What is containerization in the context of DevOps?

Running multiple virtual machines on a single physical server

Automating the deployment of code to production

Packaging an application with its dependencies into a lightweight, isolated environment

Storing application code in a version control system

A development team is experiencing issues where an application works on a developer's laptop but fails in the test environment. The team suspects the issue is due to differences in the operating system and installed libraries. Which DevOps practice would MOST directly address this problem?

Increasing the frequency of code reviews

Implementing a more comprehensive monitoring solution

Using containerization to package the application and its dependencies

Adding more unit tests to the test suite

A team is using a test automation framework for a web application. They have a suite of end-to-end tests that are flaky, failing intermittently without any code changes. The team is spending a significant amount of time investigating these failures. They are considering implementing a retry mechanism for failed tests. What is the MOST important consideration before implementing this?

Removing the flaky tests from the suite entirely

Ensuring the retry mechanism is only applied to known flaky tests, not all tests

Ignoring the flaky tests and focusing on new features

Increasing the number of retries to ensure the tests eventually pass
