   A network admin notices that a switch port connected to a user's PC shows a high number of 'giants' and 'CRC errors' but no runts. The link is up at 1 Gbps full duplex. The cable is a new Cat6 cable. What is the most likely cause?

   • AThe switch port is set to half duplex.
   • BThe PC is sending frames faster than the switch can process.
   • CThe cable is too long, causing signal attenuation.
   • DA faulty NIC on the PC is generating corrupted frames.

   A network admin is connecting a legacy device that only supports 10 Mbps half duplex to a switch port. The switch port is configured with 'speed auto' and 'duplex auto'. The link comes up, but the switch shows the port as '10 Mbps, half duplex'. The admin wants to ensure the link operates at the best possible performance. What should the admin do?

   • ALeave the switch port as auto; the link is already at the device's maximum capability.
   • BConfigure the switch port for 100 Mbps half duplex to increase speed.
   • CReplace the device with one that supports 1 Gbps full duplex.
   • DConfigure the switch port for 10 Mbps full duplex to improve performance.

   A network engineer is troubleshooting a link between two switches that is up but experiencing a high number of CRC errors and late collisions. The engineer checks the configuration and finds that both switches are set to auto-negotiation. The cable is known-good and within distance limits. What is the most likely cause and the best next step?

   • AThe auto-negotiation failed to converge on a common duplex mode; manually set both sides to the same speed and duplex.
   • BThe switch ports are failing; replace the switch modules.
   • CThe switches are running different software versions; upgrade the software.
   • DThe cable is faulty despite being known-good; replace it with a different cable.

   A network admin connects a legacy printer to a switch port. The printer only supports 10 Mbps half duplex. The switch port is configured with 'speed 100' and 'duplex full'. What will happen?

   • AThe link will not come up because the speeds do not match.
   • BThe link will come up at 10 Mbps full duplex because the switch supports auto-negotiation.
   • CThe link will come up at 10 Mbps half duplex because the printer forces the switch to adapt.
   • DThe link will come up at 100 Mbps full duplex because the switch is the dominant device.

   A switch port shows a high number of 'runts' and 'CRC errors', but no collisions. The connected device is a printer that is known to be working. The cable is a Cat5e cable that runs through a ceiling. What is the most likely cause?

   • AThe switch port is set to half duplex.
   • BThe cable is damaged or has interference, causing signal degradation.
   • CThe printer is sending frames too fast for the switch.
   • DThe printer is using a different VLAN than the switch port.
