Question: 1 / 400

You've been running App Engine applications in a Standard Environment for a few weeks. After a broken deployment, what is the fastest way to get the site back into a functioning state?

Have the developers fix the issue and deploy.

Use the gcloud app rollback command.

In the UI, click Traffic Splitting and direct 100% of the traffic to the previous version.

A and D are incorrect because they both involve waiting for the developers to fix the issue and redeploy the application. This could take a significant amount of time and your site will be unavailable during that time.

B is incorrect because using the gcloud app rollback command only rolls back the deployment, but does not fix the broken application.

The fastest way to get the site back into a functioning state is to use the Traffic Splitting feature in the App Engine UI. This allows you to direct 100% of the traffic to the previous version of your application while the developers work on fixing the issue. This way, your site can continue to run and be accessible to users while the issue is being resolved. Once the issue is fixed, you can switch back to the new deployment.
