ERRATA SHEET: CheatExams CompTIA Network+ Prep for N10-002 Exam Tere Prasse, A+, CST, Network+, i-Net+, CIWA, CWPA, MCSA, MCSE (NT/W2K) Question 43: Correct answer is C. Bridges use "bridging tables." Bridges work at the data link layer of the OSI model, and MAC addresses are at the data link layer as well. Bridging tables are based on MAC addresses. Routers use "routing tables." Routers work at the network layer of the OSI model, and IP (or IPX) addresses are at the network layer as well. Routing tables (presuming a TCP/IP network) are based on IP addresses. Question 115: The interface card which intends to depict a modem (second from right) has RJ-45 rather than RJ-11 connectors depicted. Question 160: The figure shows "Windows 98 IP Configuration" at the top which is obviously in error since Windows 98 uses WINIPCFG and has a different output. Question 195: Correct answers are C & D. A hub passes all traffic, a router (on a TCP/IP network) uses IP for addressing. Bridges and Layer 2 switches both operate at the data link layer, and use MAC addresses which are also associated with the data link layer. Question 225: Correct answer is D. Repeaters make direct connections between two devices; switches are far more sophisticated than both hubs and repeaters.
