Which command would properly clean a certificate associated with a specific node?

The command that effectively removes a certificate associated with a specific node is the clean command. Using the command puppet cert clean node1.mylabserver.com instructs Puppet to remove the certificate from the certificate authority (CA) for the specified node. This is particularly useful when you need to clear out old or invalid certificates, as it helps in maintaining an accurate state in the certificate management process.

In this case, the clean command specifically targets the certificate linked to a node and eliminates it from the CA's inventory, allowing for proper certificate management moving forward. This is essential in scenarios where nodes may need to be reissued new certificates, ensuring there are no conflicts from previous certificates. The other commands, while related to certificate management, serve different purposes and are not focused on the direct removal of a certificate from the CA.
