CWNP Certified Wireless IoT Solutions Administrator (2025 Edition) CWISA-103 Exam Questions

Answer : B

IEEE 802.15.4:The IEEE 802.15.4 standard is a fundamental specification for low-rate wireless personal area networks (LR-WPANs). It serves as the basis for many wireless IoT protocols.

IEEE's Role:The Institute of Electrical and Electronics Engineers (IEEE) is the organization responsible for creating, maintaining, and publishing the 802.15.4 standard.

Answer : D

Smart City Focus:Smart city initiatives mainly address infrastructure, environmental monitoring, and optimization of public services.

Ride-sharing Context:While self-driving technologycouldcontribute to future smart city transportation, it's primarily a private-sector innovation, not a core municipal service like the other options.

Typical Smart City Applications:

Wi-Fi: Provides public internet access, enabling data collection

Pollution Monitoring: Tracks air/water quality for environmental management.

Demand-based Tolling: Adjusts pricing for traffic management.

Smart City Examples:Case studies showcasing common application areas (infrastructure, environment, utilities).

Autonomous Vehicles and Smart Cities:Discussions of the potential interplay but emphasize the still-developing nature of self-driving tech.

Answer : D

Overlay vs. Integrated Monitoring:

Overlay:A separate monitoring system independent of the primary wireless infrastructure.

Integrated:Monitoring functions built into wireless access points or controllers.

Overlay Advantage:Since the overlay system is separate, it doesn't add overhead or complexity to the core network, avoiding potential disruption of wireless services.

Answer : C

Health IoT Device Categories:

Wearable:Devices worn on the body (smartwatches, fitness trackers).

Non-wearable:Devices used without being worn (smart scales, connected medical equipment).

Implantable:Surgically inserted devices (pacemakers, glucose monitors).

Reference

Health IoT:Resources on healthcare + IoT will illustrate device types.

Answer : D

Requirements Drive Decisions:The decision between wired or wireless must align with the solution's overall purpose, performance targets, and operational constraints.

Key Considerations:

Reliability:Does the application require guaranteed connectivity? (Wired may be favored).

Installation Cost:Can extensive cabling be done, or is it prohibitively expensive? (Wireless may be favored).

Flexibility and Scalability:Is node placement likely to change in the future? (Wireless may be favored).

Other Factors are Important, But Secondary:Distance, PoE availability, specific applications all matter, but they are assessedwithin the contextof the overarching business needs.

Wireless vs. Wired Network Design:Comparisons of pros and cons, highlighting how use cases guide the choice.

IoT Solution Planning:Materials on defining requirementsbeforeselecting technology.

Answer : B

Wi-Fi and Zigbee Interference:Both can operate in the 2.4 GHz band, leading to potential interference that degrades performance for both networks.

5 GHz Advantages:

Less crowded: Fewer devices operate in the 5 GHz band, reducing interference potential.

Wider Channels: 5 GHz supports wider channels, enabling higher data throughput for Wi-Fi.

Answer : A

IIoT Environments:Industrial IoT (IIoT) often involves deployment in harsh environments (factories, plants, outdoor sites) with:

Extreme temperatures

Dust & Vibrations

Exposure to chemicals or moisture

Ruggedization:IIoT devices are designed to withstand these conditions, ensuring reliability and longevity.
