMs) by using the machine-type option.

https://cloud.google.com/build/docs/speeding-up-builds#caching_directories_with_google_cloud_storage Caching directories with Google Cloud Storage To increase the speed of a build, reuse the results from a
previous build. You can copy the results of a previous build to a Google Cloud Storage bucket, use the results for faster calculation, and then copy the new results back to the bucket. Use this method when your build takes a long time and produces a small number of files that does not take time to copy to and from Google Cloud Storage.

Question 4

You have a pool of application servers running on Compute Engine. You need to provide a secure solution that requires the least amount of configuration and allows developers to easily access application logs for troubleshooting. How would you implement the solution on GCP?

A. • Deploy the Stackdriver logging agent to the application servers.• Give the developers the IAM Logs Viewer role to access Stackdriver and view logs.
B. • Deploy the Stackdriver logging agent to the application servers.• Give the developers the IAM Logs Private Logs Viewer role to access Stackdriver and view logs.
C. • Deploy the Stackdriver monitoring agent to the application servers.• Give the developers the IAM Monitoring Viewer role to access Stackdriver and view metrics.
D. • Install the gsutil command line tool on your application servers.• Write a script using gsutil to upload your application log to a Cloud Storage bucket, and then schedule it to run via cron every 5 minutes.• Give the developers IAM Object Viewer access to view the logs in the specified bucket.

Question 5

Your team is designing a new application for deployment both inside and outside Google Cloud Platform (GCP). You need to collect detailed metrics such as system resource utilization. You want to use centralized GCP services while minimizing the amount of work required to set up this collection system. What should you do?

A. Import the Stackdriver Profiler package, and configure it to relay function timing data to Stackdriver for further analysis.
B. Import the Stackdriver Debugger package, and configure the application to emit debug messages with timing information.
C. Instrument the code using a timing library, and publish the metrics via a health check endpoint that is scraped by Stackdriver.
D. Install an Application Performance Monitoring (APM) tool in both locations, and configure an export to a central data storage location for analysis.

Correct Answer:A
