FIELD TECH 2026 CORE EXAM TEST QUESTIONS AND
ANSWERS GUARANTEE A+
✔✔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. True or False? - ✔✔True
✔✔Which of the following is an example of a Network Layer protocol? - ✔✔IP
✔✔The Network Layer is to packets as the Data Link Layer is to: - ✔✔Frames
✔✔Which of the following is the primary purpose of a Transport Layer protocol? -
✔✔Transmit messages from process to process
✔✔The Transport Layer is not concerned with which of the following? - ✔✔None of the
above
✔✔Which layer uses port numbers for communication? - ✔✔Transport Layer
✔✔The Session Layer is concerned with which of the following? - ✔✔Managing dialog
