2.8.1 - Chapter Quiz 1.Which O S I layer is associated with IP addressing? A.1 B.2 C.3 D.4 2.Which type of addressing is found at the O S I Layer 2? (Choose two.) A.logical B.physical C.MAC D.IP E.port 3.When a server responds to a web request, what occurs next in the encapsulation process after the web page data is formatted and separated into TCP segments? A.The client de-encapsulates the segment and opens the web page. B.The client adds the appropriate physical addresses to the segments so that the server can forward the data. C.The server converts the data to bits for transport across the medium. D.The server adds the source and destination IP address to each segment header to deliver the packets to the destination. E.The server adds the source and destination physical addresses to the packet header. 4.Which term describes a specific set of rules that determines the formatting of messages and the process of encapsulation used to forward data? A.segmentation B.protocol C.multiplexing D.Q o S E.reassembly 5.Which two are protocols associated with Layer 4 of the O S I model? (Choose two.)
