Which type of end user license is being purchased when the number of client access licenses matches the number of devices that will access the software at one time?

The correct answer is based on the understanding of how client access licenses (CALs) function in relation to software usage. When an organization purchases client access licenses that match the number of devices accessing the software simultaneously, they are effectively acquiring a network/multiuser license.

This type of license permits multiple users or devices to access a server or software concurrently, facilitating shared use across the network. Such licensing is common in enterprise environments where numerous devices may need to connect to centralized software or services, allowing organizations to scale their usage based on actual access requirements.

In contrast, other license types don't accommodate this scenario as effectively. A single-user license restricts software use to one individual or one device at any given time. An individual/multiuser license might suggest a more limited configuration that doesn't necessarily account for concurrent access by multiple devices. General public licenses typically refer to software that is freely available to use by anyone, which doesn't apply to a controlled access environment.

Thus, the network/multiuser license appropriately describes the scenario where device access aligns with the number of purchased licenses, enabling efficient software usage across an organization's infrastructure.
