What is the expected value of the resource named centos64c in the provided hosts?

The expected value of the resource named centos64c corresponds to the specific host's IP address associated with that resource. In this context, the correct answer, which is 10.20.1.75, likely indicates that this is the designated IP for the resource named centos64c as defined in the infrastructure or configuration management setup.

In Puppet, resources are typically associated with certain attributes such as hostname or IP address, which are defined in manifests or configurations. When determining the expected value, it is essential to understand how these resources are mapped within the configuration, ensuring that the selected IP aligns correctly with the identifiers in use.

The other options, while being valid IP addresses, do not represent the expected value for the given resource name. If 10.20.1.75 is explicitly linked to centos64c, it confirms that any desired operations with that resource will correctly reference the resource's actual configuration, leading to the successful application of Puppet manifests or other automation tasks associated with that host.
