Free CompTIA Network+ N10-008 Practice Question

A network technician is troubleshooting an issue in the company’s data center where a server has intermittent connectivity problems. The switch port linked to the server shows that the connection frequently alternates between full-duplex and half-duplex modes. What is the MOST likely cause of this problem?

  • The server's network interface card is configured to 'auto-negotiate' while the switch port is statically set to 'full-duplex'.

  • The server is configured with an incorrect subnet mask.

  • The switch port and the server's network interface card are set to different VLANs.

  • The Ethernet cable connecting the server to the switch is experiencing high levels of electromagnetic interference.
