Google Professional Cloud Developer Question 206

Select 3Google Cloud Platform

You are developing a cloud-based application that uses Google Cloud Pub/Sub and Firestore as part of its architecture. To minimize costs and speed up your local development workflow, you decide to emulate these services on your local machine. Which of the following steps should you take to correctly configure and use the emulators for local development?

  1. A

    Install the Google Cloud SDK and use the gcloud CLI to start the Pub/Sub and Firestore emulators.

  2. B

    Set the PUBSUB_EMULATOR_HOST and FIRESTORE_EMULATOR_HOST environment variables in your local environment.

  3. C

    Deploy the Pub/Sub and Firestore services to a dedicated Google Cloud project for testing purposes.

  4. D

    Use the Cloud Console to configure and start emulators directly from the browser.

  5. E

    Modify your application’s configuration to point to the emulator endpoints during local development.

Correct answers: A, B, E

Explanation

To effectively emulate Google Cloud services like Pub/Sub and Firestore for local development, you need to install and start the emulators using the Google Cloud SDK. Additionally, environment variables such as PUBSUB_EMULATOR_HOST and FIRESTORE_EMULATOR_HOST must be set to direct your application to use the local emulators. Finally, you need to modify your application configuration to point to these emulator endpoints, ensuring it interacts with the emulated services instead of actual cloud resources. This approach reduces costs and allows for faster iteration during development.

  • A. Correct.

    Correct. The Google Cloud SDK includes emulators for Pub/Sub and Firestore, which can be started locally using the gcloud CLI.

  • B. Correct.

    Correct. Setting these environment variables ensures that your application interacts with the local emulators instead of the actual Google Cloud services.

  • C. Incorrect.

    Incorrect. Using a dedicated Google Cloud project for testing introduces costs and doesn't leverage local emulation, which is the recommended practice for local development.

  • D. Incorrect.

    Incorrect. The Cloud Console is not used to start emulators; they must be run locally using tools such as the Google Cloud SDK.

  • E. Correct.

    Correct. During local development, your application must be configured to use the emulator endpoints instead of the production endpoints.
