   A CodeBuild project that trains an ML model fails during the build phase with the error 'Cannot find module numpy'. The buildspec.yml installs dependencies using pip, and the build runs in a managed Ubuntu image. The team confirms the requirements.txt file is present in the source. What is the most likely cause of the failure?

   • AThe managed image does not support Python and cannot run pip commands.
   • BThe build project's service role lacks permission to access the S3 bucket where the source is stored.
   • CThe buildspec.yml file is not named correctly and CodeBuild is using a default buildspec that skips installation.
   • DThe install phase is missing or does not run pip install -r requirements.txt before the build phase.

   A team runs a CodeBuild project that trains a large ML model. The build takes about 55 minutes, and the team notices that the build sometimes fails with the error 'Build timed out after 60 minutes.' They want to increase the timeout to 90 minutes. The project uses a managed image and the default service role. What should the team do?

   • AModify the service role to allow the build to run longer.
   • BUse a custom Docker image and increase the timeout to 90 minutes in the buildspec.
   • CIncrease the compute size of the build project to speed up the build and avoid the timeout.
   • DUpdate the build project's timeout setting to 90 minutes in the CodeBuild console or via the AWS CLI.
