Free CompTIA Network+ N10-009 Practice Question

A network administrator is troubleshooting a newly installed Ethernet network that is experiencing slower than expected data transfer rates and intermittent connectivity issues. After ruling out hardware failures and configuration errors, the administrator suspects that signal interference might be causing the problem. Which of the following would be the BEST next step to confirm if crosstalk is the issue?

  • Replace the Ethernet cables with fiber optic cables to test if the issue persists.

  • Use a cable tester to check for crosstalk in the Ethernet cables.

  • Increase the power settings on the network routers and switches to boost signal strength.

  • Configure a VLAN to separate noisy traffic and decrease broadcast domains.
