3.1 CCNA 1 - Module 3

1	What factors should be considered when selecting the appropriate cable for connecting a PC to a network? (Choose two.) type of system bus motherboard model distance of cable run speed of transmission computer manufacturer
2	What are two advantages of using UTP cable in a networking environment? (Choose two.) is stiffer than STP is less expensive than fiber is easier to install than coaxial provides longer distances than coaxial provides is less susceptible to outside noise sources than fiber is
3	A company is converting a cabled LAN to a wireless Ethernet LAN. What must be changed on every host on the network? No changes are required. Each host will require a new IP address. Each host will require an appropriate NIC or adapter. Each host will require that the operating system be upgraded.
4	What is the difference between a wireless NIC and an Ethernet NIC? The Ethernet NIC operates at 100 Mbps, whereas a wireless NIC operates at 10 Mbps. The Ethernet NIC uses a PCI expansion slot, and a wireless NIC cannot use an expansion slot. The wireless NIC uses CSMA/CA, whereas a Ethernet NIC uses token passing as an access method. The wireless NIC associates to an access point, and an Ethernet NIC attaches to a hub or switch using a cable. The Ethernet NIC attaches to a hub or a switch using only fiber cabling, and a wireless NIC attaches to a wireless antenna using air as a network medium.
5	Select the characteristics specified by 10BaseT. (Choose three.) twisted pair cable T style connectors baseband transmission 10 gigabits per second data rate 10 megabits per second data rate decimal encoded data transmission
6	What type of cable is used to make an Ethernet connection between a host and a LAN switch? console rollover crossover straight-through
7	Which wireless standard operates in the 5 GHZ transmission range and is capable of 54 Mbps of data throughput? 802.11 802.11a 802.11b 802.11g
8	Which of the following are used for data communication signals? (Choose three.) light patterns electrical voltages controlled air pulses mixed media impulses magnetized fluid wave modulated electromagnetic waves
9	Which cable connectors are used to connect a cable from a router's console port to a PC? (Choose two.) RJ-11 RJ-12 RJ-45 DB-8 DB-9 DB-10
10	Refer to the exhibit. What type of cable connects the two routers together without any intermediary device? console rollover crossover straight-through
11	When is a straight-through cable used in a network? when configuring a router when connecting a host to a host when connecting a switch to a router when connecting one switch to another switch
12	What does UTP cable rely on to reduce signal degradation caused by EMI and RFI? shielding magnetism cancellation insulation properly grounded connections RJ-45 connectors
13	What are two advantages of using fiber-optic cabling instead of UTP? (Choose two.) lower cost easer to install allows longer distances less effected by external signals easier to terminate the cable ends
14	Which Ethernet implementation requires the signal on the media to be boosted at a maximum distance of 100 meters? 10BASE2 10BASE5 100BASE-T 100BASE-FX 1000BASE-CX
15	Refer to the exhibit. Which answer correctly identifies the pinout of the UTP cables labeled Cable A, Cable B, and Cable C? A=straight, B=rollover, C=crossover A=rollover, B=crossover, C=straight A=crossover, B=straight, C=straight A=crossover, B=straight, C=rollover A=straight, B=crossover, C=rollover A=rollover, B=straight, C=crossover
