Free Practice Questions for CWNP CWISA-102 Exam

Signal Strength and Data Rate: In wireless links, weaker signal strength often directly correlates to reduced transmission speeds. Modern wireless technologies use adaptive modulation and coding, sacrificing speed for reliability when signals become weaker.

Noise and Interference: While these can impact performance, they don't inherently decrease simply because signal strength drops.

Latency: Latency can be affected by poor signal, but its primary drivers are distance and network congestion.

Modulation and Coding Schemes (MCS): Technical descriptions of how Wi-Fi and other wireless technologies adjust speeds based on signal quality.

Smart Building Core Benefit: Smart building technologies primarily aim to optimize a building's operational efficiency through automation and data-driven insights.

Efficiency Examples:

Energy Management: Automated lighting and HVAC control based on occupancy and environmental conditions.

Maintenance: Predictive maintenance through IoT sensors reduces downtime.

Space Utilization: Optimization of space allocation based on real-time usage patterns.

Articles on Benefits of Smart Buildings: A quick search will yield many resources detailing these advantages.

Privilege Creep Defined: Gradual accumulation of excessive permissions over time, often due to users changing roles or access needs not being adjusted accordingly.

Other Terms:

Privilege Escalation: A malicious act of obtaining higher-than-authorized access.

Improper Delegation/Grouping: Faulty permission assignment, but not the gradual accretion aspect.

References:

Principle of Least Privilege: Security best practice emphasizing the need to minimize access to only what's necessary.

Access Control Models: Discussions of how privilege creep can violate security principles.

Lab Purpose: Wireless testing labs offer controlled settings to:

Skill Development: Hone practical understanding of wireless technologies without impacting production environments.

Experimentation: Safely test different configurations, compatibility, and potential issues.

Troubleshooting: Isolate problems, test solutions, and understand how equipment behaves in various scenarios.

Other Benefits (While not the primary benefit):

Learning Environment: Ideal for structured training and exploration.

Evaluation: Compare hardware performance before deployment.

Benefits of IT Labs: Can be extended from wireless to broader IT experimentation and learning. (Articles on this topic are readily available)

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:

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

Many languages work in web or command line, not both like PHP.

PHP (Introduction): Overviews mentioning its dual role in server-side web applications and as a general-purpose scripting language.

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

IEEE's Role: The Institute of Electrical and Electronics Engineers (IEEE) is a global organization critical in developing and promoting technical standards across various fields, including wireless technologies.

Standards Work: IEEE creates wireless technology standards like:

IEEE 802.11: Wi-Fi standards

IEEE 802.15.4: Basis for ZigBee, Thread, and other low-power networks

Outsourcing Knowledge Transfer: When outsourcing implementation, the service provider has firsthand knowledge of system setup and configuration. Clear documentation ensures this knowledge remains accessible to you after the project is complete.

Ongoing Support: While paid/free support options influence long-term maintenance, they won't substitute missing documentation about the specific setup.

Reducing Future Vendor Reliance: Detailed documentation helps mitigate over-reliance on the service provider for minor changes and troubleshooting, giving you more long-term autonomy.

Proof of Concept: A POC typically happens before outsourcing, and focuses on validating the solution's feasibility, not ensuring smooth knowledge transfer thereafter.

References:

Service Level Agreements (SLAs): Documentation related to outsourced work may be defined as a deliverable within an SLA.

Knowledge Management Best Practices:

BLE Beacon Power Efficiency: Bluetooth Low Energy (BLE) beacons are designed for low power consumption. Their primary function is to periodically broadcast short data packets (advertising their presence).

Other Technologies:

Cellular: More power-hungry due to long-range communication and complex protocols.

GPS: Power intensive, especially when actively tracking location.

Wi-Fi:

XAML and .NET: XAML (eXtensible Application Markup Language) is primarily used within the .NET framework for defining user interfaces. Specifically, technologies like:

WPF (Windows Presentation Foundation): Desktop application UIs

Xamarin: Mobile app UIs

XAML in Other Frameworks: While some limited adaptation exists, its core use is tightly coupled with .NET technologies.

XAML Overview (Microsoft Docs): Introductions to XAML emphasizing its use in .NET applications.

WPF Documentation: Tutorials and references specifically mentioning XAML's role in Windows desktop development.

LoRa: Refers to the physical layer chirp spread spectrum (CSS) modulation, enabling long-range, low-power communication.

LoRaWAN: An open MAC layer protocol that builds on LoRa, defining network architecture, device management, and data routing for large-scale LoRa networks.
