Professor Messer's CompTIA 220-1201 A+ Study Group - July 2026

Just to see if that link is working, let's try it out on something I like to call our rewind question.

The rewind question is a question that is asking about something that we've talked about before.

It's a question we had, in this case, from last month.

This is the only time you're gonna see a replay.

So if you were here last month, maybe you remember this one.

Let's try it out.

The question is, a server administrator suspects that a network interface card is malfunctioning due to high error rate notifications.

Which of the following should be used to test the interface of the Ethernet adapter? Is it A, tone generator, oh, cable tester, network tap, inductive probe, or loopback plug? And as many of you recall, when you are answering these questions, we don't answer in the chat room.

Please don't put any hints in the chat room.

Instead, you go to the link that is on your screen that I have now properly shown to you in the lower third, professormesser.com/qa.

The question again, a server administrator suspects that a network interface card is malfunctioning due to high error rate notifications.

Which of the following should be used to test the hardware interface of the Ethernet adapter? Should we use a tone generator, a cable tester, a network tap, an inductive probe, or a loopback plug? What a fine question, and we will find out the answer to that question in just a moment.
