Google Professional Cloud Developer Question 205
Select 3Google Cloud PlatformYou are developing a cloud-based application that uses Google Cloud Pub/Sub and Firestore. To improve your development workflow, you decide to emulate these services locally. Which of the following steps should you take to properly set up and use the emulators?
- A
Install the Google Cloud SDK and use the
gcloudcommand-line tool to start the emulators. - B
Configure your application to connect to the emulator endpoints instead of the actual Google Cloud services.
- C
Enable the required Google Cloud APIs (e.g., Pub/Sub API, Firestore API) in the Google Cloud Console.
- D
Run the emulator processes in the background while deploying your application to production.
- E
Use environment variables or configuration files to specify the emulator host and port for local testing.
Show answer and explanation
Correct answers: A, B, E
Explanation
When emulating Google Cloud services locally, the Google Cloud SDK enables developers to start emulators for services like Pub/Sub and Firestore. Configuring the application to connect to emulator endpoints is critical for proper functionality during testing. Environment variables or configuration files are commonly used to define emulator endpoints. Enabling APIs in the Google Cloud Console and running emulators in production are not required for local development and could lead to unintended consequences.
- A. Correct.
Correct. The Google Cloud SDK provides tools to start and manage emulators locally using the
gcloudcommand-line tool. - B. Correct.
Correct. To ensure your application interacts with the local emulator rather than the actual cloud services, you need to configure it to connect to the emulator endpoints.
- C. Incorrect.
Incorrect. Enabling Google Cloud APIs is relevant for actual cloud interactions, not for local emulation.
- D. Incorrect.
Incorrect. Emulators are meant for local testing and should not be used in production environments.
- E. Correct.
Correct. Using environment variables or configuration files to specify emulator host and port is a best practice for enabling seamless testing and integration with local emulators.
