3.1 CCNA 1 - Module 5

1	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
2	What is the most common type of cabling used in LANs? STP UTP coax fiber
3	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
4	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.
5	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
6	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.
7	At which layer of the OSI model does the MAC address of a NIC reside? physical application network transport data link session
8	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
9	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
10	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
11	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
12	Which two devices are considered OSI Layer 1 devices? (Choose two.) hubs routers bridges switches repeaters
13	Refer to the exhibit. How many collision domains exist in the network? 1 2 4 7 8
14	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
15	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.
16	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
17	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
18	Which address does a bridge use to make filtering and switching decisions? source MAC source IP destination MAC destination IP network IP address
19	Refer to the exhibit. What is the appropriate cable to use at each of the numbered network connections? 1-crossover; 2-straight-through; 3-crossover; 4-straight-through 1-straight-through; 2-crossover; 3-straight-through; 4-straight-through 1-straight-through; 2-crossover; 3-crossover; 4-straight-through 1-rollover; 2-crossover; 3-straight-through; 4-straight-through 1-rollover; 2-straight-through; 3-straight-through; 4-straight-through
20	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
