What is the purpose of the command 'yum repolist all'?

• A. It lists all repositories, both enabled and disabled
• B. It lists only enabled repositories
• C. It lists only disabled repositories
• D. It refreshes repository metadata

Answer: (A)

This command is about seeing what sources yum can pull packages from. It reads the repository definitions on the system (usually in /etc/yum.repos.d and settings in /etc/yum.conf) and shows you which ones exist and whether each one is currently active.

Using the all modifier expands the view to include every configured repository, not just the ones enabled for use. That means you can see both enabled sources and those that are defined but disabled, which helps you diagnose why a certain package isn’t found or why updates aren’t coming from a particular source.

Remember, repositories are defined with an enable flag in their configuration; this command simply reports the status. It doesn’t necessarily fetch new package data on its own—if you need fresh metadata, you’d run a separate command to refresh.
