Which of the following is true regarding the use of Ethernet in this LAN? a. Only the devices that use cables are using Ethernet. b. Only the devices that use wireless are using Ethernet. c. Both the devices using cables and those using wireless are us ing Ethernet. d. None of the devices are using Ethernet. - ANSWER Only the de vices that use cables are using Ethernet. Which of the following Ethernet standards defines Gigabi t Ethernet over UTP cabling? a. 10GBASE-T b. 100BASE-T c. 1000BASE-T d. None of the other answers is correct. - ANSWER 1000BASD-T Which of the following is true about Ethernet crossover cables for Fast Ethernet? a. Pins 1 and 2 are reversed on the other end of the cable. b. Pins 1 and 2 on one end of the cable connect to pins 3 and 6 on the other end of the cable. c. Pins 1 and 2 on one end of the cable connect to pins 3 and 4 on the other end of the cable. d. The cable can be up to 1000 meters long to cross over between build ings. e. None of the other answers is correct. - ANSWER Pins 1 an d 2 on one end of the cable connect to pins 3 and 6 on the other end of the cable. Each answer lists two types of devices used in a 100BASE-T network. If these d evices were connected with UTP Ethernet cables, which pairs of devices would requ ire a straight-through cable? (Choose three answers.) a. PC and router b. PC and switch c. Hub and switch d. Router and hub e. Wireless access point (Ethernet port) and switch - ANSWER PC and switch, Router and hub, Wireless access point (Ethernet port) and switch Which of the following fields in the HDLC header used by Cisc o routers does Cisco add, beyond the ISO standard HDLC? a. Flag b. Type c. Address d. FCS - ANSWER Type Two routers, R1 and R2, connect using an Ethernet over MPLS service. T he service provides point- to-point service between these two routers only, as a Layer 2 Ethernet service. Which of the following are the most likely to be true about this WAN? (Ch oose two answers.) a. R1 will connect to a physical Ethernet link, with the other end of the cable connected to R2. b. R1 will connect to a physical Ethernet link, with the other end of the cable connected to a device at the WAN service provider point of presence. c. R1 will forward data-link frames to R2 using an HDLC header /trailer. d. R1 will forward data-link frames to R2 using an Ethern et header/trailer. - ANSWER R1 will connect to a physical Ethernet link, with the other end of the cable c nected to a device at the WAN service provider point of presence. R1 will forward data-link frames to R2 using an Ethernet h eader/trailer. Imagine a network with two routers that are connected with a poin t-to-point HDLC serial link. Each router has an Ethernet, with PC1 sharing the Ethernet with Rou ter1 and PC2 sharing the Ethernet with Router2. When PC1 sends data to PC2, which of the followin g is true? a. Router1 strips the Ethernet header and trailer off the f rame received from PC1, never to be used again. b. Router1 encapsulates the Ethernet frame inside an HDLC header an d sends the frame to Router2, which extracts the Ethernet frame for forwarding to PC2. c. Router1 strips the Ethernet header and trailer off the frame received from PC1, which is exactly re-created by Router2 before forwarding data to PC2. d. Router1 removes the Ethernet, IP, and TCP headers and rebuilds the appropriate headers before forwarding the packet to Router2. - ANSWER Router1 strips the Ethernet header and
