Characteristics of a Network & Access Method
In which type of network is there no dedicated server, with each node on the network being an equal resource for sharing and receiving information?
A. Client-server
B. Peer-to-peer
C. Windows Server 2016
D. Novell NetWare 6.x
B is the correct answer. A peer-to-peer network has no dedicated servers. There are no hierarchical differences between the workstations in the network; each workstation can decide which resources are shared on the network. In a peer-to-peer network, all workstations are clients and servers at the same time.
A, C, and D are incorrect. A is incorrect because this network type has a dedicated server. C and D are incorrect because Windows Server 2016 and Novell NetWare 6.x constitute the server portion of the client server network.
The physical layout of computers, cables, and other components on a network is known as what?
A. Segment
B. Backbone
C. Topology
D. Protocol
C is the correct answer. The topology is the physical layout of computers, cables, and other components on a network. Many networks are a combination of the various topologies.
A, B, and D are incorrect. A is incorrect because a segment is a part of a LAN that is separated by routers or bridges from the rest of the LAN. B is incorrect because a backbone is the main part of cabling that joins all of the segments together and handles the bulk of the network traffic. D is incorrect because a protocol is a set of rules governing the communication between PC’s; a protocol can be thought of as similar to a language.
What is the maximum distance of CAT 5 UTP cabling?
A. 100 meters
B. 185 meters
C. 250 meters
D. 500 meters
A is the correct answer. All twisted-pair cabling is limited to 100 meters.
B, C, and D are incorrect. B is incorrect because 185 meters is the maximum distance of thinnet cabling. C is incorrect because there is no cable type that has a 250-meter maximum distance. D is incorrect because 500 meter is the maximum distance of thicknet cabling.
You want to create a crossover cable to connect two systems directly together. Which wires would you have to switch at one end of the cable?
A. Wires 1 and 2 with wires 3 and 6
B. Wires 2 and 3 with wires 6 and 8
C. Wires 1 and 2 with wires 3 and 4
D. Wires 2 and 3 with wires 3 and 6
A is the correct answer. To create a crossover cable, you would switch wires 1 and 2 with wires 3 and 6 on one end of the cable.
B, C, and D are incorrect. These combinations are not used to create crossover cables.
What is the name given to languages that are used for network communication?
A. NIC
B. Segment
C. Protocol
D. Cable
C is the correct answer. A protocol is the network language used by two systems to communicate across the network.
A, B, and D are incorrect. A NIC is a network card, which is not a language—it is a network device. The segment is the term for a part of network cabling on one side of a router or bridge. The cable is not a language; it is the network medium used to carry the signals.
What is the Microsoft term for a peer-to-peer network?
A. Client-server
B. Domain
C. Workgroup
D. Active Directory
C is the correct answer. The Microsoft term for a peer-to-peer network is a workgroup environment. If you have not installed your Windows clients in a domain (client-server), then they are in a workgroup environment.
A, B, and D are incorrect. A is incorrect because a client-server network is the opposite of a peer-server network is the opposite of a peer-to-peer network; a client-server network uses a central server. B is incorrect because domain is the term for a Microsoft server-based environment. D is incorrect because Active Directory is the term for Microsoft’s implementation of a directory server.
Which topology has a layout in which every workstation or peripheral has a direct connection to every other workstation or peripheral on the network?
A. Bus
B. Star
C. Mesh
D. Ring
E. Wireless
C is the correct answer. A mesh topology is not very common in computer networking, but you have to know it for the exam. The mesh topology is seen more often with something like the nationwide telephone network. With a mesh topology, every workstation has a connection to every other component of the network.
A, B, D, and E are incorrect. A is incorrect because a bus topology uses one cable to connect multiple computers. B is incorrect because a star topology is made up of a central point or hub, with cables coming from the hub and extending to the PCs. D is incorrect because this topology resembles a circle or ring. E is incorrect because there is no physical cabling to represent the topology; it is represented by a bubble or cell.
You wish to install a 100BaseT network. What type of cabling will you use?
A. CAT 3 UTP
B. CAT 5 UTP
C. Thinnet
D. Fiber-optic
B is the correct answer. 100BaseT uses twisted-pair that runs at 100 Mbps. CAT 5 is the twisted-pair cabling type that runs at 100 Mbps.
A, C, and D are incorrect. A is incorrect because CAT 3 runs at 10 Mbps. C is incorrect because thinnet runs at 10 Mbps and is known as 10Base2. D is incorrect; although fiber optic can run at 100 Mbps, it is not used in 100BaseT.
Which network architecture uses single-mode fiber-optic cabling?
A. 1000BaseLX
B. 1000BaseSX
C. 1000BaseCX
D. 1000BaseTX
A is the correct answer. 1000BaseLX uses single-mode fiber-optic cabling.
B, C, and D are incorrect. 1000BaseSX uses multimode fiber-optic cabling, 1000BaseCX uses coaxial cabling, and 1000BaseTX uses CAT 5e or higher.
Which protocol used on the Internet gives each computer a unique address?
A. 802.11
B. TCP/IP
C. NetBEUI
D. DLC
B is the correct answer. TCP/IP is the protocol of the Internet, and each system is assigned a unique IP address.
