What will the value of $server be in the notify resource after executing the node declaration for "webserver.mylabserver.com"?

In Puppet, when a node declaration is executed, the values of variables can depend on how the configuration is set in the Puppet manifest. In this particular case, the variable $server is likely set based on facts gathered about the node or a specified parameter in the resource declaration.

Assuming that the node "webserver.mylabserver.com" is appropriately configured to correspond to a specific IP address within the Puppet manifests, the value of $server being set to 10.0.0.2 suggests a defined relationship between that specific node and the IP address. This IP address is likely designated for the webserver role assigned to that node in the overall Puppet architecture.

Such configuration often appears in a manifest that looks something like this:

node 'webserver.mylabserver.com' {

$server = '10.0.0.2'

notify { "Server IP: ${server}": }

}

Here, when the declaration for the node is executed, $server is explicitly assigned as '10.0.0.2', and thus it will hold that value when used in the notify resource. The notify function will then output this value as part of its message
