Explanation

Option A is correct because a monitoring port (also called a SPAN port or mirror port) is specifically designed to copy traffic from one or more source ports/VLANs and forward that copied traffic to a destination port connected to a monitoring device such as a network analyzer, IDS, or packet capture tool - without interrupting the original traffic flow. This is the fundamental definition and purpose of port mirroring/monitoring in network switches. Option B is incorrect because it contradicts this well-established networking feature that is supported by virtually all managed switches and is widely used in network security, troubleshooting, and performance analysis.

Memory tip: Think of a monitoring port as a "one-way mirror" - traffic flows normally on the mirrored (source) port, while the monitoring port silently reflects a copy to your analysis device. The word "mirror" is the key: it duplicates without disrupting.
