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

Answer : B

Captive Portals for Guest Access:These are web pages that intercept users' requests before granting full internet access. They often require agreeing to terms, entering basic information, or viewing ads.

Hospitality Fit:Captive portals are simple to deploy, require minimal user setup, and provide control for the hospitality provider (e.g., usage limits).

Why Other Options Are Less Common:

NTLM:Microsoft authentication, mainly for corporate networks, too complex for casual guest use.

Kerberos:Complex authentication for enterprise, overkill for guest Wi-Fi

SIM Cards:Used in cellular devices, not for general Wi-Fi access.

Captive Portals:Explanations of how they work and their use cases.

Guest Wi-Fi in Hospitality:Best practices highlight the prevalence of captive portals in this industry.

Answer : B

LoRa:This refers to the underlying radio modulation technique using Chirp Spread Spectrum (CSS). It defines how data is physically encoded onto the wireless signal.

LoRaWAN:This is the network protocol built on top of LoRa. It manages device communication, network topology, and aspects like security. It operates at the MAC sublayer of the Data Link layer (Layer 2) of the OSI model

LoRa vs. LoRaWAN:Key takeaway is that LoRa is the physical layer technology, while LoRaWAN adds the networking layer for management.

LoRa Modulation:Technical explanations of Chirp Spread Spectrum (CSS).

LoRaWAN Specification:Official documentation detailing the network architecture and MAC layer functions.

OSI Model:Descriptions of the Data Link layer and its role in networking.

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 : 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.

Rugged Devices:Articles on ruggedized electronics will emphasize their importance in industrial settings.

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

IP Ratings & Manufacturing:IP66 provides:

Dust-tight:(First '6') Complete protection against dust ingress.

Powerful Water Jets:(Second '6') Protection against strong water jets from any direction.

Harsh Manufacturing Environments:IP66 is common due to dust, dirt, and potential exposure to liquids during cleaning or spills.

Answer : B

Purpose of POC:A proof-of-concept (POC) validates the feasibility and potential value of a solution within its intended operational environment.

Scaling:POCs are small-scale,allowing for quicker and less costly testing before committing to a full-scale deployment.

Real-world Evaluation:Unlike manufacturer demos,a POC exposes the system to the unique variables (e.g.,interference,usage patterns) present in the user's specific setting.

IT project management:Materials discussing the role of proof-of-concept phases and their goals.
