Question

Quizplus · Accepted Answer

POP (Point of Presence) is the location where the customer's leased line connects to the ISP's network. This is where the ISP aggregates and manages the connectivity to the customer's network. NAP (Network Access Point) is a location where multiple ISPs interconnect their networks to exchange traffic, which is not directly related to the customer's leased line connection. CSU/DSU (Channel Service Unit/Data Service Unit) is a device that connects the customer's router to the leased line, but it is not specific to the ISP's network. Interface is a general term used to describe a connection between two devices but does not provide any context about the specific connection being discussed.
