AVIXA AVIXA-CTS Online Questions & Answers

• Question 151:

  One MAIN benefit of multicast over unicast in a network AV solution is it.

  A. supports multi-channel audio.
  B. supports higher video resolutions.
  C. reduces network bandwidth whenusing multipleencoders.
  D. reduces network bandwidth whenusing multipledecoders.
  D. reduces network bandwidth whenusing multipledecoders.

  ---

  Explanation

  Multicast transmission in a network AV solution significantly reduces network bandwidth when using multiple decoders. With multicast, a single stream of data is sent from the source and is then distributed to multiple recipients by the network infrastructure. This contrasts with unicast, where a separate stream is sent to each recipient, leading to higher bandwidth consumption. Multicast is particularly efficient in scenarios where the same content needs to be delivered to multiple devices, such as digital signage or IPTV.

• Question 152:

  A client has ordered a large project from a company. This project has several critical components and a fixed schedule.

  Which of the following will be VITAL for ensuring that the company meets the deadlines?

  A. proper job costing
  B. confirming lead times
  C. qualifying the customer
  D. confirming price changes
  B. confirming lead times

  ---

  Explanation

  For a project with several critical components and a fixed schedule, confirming lead times is vital. Lead times refer to the amount of time it takes for components to be delivered from the supplier to the project site. By confirming and managing lead times, the company can ensure that all necessary components arrive on time, preventing delays and enabling the project to proceed according to the planned schedule. This is essential for meeting deadlines and ensuring project success.

• Question 153:

  What should be identified during a project's needs analysis?

  A. the overall budget
  B. stakeholders involved
  C. the timeline for completion
  D. key activities to be performed
  B. stakeholders involved

  ---

  Explanation

  A needs analysis should identify all stakeholders involved, as they influence project requirements, decision-making, and the approval process. Understanding stakeholders ensures that all perspectives are considered, leading to a more comprehensive solution.

  CTS Technology Specialist Reference

  CTS guidelines stress identifying stakeholders early to ensure project alignment with all key parties and address specific needs or preferences.

• Question 154:

  What frequency is identified by the numbers above each slider of a graphic equalizer?

  

  A. center
  B. lowest
  C. highest
  D. secondary
  A. center

  ---

  Explanation

  The frequency identified by the numbers above each slider of a graphic equalizer is the center frequency. The center frequency is the specific frequency that each slider controls, allowing the user to boost or cut the amplitude of that frequency and those in its immediate vicinity. This helps in fine-tuning the audio signal to achieve the desired sound quality.

  Audio equipment manuals and equalizer usage guidelines, such as those from Axis Communications and other audio equipment manufacturers, explain the function of center frequencies in graphic equalizers.

• Question 155:

  Which connector is typically used for ease of termination for various signal types?

  

  A. A
  B. B
  A. A

  ---

  Explanation

  Connector A is a BNC (Bayonet Neill-Concelman) connector, which is commonly used for a variety of signal types, including video (such as composite and SDI), RF signals, and even some data signals. It is known for its ease of termination, with a simple twist-lock mechanism that ensures secure and quick connections. The BNC connector's versatility and reliability make it popular in professional AV environments. Connector B is a VGA (Video Graphics Array) connector, typically used for analog video signals, particularly between computers and monitors. However, VGA connectors are not typically associated with ease of termination due to their multiple pins and more complex soldering requirements compared to the quick-connect design of BNC connectors.

  CTS Technology Specialist Reference

  The CTS curriculum highlights BNC connectors as versatile and easy-to-use, suitable for a range of AV signal types. Their locking mechanism and straightforward assembly process make them a preferred choice for AV professionals needing quick and reliable connections across various applications.

• Question 156:

  The circuit on the RIGHT is an electrical drawing of what type of speaker system?

  

  A. series circuit
  B. constant voltage
  C. stereo pair circuit
  D. combination parallel/series circuit
  D. combination parallel/series circuit

  ---

  Explanation

  The circuit on the right is a combination parallel/series circuit. In this configuration, two sets of speakers are connected in parallel, and these parallel sets are then connected in series. This type of arrangement allows for balancing the load across multiple speakers while maintaining the desired impedance levels.

• Question 157:

  A technician replaces a failed wall plate connector during a service call.

  What documentation best supports the repair record?

  A. Failed part description, replacement part, labor time, test result, updated label or drawing note if needed, and customer sign-off.
  B. A statement that a connector was probably changed somewhere in the room.
  C. Only a photo of the closed wall plate with no test result.
  D. Only the original installation invoice, without service details.
  A. Failed part description, replacement part, labor time, test result, updated label or drawing note if needed, and customer sign-off.

  ---

  Explanation

  Repair documentation should identify what failed, what was installed, how much labor was used, how the repair was verified, and whether records or labels changed. This supports warranty tracking, billing, future service, and customer acceptance. Vague notes or photos without test results do not establish that the issue was corrected.

• Question 158:

  Which kind of drawing should a technician refer to in order to determine how to hang a loudspeaker line array?

  A. detail
  B. section
  C. elevation
  D. reflected ceiling plan
  B. section

  ---

  Explanation

  A detail drawing provides specific, comprehensive information about particular elements of a project, such as how to hang a loudspeaker line array. These drawings include precise measurements, materials, and installation instructions, allowing technicians to understand the exact requirements and procedures for mounting the equipment. Detail drawings ensure that all aspects of the installation are clearly communicated and followed, preventing errors and ensuring a safe and effective setup.

• Question 159:

  When connecting two switches with multiple VLANs, which function should be setup in order to pass all the packets from one switch to the other?

  A. trunk line
  B. multicast routing
  C. QoS (Quality of Service)
  D. SFP (Small Form-factorPluggable)
  A. trunk line

  ---

  Explanation

  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.

• Question 160:

  Which document is used to clarify a project design issue?

  A. change order
  B. progress report
  C. request for change
  D. request for Information
  D. request for Information

  ---

  Explanation

  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.
