**Question 1.** Which stakeholder group is primarily responsible for defining the functional
requirements of a new AV system?
A) Facility management
B) End-users
C) IT security team
D) Project sponsor
Answer: B
Explanation: End-users interact with the system daily and therefore dictate what functions it must
perform.
**Question 2.** During a site survey, the measurement of reverberation time (RT60) is most relevant to
which design consideration?
A) Power distribution layout
B) Acoustic treatment planning
C) Network cabling pathways
D) Structural load calculations
Answer: B
Explanation: RT60 indicates how long sound persists in a space, guiding acoustic treatment decisions.
**Question 3.** Which document lists every piece of hardware, software, and accessory required for a
project?
A) Signal flow diagram
B) As-built drawing
C) Bill of Materials (BOM)
D) Project schedule
Answer: C
Explanation: The BOM details all components needed for procurement and installation.
**Question 4.** What is the primary purpose of a reflected ceiling plan (RCP) in AV design?
, ITGSS Certified Technology Specialist
Ultimate Exam
A) Show cable conduit locations
B) Indicate placement of ceiling-mounted devices
C) Detail floor-level power outlets
D) Outline network switch locations
Answer: B
Explanation: An RCP displays where speakers, projectors, or other ceiling-mounted equipment will be
installed.
**Question 5.** Which mounting method is recommended for a 150-lb LED wall panel on a suspended
ceiling?
A) Standard drywall anchor
B) Ceiling grid clip with rated load capacity
C) Adhesive strip
D) Freestanding floor stand
Answer: B
Explanation: Ceiling grid clips rated for the panel’s weight ensure safe, secure mounting.
**Question 6.** When routing HDMI cables over 30 m, which technology should be used to maintain
signal integrity?
A) Passive HDMI cable
B) HDMI over Ethernet extenders (HDBaseT)
C) Fiber-optic HDMI cable only up to 10 m
D) Coaxial balun adapters
Answer: B
Explanation: HDBaseT extenders transmit HDMI signals over Cat5e/6 up to 100 m with full bandwidth.
**Question 7.** In a VLAN configuration for an AV system, which VLAN is typically used to isolate
control traffic from video streams?
A) VLAN 10 – Data
, ITGSS Certified Technology Specialist
Ultimate Exam
B) VLAN 20 – Voice
C) VLAN 30 – Management
D) VLAN 40 – AV Control
Answer: D
Explanation: A dedicated AV Control VLAN keeps control commands separate from other network traffic.
**Question 8.** Which security protocol provides the strongest wireless protection for AV devices?
A) WPA2-PSK
B) WPA3-Enterprise
C) WEP
D) Open (no encryption)
Answer: B
Explanation: WPA3-Enterprise offers robust authentication and encryption, surpassing WPA2-PSK.
**Question 9.** An HDMI source displays a black screen on a 4K display. Which setting is most likely
causing the issue?
A) Incorrect IP address on the display
B) Mismatched EDID resolution
C) Unconfigured VLAN ID
D) Outdated firmware on the power supply
Answer: B
Explanation: If the source’s EDID does not match the display’s native resolution, the display may refuse
the signal.
**Question 10.** What does HDCP protect against in an AV installation?
A) Unauthorized network access
B) Content piracy by preventing copying of protected video
C) Physical tampering of cables
, ITGSS Certified Technology Specialist
Ultimate Exam
D) Audio feedback loops
Answer: B
Explanation: HDCP encrypts digital video to stop illegal copying of copyrighted content.
**Question 11.** Which tool is most appropriate for calibrating color accuracy on a professional video
wall?
A) Spectrum analyzer
B) Colorimeter (e.g., X-Rite i1Display)
C) Sound pressure level meter
D) Multimeter
Answer: B
Explanation: A colorimeter measures display color output and creates calibration profiles.
**Question 12.** In DSP programming, what does “echo cancellation” primarily address?
A) Reducing background HVAC noise
B) Removing delayed reflections that cause echo in speech
C) Balancing speaker levels across zones
D) Limiting audio clipping
Answer: B
Explanation: Echo cancellation algorithms detect and subtract delayed audio copies that cause echo.
**Question 13.** Which scheduling technique helps avoid conflicts with electrical trades during AV
installation?
A) Critical Path Method (CPM)
B) Gantt chart with trade-specific milestones
C) Agile sprint backlog
D) Kanban board without dates
Answer: B
