EXAM QUESTIONS AND CORRECT VERIFIED ANSWERS | ALREADY
GRADED A+
1. A structured cabling technician is preparing to install a new horizontal
cabling system in a commercial office where work-area outlets,
telecommunications rooms, pathways, and patching equipment have
already been identified on the drawings. Before pulling any cable, which
activity is most important for establishing a compliant installation
approach?
A. Begin pulling cable from the nearest telecommunications room
B. Confirm the approved drawings, cable types, pathways, spaces, labeling
requirements, and applicable installation standards
C. Terminate all patch-panel positions before verifying cable routes
D. Select cable lengths based only on the distance shown between
workstations
Answer: B
2. During installation of balanced twisted-pair cable, a technician removes
more of the cable jacket than necessary before terminating the conductors
on an IDC. Why should excessive untwisting of the pairs be avoided?
A. It can increase electromagnetic coupling and negatively affect
transmission performance
B. It makes the cable physically stronger
C. It reduces the cable's conductor resistance
D. It prevents the connector from being inserted into the patch panel
Answer: A
3. A technician is terminating Category-rated twisted-pair cable on a modular
jack and discovers that the conductor color sequence on the existing
installation differs from the sequence shown on the new outlet instructions.
pg. 1
, What should the technician do?
A. Use whichever sequence produces continuity
B. Reverse the transmit and receive pairs
C. Follow the approved wiring scheme consistently and maintain the same
pinout at both ends
D. Select conductors based on their physical position inside the cable
Answer: C
4. A structured cabling pathway has been installed above a suspended ceiling,
but the cable tray is already heavily loaded with power conductors and
other communications cables. What should the technician do before adding
additional structured cabling?
A. Place the new cable directly on top of the existing cables
B. Increase pulling tension so the cable occupies less space
C. Remove the cable jacket to reduce cable diameter
D. Verify pathway capacity and separation requirements and obtain an
appropriate installation solution if capacity is insufficient
Answer: D
5. A technician is installing a balanced copper cable in a telecommunications
room and needs to maintain the cable's performance characteristics
through the termination. Which practice is most appropriate?
A. Maintain pair geometry and minimize untwisting and deformation near
the termination
B. Flatten the cable aggressively so it fits the patch panel
C. Separate all conductors several inches before termination
D. Remove more insulation than necessary to simplify termination
Answer: A
6. A cable installer is pulling multiple twisted-pair cables through a pathway
and notices that the cable bundle is becoming difficult to pull. Which action
is most appropriate?
A. Increase pulling force until the cable moves
pg. 2
, B. Stop and determine whether pathway fill, bends, tension, or installation
technique is causing the resistance
C. Remove the cable jackets before pulling
D. Tie the cable bundle tightly to reduce its diameter
Answer: B
7. A technician is installing horizontal cabling in an office where the pathway
contains fluorescent lighting and electrical circuits. Why should appropriate
separation practices be maintained between communications cabling and
potential sources of interference?
A. Separation increases the cable's physical length
B. Separation changes the conductor gauge
C. Separation can reduce the effects of electromagnetic interference on
transmission performance
D. Separation eliminates the need for cable testing
Answer: C
8. A technician discovers that a horizontal cable has been sharply bent around
a metal edge because the pathway route is congested. What is the most
appropriate response?
A. Leave the cable in place because twisted-pair cable can tolerate any bend
B. Add additional tape around the bend
C. Increase the cable's pulling tension
D. Reroute the cable or correct the bend so installation remains within the
manufacturer's requirements
Answer: D
9. A technician is preparing a telecommunications outlet and needs to
determine the proper mounting location. Which consideration is most
important?
A. The outlet should be installed according to the approved design,
accessibility requirements, and work-area configuration
B. The outlet should always be placed at the highest possible point
pg. 3
, C. The outlet should be positioned wherever the cable is shortest
D. The outlet should be installed directly beside the nearest electrical
receptacle regardless of the design
Answer: A
10. During installation, a technician accidentally damages the jacket of a
Category-rated cable while removing it from a pathway. The conductors
appear intact. What should the technician do?
A. Hide the damaged section inside the telecommunications room
B. Evaluate the damage according to the manufacturer's requirements and
replace or repair the cable if its performance or mechanical integrity is
compromised
C. Apply ordinary adhesive and immediately certify the link
D. Increase the test limit so the cable will pass
Answer: B
11. A technician is terminating a high-performance balanced twisted-pair cable
and notices that the pair twists have been removed several inches farther
back than specified by the termination hardware. What is the primary
concern?
A. The cable will become too short
B. The jacket color may change
C. Excessive untwist can degrade the transmission characteristics of the link
D. The patch panel will automatically reverse polarity
Answer: C
12. A technician is labeling cables in a large telecommunications room
containing hundreds of connections. Which approach provides the greatest
long-term value?
A. Label only the cables that fail testing
B. Use informal technician nicknames for each cable
C. Label cables according to the approved standardized identification
