Free CWNP CWISA-103 Exam Actual Questions
Note: Premium Questions for CWISA-103 were last updated On Aug. 26, 2025 (see below)
What is a valid reason to continue using older wireless networking technologies?
Legacy Support:The primary reason to continue using older wireless technologies is the need to connect with devices that don't support newer standards (e.g., old sensors or equipment).
Other Reasons (Not as Strong):
Cost:Replacing legacy devices can be expensive.
Reliability:Some legacy technologies might be well-proven in specific settings.
You are performing an implementation for a cloud-based wireless solution. How is connectivity to the cloud established? (Choose the single best answer.)
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Eliminating Incorrect Options:IPX/SPX is an outdated protocol, and cellular is only one possible way to achieve Internet access.
OSI Model:Descriptions of Network Layers, especially Layer 2 (Data Link) and Layer 3 (Network).
Cloud Architecture:Diagrams showing how devices commonly access cloud resources through internet-based infrastructures.
You have implemented a wireless mesh network. All mesh nodes are properly configured for participation in the same mesh network. Several of the mesh nodes are unable to connect to other mesh nodes. What action may provide a solution to this problem?
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.
Wireless Mesh Network Troubleshooting:Guides addressing signal strength and coverage concerns.
RF Site Survey Tools:Resources on software that can help visualize signal strength and aid in node placement.
What statement best describes the difference between authentication and authorization?
Authentication:Verifying 'who' the user or device is (e.g., via passwords, certificates).
Authorization:Controlling 'what' a user or device can do once authenticated (e.g., read-only vs. read/write permissions).
Combined for Security:Both are essential. Authentication alone doesn't control access levels, and authorization without verification is meaningless.
Identity and Access Management (IAM):Articles and resources outlining the core principles of authentication and authorization.
Cybersecurity Best Practices:Guides on securing systems will often emphasize the need for both authentication and authorization controls.
In the simplified three-layer model for wireless IoT, what is the universal primary function of the Perception layer?
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.
