Cat5e supports up to 1 Gbps at 100 MHz, standard for 1000BASE-T over 100 meters. Cat6 supports up to 10 Gbps at 250 MHz but is limited to 55 meters for 10GBASE-T. Cat6a supports 10 Gbps at 500 MHz over full 100 meters. Single-mode fiber uses laser light for long distances, typica…Read full explanation
A network technician is troubleshooting a connectivity issue between two directly connected switches, SW1 and SW2. Hosts on VLAN 10 connected to SW1 can ping each other but cannot ping the default gateway or any host on VLAN 10 connected to SW2. The interface on SW1 is up/up, but the interface on SW2 is up/down. What is the most likely cause of the problem?
The interface on SW2 is up/down, which typically indicates a Layer 1 issue such as a duplex mismatch. Duplex mismatch occurs when one switch is manually set to full duplex and the other to half duplex or auto-negotiation fails, causing the side expecting full duplex to report up/…Read full explanation
Refer to the exhibit. A network engineer is troubleshooting intermittent connectivity between a branch router and the upstream switch. The switch port is manually configured for full-duplex, and the Ethernet cable has been tested and is working properly. The engineer runs the show interfaces GigabitEthernet0/0 command on the router and receives the output shown. Based on the output, what is the most likely cause of the problem?
The output shows the router interface is operating in half-duplex (as indicated by 'Half-duplex' in the show interfaces output), while the switch port is manually configured for full-duplex. This duplex mismatch causes the router to use CSMA/CD and detect collisions, while the sw…Read full explanation
