Progression: Field Tech IV - V Conventional Questions and Answers 2023/2024 (100% Pass ). What components are common to all computer systems? (Check all that apply.) - Processor Memory Storage I/O What does I/O stand for? - Input / Output A NIC is a device used for: - Signaling A sound card is what general type of computer component? - Input/output Which of the following is managed by the OS? - Keyboard input Screen display File I/O Peripheral control The primary purpose of a device driver is to control hardware under the supervision of the OS. True or False? - True Which of the following network topologies forms a closed loop? - Ring topology Which of the following network topologies connects devices to a shared straight-line cable? - Bus topology M1L5 When is UTP cable preferred over STP? - When there is little electrical interference Which connector type is used with Thinnet coaxial cable? - BNC Which of the following cable types uses a T-connector to connect each NIC to the cable? - Thinnet Which of the following cable types can transmit data farthest? - Fiber optic How are bits represented on fiber optic cable? - Pulses (on/off) of light Which of the following are the two primary types of light sources in fiber optic cables? - Laser diode and LED What is the main advantage of star topology? - Ease of management Which of the following would not be used in a typical star topology? - Thinnet How many wire pairs can be terminated on a 66 block? - 25 or 50 What makes a crossover cable different from a patch cord? - A crossover cable uses the 568A pattern on one jack, and the 568B pattern on the other. A patch cord uses the same pinout pattern on both jacks. What is the key reason that smart LAN administrators demand well-made cable connections? - Bad cable connections degrade a network's performance. What is the main advantage of using balanced signaling on a serial cable? - The cable can be longer because balanced signaling is less vulnerable to interference. What term describes the number of wave crests that pass a fixed point during a particular period of time? - Frequency In data networking, this term is defined as "Signals may flow in either direction, but not simultaneously". - Half-duplex Two CPUs have the same size data bus. Which one will process data faster? - The one with a higher clock speed This unique ID number is coordinated by the Institute of Electrical and Electronics Engineers and is used by only one network interface card anywhere in the world. - Media access control address (MAC) Which is a network management and utility software that is typically used by network administrators and information systems personnel when the network is unused or lightly used, often in the middle of the night? - Backup and recovery utilities Which of the following is also called "Thicknet" or "yellow wire" and includes two layers of foil shielding as well as an additional copper mesh shield? - 10Base5 cable According to 10BaseT wiring rules, what is the maximum segment length without a repeater? - 100m When light travels through a fiber-optic cable, the change in refractive index causes the light to refract off which of the following? - The boundary between the core and the cladding Which of the following requires a laser transmitter? - Single-mode fiber In what part of a building would you typically find punch-down blocks? - Wiring closet Which OSI model layers are concerned primarily with applications? - The top three Which layers are primarily concerned with moving raw data? - The lower four Which of the following is the primary purpose of a Physical Layer protocol? - Transmit bits across a physical link Which of the following will not occur at the Physical Layer? - Rerouting of information Which of the following is the primary purpose of a Data Link Layer protocol? - Transmit frames across a physical link Which of the following hardware devices builds a frame? - NIC Frame headers and packet headers contain addresses.

What is the fourth? - Segmentation Which type of address is unique anywhere in the world? - NIC address Which layer of the OSI protocol stack handles frames? - Data Link Which of the following best represents a logical address? - IPv6 In data networking, ________ describes the characteristics of a transmission link, such as throughput, setup time, or accuracy. - Quality of service (QoS) Transport layer processes work with transmission channels using multiplexing and ___________ techniques. - Parallelization Which of the following protocols is commonly used in the Session Layer? - Advanced Program-to-Program Communications (APPC) What is the binary equivalent to the decimal number "14"? - Data security, data compression, and ________ are the three main services that the Presentation Layer provides. - Data representation Which of the following is an example of a Transport Layer protocol? - Transmission Control Protocol (TCP) Ethernet operates at all speeds except which of the following? - 16 Kbps
