• Question 131:

  While troubleshooting a DSP, the AV technician notices that the DHCP server has failed due to the control system not being able to control the volume of the DSP. In order to restore the same IP, the control programmer requires a unique identifier assigned to the network interface card of the DSP.

  What is the name of that address?

  A. media access control
  B. internet protocol address
  C. network address translation
  D. digital multiplex exchange address
  A. media access control

  ---

  Explanation

  Comprehensive Detailed Explanation with all

  Technology Specialist References: The unique identifier assigned to a network interface card (NIC) is known as the Media Access Control (MAC) address.

  A MAC address is a hardware address that is permanently embedded into the network interface of a device, such as a DSP, and is used to uniquely identify it on a local network. When DHCP fails, the control programmer may need the MAC address to reassign the same IP address, as DHCP reservations are often based on MAC addresses.

  This ensures that devices receive a consistent IP address each time they connect, which is crucial for network devices in an AV system that rely on static IPs for control purposes. Option B, "internet protocol address," refers to the IP address, which is assigned to a device but not unique to the hardware, as it can change over time.

  Option C, "network address translation," is a method for modifying IP address information as it passes through a router.

  Option D, "digital multiplex exchange address," is not relevant in this context and does not pertain to IP networking or AV control systems.

  ---

  Explanation

  The viewing category that describes the usage of a display as a reference for CAD drawings is ADM (Analytical Decision Making). This category involves the detailed examination and interpretation of complex information, such as technical drawings or data. Displays used for ADM must have high resolution and clarity to ensure accurate analysis. Axis Technology Specialist documentation categorizes displays for analytical decision-making tasks as requiring superior visual performance to support detailed and precise work.

• Question 134:

  What does a compressor control in an audio system?

  A. phase
  B. directivity
  C. frequency
  D. dynamic range
  D. dynamic range

  ---

  Explanation

  In an audio system, a compressor controls the dynamic range by reducing the difference between the loudest and quietest parts of the audio signal. Compressors are used to maintain a consistent volume level, which is useful for both live and recorded audio environments.

  CTS Technology Specialist Reference

  CTS curriculum covers audio processing tools like compressors, which are essential for managing dynamic range and ensuring consistent audio output.

• Question 135:

  A client approves the business need for a divisible training room.

  What should a functional AV project scope primarily define?

  A. Required functions, operating modes, constraints, deliverables, responsibilities, and acceptance criteria.
  B. Only the exact model numbers selected by the dealer at the time of quoting.
  C. Only the installation crew list and the expected daily start time.
  D. Only the decorative finish of the wall plates and rack panels.
  A. Required functions, operating modes, constraints, deliverables, responsibilities, and acceptance criteria.

  ---

  Explanation

  A functional scope states what the AV solution must do and how success will be judged. It should describe room combine modes, source routing, conferencing behavior, control expectations, constraints, deliverables, responsibilities, and acceptance criteria. Model numbers, staffing details, and finish choices may appear elsewhere, but they do not define the complete functional requirement.

• Question 136:

  When training a new user to operate the solution that has been provided, how should the training be started?

  A. With a good joke.
  B. With the display up and running.
  C. With the system up and running.
  D. With the system shut down and at a state of rest.
  D. With the system shut down and at a state of rest.

  ---

  Explanation

  Training users should begin with the system in a shutdown state to ensure they understand the basic steps of powering on and initializing the equipment. Starting from a state of rest allows the user to become familiar with the startup sequence, which is essential for operating the system independently and troubleshooting initial issues.

  CTS Technology Specialist Reference

  CTS training emphasizes starting with equipment off during training sessions to ensure users learn correct startup procedures, ensuring the longevity and proper functioning of the AV system.

• Question 137:

  What is the main purpose of commissioning an AV system before client handoff?

  A. Verify the installed system against the design and acceptance criteria, document results, and resolve punch-list items.
  B. Confirm only that every device powers on.
  C. Replace formal testing with a quick demonstration by the salesperson.
  D. Delay system testing until the first live event.
  A. Verify the installed system against the design and acceptance criteria, document results, and resolve punch-list items.

  ---

  Explanation

  Commissioning verifies that the installed AV solution meets the documented design and acceptance criteria. It includes functional testing, measurement or configuration checks where needed, documentation of results, and resolution of remaining issues. Power-on checks or informal demos alone do not prove that the system is ready for handoff.

• Question 138:

  A client requests for a project to be completed earlier than initially scheduled.

  What should the AV contractor do FIRST to address this change?

  A. deny the request and work to the original agreed schedule
  B. allocate more resources to meet the earlier completion date
  C. provide a request for change (RFC) to the client to approve the change to the schedule
  D. provide a change order (CO) to the client outlining changes to the project and any additional costs
  C. provide a request for change (RFC) to the client to approve the change to the schedule

  ---

  Explanation

  When a client requests an earlier project completion date, the AV contractor should first issue a Request for Change (RFC). This formal request documents the proposed schedule change and requires client approval. It allows for assessment of resource requirements, timeline adjustments, and any potential cost implications.

  CTS Technology Specialist Reference

  The CTS guidelines stress documenting changes through formal requests like RFCs to ensure client approval and clarity on any impact to the project.

• Question 139:

  HOTSPOT

  Which setting on the digital multimeter should be used to determine if a DC power supply has failed?

  Select the correct measurement category by clicking anywhere within the measurement range.

  

  

  ---

  The correct setting is the section marked with "V#" (DC Voltage), specifically within the range that matches your expected DC power supply output, e.g., 20V under the "V#" section. According to the AVIXA CTS Exam Guide, Chapter 6: Troubleshooting, checking if a DC power supply has failed requires measuring the DC output voltage. This involves setting your multimeter to the DC voltage (V#) range that covers the expected output.

  From the guide:

  "When testing a DC power source, use the DC voltage range on your digital multimeter. Begin with a higher range (e.g., 200V) to avoid damaging the meter, then narrow down for precision if needed." Avoid using resistance (#), AC voltage (V~), or current (A) ranges when checking voltage output.

• Question 140:

  Signal flow on a schematic is conventionally shown in which direction?

  A. Left to right
  B. Right to left
  C. Top to bottom
  D. Bottom to top
  A. Left to right

  ---

  Explanation

  In AV system schematics, signal flow is traditionally depicted from left to right. Inputs (sources) are placed on the left, and outputs (displays, speakers) are on the right. This makes signal tracing intuitive and consistent for documentation and troubleshooting.

  "Standard AV system drawings depict signal flow from left to right, starting at source and ending at output, to provide logical signal tracing." -CTS Exam Guide, Documentation and Schematics Chapter
