Port mirroring (also known as SPAN - Switched Port Analyzer) is considered one of the best ways to counter packet monitoring on a switch. This technique involves copying traffic from one or more switch ports (or an entire VLAN) to another port where the monitoring device is connected. Port mirroring allows administrators to monitor network traffic in a non-intrusive way, as it does not affect network performance and is transparent to users and endpoints on the network. Reference:
Cisco Systems, 'Catalyst Switched Port Analyzer (SPAN) Configuration Example'.

Duplication can be useful too, but SPAN is more common.

I have a vague memory of tap being used for monitoring, but I thought it was less effective than SPAN.

I'm leaning towards duplication, but I feel like I might be mixing it up with something else we covered.

I remember practicing a similar question, and I think port mirroring was mentioned as a good option too. But I can't recall the specifics.

I think SPAN is the right answer, but I'm not completely sure. We discussed it in class, and it seemed like the most effective method.

Okay, I think I've got it. SPAN, or Switched Port Analyzer, is the industry-standard way to monitor traffic on a switch without being detected.

I'm a bit confused on the difference between tap, duplication, and port mirror. I'll need to review those concepts again.

Hmm, I'm not totally sure about this one. I know that fixed costs stay the same as volume increases, but I'm not confident about the per unit change part. I'll have to think this through a bit more.

D) Port mirror, hands down. It's like having a personal bodyguard for your network traffic.
