DHY WGU Fundamentals of Interconnecting Network Devices WGU- C246. Exam Review Questions and answers, VERIFIED. What do you call data that includes the Layer 4 protocol header, and data given to Layer 4 by the upper layers, not including any headers and trailers from Layers 1 to 3? (Choose two answers.) - -Segment L4PDU The terms packet and L3PDU refer to the header plus data encapsulated by Layer 3. Frame and L2PDU refer to the header (and trailer), plus the data encapsulated by Layer 2. Segment and L4PDU refer to header and data encapsulated by the transport layer protocol. Which of the following functions is performed by both TCP and UDP? - -Multiplexing using port numbers TCP, not UDP, performs windowing, error recovery, and ordered data transfer. Neither performs routing or encryption. Which of the following header fields identify which TCP/IP application gets data received by the computer? (Choose two answers.) - -TCP Port Number UDP Port Number Many headers include a field that identifies the next header that follows inside a message. Ethernet uses the Ethernet Type field, and the IP header uses the Protocol field. The TCP and UDP headers identify the application that should receive the data that follows the TCP or UDP header by using the port number f ield in the TCP and UDP headers, respectively. Which of the following are typical functions of TCP? (Choose four answers.) - -Flow control (windowing) Error recovery Multiplexing using port numbers Ordered data transfer Fred opens a web browser and connects to the website. Which of the following are typically true about what happens between Fred's web browser and the web server? (Choose two answers.) - -Messages flowing to the client typically use a source TCP port number of 80. Messages flowing to the server typically use TCP. Web traffic uses TCP as the transport protocol, with HTTP as the application protocol. As a result, the web server typically uses well-known TCP port 80, which is the well-known port for HTTP traffic. Messages flowing to the web server would have a destination TCP port of 80, and messages flowing from the server would have a source TCP port of 80. In the URI
