This is the study guide for my midterm. It is 60 multiple choice questions. I can even give a 20 dollar tip if i can get it done by saturday. You have helped me before and were a Huge help! Help me again and I will make it worth your while!
Let me know, as I have to upload the rest of the questions somehow.
1. Which of the following best describes the function of the network medium?
a. It provides the physical connection between networked computers.
b. It provides the protocol used to transmit data between end systems.
c. It passes data between two routers.
d. It processes electrical or light signals and converts them to data.
____ 2. What type of network is typically confined to a small geographic area, such as a single room, floor, or building?
____ 3. What type of network connects local area networks (LANs) in distant locations?
____ 4. Which type of network typically uses point-to-point links to connect networks, as shown in the following illustration?
____ 5. Which of the following organizations developed the Open Systems Interconnection (OSI) model?
a. Telecommunication Standardization Sector of the International Telecommunication Union (ITU-T)
b. Comité Consultatif International Télégraphique et Téléphonique (CCITT)
c. American National Standards Institute (ANSI)
d. Institute of Electrical and Electronics Engineers (IEEE)
e. International Organization for Standardization (ISO)
____ 6. Which of the following statements describes the process of data encapsulation?
a. Protocols perform data encapsulation when they add specific codes within the datagram that are used for error checking.
b. Protocols perform data encapsulation when they embed protocol identification information within the datagram.
c. Protocols within the stack perform data encapsulation by adding a header—and, in some cases, a footer—to the information received from an upper-layer protocol.
d. Data encapsulation is the process of including only the user data in a packet.
____ 7. You have been hired to design a small network for a private company. The network has 10 users who all need to share data and resources. The network you choose should support baseband signaling and a star topology and should use a collision-free Media Access Control (MAC) method. Based on this information, identify the appropriate data-link layer protocol and the channel access method that should be used by this protocol.
b. Token Ring
d. Internet Protocol (IP)
____ 8. Identify the layer of the Open Systems Interconnection (OSI) model that controls the transmission, reception, and addressing of frames. Also identify the channel access method that Ethernet uses.
a. Physical layer; Carrier Sense Multiple Access with Collision Detection (CSMA/CD)
b. Data-link layer; token passing
c. Physical layer; token passing
d. Data-link layer; Carrier Sense Multiple Access with Collision Detection (CSMA/CD)
____ 9. You are a network administrator designing a local area network (LAN). You need to determine the type of cabling and network architecture to implement in your network. Which layers of the Open Systems Interconnection (OSI) model apply to cabling and network architecture elements?
a. Data-link and network layers
b. Network and transport layers
c. Transport and application layers
d. Physical and data-link layers
____ 10. What layer of the Open Systems Interconnection (OSI) model defines the medium, network interfaces, connecting hardware, and signaling methods used on a network?
____ 11. What layer of the Open Systems Interconnection (OSI) model is responsible for the logical addressing of end systems and the routing of datagrams on a network?
____ 12. What layer of the Open Systems Interconnection (OSI) model is responsible for the translation and formatting of information?
____ 13. Which type of cable and connector is used to attach a television set to a cable television (CATV) network?
a. A fiber-optic cable and a Straight Tip (ST) connector
b. A coaxial cable and a Bayonet-Neill-Concelman (BNC) connector
c. A twisted-pair cable and an RJ-45 connector
d. A coaxial cable and an F-type connector
e. An AUI cable and a vampire tap connector
____ 14. Which cable type is used for thick Ethernet network segments?
____ 15. Which cable type is typically configured in a star topology, uses eight copper conductors arranged in four pairs, and uses RJ-45 connectors?
____ 16. What purpose do the twists serve in twisted-pair cabling?
a. They prevent collisions.
b. They completely eliminate crosstalk from adjacent pairs and electromagnetic interference (EMI).
c. They prevent crosstalk from adjacent pairs and limit the effects that EMI has on the signal being carried over the cable.
d. They extend the bend radius allowance of the cable.
____ 17. What type of tool do you use to add connectors such as RJ-45 and RJ-11 to twisted-pair cabling?
a. A crimper
b. A splicer
c. A pigt
