[All Professional Cloud DevOps Engineer Questions]

You deploy a new release of an internal application during a weekend maintenance window when there is minimal user tragic. After the window ends, you learn that one of the new features isn't working as expected in the production environment. After an extended outage, you roll back the new release and deploy a fix.
You want to modify your release process to reduce the mean time to recovery so you can avoid extended outages in the future. What should you do? (Choose two.)

A. Before merging new code, require 2 different peers to review the code changes.
B. Adopt the blue/green deployment strategy when releasing new code via a CD server.
C. Integrate a code linting tool to validate coding standards before any code is accepted into the repository.
D. Require developers to run automated integration tests on their local development environments before release.
E. Configure a CI server. Add a suite of unit tests to your code and have your CI server run them on commit and verify any changes.

Pretty sure some answers are wrong on purpose. B&E are the only suitable options, as they talk about CI/CD.

Definitely B, as this will reduce recovery time as the question asks for. I would think D over E, as the problem states 'not working as expected in production'. Unit tests might not spot an environment specific or application behaviour related issue, whereas automated integration tests are more likely too e.g. might test with DB integration, mocked services.
