• Question 11:

  The purpose of the system performance verification process is to:

  A. Conclude the installation phase and close out the project.
  B. Allow the AV contractor to send the final invoice for the project.
  C. Ensure the AV system meets substantial completion requirements.
  D. Provide a means for the AV contractor to objectively demonstrate the AV system meets performance criteria.
  D. Provide a means for the AV contractor to objectively demonstrate the AV system meets performance criteria.

  ---

  Explanation

  According to the AVIXA AV System Performance Verification Standard, the system performance verification process is intended to "objectively demonstrate that an AV system performs in accordance with the project documentation and to the client's expectations." This step ensures that all subsystems are tested and that performance meets the pre-established metrics. It's not merely administrative; it ensures compliance and satisfaction.

• Question 12:

  For ceiling speakers with a 90 degrees effective coverage angle, a ceiling height of 3 m (10 ft), and an ear height of 1.2 m (4 ft), the spacing for a 50% coverage or edge-to-center layout is:

  A. 1.8 m (6 ft)
  B. 3.0 m (10 ft)
  C. 3.6 m (12 ft)
  D. 6.0 m (20 ft)
  C. 3.6 m (12 ft)

  ---

  Explanation

  The formula for calculating speaker spacing for 50% coverage (edge-to-center) is: Spacing = 2 x (H - h) x tan(# / 2)

  Where:

  H = ceiling height = 3 m

  h = ear height = 1.2 m

  # = coverage angle = 90 degrees Plugging in the values: Spacing = 2 x (3 - 1.2) x tan(45 degrees)

  Spacing = 2 x 1.8 x 1

  Spacing = 3.6 m

  Therefore, the correct spacing is 3.6 m (12 ft).

• Question 13:

  What is the MAIN difference between OLED displays and LED displays?

  A. luminosity
  B. higher brightness
  C. self-emitting light source
  D. determined screen shape
  C. self-emitting light source

  ---

  Explanation

  The main difference between OLED (Organic Light Emitting Diode) displays and LED (Light Emitting Diode) displays is that OLED displays use self-emitting light sources. In OLED technology, each pixel emits its own light, allowing for better contrast ratios and deeper blacks, as pixels can be turned off completely. In contrast, LED displays use a backlight to illuminate the screen, which can result in less precise control over brightness and contrast.

• Question 14:

  A crucial part of the bid (tender) process is the request for clarification.

  At what point in the bid (tender) process would a potential bidder submit a request for clarification?

  A. After the award, but before the job begins
  B. After proposals are submitted, but before the award
  C. After the bid (tender) specifications are received, but before the proposals are due
  D. After the walkthrough, but before the bid (tender) specification package is sent out
  C. After the bid (tender) specifications are received, but before the proposals are due

  ---

  Explanation

  Requests for clarification are typically submitted after receiving the bid specifications but before the proposal submission deadline. This allows potential bidders to seek additional information or clarification on the project requirements to prepare accurate and comprehensive proposals.

• Question 15:

  Which preventive maintenance plan is most appropriate for a frequently used classroom AV system?

  A. Schedule periodic checks for filters, fans, connectors, cable strain, firmware status, lamp or light-source hours, and documented test results.
  B. Wait until a teacher reports a failure, then inspect only the failed device.
  C. Update firmware on every device immediately before each class starts.
  D. Remove maintenance logs after each visit to keep the room binder short.
  A. Schedule periodic checks for filters, fans, connectors, cable strain, firmware status, lamp or light-source hours, and documented test results.

  ---

  Explanation

  Preventive maintenance reduces failures by checking wear items, cooling, cabling, software or firmware state, light-source life, and system functions before users are affected. Waiting only for failures is reactive. Firmware work should be planned and tested, not performed casually before use, and maintenance logs are valuable service records.

• Question 16:

  Which of the following testing metrics would BEST be applied towards testing a distributed audio system for proper speaker wattages and cabling?

  A. Low-end system response 60 Hz and below
  B. High-end frequency response 10 kHz and above
  C. Audio uniformity in the range of intelligible speech 100 Hz - 2 kHz
  D. Audio uniformity across the entire spectrum of humanhearing60 Hz - 20 kHz
  C. Audio uniformity in the range of intelligible speech 100 Hz - 2 kHz

  ---

  Explanation

  When testing a distributed audio system, focusing on the audio uniformity in the range of intelligible speech (100 Hz - 2 kHz) is most important. This range is crucial for ensuring that speech is clear and understandable, which is often the primary function of distributed audio systems in environments like schools, offices, and public spaces. Ensuring uniform sound distribution within this frequency range helps achieve consistent audio quality and speech intelligibility across the covered area.

• Question 17:

  Several AV-over-IP endpoints show intermittent video dropouts.

  What should be checked before replacing endpoints?

  A. Switch port errors, link speed, bandwidth, multicast or IGMP configuration, VLAN assignment, and recent network changes.
  B. The wall plate engraving style and the color of the patch cables.
  C. Only whether the endpoint power LEDs are on.
  D. The room lighting level, because it directly changes packet delivery.
  A. Switch port errors, link speed, bandwidth, multicast or IGMP configuration, VLAN assignment, and recent network changes.

  ---

  Explanation

  Network video dropouts can be caused by infrastructure or configuration problems rather than failed endpoints. Port errors, negotiated speed, bandwidth limits, multicast control, VLANs, and network changes should be reviewed before hardware replacement. Power LEDs alone do not prove data-path health, and cosmetic details do not affect packet delivery.

• Question 18:

  What is the PRIMARY advantage of preventive maintenance?

  A. upfront costs
  B. system fail proof
  C. less equipment downtime
  D. better system performance
  C. less equipment downtime

  ---

  Explanation

  The primary advantage of preventive maintenance is reducing equipment downtime. By regularly maintaining and servicing equipment, potential issues can be identified and resolved before they lead to failures. This proactive approach ensures that systems remain operational and reduces the likelihood of unexpected breakdowns, which can be costly and disruptive. Preventive maintenance helps in maintaining system reliability and efficiency, ultimately contributing to better performance and longer equipment lifespan.

• Question 19:

  During a site survey of a facility to be upgraded or modernized, it is important to check wireless microphones that may be redeployed to ensure.

  A. battery types conform to environmental concerns.
  B. polar patterns will not clash with new fabric treatments.
  C. microphones are operating on acceptable radio frequencies.
  D. antenna design will not interfere with HDBaseT signal distribution system.
  C. microphones are operating on acceptable radio frequencies.

  ---

  Explanation

  When upgrading or modernizing a facility, it is essential to check that wireless microphones are operating on acceptable radio frequencies. This ensures compliance with local regulations and avoids interference with other wireless devices.

  The radio frequency spectrum can change over time, and certain frequencies may be reallocated or restricted, making it necessary to verify that existing equipment is still compliant and operational within the allowable frequency bands.

• Question 20:

  The best practice for tagging AV equipment for inventory management is to

  A. only tag Items over $99.00 in value.
  B. use a unique identifier for each item.
  C. include the value of each item on the tag.
  D. label all Items of the same model with a common identifier.
  B. use a unique identifier for each item.

  ---

  Explanation

  The best practice for tagging AV equipment for inventory management is to use a unique identifier for each item. This ensures that each piece of equipment can be tracked individually, reducing the risk of loss or confusion. Unique identifiers can include barcodes or RFID tags, which facilitate accurate and efficient tracking of inventory. Axis Technology Specialist documentation stresses the importance of unique identifiers in maintaining precise records and managing assets effectively.
