QUESTIONS AND CORRECT ANSWERS | BRAND NEW VERSION!
Question 1
What term describes the number of wave crests that pass a fixed point during a particular period
of time?
A) Amplitude
B) Frequency
C) Wavelength
D) Phase
E) Period
Correct Answer: B) Frequency
Rationale: Frequency is a fundamental property of waves, measured in Hertz (Hz), which
represents cycles per second. In telecommunications, higher frequencies allow for greater
data transmission rates but often have shorter propagation ranges. It is inversely
proportional to wavelength.
Question 2
In data networking, this term is defined as "Signals may flow in either direction, but not
simultaneously."
A) Simplex
B) Full-duplex
C) Half-duplex
) Multiplex
E) Baseband
Correct Answer: C) Half-duplex
Rationale: Half-duplex transmission allows two-way communication, but only one station
can transmit at a time. This is comparable to a walkie-talkie or an informal conversation
where participants take turns. In contrast, full-duplex allows simultaneous two-way traffic,
while simplex is strictly one-way.
Question 3
Two CPUs have the same size data bus. Which one will process data faster?
A) The one with the larger cache
B) The one with more cores
C) The one with a higher clock speed
D) The one with a smaller instruction set
E) The one using RISC architecture
Correct Answer: C) The one with a higher clock speed
Rationale: Clock speed, measured in GHz, determines how many cycles a CPU can perform
per second. If the data bus size is identical (meaning they can move the same amount of
data per cycle), the processor that completes more cycles per second will process data at a
faster rate.

Question 4
This unique ID number is coordinated by the IEEE and is used by only one network interface
card (NIC) anywhere in the world.
A) IP Address
B) Logical Address
C) Port Number
D) Media access control address (MAC)
E) Serial Number
Correct Answer: D) Media access control address (MAC)
Rationale: The MAC address is a 48-bit hardware address burned into the NIC. It consists
of an Organizationally Unique Identifier (OUI) assigned to the manufacturer and a specific
serial number. Because it is globally unique, it operates at the Data Link Layer (Layer 2) to
identify devices on a local segment.
Question 5
Which is a network management and utility software that is typically used by network
administrators when the network is unused or lightly used, often in the middle of the night?
A) Simple Network Management Protocol (SNMP)
B) Backup and recovery utilities
C) Intrusion Detection Systems (IDS)
D) Protocol Analyzers
E) Network Baselines
Correct Answer: B) Backup and recovery utilities
Rationale: Backup and recovery processes are resource-intensive and can consume
significant bandwidth, potentially slowing down production traffic. Therefore, these
utilities are scheduled during "off-peak" hours to ensure data integrity without impacting
user performance.
Question 6
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?
A) 10Base2
B) 10BaseT
C) 100BaseFX
D) 10Base5 cable
E) RG-59
Correct Answer: D) 10Base5 cable
Rationale: 10Base5, or Thicknet, was the original Ethernet cabling. It used a thick, shielded
coaxial cable (roughly 0.5 inches in diameter). The extensive shielding allowed for a
, 3
maximum segment length of 500 meters, which was much longer than the later 10Base2
(Thinnet) or 10BaseT (Twisted Pair).
Question 7
According to 10BaseT wiring rules, what is the maximum segment length without a repeater?
A) 50 m
B) 100 m
C) 185 m
D) 500 m
E) 2,000 m
Correct Answer: B) 100 m
Rationale: The 100-meter limit for 10BaseT (and most subsequent twisted-pair standards
like 100BaseTX and 1000BaseT) is based on signal attenuation and timing requirements for
collision detection. To extend the network beyond 100 meters, a repeater, hub, or switch
must be used to regenerate the signal.
Question 8
When light travels through a fiber-optic cable, the change in refractive index causes the light to
refract off which of the following?
A) The outer jacket
B) The Kevlar strength members
C) The buffer coating
D) The boundary between the core and the cladding
E) The light source itself
Correct Answer: D) The boundary between the core and the cladding
Rationale: Fiber optics rely on "Total Internal Reflection." The core has a higher refractive
index than the cladding. When light hits the boundary between the two at a specific angle,
it reflects back into the core rather than passing through, allowing the signal to travel long
distances with minimal loss.
Question 9
Which of the following requires a laser transmitter for signaling?
A) Multi-mode fiber
B) Category 6A UTP
C) Single-mode fiber
D) 10Base2 Coax
E) RG-6
Correct Answer: C) Single-mode fiber
Rationale: Single-mode fiber (SMF) has a very small core (typically 8–10 microns) that
allows only one mode of light to propagate. Because of this precision, it requires a coherent
, 4
light source like a laser. Multi-mode fiber (MMF) has a larger core and typically uses
cheaper LED light sources.
Question 10
In what part of a building would you typically find punch-down blocks (like 66-blocks or 110-
blocks)?
A) Data Center
B) Reception Area
C) Wiring closet
D) Server Room
E) HVAC Room
Correct Answer: C) Wiring closet
Rationale: A wiring closet, or Telecommunications Closet (TC), is the central point where
horizontal cabling from work areas terminates. Punch-down blocks are used here to cross-
connect the internal building wiring to network switches or PBX phone systems.
Question 11
Encapsulation, decapsulation, and reassembly are three of the four basic techniques used when
different layers work together. What is the fourth?
A) Compression
B) Encryption
C) Segmentation
D) Multiplexing
E) Modulation
Correct Answer: C) Segmentation
Rationale: Segmentation is the process of breaking down large data streams into smaller,
manageable pieces (segments) at the Transport Layer. This allows for more efficient
transmission and enables the network to recover if a single piece of data is lost during
transit.
Question 12
Which type of address is unique anywhere in the world and serves as a hardware identifier?
A) IP address
B) Port address
C) NIC address
D) Subnet mask
E) Gateway address
Correct Answer: C) NIC address
Rationale: Also known as the MAC address or physical address, the NIC address is assigned
by the manufacturer and is unique worldwide. While IP addresses are logical and can
change based on the network, the NIC address is permanent to the hardware.
