2026/2027 AND HIGH YIELD PRACTICE QUESTIONS
COMPLETE ACCURATE EXAM APPROVED QUESTIONS AND
CORRECT VERIFIED SOLUTIONS (100% CORRECT VERIFIED
ANSWERS) CURRENTLY UPDATED VERSION 2026 EDITION
network cable. copper wire. electrical signal.
four pairs. color-coded. each wire insulated. pairs twisted at different
rates.
electrical signaling suffers attenuation; max recommended distance
100m/328ft.
unshielded twisted pair (UTP)
,network cable. copper wire. electrical signal.
shielding for pairs or whole cable reduces interference. 10G+ ethernet.
screening/shielding must be bonded to connector.
shielded twisted pair (STP)
screened cable (ScTP); foil shield around all pairs.
shielded/foiled (S/FTP); braided outer screen and foil-shielded pairs.
twisted pair cabling data rates and ethernet standards.
m; higher cat indicates higher data rates. specification printed on cable
jacket.
defined in TIA/EIA-568-C commercial building telecommunications
cabling standards.
cat specification
cat5; legacy. 100 Mbps/100m.
cat5e; 1 Gbps/100m.
cat6; 1 Gbps/100m or 10Gbps/55m.
cat6a; 10Gbps/100m.
,connectors that terminate twisted pair cabling for ethernet.
m; the RJ45 port establishes the physical connection to the cable.
RJ45 or 8P8C (eight-position/eight-contact) connectors
use same termination within a network.
m; defined in the ANSI/TIA/EIA 568 Commercial Building
Telecommunications Standards.
T568A/T568B
RJ45 connectors. 5m max length. used for computer to wall port.
patch cord
behind wall port; runs through wall/ceiling to patch panel.
permanent cable
, tool for stripping cable jacket or wire insulation.
m; must be done without insulation damage. set stripper to correct
diameter, rotate once or twice.
cable stripper
for holding wires.
punchdown blocks or insulation displacement connectors (IDC)
use for placing twisted-pair cables to punchdown blocks.
m; untwist the pairs; untwist no more than ½" (13 mm). place into IDC in
termination order (T568A or T568B). use tool to press wire into terminals.
punchdown tool
