Which two devices are considered OSI Layer 1 devices? (Choose two.) • hubs • routers • bridges • switches • repeaters 3. What device is used to connect hosts to an Ethernet LAN and requires a straight-through UTP cable between the hosts and this device? • NIC • router • switch • server 4. What is the most common type of cabling used in LANs? • STP • UTP • coax • fiber 5. In which situations would a crossover cable be used to connect devices in a network? (Choose two.) • switch to PC • switch to hub • switch to router • switch to server • switch to switch 6.  Refer to the exhibit. How many collision domains exist in the network?
• 1 • 2 • 4 • 7 • 8 7. What type of cable would be used to make the connection between the console port of a router and a workstation? • crossover • rollover • straight-through • patch 8.  Which function is a unique responsibility of the DCE devices shown in the exhibit?
• transmission of data • reception of data • clocking for the synchronous link • noise cancellation in transmitted data 9. Which address does a bridge use to make filtering and switching decisions? • source MAC • source IP • destination MAC • destination IP • network IP address 10. What is characteristic of how a hub operates? • A hub selectively drops packets that represent potential security risks. • A hub forwards data out all interfaces except the inbound interface. • A hub dynamically learns the interfaces to which all devices are attached. • At start up, a hub queries the devices on all interfaces in order to learn the MAC addresses of the attached devices. • A hub transmits a frame to a specific interface based on the destination MAC address. 11. Users with systems that are attached to a hub are complaining about poor response time. What device could replace the hub and provide immediate response time improvement? • router • switch • bridge • repeater 12. Which of the following are benefits of peer-to-peer networks? (Choose three.) • centralized security • easy to create • very scalable • no centralized equipment required • centralized administrator not required • centralized control of assets 13. Which statement is accurate about a WAN link? • The link transmits data serially. • The link uses a maximum distance of 100 meters. • The link uses the same transmission rate as all other WAN links use. • The link uses the same standardized connector style that is used for all WAN technologies. 14.  Which items in the exhibit are DTE devices?
• A and B • B and C • C and D • A and D • A, B, C, and D 15. At which layer of the OSI model does the MAC address of a NIC reside? • physical • application • network • transport • data link • session 16.  Refer to the exhibit. A technician measured the lengths of the CAT 5e structured cable runs in the exhibit. How should the technician evaluate the cabling shown in the diagram to the network administrator?
• All cabling to work areas are within specifications. • Station A and B may experience intermittent problems because the length exceeds the recommended standard. • Station B may experience intermittent problems because the length exceeds the recommended standard. • Station C may experience intermittent network connectivity because the length is less than the recommended standard. • Station A and B will have intermittent problems because the length exceeds the recommended standard. • Station C will not have network connectivity because the length is less than the recommended standard. 17. Which statement describes a typical use of Gigabit Ethernet? • to provide high-speed desktop connectivity for average users • to provide connectivity to low to medium volume applications • to provide medium volume connectivity to workgroup servers • to provide high-speed connectivity for backbones and cross connects 18.  The ends of a UTP cable are shown in the exhibit. Which cable configuration is shown?
• crossover • rollover • reversed-pair • straight-through • split-pair • console 19.  The ends of a UTP cable are shown in the exhibit. Which cable configuration is shown?
• console • crossover • rollover • reversed-pair • split-pair • straight-through 20. Which of the following are benefits of a wireless network? (Choose two.) • higher data speeds • better security • mobility • less expensive NIC cards • no need to run cables to hosts |
