What does "Discard Old Builds" do?

Removes the logs and artifacts of older build executions

Permanently removes the source code from the remote SCM

Updates the Jenkins controller to the latest stable version

Moves the current source code to a temporary system trash

What is the "Build Pipeline View"?

A visualization of a sequence of upstream and downstream jobs

A real-time monitor for watching code being written

A dashboard used for monitoring the health of server hardware

A built-in editor for modifying application image assets

How do you parameterize a Jenkins job?

By defining variables that users set before the build starts

By entering environment variables directly into the console

By modifying the Jenkins Java source code on the server

By deleting the config.xml file from the Jenkins home path

What is a "Multi-branch Pipeline"?

A project that creates a pipeline for every branch in the SCM

A pipeline that manages physical infrastructure connections

A tool used for merging multiple code branches together

A configuration for managing multiple cloud provider accounts

What is "Artifact Archiving"?

Storing build outputs like JAR or WAR files for later use

The process of deleting build files to save storage space

Creating a historical log of every developer commit

Moving the source code to a long-term cold storage facility

What is a "Post-build Action"?

A step performed after the build, such as sending notifications

A task that re-executes the build if the first one fails

A system utility that shuts down the agent after a build

A global setting for managing user authentication levels

What is the "Jenkins API" used for?

To interact with Jenkins through external scripts or tools
