What device physically copies packets for analysis and can be placed on a network before the analyzer?

• A. Managed Device
• B. VPC
• C. Break and Inspect (TLS/SSL Inspection)
• D. Network Tap

Answer: (D)

The device that copies packets for analysis and can sit on a network path before the analyzer is a network tap. A network tap is designed to passively mirror traffic from a link to a separate monitoring port, so the analyzer receives a copy of every frame without interfering with the original data flow. This makes it ideal for passive monitoring and analysis, because you get an accurate view of the traffic as it travels the network. Other options don’t fit as a dedicated traffic-copy hardware solution. A generic managed device isn’t specifically about duplicating packets for analysis. A VPC refers to a virtual network in a cloud environment, not a physical tap for packet copying. Break and Inspect TLS/SSL is a method for decrypting and inspecting encrypted traffic, typically implemented inline and affecting traffic flow, rather than simply copying packets for analysis.
