Which of the following geographic network types is typically managed by a city as a public utility? -
✔✔Metropolitan area network (MAN)
You've implemented a network where each device provides all other devices on the network with access
to shared files.
Which type of network do you have? - ✔✔Peer-to-peer
You have a network that uses a logical bus topology. How do messages travel through the network? -
✔✔Messages are broadcast to all devices connected to the network.
You have a network that uses a logical ring topology. How do messages travel through the network? -

Transport You're installing network wiring for a new Ethernet network at your company's main office building. The project specifications call for Cat 5e UTP network cabling and RJ45 wall jacks. Near the end of the project, you run out of wire before the last few runs are complete. You have a spool of Cat 3 network cable in storage. Upon closer inspection, it appears very similar to the Cat 5e wiring. To finish the project, should you use the Cat 3 cabling as a substitute for the Cat 5e cabling? - ✔✔No. Cat 5e cabling has more twists per inch than Cat 3 cabling, reducing crosstalk and supporting higher data rates. Which of the following cable types often includes a solid plastic core that keeps the twisted pairs separated? - ✔✔Cat 6 You're adding new wires in your building for some new offices. The building has a false ceiling that holds the lights and provides an air path for heating and air conditioning. You'd like to run your Ethernet cables in this area. Which type of cable must you use? - ✔✔Plenum-rated cable Why might you use an RJ11 connector? - ✔✔You want to connect your computer to the internet with a DSL modem. Which of the following connectors is used with Ethernet 100BaseTX networks? - ✔✔RJ Which of the following connector types would you most likely use to connect to a T1 WAN service? - ✔✔RJ48c You're working with an older 10Base2 Ethernet network. Which of the following connector types will you MOST LIKELY encounter? - ✔✔BNC Which of the following are characteristics of a coaxial network cable? (Select two.) - ✔✔It uses two concentric metallic conductors.

They can be used with multi-mode fiber optic cables. Multi-mode fiber is designed to operate at which of the following wavelengths? - ✔✔850 nm and 1300 nm Which of the following connectors usually require polishing as part of the assembly process? (Select two.) - ✔✔ST SC Which of the following is true about single-mode fiber optic network cabling? - ✔✔Its central core is smaller than the standard multi-mode fiber optic cabling core. Which type of optical fiber is normally used to connect two buildings that are several kilometers apart? - ✔✔Single-mode fiber You've decided to implement Gigabit Ethernet on your network; each switch port is connected to a single device. Following the installation, you find one device connected to a switch that's only running at 100 Mbps. Which of the following is MOST LIKELY the cause? - ✔✔Crosstalk You have a cable internet connection at home. The installer had connected the router near the outside wall of your house with RG6 cable. You move the cable router a distance of 50 meters using RG8 cables and special connector adapters. Which condition are you MOST LIKELY to experience? - ✔✔Echo While viewing the status of interfaces on a Cisco switch, you see an abnormally large number of CRC errors on one interface. This interface is connected to a user's workstation that is located in a cubicle on the second floor. What could cause this to happen? - ✔✔A strong EMI emitter near the cable connected to that interface.

You need to replace a fiber optic cable that's connecting two switches together. You inspect the existing cable and determine that it uses LC connectors. You also notice that the cable's ferrule has a slight slant to it. Which polish grade should you use to replace the existing cable? - ✔✔Angled Physical Contact polish You're building a new network for a small financial services startup company. Security is paramount, so each organization within the company will have its own network segment separated by a router. However, funds are limited, and you've been asked to keep costs to a minimum. You've acquired a used fiber optic switch, and you want to use it to create a fiber optic backbone that interconnects all of the routers. You've purchased several used single-mode GBIC modules on eBay that you'll install on each router to allow them to connect to the switch. Both the switch and the GBIC modules use MTRJ connectors. You connect each module to the switch with 1-meter multimode patch cables. Will this implementation work? - ✔✔No. You shouldn't use multi-mode patch cables with single-mode GBIC modules.

You've purchased several used 1-meter, multi-mode patch cables from Amazon. But when they arrived, you noticed that they use LC connectors. Fortunately, with some force, you found that you're able to get the LC connectors on the cables to lock into the MTRJ connectors on the GBIC modules and on the switch. Will this implementa - ✔✔No. You should purchase patch cables that use MTRJ connectors. You want to measure the voltage, amps, and ohms of various devices. Which tool should you use? - ✔✔Multimeter You're working with an existing fiber optic installation in your building. You want to know the length of each cable that runs through the walls. Which tool should you use? - ✔✔OTDR
