• Question 21:

  According to the Gantt chart pictured, the Project Manager should wait to start Activity C until which predecessor has been reached?

  

  A. Week 3
  B. Week 4
  C. Activity B
  D. Milestone X
  D. Milestone X

  ---

  Explanation

  In the provided Gantt chart, Activity C is scheduled to start after the completion of Milestone

  X. This is evident as the milestone symbol (diamond) for Milestone X appears right before the beginning of Activity C, indicating that Activity C is dependent on the completion of Milestone

  X.

• Question 22:

  Constant voltage distributed audio systems utilize a_____wiring scheme.

  A. star
  B. loop
  C. series
  D. parallel
  D. parallel

  ---

  Explanation

  Constant voltage distributed audio systems use a parallel wiring scheme, allowing multiple speakers to be connected to a single amplifier without needing to match impedances precisely. This setup is common in large venues where many speakers are distributed over a wide area.

  CTS Technology Specialist Reference

  CTS materials explain that parallel wiring is standard in constant voltage systems, as it simplifies installation and allows for flexible speaker placement across large areas.

• Question 23:

  By code, projection screens should be positioned in a manner that avoids blocking.

  A. lines of sight and lectern access.
  B. paintings, cabinets, and sliding doors.
  C. alarm indicators, clocks, and light switches.
  D. windows, aquariums, and other glass surfaces.
  C. alarm indicators, clocks, and light switches.

  ---

  Explanation

  Projection screens should be positioned to avoid obstructing alarm indicators, clocks, and light switches, as these are critical elements within a room that need to remain accessible and visible. Ensuring they are not blocked helps maintain safety and usability within the space.

  CTS Technology Specialist Reference

  As per CTS guidelines, projection screen placement should consider accessibility and visibility of room elements critical to operation and safety, like alarms and controls.

• Question 24:

  HOTSPOT

  Which microphone pattern is MOST susceptible to feedback? Select the correct pattern by clicking on it.

  

  

  ---

  The second pattern from the left (the figure-eight pattern). The figure-eight (or bidirectional) microphone pattern is the most susceptible to feedback among the choices shown. This pattern picks up sound equally from both the front and rear of the microphone while rejecting sound from the sides. Due to its large rear lobe, it is prone to capturing sounds from reflective surfaces or rear-facing speakers, which can lead to feedback in a live sound environment. Here's a breakdown of the patterns: First pattern (Omnidirectional): Captures sound from all directions. While it can be prone to feedback, it doesn't have a rear lobe like the figure-eight pattern. Second pattern (Figure-eight/Bidirectional): Susceptible to feedback because it picks up equally from both front and back, which can include unwanted sound reflections. Third and Fourth patterns (Cardioid and Supercardioid): These are more directional with better rear rejection, thus less susceptible to feedback.

  Fifth pattern (Shotgun): Highly directional with minimal pickup from the rear and sides, making it the least susceptible to feedback.

  CTS Technology Specialist Reference

  CTS materials on microphone types and placement emphasize that bidirectional (figure-eight) microphones should be positioned carefully in live sound setups to avoid unwanted rear lobe pickup, which can lead to feedback when speakers are positioned behind or to the sides of the microphone.

• Question 25:

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

  A. Luminosity
  B. Higher brightness
  C. Self-emitting light source
  D. Determined screen shape
  C. Self-emitting light source

  ---

  Explanation

  OLED (Organic Light Emitting Diode) displays differ from LCDs primarily because each pixel emits its own light, eliminating the need for a backlight. This allows for true blacks, better contrast, and thinner display construction. "Unlike LCD panels, OLED displays are self-emissive, which means each pixel produces its own light. This allows OLED to achieve deeper blacks and better contrast." -AVIXA CTS Exam Guide, Display Technologies Chapter

• Question 26:

  A client wants to install new ceiling microphones to an existing system.

  Which trade does the technician need to coordinate with for the microphone placement?

  A. HVAC
  B. Painting
  C. Plumbing
  D. Interior design
  A. HVAC

  ---

  Explanation

  Ceiling microphones are sensitive to air handling noise. Coordination with HVAC is crucial to avoid placing microphones near noisy vents or ducts, which can cause unwanted ambient noise and reduce intelligibility. "Microphones should be kept clear of HVAC vents and diffusers. Coordination with mechanical trades prevents noise contamination."

• Question 27:

  Which of these cables should be used for Ethernet transmission over 1 mile (1.6 km)?

  

  A. A
  B. B
  C. C
  D. D
  C. C

  ---

  Explanation

  The only cable in the image capable of Ethernet transmission over 1 mile (1.6 km) is, which is C fiber optic cable.

  # Why? According to the AVIXA CTS Exam Guide and industry standards such as IEEE 802.3: Twisted pair cables (like A and B) are limited to 100 meters (328 feet) for Ethernet. Coaxial cable (D) is typically not used for long-distance Ethernet and has high attenuation over distance. Fiber optic cable (C) can support data transmission over kilometers depending on the type (single-mode or multi-mode). For 1 mile (1.6 km), single-mode fiber is ideal. From the CTS Exam Guide, 5th Edition - Chapter 3: Networking, it explains: "For high-speed and long-distance data communication, fiber optic cabling is essential. Single-mode fiber can transmit Ethernet over distances exceeding 10 km, making it the only practical choice for transmissions over 1 mile."

  Additionally: Fiber is immune to electromagnetic interference.

  Provides higher bandwidth and lower attenuation compared to copper-based cables.

• Question 28:

  When an audio device can no longer accurately reproduce the audio signal, It is called

  A. feedback.
  B. dithering.
  C. distortion.
  D. saturation.
  C. distortion.

  ---

  Explanation

  Distortion occurs when an audio device can no longer accurately reproduce the input audio signal. This happens when the signal exceeds the device's capacity to process it linearly, resulting in a corrupted output that differs from the original signal. Distortion can be caused by overloading the device's input or output stages, improper gain settings, or defects in the audio components. It degrades the quality of the audio signal and can manifest as unwanted noise or alterations in the sound.

• Question 29:

  To help end users remember key points of the training, the training documentation should include.

  A. equipment datasheets.
  B. a customized quick start guide.
  C. user manuals for each piece of equipment.
  D. instructions for maintaining system input devices.
  B. a customized quick start guide.

  ---

  Explanation

  A customized quick start guide is particularly useful for helping end users remember key points of the training. These guides provide concise, easy-to-follow instructions tailored to the specific system and user needs, highlighting the most important operational steps and features. This helps users quickly familiarize themselves with the system and perform essential tasks without having to refer to extensive manuals. Including visual aids, such as diagrams and screenshots, further enhances the effectiveness of the quick start guide.

• Question 30:

  Which of the following project management activities coordinates project requirements and resources?

  A. project budget
  B. logic model timeline
  C. logic network diagram
  D. project kick-off meeting
  C. logic network diagram

  ---

  Explanation

  A project kick-off meeting is the project management activity that coordinates project requirements and resources. This meeting involves all stakeholders and team members to ensure everyone understands the project scope, objectives, timelines, and resource allocations. It sets the stage for the project execution and aligns the team on the plan ahead. According to Axis Technology Specialist documentation, project kick-off meetings are crucial for aligning expectations and ensuring all necessary resources are allocated effectively from the start.
