Introduction
The North Carolina Wireless Networking Certification assessment is designed to validate the technical
competency, regulatory knowledge, and analytical skills required of wireless engineering professionals
operating within the state. This comprehensive examination evaluates proficiency in radio frequency
mathematics, secure infrastructure deployment, state-specific legal compliance, and ethical standard
adherence. Utilizing a combination of foundational knowledge assessment and complex, scenario-based
situational questions, the exam emphasizes real-world application and critical decision-making.
Candidates must demonstrate a thorough understanding of advanced wireless protocols, localized
structural codes, and data privacy mandates to ensure the delivery of resilient, secure, and legally
compliant enterprise wireless architectures.
Section One: Questions 1–100
Question 1
,An administrator in a Raleigh corporate office is troubleshooting a sudden drop in throughput on a 2.4
GHz 802.11n network. A spectrum analyzer reveals high, continuous non-Wi-Fi energy across the entire
frequency range of channel 6. Which of the following is the most likely source of this interference?
A. A neighboring corporate network operating on channel 11
B. An active commercial microwave oven in the breakroom
C. A malfunctioning 5 GHz corporate access point
D. A local Bluetooth headset pairing session
🟢 B. An active commercial microwave oven in the breakroom
🔴 RATIONALE: Commercial microwave ovens operate within the 2.45 GHz band and emit significant,
continuous non-Wi-Fi RF energy when active. This radiation frequently disrupts the entire width of
channel 6 (and adjacent frequencies), severely degrading throughput. Neighboring Wi-Fi networks cause
co-channel or adjacent-channel interference rather than continuous non-Wi-Fi energy, while Bluetooth
uses frequency-hopping spread spectrum (FHSS) which appears as intermittent narrow bands rather
than a solid block of continuous interference across a full 20 MHz channel. 5 GHz access points operate
in an entirely different frequency band.
Question 2
Under North Carolina General Statutes Chapter 132 (Public Records), a state agency deploying a public
guest wireless network must handle user connection logs with which of the following considerations?
A. Connection logs are completely exempt from public inspection under all circumstances to protect user
privacy.
B. Connection logs are considered public records unless they contain specific descriptive information
protected under narrow statutory exemptions.
C. All connection logs must be automatically deleted within 24 hours to avoid creating a public record.
D. Connection logs must be published on a public index monthly according to federal transparency laws.
🟢 B. Connection logs are considered public records unless they contain specific descriptive information
protected under narrow statutory exemptions.
,🔴 RATIONALE: Under NC G.S. Chapter 132, data collected by public agencies, including network
connection logs, generally falls under the definition of public records. However, narrow exemptions exist
to protect sensitive identifying information, network security infrastructure details, or personally
identifiable information (PII). Automatic deletion or complete exemption without statutory backing violates
the public records act.
Question 3
An engineer is designing a wireless bridge between two buildings in Charlotte that are 3 miles apart. To
calculate the total path loss and ensure line of sight (LOS), what percentage of the first Fresnel zone
must be kept clear of obstructions at a minimum?
A. 20%
B. 40%
C. 60%
D. 100%
🟢 C. 60%
🔴 RATIONALE: For a long-distance RF line-of-sight link to operate efficiently without significant
attenuation, at least 60% of the first Fresnel zone must be completely free of obstructions. Any further
blockage introduces significant phase cancellation and signal degradation due to diffraction.
Question 4
A wireless network technician is deployed to assist a North Carolina municipal utility provider. The
technician notices that the utility's outdoor access points are mounted directly to electrical poles without
proper grounding conductors. Which code dictates the specific grounding and bonding requirements for
this equipment?
A. FCC Part 15
B. National Electrical Code (NEC) Article 810
C. IEEE 802.11ac Standard
D. North Carolina Building Code Chapter 1
🟢 B. National Electrical Code (NEC) Article 810
, 🔴 RATIONALE: NEC Article 810 specifically covers radio and television equipment, including wireless
access points and antennas mounted outdoors. It outlines the precise requirements for grounding
conductors, bonding, and lightning surge arrestors to prevent electrical hazards. FCC Part 15 regulates
low-power unlicensed transmitters but does not govern electrical safety installation codes.
Question 5
A network engineer needs to implement an authentication mechanism for an enterprise Wi-Fi network
that requires mutual authentication using digital certificates on both the client side and the authentication
server. Which EAP type should be selected?
A. EAP-TLS
B. EAP-TTLS
C. PEAPv0/EAP-MSCHAPv2
D. EAP-FAST
🟢 A. EAP-TLS
🔴 RATIONALE: Extensible Authentication Protocol-Transport Layer Security (EAP-TLS) requires both
the authentication server and the client device to possess valid digital certificates, establishing a robust
mutual authentication architecture. EAP-TTLS and PEAP typically only require a server-side certificate,
authenticating the client via inner methods like usernames and passwords.
Question 6
During a site survey in a manufacturing facility in Greensboro, an engineer records a signal-to-noise ratio
(SNR) of 10 dB on an access point servicing a critical barcode scanner. What is the most immediate
consequence of this SNR level on the scanners?
A. The scanners will seamlessly roam to another access point.
B. The scanners will experience high packet retransmissions and frequent disconnections.
C. The scanners will automatically increase their internal antenna gain.
D. The scanners will switch from 2.4 GHz to 5 GHz operation exclusively.
🟢 B. The scanners will experience high packet retransmissions and frequent disconnections.
