Why might new users have difficulty logging on to a network if the office has more than 20 employees running Windows 11?

The reason the selected answer is correct revolves around the limitations imposed by network configurations rather than a direct limitation of Windows 11 itself.

Windows 11 can technically support more than 20 users on a network; however, in specific networking environments, such as those using Windows server versions, a restriction may apply when more than 20 simultaneous users attempt to connect. This is typically the case with peer-to-peer networks or systems that are not managed by a server with appropriate licensing. When there are more than 20 users trying to log into the network, new users may start to experience logon difficulties due to this limitation, causing them to be unable to connect if the network is not set up to handle additional users effectively.

The other options imply hardware or software capability issues, which do not accurately reflect the common behavior of Windows 11. Windows 11 is indeed designed to facilitate network connectivity rather than block it, and the common infrastructure issues or licensing aspects are more relevant to the broader organization than to the operating system itself. Therefore, understanding the limitations in user connections is crucial for managing a network with a substantial number of employees effectively, especially when using an operating system like Windows 11 in such environments.
