CWNP CWISA-102 Exam Dumps

Cloud Connectivity Relies on IP:Most cloud-based services operate via the internet, which utilizes Internet Protocol (IP) at Layer 3 of the network model.

Flexibility:Various Layer 2 technologies (Ethernet, Wi-Fi) can connect to a Layer 3 network that ultimately provides Internet access

BLE Exception:Bluetooth Low Energycanhave cloud connectivity, but often through gateways and not as a direct Layer 2 connection.

Eliminating Incorrect Options:IPX/SPX is an outdated protocol, and cellular is only one possible way to achieve Internet access.

Cloud Architecture:Diagrams showing how devices commonly access cloud resources through internet-based infrastructures.

PHP's Cross-Platform Nature:PHP originated for server-side web development, but also has a command-line interface (CLI) enabling its use for scripts and automation tasks.

Other Options:

Somelanguages are OS-specific (but less frequent with modern scripting languages) .

Many languages work in weborcommand line, notbothlike PHP.

PHP CLI:Documentation on the command-line interface for PHP.

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.

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.

Mesh Connectivity Depends on Signal:Mesh nodes relay data for each other. Weak signal strength between nodes can disrupt connectivity throughout the network.

Troubleshooting Signal Issues:Physically relocating affected nodes can improve their ability to form stable connections with other nodes in the mesh.

Why Other Options May Not Help:

Separate Mesh: Splits the network, not solving the root connectivity issue

Output Power: May help marginally, but significant improvement is typically achieved through repositioning.

Security Settings: Unlikely to cause connectivity issues between properly configured nodes in the same mesh.

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.
