A developer accidentally commits a large binary file. What Git feature should they use to remove this file from history while retaining current changes?
- rebase
- reset
- filter-branch
- reflog
The correct option is filter-branch. This Git command allows the modification of the repository's commit history, including the removal of sensitive or large files. It's crucial to be cautious when using this command as it can rewrite history, impacting collaborators.
In Git, the __________ file can be used to enforce code quality standards across all project contributors.
- .gitignore
- .gitattributes
- .gitconfig
- .gitkeep
The .gitattributes file is used to enforce code quality standards across all project contributors by specifying attributes for files in the repository. It helps in maintaining consistency and best practices.
The command git _______ is used to create a new branch and switch to it in one step.
- branch
- checkout -b
- newbranch
- switchbranch
The correct command is git checkout -b . This command creates a new branch and switches to it in one step, saving you from the need to create a branch and then switch to it separately.
How does Git ensure data integrity in large repositories?
- Periodic manual checks by administrators
- Automatic garbage collection
- Ignoring large files during commits
- Disabling history tracking for certain files
Git ensures data integrity in large repositories through automatic garbage collection. This process identifies and removes unnecessary or unreferenced objects, maintaining the integrity and efficiency of the repository over time.
Which command is used to create a new Git repository?
- git create
- git init
- git new
- git start
The correct command to create a new Git repository is git init. This initializes a new repository in the current directory, preparing it for version control. Other options provided are not standard Git commands for creating a repository.
In learning from Git failures, it's often found that improper management of ________ can lead to significant issues.
- branches
- repositories
- merge conflicts
- permissions
Improper management of merge conflicts can lead to significant issues in Git. Merge conflicts arise when changes in different branches cannot be automatically merged. Proper conflict resolution and communication are essential to avoid disruptions in the development process.
A 'detached HEAD' state in Git occurs when you check out a specific _______ instead of a branch.
- Commit
- Tag
- Remote
- Branch
A 'detached HEAD' state occurs when you check out a specific commit instead of a branch. In this state, you are no longer on any branch, and any new commits will not be associated with a branch, potentially leading to data loss if not handled carefully.
The command git _______ can be used to find a list of all commits that could be causing a merge conflict.
- history
- log
- blame
- diff
The git log command is used to view the commit history. By examining the log, you can identify the commits that may be causing a merge conflict.
In what scenario is rebasing preferred over merging in Git?
- Rebasing is preferred when working on a feature branch that you want to keep clean and incorporate the latest changes from the main branch.
- Rebasing should be used when there are conflicts between branches to create a new, unified commit.
- Rebasing is suitable only for small projects with a limited commit history.
- Rebasing is recommended when you want to preserve the existing branch structure and history.
In-depth Rebasing is beneficial for creating a linear history, especially when working on feature branches, to avoid unnecessary merge commits.
What is the first step to start using Git after installation?
- Initialize a repository
- Commit changes
- Clone a repository
- Stage changes
The first step to start using Git is to initialize a repository using the git init command. This sets up a new Git repository, allowing you to start tracking your project and version controlling your files.
