  1. What does the term 'headend' refer to in a distributed video system?

    Answer: The central equipment location where sources are aggregated and distributed

    The headend is the central hub where all video sources are collected, processed, and then distributed to remote displays throughout a facility.

  2. During a multi-room AV installation, the technician discovers that power outlets in several locations are on circuits shared with HVAC equipment. What is the recommended course of action?

    Answer: Request dedicated circuits for AV equipment from a licensed electrician

    HVAC equipment creates electrical noise and voltage fluctuations that can damage AV equipment or cause interference; dedicated circuits from a licensed electrician eliminate this risk.

  3. A technician is installing speakers in a plenum ceiling space. What cable type is required by the NEC for this installation?

    Answer: CMP-rated (plenum-rated) cable

    The NEC requires CMP (Communications Plenum) rated cable in plenum spaces because it produces less smoke and toxic fumes when exposed to fire, protecting HVAC air pathways.

  4. What is the function of a balun in an AV installation?

    Answer: To convert an unbalanced signal to balanced (or vice versa) or to transmit AV signals over twisted-pair cable

    A balun converts between balanced and unbalanced signal formats and is commonly used to extend AV signals over Cat cable, reducing noise and extending transmission distances.

  5. When configuring a matrix switcher for a large installation, the technician should verify which parameter to prevent signal degradation when routing 4K content?

    Answer: The switcher's HDCP compliance and 4K/HDMI 2.0 bandwidth support

    4K signals require HDMI 2.0 bandwidth (18 Gbps) and HDCP 2.2 compliance; a switcher lacking these specifications will fail to pass 4K HDR content correctly.

  6. A client reports that a motorized projection screen intermittently stops at inconsistent heights during descent. What is the most likely cause?

    Answer: A faulty or misadjusted limit switch on the screen motor

    Motorized screens use limit switches to define travel endpoints; a faulty or improperly adjusted limit switch causes the screen to stop at inconsistent positions.

  7. Which test should a CTS technician perform after completing all cable terminations in a structured wiring installation to verify proper connectivity and signal integrity?

    Answer: A cable certification test using a field tester that measures insertion loss, return loss, and NEXT

    Cable certification testing with a field tester validates all transmission parameters (insertion loss, NEXT, return loss) against TIA/ISO standards, confirming the installation will support the intended application.
