An IT manager needs to purchase client access licenses for servers. The network has ten workstations and 100 on-site users. Which of the following licensing models should the systems administrator…

Per user Client Access Licensing assigns a CAL to each individual, allowing them to access the server from any device on the network. With 100 users requiring server access across only 10 workstations, this model ensures compliance by licensing each identity rather than each physical endpoint. It is the appropriate choice when users may roam between shared workstations and server access must be tracked per person.

Per CPU licensing applies to the server itself based on processor count and governs how many cores or CPUs a software product can use, not how many clients may connect.

Per operating system licensing governs the right to deploy OS instances on servers or virtual machines and is not a client access licensing model.

Per device licensing would require only 10 CALs for the workstations but does not account for all 100 users who each need a licensed right to access the server.
