What will be the value of the variable $title if the node's certificate name is webserver01.mylabserver.com?

In Puppet, the value of the variable $title is derived from the node's certificate name, which in this case is webserver01.mylabserver.com. Puppet assigns the title based on the fully qualified domain name (FQDN) of the node, which includes the hostname and domain name.

When using the default behavior, the variable $title takes the base hostname of the node. For the given certificate name, this indicates that the title will be "webserver01," essentially stripping away the domain part of the FQDN. Therefore, within the context of a Puppet manifest where $title is used, it refers specifically to the "title" as the representative name given to the defined resource, based closely on the node's identity.

This means that the title variable reflects the actual designation of the node in Puppet configurations, aligning it with the intended purpose of enabling Puppet to identify and manage resources more effectively. It is important to note that the title is made available in the context of resource definitions, ensuring Puppet can apply manifests in an organized manner that concerns each node's unique positioning in the architecture it manages.
