Free AVIXA-CTS sample questions

Correct answer: Use a certified cable tester to verify all pairs in the category cable are correctly terminated and meet performance standards.

The most logical next step is to verify the integrity of the physical transport layer. Since HDBaseT relies on category cable, using a certified tester will confirm continuity, termination (T568A/B), and performance for the given length. Replacing components like the camera or extenders is a more drastic and expensive step to take before confirming the cable infrastructure, which is a common point of failure.

Correct answer: 2 ohms

The formula for calculating total impedance (Z_total) for speakers in parallel is 1/Z_total = 1/Z1 + 1/Z2 + ... + 1/Zn. For identical speakers, this simplifies to Z_total = Z_speaker / number_of_speakers. In this case, Z_total = 8 ohms / 4 speakers = 2 ohms. This low impedance load must be compatible with the amplifier's specifications to prevent damage.

Correct answer: False

A preventative maintenance agreement covers scheduled service activities like cleaning filters, checking connections, and updating firmware. A manufacturer's warranty covers failures due to defects. While the technician performing maintenance might diagnose a warranty issue, the cost of the replacement part itself is covered by the warranty, not the maintenance agreement. The labor to replace the item may be covered by either, depending on the contract terms.

Correct answer: Creating and providing a laminated, one-page Quick Start Guide (QSG) focused on the 3-5 most common tasks, and leaving it in the room.

The most effective training tool for day-to-day users is a simple, task-oriented Quick Start Guide. It empowers users to handle common scenarios (e.g., 'Start a presentation', 'Join a video call') without needing to recall a long training session or read a technical manual. This approach drastically reduces support calls and increases user confidence and system adoption.

Correct answer: The high level of uncontrolled ambient light from the windows.

Uncontrolled ambient light from large windows is a major issue for video systems. It can wash out projector or display images, making them difficult to see. For video conferencing, it can create harsh backlighting on participants, making them appear as silhouettes to far-end viewers. This requires a discussion about lighting control, such as motorized shades, which can be a significant cost consideration.

Correct answer: 1.2 meters (4.0 feet)

According to AVIXA standards and general AV design best practices, the bottom of the image should be a minimum of 1.2 meters (4 feet) above the finished floor. This helps ensure that viewers in the back of the room can see over the heads of those seated in front of them, maintaining clear sightlines to the entire screen.

Correct answer: 19410 lumens

1. Find required screen brightness (foot-lamberts): Ambient Light (fc) * Contrast Ratio = 25 fc * 20 = 500 fL. 2. Convert required brightness (fL) to lumens: (Required fL * Screen Area (sq ft)) / Screen Gain. 3. Calculation: (500 fL * 42.7 sq ft) / 1.1 gain = 21350 / 1.1 = 19409 lumens. The minimum required output is approximately 19410 ANSI lumens.

Correct answers: System schematics and signal flow diagrams; Rack elevation drawings; Architectural drawings showing device locations and infrastructure

Correct answer: To specify the physical placement of equipment in the rack for thermal management and serviceability.

A rack elevation diagram is a visual representation of the front and rear of an equipment rack. Its primary purpose is to show the exact physical arrangement of all components. This is crucial for planning thermal management (e.g., placing high-heat devices like amplifiers with proper ventilation) and ensuring service access to connections and controls.

Correct answer: Checking if the source device is powered on and outputting a signal.

The flowchart correctly checks the display power and input selection but completely omits verifying the status of the source device. Before replacing a cable, a fundamental troubleshooting step is to confirm that the source device (e.g., laptop, media player) is powered on and actively outputting a video signal.
