Show answer and explanation
Correct answers: A, C
Explanation
To adjust application traffic splitting parameters in Google App Engine, you can either use the Google Cloud Console or the gcloud command line tool to define how traffic should be distributed between different versions. The Console provides an easy-to-use interface, while the gcloud tool allows for more advanced configurations, such as cookie-based splitting. These are the recommended methods for traffic management in App Engine, as opposed to using firewall rules, load balancers, or configuration files like app.yaml, which are not designed for this purpose.
- A. Correct.
A. This option is correct. The Google Cloud Console provides a straightforward interface to set traffic splitting policies between different versions of your application.
- B. Incorrect.
B. This option is incorrect. Firewall rules are not used for traffic splitting between application versions; they are used to control access to resources.
- C. Correct.
C. This option is correct. Using the gcloud command line tool, you can specify traffic splitting strategies, such as cookie-based splitting, to control the distribution of traffic between versions.
- D. Incorrect.
D. This option is incorrect. The app.yaml file is used for application configuration, but it does not directly support traffic splitting configuration.
- E. Incorrect.
E. This option is incorrect. While a load balancer can manage traffic distribution, it is not needed for App Engine's built-in version traffic splitting.
