Practice question 61 of 440 · medium

A user reports intermittent loss, and a physical port's error counters increase rapidly during the complaint. What is the best first investigation?

Choose the single best answer.

  1. A.Tune IPS signatures before checking the growing port-error evidence
  2. B.Change the default route while leaving physical errors unexplained
  3. C.Raise session limits without inspecting the failing link
  4. D.Check the cable/transceiver and speed/duplex/link conditions
Show the answer and explanation

✓ Correct answer

  • Check the cable/transceiver and speed/duplex/link conditions

Rising physical counters directly support cable/transceiver and speed/duplex investigation. Routing, session-limit or signature changes do not repair the evidenced link fault.
