1. Certifying the reliability of the customer's drop system involves which of the following primary
actions?
A) Performing a speed test on all connected devices
B) Replacing any defective drop components
C) Upgrading all cable to fiber optic
D) Installing new customer premises equipment
Correct Answer: B) Replacing any defective drop components
Rationale: Certifying drop system reliability requires identifying and replacing defective components
throughout the drop system, including connectors, splitters, and cable sections that may be compromised
or performing below specifications.
2. What is one essential step in verifying that the digital set-top terminal is operating normally during
installation?
A) Checking the HDMI cable connection
B) Calling dispatch or the person designated with access to the billing system software to have the set-top
terminal authorized
C) Verifying the remote control batteries are fresh
D) Confirming the television is set to the correct input
Correct Answer: B) Calling dispatch or the person designated with access to the billing system software
to have the set-top terminal authorized
Rationale: Authorization from the billing system is critical for digital set-top terminal operation, as the
device must be activated and provisioned in the system to receive and decode the appropriate services.
3. When installing the Network Interface Unit (NIU), which tool would you use to verify proper
telephone functionality?
A) Spectrum analyzer
B) Cable modem tester
C) A dial-pulse telephone test set to check dial tone on inbound and outbound call capability
D) Multimeter for voltage testing only
,2
Correct Answer: C) A dial-pulse telephone test set to check dial tone on inbound and outbound call
capability
Rationale: A dial-pulse telephone test set enables verification of both inbound and outbound call
capabilities through the NIU, ensuring the telephony service is properly provisioned and functional before
leaving the premises.
4. In twisted pair cable network powering installations, what is the correct procedure for connecting
power cables?
A) Connect the power cables from the power distributing tap first
B) Always wire the twisted pair power cables first to the NIU power terminals and then to the power
terminal of the power distributing tap
C) Connect to the power distributing tap before the NIU
D) The order of connection does not matter
Correct Answer: B) Always wire the twisted pair power cables first to the NIU power terminals and then
to the power terminal of the power distributing tap
Rationale: Proper wiring sequence ensures safe and reliable power distribution, preventing potential
damage to equipment and maintaining proper polarity during installation.
5. Telephony inside wiring is routed from the NID or distribution device through which method?
A) Directly through the exterior wall without fittings
B) The appropriate compression fitting
C) Using only electrical tape and wire nuts
D) Through the nearest available conduit
Correct Answer: B) The appropriate compression fitting
Rationale: Compression fittings provide secure, weatherproof connections for telephony inside wiring,
maintaining signal integrity and preventing moisture intrusion at entry points.
6. When testing and verifying NIU operation, what is the correct procedure to confirm outbound call
capability?
A) Check for dial tone only
B) Call the provisioning center from the test phone or butt set to verify the ability to place an outbound
call
C) Verify the customer's telephone is connected
D) Test only inbound calling
Correct Answer: B) Call the provisioning center from the test phone or butt set to verify the ability to
place an outbound call
Rationale: Placing an actual outbound call confirms that the NIU can successfully complete a call
through the network, verifying both functionality and proper provisioning.

7. Items to check in order to certify the reliability of the customer drop system include which of the
following?
A) Only visual inspection of cables
B) Installing high pass filters and directional couplers, if needed, and monitoring, detecting, and
eliminating signal leakage
C) Replacing all connectors
D) Testing only the cable modem
Correct Answer: B) Installing high pass filters and directional couplers, if needed, and monitoring,
detecting, and eliminating signal leakage
Rationale: Comprehensive drop system reliability requires both proper filtering and signal leakage
detection, ensuring signal integrity and compliance with FCC regulations.
8. The customer access area of an NIU provides access to which components?
A) Only the power supply
B) The broadband cable output port, RJ-11 testjacks, and telephone tip and ring wiring connectors
C) Only the telephone connectors
D) The cable modem and router
Correct Answer: B) The broadband cable output port, RJ-11 testjacks, and telephone tip and ring wiring
connectors
Rationale: The NIU customer access area provides multiple connection points for both broadband and
telephony services, enabling testing and customer equipment connections.
9. Which of the following are tests/measurements that can be made on a VOM (Volt-Ohm-Meter)?
A) Frequency and wavelength
B) Voltage DC and AC, and opens and shorts
C) Signal-to-noise ratio only
D) Bit error rate and throughput
Correct Answer: B) Voltage DC and AC, and opens and shorts
Rationale: A VOM is essential for measuring DC and AC voltage and testing continuity, opens, and shorts
in cables and circuits during installation and troubleshooting.
10. The federal government mandates the amount of __________ that is acceptable for cable networks.
A) Bandwidth
B) Power consumption
C) Egress
D) Noise floor
, 4
Correct Answer: C) Egress
Rationale: The FCC strictly regulates signal egress (leakage) from cable networks to prevent interference
with aeronautical and other communications frequencies, with specific cumulative leakage index
requirements.
11. What is the main purpose of the MAC address on an EMTA (Embedded Multimedia Terminal
Adapter)?
A) To identify the manufacturer of the device
B) Provides that authorization to ensure only the customer's account in the billing system is assigned to
that address
C) To enable Wi-Fi connectivity
D) To determine the device's location
Correct Answer: B) Provides that authorization to ensure only the customer's account in the billing
system is assigned to that address
Rationale: The MAC address uniquely identifies the EMTA in the cable network, and the billing system
associates services with this address to prevent unauthorized service usage.
12. The NID (Network Interface Device) serves as what in the telecommunications network?
A) The main power supply
B) The demarcation point between CPE network and the local telephone company's network
C) The cable modem termination system
D) The fiber optic transceiver
Correct Answer: B) The demarcation point between CPE network and the local telephone company's
network
Rationale: The NID marks the boundary of responsibility between the service provider and the customer
for inside wiring and equipment, providing a clear demarcation point.
13. The process of keeping your telephone number when switching from one provider to another is called
what?
A) Forwarding
B) Transferring
C) Porting
D) Routing
Correct Answer: C) Porting
Rationale: Number portability allows customers to retain their telephone number when changing service
providers, mandated by FCC regulations to promote competition in telecommunications.
