CTS AVIXA Certified Technology Specialist Free Practice Exam Questions (2025 Updated)

Before swapping hardware or updating firmware, the first step in any troubleshooting scenario is to check physical connections. Loose or improperly seated cables are one of the most common causes of intermittent signal loss.

“Physical inspection is the first troubleshooting step, especially for signal loss. Cable reseating often resolves intermittent issues.”

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.

The issue described is likely due to HDCP (High-bandwidth Digital Content Protection) incompatibility. Since PC B does not work through the switcher but works directly, it indicates an HDCP handshake issue between the switcher and PC B. Adding an HDCP-compliant device, such as an HDCP-compliant switcher or repeater, can resolve this issue by ensuring that content protection protocols are properly managed.

CTS materials on digital video highlight the importance of HDCP management when dealing with protected content in HDMI connections, especially in videoconferencing systems.

Legibility of text on a display is directly related to the height of the characters. As the height increases, the text becomes easier to read from a distance because the characters are larger and more distinct. This is a fundamental principle in design and ergonomics, ensuring that text is easily readable for users in various viewing conditions. This is particularly important in contexts such as digital signage, user interfaces, and public information displays.

WUXGA stands for Wide Ultra Extended Graphics Array and has a resolution of 1920 x 1200 pixels. To determine the aspect ratio, we divide the width by the height:

=1.6:1\text{Aspect Ratio} = \frac{1920}{1200} = 1.6:1Aspect Ratio=12001920​=1.6:1

Therefore, the aspect ratio for WUXGA is 1.6:1. This aspect ratio is common for widescreen monitors and provides a wider display format compared to traditional 4:3 screens, enhancing the viewing experience for multimedia content.

The systems integration phase is when devices are installed and configured together. Verifying loudspeaker transformer taps during this phase ensures that each speaker receives the correct power level, which is critical for achieving uniform audio coverage and system performance.

“Loudspeaker transformer taps should be verified during the systems integration phase to ensure proper audio balance and coverage before final verification.”

For optimal viewing comfort, the top of a display should not be positioned more than 30 degrees above the viewer’s line of sight. This guideline ensures that viewers do not have to strain their necks to see the entire screen. While Options A and B might seem reasonable, 30 degrees is considered the upper limit for comfortable viewing, with viewers ideally positioned to see the full display without needing to look up excessively.

When installing underwater lighting in a swimming pool to match a client’s colors, the technician needs to consider the IP rating of the fixtures. The IP rating indicates the level of protection the fixtures have against water and dust. For underwater lighting, it is crucial to use fixtures with a high IP rating (typically IP68) to ensure they are fully waterproof and safe to operate underwater. Axis Technology Specialist documentation emphasizes the importance of selecting appropriately rated equipment for specific environmental conditions to ensure safety and functionality.

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.

Installers are directly involved with on-site activities and provide essential updates on daily progress, issues, and requirements. Regular updates from installers enable project managers to monitor timelines, resource allocation, and budget considerations more effectively.

CTS Technology Specialist Reference

CTS guidelines highlight the importance of regular communication with installers for tracking project progress, as they are most familiar with day-to-day developments and challenges.

The control system for the AV solution, assuming both the screen and projector are Ethernet controllable devices, needs to be connected to the network. This allows for centralized control, remote access, and management of the AV devices, ensuring seamless integration and operation. Axis documentation emphasizes the importance of network connectivity for managing Ethernet-enabled AV equipment effectively.

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.

The f-number (aperture) of a lens determines how much light passes through. An f/2.8 lens allows less light than an f/1.4 lens, resulting in a dimmer image. Specifically, each full f-stop reduces the light by a factor of four. So switching from f/1.4 to f/2.8 cuts the light significantly.

“The larger the f-number, the smaller the lens opening and the less light is transmitted, which reduces image brightness.”

A Request for Information (RFI) is a document used to clarify project design issues. RFIs are typically issued when there is a need for additional information or clarification on specific aspects of the project design. This helps ensure that all parties have a clear understanding of the requirements and can proceed with accurate and consistent implementation. RFIs are commonly used in construction and AV projects to address uncertainties or discrepancies in the design documents.

The term "luminaire" refers to a complete lighting instrument composed of a lamp and housing. This includes all components necessary for the fixture to function, such as the lamp (bulb), housing, reflector, and any other elements that contribute to its operation. Axis Technology Specialist documentation uses the term "luminaire" to describe complete lighting systems in various technical specifications and installation guides.

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.

=========================

This logistical detail should be planned during the site survey, which is when all site constraints (e.g., power, loading dock access, storage, waste handling) are assessed. Waiting until install day is too late.

“Site surveys must assess disposal options, material storage, and access constraints to avoid delays during installation.”

Preventive maintenance visits (PM/PMV) are primarily designed to ensure that equipment is functioning correctly and to prevent potential failures. This involves cleaning, servicing, and assessing the equipment regularly to maintain optimal performance and longevity. This is in line with industry standards for preventive maintenance, ensuring reliability and reducing downtime.

The cloud symbol (Option C) is commonly used to represent a network, particularly in diagrams to signify a network or cloud-based resources. This symbol has become a universal representation of network connections and internet-based services.

CTS Technology Specialist Reference

The CTS materials include standard AV and IT symbols, where the cloud symbol is used to denote networks and internet connections, aiding in clear communication within technical diagrams.
