D.

Tap sends traffic from physical layers to the monitoring device, while SPAN provides a copy of network traffic from switch to destination

Answers
D.

Tap sends traffic from physical layers to the monitoring device, while SPAN provides a copy of network traffic from switch to destination

Suggested answer: D

Explanation:

Tap and SPAN are two methods of capturing network traffic for analysis. Tap (Test Access Point) is a hardware device that is inserted between two network devices and sends a copy of all traffic to a monitoring device. SPAN (Switched Port Analyzer) is a software feature that allows a network switch to replicate traffic from one or more source ports to a destination port, where a monitoring device is connected. Both methods provide visibility into network traffic, but Tap is more reliable and less intrusive than SPAN, as it does not affect the network performance or introduce errors.Reference:=Understanding Cisco Cybersecurity Operations Fundamentals (CBROPS) - Cisco, page 68.
