CompTIA A+ Core 2 (220-1102) — Question 40

Which of the following Linux commands would be used to install an application?

Answer options

• A. yum
• B. grep
• C. ls
• D. sudo

Correct answer: A

Explanation

The command 'yum' is specifically designed for installing, updating, and managing software packages on RPM-based Linux distributions. The other options serve different purposes: 'grep' is used for searching text, 'ls' lists directory contents, and 'sudo' is used to execute commands with elevated privileges but does not install applications by itself.
