AVIXA AVIXA-CTS Online Questions & Answers

• Question 111:

  Two computers are connected to a videoconferencing system through a switcher using HDMI cables. Computer content from PC A is being properly transmitted. However, when PC B is selected by the switcher, it does not work through the videoconferencing system. They both work when connected directly to the videoconferencing system or the monitor. The solution is to add a device that enables____management.

  

  A. DDC
  B. DHCP
  C. HDCP
  D. TMDS
  C. HDCP

  ---

  Explanation

  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 Technology Specialist Reference

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

• Question 112:

  When using an IR-based assistive listening system, where MUST the transmitter be located?

  A. Under the presenter's desk
  B. At the top of the AV equipment rack
  C. With line-of-sight to the audience area
  D. Within 25 feet (7.6 meters) of the wheelchair seating area
  C. With line-of-sight to the audience area

  ---

  Explanation

  Infrared (IR) assistive listening systems rely on line-of-sight transmission. The IR transmitter emits signals that must directly reach the receivers without obstruction. Therefore, it's imperative that the transmitter is positioned with a clear line-of-sight to the audience area to ensure effective signal transmission.

• Question 113:

  A client has a laser projector that fails and appears dead after six months' use. The documentation shows that the projector is covered by a return-to-base or back-to-bench warranty. The client can expect to:

  A. Receive remote-access repair service
  B. Receive on-site visit from service engineer
  C. Remove projector and ship back to manufacturer
  D. Remove projector and replace with advanced-shipped unit
  C. Remove projector and ship back to manufacturer

  ---

  Explanation

  A return-to-base (or back-to-bench) warranty requires the customer to send the device to the manufacturer or service center. Unlike advanced replacement or on-site service warranties, the burden is on the client to remove and ship the equipment.

  "Return-to-base warranties require the customer to ship the device to the service location, often at their own cost."

• Question 114:

  Your client has requested a 50inch monitor be mounted on the south wail of this boardroom.

  Which two recessed lights will need to be separated into the r own zone in order to turn them off when the monitor is on?

  

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

  ---

  Explanation

  For mounting a 50-inch monitor on the south wall of the boardroom, recessed lights labeled as D will need to be separated into their own zone to turn them off when the monitor is on. This will prevent glare and reflections on the screen, ensuring a clear and visible display. Axis Technology Specialist documentation supports the necessity of proper lighting control in AV installations to optimize viewing conditions.

• Question 115:

  What would be the BEST way to verify proper performance of a CAT cable fitted with a new termination?

  A. use a cable tester and run a protocol
  B. use a multimeter to test if the pins have a connection
  C. connect the cable to a reference unit to check against it
  D. connect the source and sync, then verify there is a picture
  A. use a cable tester and run a protocol

  ---

  Explanation

  Using a cable tester and running a protocol is the best way to verify the proper performance of a CAT cable with a new termination. Cable testers can check for continuity, wiring configuration, signal quality, and performance standards compliance (e.g., Cat 5e, Cat 6). They can detect faults such as open circuits, short circuits, and incorrect wiring, ensuring the cable is terminated correctly and capable of supporting the desired network speeds and protocols.

• Question 116:

  HOTSPOT

  Which section of the Ohm's Law chart should be used to calculate values expressed in Ohms?

  Select the answer by clicking anywhere within the correct quadrant.

  

  

  ---

  Ohm's Law is a fundamental principle used in electrical engineering and physics to describe the relationship between voltage (V), current (I), resistance (R), and power (P). The Ohm's Law chart is divided into four quadrants, each representing different formulas and relationships among these quantities. To calculate values expressed in Ohms (which represent resistance, R), you should use Quadrant D. This quadrant contains formulas that solve for resistance (R), using various combinations of voltage (V), current (I), and power (P):

  R=VIR = \frac{V}{I}R=IV

  R=V2PR = \frac{V^2}{P}R=PV2

  R=PI2R = \frac{P}{I^2}R=I2P

  These formulas are derived from Ohm's Law and the power equations, providing different ways to calculate resistance based on the available information.

  Ohm's Law: Explains the relationship between voltage, current, and resistance. Power Formulas: Derived from the basic Ohm's Law equations and used to relate power with resistance, voltage, and current.

  To further verify and detail the usage of Ohm's Law chart, you can refer to Axis Technology Specialist documentation or any standard electrical engineering textbooks which provide detailed explanations of these formulas and their applications.

• Question 117:

  After field changes are made during installation, which documentation should be updated before project closeout?

  A. As-built drawings, cable labels or schedules, IP information, configuration notes, and operation or maintenance documents.
  B. Only the original proposal, because field changes should not appear in technical records.
  C. Only the client's marketing brochure for the room.
  D. Only the invoice total, without recording what changed.
  A. As-built drawings, cable labels or schedules, IP information, configuration notes, and operation or maintenance documents.

  ---

  Explanation

  Closeout documentation should describe the system as it was actually installed. Updated drawings, cable schedules, labels, addresses, configuration notes, and operating or maintenance information help the client operate and service the room. Leaving records at the original design state makes future support slower and less accurate.

• Question 118:

  Which agreement typically includes installation materials and workmanship against failure for a stipulated period after the installation is complete?

  A. Service warranty
  B. System warranty
  C. Preventive warranty
  D. Manufacturer's warranty
  B. System warranty

  ---

  Explanation

  A system warranty is provided by the AV integrator and covers the entire installed system, including materials and workmanship, for a specified period post-installation. This ensures that any issues arising from the installation process are addressed without additional cost to the client.

• Question 119:

  Which frequencies are amplified by a subwoofer?

  A. lowest
  B. mid-low
  C. mid-high
  D. highest
  A. lowest

  ---

  Explanation

  Subwoofers are designed to amplify the lowest frequencies, typically ranging from about 20 Hz to 200 Hz. These low-frequency sounds are crucial for producing deep bass tones in audio systems, enhancing the overall listening experience by providing a richer and fuller sound.

• Question 120:

  Which requirement supersedes others when planning an AV project for a client?

  A. Institutional policies
  B. Existing infrastructure
  C. Organizational standards
  D. Local safety ordinances and building codes
  D. Local safety ordinances and building codes

  ---

  Explanation

  While institutional policies, existing infrastructure, and organizational standards are important considerations in AV project planning, local safety ordinances and building codes are legal requirements that must be adhered to. Non-compliance can result in legal penalties, project delays, or safety hazards.

  Therefore, they take precedence over other considerations.
