• Chose B3

  B is the correct answer

• Chose B11

  The correct answer is B. By using the App Engine's traffic splitting feature, we can easily direct a certain percentage of traffic to a specific version of our application. In this case, we want to send 1% of traffic to the new test version and keep the remaining 99% on the current version. This can be achieved by deploying the new version in the same application and using the `--splits` option to give a weight of 99 to the current version and a weight of 1 to the new version. Answer A is incorrect because the `--migrate` option is used for migrating traffic to a new version after it has been fully tested and is ready for full deployment. Answer C is incorrect because it requires additional configuration to proxy requests to the new version, increasing complexity unnecessarily. Answer D is incorrect because it involves configuring a network load balancer, which is not necessary for this use case and adds unnecessary complexity.

  While I agree with your choice and your explanation of B. I also believe C and D are wrong simply because you can only have one App Engine within a project https://cloud.google.com/appengine/docs/flexible/managing-projects-apps-billing#:~:text=Important%3A%20Each%20Cloud%20project%20can,of%20your%20App%20Engine%20application.
