Topic #: 1
[All Professional Cloud Developer Questions]

Your team detected a spike of errors in an application running on Cloud Run in your production project. The application is configured to read messages from Pub/Sub topic A, process the messages, and write the messages to topic B. You want to conduct tests to identify the cause of the errors. You can use a set of mock messages for testing. What should you do?

  • A. Deploy the Pub/Sub and Cloud Run emulators on your local machine. Deploy the application locally, and change the logging level in the application to DEBUG or INFO. Write mock messages to topic A, and then analyze the logs.
  • B. Use the gcloud CLI to write mock messages to topic A. Change the logging level in the application to DEBUG or INFO, and then analyze the logs.
  • C. Deploy the Pub/Sub emulator on your local machine. Point the production application to your local Pub/Sub topics. Write mock messages to topic A, and then analyze the logs.
  • D. Use the Google Cloud console to write mock messages to topic A. Change the logging level in the application to DEBUG or INFO, and then analyze the logs.

when emulatimg you are testing, you have to test, i think you need to read the document first then you will understand what pub/sub emulation is and how it is done. yeah the answer might not be correct because it doesnt include cloud run emulation.... you run all locally to test then you can deploy to production

You may not have experience with this, but wouldn't the main application be developed in a local environment? In the same way, it is better to develop and debug everything locally. There are various troublesome parts, and in reality, the details (Functions, Pub/Sub, etc.) are checked in the development environment, but ideally, it would be convenient if everything could be developed and debugged in the local environment. In an ideal case, it would be convenient if everything could be developed and debugged in a local environment.
