AVIXA Certified Technology Specialist CTS Exam Dumps: Updated Questions & Answers (October 2025)

The purchaser’s key role includes communication with vendors and internal staff, managing order timelines, pricing, and ensuring that the necessary components are available when needed, which is essential for project efficiency.

CTS Technology Specialist Reference

CTS materials highlight the role of procurement in maintaining project flow and ensuring timely delivery of AV components through effective vendor relations and internal coordination.

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.

A trunk line should be set up when connecting two switches with multiple VLANs. A trunk line allows the passage of traffic for multiple VLANs between switches. It tags the packets with the appropriate VLAN identifier, enabling the switches to properly route the traffic to the correct VLANs. This setup is essential for maintaining network segmentation and ensuring that all VLAN traffic is transmitted across the network as intended. Trunk lines are a standard networking practice for managing VLAN traffic between switches efficiently.

An incident meter measures the light coming directly from a source. This type of meter is used to measure the intensity of light that falls on a subject or area, as opposed to a reflected meter, which measures light that bounces off a surface. Incident light meters provide accurate readings of the lighting conditions, which is essential for calibrating AV systems. According to Axis documentation, using an incident meter is crucial for obtaining precise light measurements in AV setups.

Open ports are a common vulnerability in networked AV systems as they can be exploited by unauthorized users to gain access. If ports are not properly secured or managed, they provide entry points for potential security breaches. Ensuring ports are closed or properly protected is critical to securing AV systems.

CTS Technology Specialist Reference

The CTS training materials on network security in AV environments identify open ports as a significant security risk. Regular monitoring and management of open ports are recommended to prevent unauthorized access and protect networked AV systems.

The images shown represent keystone distortion, which occurs when a projector is not aligned perpendicularly to the screen. This misalignment results in a trapezoidal image rather than a rectangular one.

According to the AVIXA CTS Exam Guide, keystone distortion is covered under the Display Systems section, which states:

“Keystone distortion happens when the projector lens is not perpendicular to the screen plane, often due to improper vertical or horizontal positioning. The image appears wider at one end and narrower at the opposite, forming a shape like a keystone — hence the name.”

This distortion is not related to contrast (A), which refers to the difference between light and dark elements in an image, nor chromatic (B), which pertains to color distortion or aberration. While the shapes resemble trapezoids, trapezoid (D) is a description of the resulting shape, not the distortion type. The technical term for this specific distortion is keystone.

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.”

Zone D

In a mix-minus audio system, the microphones within each zone are typically routed to the speakers in other zones, excluding the zone they are in. This setup helps to avoid feedback, as it minimizes the likelihood of a microphone picking up sound from a nearby speaker broadcasting the same audio. For Zone C’s microphones to be the loudest, they should be directed to Zone D, which is adjacent to Zone C but not in the immediate vicinity of Zone C’s microphones.

Mix-minus configurations are common in conference rooms and other multi-zone environments, where sound needs to be clear and localized without causing feedback.

CTS Technology Specialist Reference

The CTS guidelines on sound system design discuss mix-minus as an approach to achieve speech clarity and prevent feedback in multi-zone audio systems by broadcasting microphones to other zones rather than the one they are in.

To mount a projector so that it is horizontally centered with the suspended screen, the technician should look at the reflected ceiling drawings in the plans. Reflected ceiling plans provide a view from above, showing the layout and alignment of ceiling elements, including projectors, screens, lighting, and other fixtures. This perspective is essential for ensuring that the projector is correctly aligned with the screen. Axis Technology Specialist documentation highlights the use of reflected ceiling plans for precise alignment of AV equipment.

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.
