Microsoft GH-900 - GitHub Foundations

It is recommended to deploy from your feature branch before merging into the main branch to ensure the changes are verified and validated in a production environment . This practice helps in identifying any potential issues or bugs in a real-world scenario before the changes are permanently integrated into the main branch. By deploying from the feature branch, developers can catch and address issues early, reducing the risk of introducing bugs into the main branch, which is usually considered the stable branch.

=================

When using GitHub Codespaces, you can customize several aspects of the development environment:

Shell : You can choose the default shell to be used in the Codespace, such as Bash, Zsh, or PowerShell.

Name : Users can customize the name of their Codespace for easier identification.

Default editor : You can choose which editor to use within the Codespace, such as Visual Studio Code or others that may be supported.

Branch protections and the operating system are not customizable for an individual Codespace within GitHub, making the options Shell, Name, and Default editor the correct answers.

=================

To highlight a post at the top of the Discussions page on GitHub, you can Pin the discussion . Pinning a discussion ensures it remains prominently visible at the top of the list, making it easier for others to find and participate in that discussion. This is particularly useful for important announcements or frequently referenced topics.

=================

The following two-factor authentication (2FA) methods can be used to secure a GitHub account:

A. Authenticator app : You can use an authenticator app (like Google Authenticator or Authy) to generate time-based one-time passwords (TOTP) for logging in.

C. GitHub mobile : The GitHub mobile app can also be used to receive 2FA codes, adding convenience for users who prefer to manage everything from their mobile devices.

D. Security keys : Physical security keys (such as YubiKeys) can be used as a strong form of 2FA, requiring physical access to the key to authenticate.

Security questions and Single sign-on (SSO) are not considered 2FA methods in the context of GitHub account security.
