Q: A Local Area Network (LAN) uses Category 6 cabling. An issue with a connection results in a network link degradation and only one device can communicate at a time, but information can still go in either direction. What is the connection operating at?

Q: Category 6 cabling is used in local area networks, or LANs. Information may still flow in both directions even when a connection problem causes a network link degradation, which limits the number of devices that can talk simultaneously. At what speed is the connection running?
- Simplex
- Half Duplex
- Partial
- Full Duplex
Explanation: The fact that only one device at a time is capable of communicating yet information may still go in either way is indicative of a half-duplex functioning under the scenario that has been described. Devices that are using half-duplex communication are only able to send or receive data at any one moment; they cannot do both at the same time. This may be an indication of a problem with the network or a misconfiguration that’s causing it to degrade to half-duplex mode. Local Area Networks (LANs) should ideally be wired using Category 6 cable and configured correctly so that they run in full-duplex mode. This would make it possible for devices to communicate with one another in both directions simultaneously.
