Which command would you execute to remove all certificate information for a node from the Puppet master?

To remove all certificate information for a node from the Puppet master, the appropriate command is designed specifically to handle certificate management, which is what the chosen command does. This command deletes the certificates associated with the specified node, effectively ensuring that the Puppet master no longer has any record or validation of that node's identity in its certificate authority.

When you execute this command, it addresses the entire certificate lifecycle, ensuring that any secure communications based on that certificate are discontinued. This is crucial if you want to regenerate or replace a node's certificate, or if a node is no longer in use and you want to clean up your Puppet master.

Other options, while they might seem relevant, either do not target certificate data specifically or address different functions in the Puppet ecosystem. For example, commands focused on node management or clearing cached information might not adequately handle the certificate aspects. Therefore, the right approach to completely remove the certificate is through the command that clearly outlines it— which is for cleaning certificates.
