What is indicated by the Netbios status <20>?

The Netbios status <20> indicates that the device is a server. Option A, B, and D are incorrect because the Netbios status <20> is not associated with a file server, workstation, or router. Netbios status <20> is a hexadecimal value that typically identifies the NetBIOS name of a host in a Windows or Samba network. This name is used for file and print sharing, as well as for other network services. Therefore, it is associated with a server rather than a file server, workstation, or router.
