CompTIA A+ Core 2 (220-1102) — Question 303

Which of the following best describes when to use the YUM command in Linux?

Answer options

• A. To add functionality
• B. To change folder permissions
• C. To show documentation
• D. To list file contents

Correct answer: A

Explanation

The YUM command is primarily used to install, update, or remove software packages, which directly adds functionality to a Linux system. The other options do not pertain to the YUM command; changing folder permissions is done with 'chmod', displaying documentation is typically through 'man' or 'info', and listing file contents is done using commands like 'ls'.
