How can you undo the actions labeled as 5 of yum command?

The command to undo actions in the yum package manager works by referencing a specific transaction ID to reverse or undo its effects. The correct answer is to use the command yum history undo 5, where "5" represents the transaction ID of the actions you want to revert.

When you run the yum history command, it provides a list of all the transactions that have been executed, along with their unique IDs. By typing yum history undo followed by the transaction ID, you instruct yum to reverse the changes made by that particular transaction, restoring the system to the state it was in prior to those changes.

This approach allows for precise control over package management, making it easy to recover from unwanted modifications. It is particularly useful in cases where a package update or removal may have caused issues.

The other options do not correctly achieve the intended outcome. For example, yum rollback 5 is inaccurate because the rollback feature in yum is not invoked in that manner—it actually does not exist as a standalone command. Similarly, yum undo 5 is not a recognized yum command, and yum update 5 incorrectly suggests updating a package with an ID of 5, which is
