Integrating Git with cloud-based IDEs in a CI/CD pipeline promotes seamless collaboration among team members, as they can access and contribute to the codebase from anywhere. This integration improves accessibility and flexibility, allowing developers to work in diverse environments. Additionally, it enhances code review processes by providing a centralized platform for reviewing changes. Slower development cycles are not a direct advantage of integration but could be a consequence if not properly implemented.

The command git reset --hard HEAD^ resets the current branch to the previous commit, discarding all changes in the working directory and staging area. It's a forceful reset, so use it with caution as it cannot be undone.

The git log command is used to view the commit history of a repository. It displays information about each commit, including the commit message, author, date, and a unique identifier. This helps in understanding the changes made in each commit in chronological order.

Git provides integrated hooks that allow scripts to run automatically after events like commits or merges. These hooks can be leveraged to automate deployment processes in DevOps practices, making the workflow more efficient and reliable.

Performing a final merge of all feature branches into the main branch consolidates all changes. This ensures that conflicts are identified and resolved collectively before the release. Option 2 suggests an alternative tool, which may not be necessary if Git is already in use. Option 3 is generally not recommended due to potential errors. Option 4 is about tagging releases but does not address conflict resolution directly.

In large, non-Git environments, transitioning existing workflows to Git can be challenging due to established practices. Addressing this challenge involves providing comprehensive training and support to ease the migration process. It is essential to communicate the benefits of Git and address concerns from team members to ensure a smooth transition.

The correct option is B. git remote add is used to manage multiple remote repositories. It allows you to associate a remote name with a URL and then refer to that remote with the given name. This is useful for fetching and pushing changes to different remote repositories.

The git status command provides information about the current state of the working directory, indicating which files are untracked, modified, or staged for the next commit.

Database schema versions can be efficiently managed using techniques like database migrations, where changes to the schema are version-controlled and applied systematically. Git hooks and Git LFS are useful for other purposes, but they may not directly address schema versioning concerns.

To efficiently manage large media files without affecting the repository's performance, the project should adopt the Git LFS (Large File Storage) strategy, specifically designed for handling such files in Git.
