AVIXA AVIXA-CTS Online Questions & Answers

• Question 201:

  A 2x2 video wall was sold with each display being Full HD resolution. Now the client wants to show live content at the best possible quality over the complete wall.

  Which resolution must the camera provide?

  A. 1920 x 1080
  B. 3840 x 2160
  C. 4096 x 2160
  D. 7680 x 4320
  D. 7680 x 4320

  ---

  Explanation

  Each display in a 2x2 video wall setup at Full HD resolution (1920 x 1080) requires a total resolution of 3840 x 2160 for two displays horizontally and 2160 x 2 vertically, which equals 7680 x 4320. This resolution ensures each display shows content at the highest quality without scaling down.

• Question 202:

  A vendor proposes a lower-cost display as an alternate to the specified model.

  What is the best CTS-level response?

  A. Compare the alternate against required performance, inputs, mounting, control, power, availability, warranty, and acceptance criteria.
  B. Accept the alternate automatically because it reduces the purchase price.
  C. Reject the alternate automatically because it is not the originally specified model.
  D. Delay the comparison until after the display has been installed.
  A. Compare the alternate against required performance, inputs, mounting, control, power, availability, warranty, and acceptance criteria.

  ---

  Explanation

  An alternate can be acceptable only if it satisfies the functional and technical requirements of the project. Performance, connectivity, mounting, control compatibility, power, lead time, support, warranty, and acceptance criteria should be reviewed before approval. Price alone is not enough, and rejecting every alternate without evaluation can also harm the project.

• Question 203:

  What are the dimensions of UHD resolution?

  A. 2560 x 1440 pixels
  B. 3840 x 2160 pixels
  C. 2048 x 1080 pixels
  D. 4096 x 2160 pixels
  B. 3840 x 2160 pixels

  ---

  Explanation

  Ultra High Definition (UHD) resolution is defined as 3840 x 2160 pixels. This resolution is commonly referred to as 4K UHD and provides four times the resolution of Full HD (1920 x 1080 pixels). UHD offers greater detail, clarity, and overall image quality, making it suitable for large displays and high-definition content.

• Question 204:

  What results from connecting a computer to the network using DHCP?

  A. Access to router
  B. A static IP address
  C. A dynamic IP address
  D. Password to get into the network
  C. A dynamic IP address

  ---

  Explanation

  DHCP (Dynamic Host Configuration Protocol) automatically assigns an IP address from a pool to a connected device. This allows devices to join a network without manual configuration. "DHCP allows for automatic network configuration, assigning dynamic IP addresses, simplifying connectivity for mobile or temporary devices."

• Question 205:

  What is the aspect ratio in these images?

  

  A. 1.33:1
  B. 4:3
  C. 5:4
  D. 16:9
  D. 16:9

  ---

  Explanation

  The aspect ratio is the ratio of the width to the height of an image. In the given images, the larger display has a width of 47.6 inches and a height of 26.89 inches. The aspect ratio is calculated as: Aspect Ratio=WidthHeight=47.626.89#1.77:1\text{Aspect Ratio} = \frac{\text{Width}}{\text{Height}} = \frac{47.6}{26.89} \approx 1.77:1Aspect Ratio=HeightWidth=26.8947.6#1.77:1 This approximates to 16:9, which is a common widescreen aspect ratio used in modern displays and television screens.

• Question 206:

  Assuming 120V as the power source, how many amperes does a 240W device draw?

  A. 1
  B. 2
  C. 5
  D. 7
  B. 2

  ---

  Explanation

  Using Ohm's Law:

  "To calculate current draw, divide wattage by voltage. This helps ensure proper circuit planning and electrical safety."

• Question 207:

  A revised bill of materials adds several power amplifiers and large displays to an equipment rack.

  What should be coordinated with the facility team before installation?

  A. Electrical load, branch circuit capacity, heat output, rack ventilation, and HVAC impact.
  B. The color order of network patch cords inside the rack.
  C. The brand name printed on the front panel of each device.
  D. The order in which the equipment appears on the sales quote.
  A. Electrical load, branch circuit capacity, heat output, rack ventilation, and HVAC impact.

  ---

  Explanation

  Power and thermal requirements can affect safety, reliability, and building infrastructure. The facility team should confirm circuit capacity, load distribution, heat output, ventilation, and HVAC capability before equipment is installed. Cable colors, brand labels, and quote order do not confirm that the rack can operate safely.

• Question 208:

  HOTSPOT

  The video conferencing suite shown has a large conference table centered in the room.

  Dimming which of the COLORED zones would tend to decrease facial shadows? Select the answer by clicking on any light fixture within a zone.

  

  

  ---

  Yellow-colored zones (any light fixture within the yellow zones directly above the seating area). In video conferencing, balanced and well-placed lighting is crucial for achieving good facial visibility and reducing harsh shadows. Overhead lights can cast shadows on participants' faces, particularly under the eyes and nose, which can detract from a professional appearance on camera. By dimming lights directly above (in this case, the yellow zones), you reduce the intensity of the light falling straight down onto faces, softening shadows and creating more even lighting.

  Dimming lights in the green or blue zones would be less effective, as they are positioned at the perimeter of the room and provide indirect lighting that does not directly influence facial shadows over the conference table.

• Question 209:

  Which is the MOST important factor during the development of an AV project scope?

  A. entire budget
  B. clients responsibility
  C. analyze the strategic plan
  D. stakeholders requirements
  D. stakeholders requirements

  ---

  Explanation

  The most important factor during the development of an AV project scope is understanding stakeholders' requirements. This ensures the project aligns with the needs and expectations of those who will be using or impacted by the system, making it central to project success.

  CTS Technology Specialist Reference

  CTS training underscores the importance of gathering detailed stakeholder requirements to define a project scope that meets the client's objectives and use cases.

• Question 210:

  System performance verification occurs when the system is

  A. in need of repair.
  B. completely installed.
  C. removed from service.
  D. approved by the customer.
  B. completely installed.

  ---

  Explanation

  System performance verification occurs when the system is completely installed. This process involves testing all components and ensuring that the system meets the design specifications and functions as expected before it is handed over to the client. It is a critical step for quality assurance and confirming that the installation meets both the technical and functional requirements.

  CTS Technology Specialist Reference

  According to CTS standards, performance verification is conducted post-installation to validate that the system is operating correctly, helping to address any issues before final client approval.
