   A switch port shows a high number of 'CRC errors' but no runts or giants. The link is up at 1 Gbps full duplex. The cable is a Cat6 cable that runs through an area with heavy electrical equipment. What is the most likely cause?

   • AThe switch port is set to half duplex.
   • BThe cable is too long, causing signal attenuation.
   • CElectromagnetic interference from the electrical equipment is corrupting frames.
   • DThe connected device is sending oversized frames.

   A network administrator is designing a network for a new office. The office has 20 PCs and a server. The administrator wants to minimize collisions and improve performance. Which device should be used to connect the PCs and server?

   • AA router, because it segments broadcast domains.
   • BA switch, because it creates a separate collision domain for each port.
   • CA bridge, because it segments broadcast domains.
   • DA hub, because it is simpler and cheaper.

   A network technician is troubleshooting a switch port that shows a high number of runts and CRC errors. The port is connected to a device that is set to 10 Mbps half duplex, while the switch port is set to 100 Mbps full duplex. What is the most likely cause of the errors?

   • AThe device is generating malformed frames.
   • BSpeed and duplex mismatch between the device and the switch port.
   • CThe switch port is failing.
   • DThe cable is faulty.

   A network engineer is troubleshooting a link between two switches that is up but has a high number of late collisions and CRC errors. The engineer checks the configuration and finds that both switches are set to auto-negotiation. The engineer also checks the cable and finds it is a Cat5e cable running at 1 Gbps. The engineer suspects a duplex mismatch. What is the best way to confirm the duplex mismatch?

   • AReboot both switches.
   • BCheck the 'show interface' output on both switches to see the negotiated duplex mode.
   • CReplace the cable with a Cat6 cable.
   • DCheck the switch logs for error messages.
