the caller is stating. The most appropriate action is to:
A. Trust the ALI data because it is electronically generated
B. Verify the location with the caller and follow center policy
C. Dispatch based on the ALI data immediately
D. Transfer the call to a secondary PSAP
Correct Answer: B. Standard procedure is to verify the location with the caller. ALI
data can be incorrect due to database errors or number portability issues .
2. Which transport medium uses light transmitted through glass filaments and
can only carry digital signals?
A. Copper wire
B. Coaxial cable
C. Fiber optic
D. Microwave
Correct Answer: C. Fiber optic cables transmit light through glass filaments and
provide high bandwidth with immunity to electromagnetic interference .
3. In NG9-1-1 architecture, what is the primary function of the Emergency
Services IP Network (ESInet)?
A. To provide a backup radio system for first responders
B. To route 9-1-1 calls and data over a secure, managed IP network
,C. To serve as a public-facing website for emergency information
D. To replace all landline telephone infrastructure
Correct Answer: B. The ESInet is the foundational packet-switched network for
NG9-1-1, providing secure routing of all emergency communications including
voice, text, and data .
4. What is the primary advantage of a trunked radio system?
A. All equipment is compatible with all other systems
B. Many users can independently share the same radio system
C. Channel allocation is independent of computer control
D. Only one radio channel is used for the entire system
Correct Answer: B. Trunked radio systems allow multiple user groups to share a
pool of frequencies, automatically assigning available channels as needed to
conserve spectrum .
5. A PSAP manager is evaluating the center's QA program. Scores show a high
number of errors related to gathering location information. What is the most
effective initial step?
A. Implement a punitive system for call-takers who fail to gather location data
B. Conduct a targeted training session focusing on location verification techniques
C. Remove geographic information systems from the call-taking workflow
D. Increase the number of supervisors monitoring calls in real-time
Correct Answer: B. A targeted training session directly addresses the identified
skill gap. A punitive system can be counterproductive and does not solve the root
cause .
6. A call-taker receives a TTY call but the TTY equipment is not functioning. What
should they do?
A. Hang up and assume it was a misdial
B. Use Voice Carry Over (VCO) or text-to-speech relay service
C. Transfer the call to another PSAP
D. Send a patrol unit to the ANI address
, Correct Answer: B. When TTY equipment fails, the telecommunicator should use
alternative methods such as VCO or text-to-speech relay services. Federal law
requires backup procedures .
7. The FCC regulates which of the following in the 9-1-1 context?
A. The hiring and firing practices of PSAPs
B. The internal training curriculum of each PSAP
C. Technical standards for wireless location accuracy and 9-1-1 service obligations
D. The salaries of PSAP directors
Correct Answer: C. The FCC regulates interstate communications and has
established rules regarding 9-1-1 service, including wireless location accuracy and
carrier obligations .
8. What is a "safety zone" in the context of a PSAP's workplace safety plan?
A. An area where only management is allowed
B. A physical area designated for staff to take breaks and decompress
C. A designated area for secure electronic equipment
D. A location away from the main floor for phone equipment
Correct Answer: B. A safety zone (or quiet room) is a recognized best practice for
stress management, providing a place away from the operational floor for staff to
recover from stressful incidents .
9. In a radio system, voice is converted into what form for transmission?
A. Digital pulses
B. Electrical Energy (Waves)
C. Light signals
D. Microwave radiation
Correct Answer: B. Voice is converted into electrical energy waves that travel
through the atmosphere, carrying audio information from transmitter to receiver .
10. The process of "call queuing" is used in a PSAP when:
