How does the Gitflow model handle hotfixes?
- Finish the feature branch before creating a hotfix branch
- Create a hotfix branch directly from the main branch
- Merge the hotfix branch into the main and develop branches
- Hotfixes are not supported in Gitflow
In the Gitflow model, hotfixes are created directly from the main branch to address critical issues in production. Creating a hotfix branch ensures that changes can be made and deployed without affecting the ongoing development in other branches.
How can you view a list of all the changes made in a Git repository?
- git log
- git status
- git diff
- git show
The correct option is git log. This command displays a chronological log of all commits in the repository, providing information about the commit history.
Code reviews are often performed on the changes in a _______ before they are merged into the main branch.
- development_branch
- release_branch
- feature_branch
- topic_branch
Code reviews are typically done on feature branches to ensure the quality of the code before merging.
What is the purpose of the 'HEAD' in a Git repository?
- Points to the latest commit
- Marks the branch currently in use
- Identifies the working directory state
- Represents the commit before the merge
The 'HEAD' in Git points to the latest commit in the branch, indicating the current working state. It helps identify which commit will be used as the starting point for the next commit.
A team wants to ensure that no commit messages are pushed without a specific ticket number format. Which Git Hook should they configure?
- pre-receive
- post-commit
- update
- pre-commit
In Git, the pre-commit hook is executed just before a commit is made, making it suitable for enforcing commit message formats. By configuring the pre-commit hook, the team can validate commit messages against the required ticket number format.
For database version control, the practice of _______ with Git ensures that database changes are reviewed before being deployed.
- branching
- rebasing
- forking
- tagging
In the context of database version control, the practice of rebasing with Git allows developers to incorporate changes from one branch into another. This ensures that database changes are reviewed and integrated smoothly before deployment. Rebasing helps maintain a clean and linear history, making it easier to track changes and resolve conflicts during the review process.
What is the difference between git clone and git fork?
- git clone creates a copy of a remote repository to your local machine.
- git fork creates a copy of a remote repository on the GitHub server, linked to your GitHub account.
- git clone is used for creating a copy of your local repository.
- git fork is used to create a copy of a remote repository to your local machine.
The key distinction is that git clone copies to your local machine, while git fork creates a copy on the GitHub server associated with your account.
How do you synchronize your local repository with changes from a remote repository?
- git merge origin master
- git pull origin master
- git sync origin master
- git update origin master
To synchronize your local repository with changes from a remote repository, you can use git pull origin master. This fetches changes and merges them into your local branch.
What is the main difference between git fetch and git pull?
- git fetch only downloads changes, git pull downloads changes and updates the local branch
- git fetch updates the local branch, git pull only downloads changes
- Both commands are the same
- git fetch is used for remote repositories, git pull is used for local repositories
The correct option is A. git fetch only downloads changes from the remote repository but does not automatically update the local branch. On the other hand, git pull downloads changes and updates the local branch.
In a Bitbucket repository, how can a team automate the process of sending notifications to a chat service after each commit?
- Bitbucket Webhooks
- Bitbucket Pipelines
- Bitbucket Merge Requests
- Bitbucket Forks
To automate the process of sending notifications to a chat service after each commit in a Bitbucket repository, the team should use Bitbucket Webhooks. Webhooks allow teams to integrate external services, such as chat services, and trigger actions based on repository events like commits.