A, C, and D are incorrect. 802.11 is the IEEE standard for wireless, NetBEUI was developed by IBM and used in Microsoft workgroup environments, and DLC is a protocol used to connect to printers.
A company has offices in Halifax and Toronto. Both networks are connected to allow the two locations to communicate. This is considered what type of network?
A. LAN
B. JAN
C. MAN
D. WAN
D is the correct answer. Two remote offices that are spread over geographic distances constitute a wide area network (WAN).
A, B, and C are incorrect. A is incorrect because it is the opposite of a WAN; a LAN is a network in a single geographic location. B is incorrect because there is no such thing in networking as a JAN. C is incorrect because this is a metropolitan area network.
You have four switches connected together with twisted-pair cabling. Systems connected to switch two cannot seem to communicate with the rest of the network. What could be the problem?
A. It is not using a straight-through cable to connect to the other switches.
B. It is using an LC connector to connect to the other switches.
C. It is using an ST connector to connect to the other switches.
D. It is not using a crossover to connect to the other switches.
D is the correct answer. When connecting similar devices, you should use a crossover cable, which switches the placement of the transmit and receive wires on one end of the cable to allow similar devices such as two switches to communicate.
A, B, and C are incorrect. LC and ST connectors are used with fiberoptic cabling; a straight-through cable would not be used to connect two switches together.
Fiber-optic cabling uses which types of connectors? (Choose two.)
A. SC
B. RJ-45
C. BNC
D. ST
A and D are the correct answers. Fiber-optic cabling uses a number of connector styles, two of which are the SC and ST connectors.
B and C are incorrect. RJ-45 is used by twisted-pair cabling, and BNC is used by thinnet.
Which type of cabling is used in a 10BaseFL network?
A. STP
B. CAT 3 UTP
C. Thinnet
D. Thicknet
Fiber-optic
E is the correct answer. 10BaseFL uses fiber-optic cabling. Remember to watch the characters at the end of the architecture name to determine what the cable type is—“FL” is for fiber link.
A, B, C, and D are incorrect. STP, thinnet, thicknet, and CAT 3 UTP are all cable types, but are not used in 10BaseFL.
Which of the following protocols is a non-routable protocol?
A. DLink
B. TCP/IP
C. NetBEUI
D. 802.11
C is the correct answer. NetBEUI is a non-routable protocol.
A, B, and D are incorrect. DLink is not a protocol; it is the manufacturer of network equipment such as home routers and switches. TCP/IP is a routable protocol, and 802.11 is the IEEE standard for wireless.
Which type of server is responsible for storing files for users on the network?
A. File and print server
B. Web server
C. Directory server
D. Application server
A is the correct answer. A file and print server is responsible for providing files and printers to users on the network.
B, C, and D are incorrect. They are each their own type of server. A web server will host websites; a directory server contains a central list of objects, such as user accounts on the network; and a application server runs a form of networking application, such as an e-mail or a database server program.
Which cable type sends the signal as pulses of light through a glass core?

Which Gigabit architecture uses multimode fiber cabling?
A. 1000BaseLX
B. 1000BaseSX
C. 1000BaseCX
D. 1000BaseTX
B is the correct answer. 1000BaseSX uses multimode fiber cabling. Remember that multimode cannot go as far as single mode, and also the “SX” in the architecture is for “short range”—multimode for short range; single mode for long range.
A, C, and D are incorrect. 1000BaseLX uses single-mode fiber, 1000BaseCX uses coaxial cable, and 1000BaseTX uses twisted-pair.
Which protocol was developed by IBM and used primarily in Microsoft workgroup environments?
A. NetBEUI
B. TCP/IP
C. IP
D. 802.11
A is the correct answer. NetBEUI was developed by IBM and used primarily in Microsoft workgroup environments.
B, C, and D are incorrect. TCP/IP is the protocol suite of the Internet, IP is the protocol within TCP/IP that handles logical addressing and routing, and 802.11 is the IEEE standard for wireless.
Which access method does 100BaseT use?
A. Baseband
B. CSMA/CD
C. CSMA/CA
D. Token passing
B is the correct answer. Carrier sense multiple access with collision detection (CSMA/CD) is the access method that 100BaseT uses. With CSMA/CD, a host will sense the wire to see if it is free; only if the wire is free of data will the host send data.
A, C, and D are incorrect. Baseband is not an access method. CSMA/CA and token passing are access methods, but are not used by 100BaseT.
Which topology has a centralized location in which all of the cables come together to a central point such that a failure at this point brings down the entire network?
A. Bus
B. Star
C. Mesh
D. Ring
Wireless
B is the correct answer. In a star topology, all computers are connected through one central hub or switch. A star topology actually comes from the days of the mainframe system. The mainframe system had a centralized point at which the terminals connected.
A, C, and D are incorrect. A is incorrect because a bus topology uses one cable to connect multiple computers. C is incorrect because the mesh network has every PC connected to every other PC and can resemble a spider’s web. D is incorrect because a ring topology resembles a circle or ring. E is incorrect because there is no physical cabling to represent the topology; it is represented by a bubble or cell.
Which cable type is immune to outside interference and crosstalk?
A. Thinnet
B. Thicknet
C. Twisted pair
D. Fiber-optic
D is the correct answer. Fiber-optic cabling is immune to outside interference and crosstalk.
