Get CWNP CWISA-103 Exam Practice Questions - Real and Updated

Answer : A

Perception Layer:The foundation of an IoT system, it consists of sensors and actuators that:

Sense:Collect data about the environment or object being monitored.

Actuate:Potentially make changes based on commands (e.g., a smart valve opening/closing).

Transmit:Send gathered data to upper layers for processing.

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 : C

WWAN (Wide-Area Wireless Network):WWANs provide connectivity over extensive geographic areas, typically covering regions or even entire countries.

Cellular Technology:WWANs often rely on cellular networks (3G, 4G, 5G) offered by mobile carriers.

Answer : C

OFDM vs. OFDMA:

OFDM (Orthogonal Frequency-Division Multiplexing):Divides a channel into multiple subcarriers for data transmission.

OFDMA (Orthogonal Frequency-Division Multiple Access):Extends OFDM by allowing multiple users to share subcarriers simultaneously, improving efficiency and spectral utilization.

Answer : A

Most Vulnerable In Transit:Sensitive data (passwords, health information, etc.) is most susceptible to interception while being sent over a wireless network. Encryption is crucial at this stage.

Encryption at Rest and in Memory:While also important, these are often handled with different cryptographic techniques depending on the system.

Wireless Security Protocols:Details on encryption standards like WPA2/WPA3, TLS that focus on protecting data during transmission.
