The Guest account has been enabled in the DESIGN domain. User John Y logs on using his account in the SALES domain. What must you do to allow JohnY to access the printer?
51324. Another drawback with repeaters is that the traffic generated on one segment is propagated onto the other segments
51325. What does the Directory Replicator service allow you to do?
51326. A route is a path between two network segments
51327. Since bridges buffer frames, it is possible to interconnect different network segments which use different MAC protocols
51328. Fibre Optic cable is often used to
51329. Workstations connected to a port on a modern lOBase-T Ethernet HUB all use the same bandwidth, i.e. the bandwidth is shared across all available ports, the less ports, the less bandwidth available per port
51330. You want to install a new internal CD-ROM drive. You must first confirm that there will be no IRQ conflicts. How should you do this?

51333. You have been given the task of installing cables for an Ethernet network in your office. The building is an older one, and-you have limited work space. In addition, the network cable will have to share the existing conduit with telephone cable, and cable segments will be up to 135 meters in length. Which cable is best suited to this installation?
51334. User Manager for domains
51335. Several college interns are working at your company for the summer. You want to increase security by monitoring all user logons. How must you do this?
51336. The system administrator wants to make sure that users have access only to certain programs on their systems. Which actions accomplish this?
