Free Certified Wireless IoT Solutions Administrator Exam CWISA-102 Exam Practice Test

What is the primary difference between LoRa and LoRaWAN

• LoRa uses RF and LoRaWAN uses light-based communications
• LoRa is the modulation method (using CSS modulation at the Physical Layer) and LoRaWAN is the MAC sub-layer of the Data Link layer
• LoRa is the Physical Layer and LoRaWAN is the Transport Layer
• LoRa is used for communicating across the Internet and LoRaWAN is used only on the local link

What metric is used to express a relative increase or decrease in signal strength?

• W
• dBm
• dB
• mW

You are planning a wireless solution deployment. The organization has several wireless solutions in use. The new deployment must coexist with these other wireless solutions. What is the most important factor to consider when implementing the new wireless solution?

• Coordinating mounting locations with the other wireless solutions
• Implementing matching encryption keys synchronized with the other wireless solutions
• Implementing contrasting encryption keys countering the other wireless solutions
• Coordinating frequency use with the other wireless solutions

What kind of PoE device can be used to power a non-PoE connected object assuming PoE power is provided on the Ethernet cable?

You are planning a wireless solution. Why should you consider an ongoing monitoring system for use after the solution is deployed?

• Implementation validation is never completed, it continues throughout the life of the system
• Monitoring the solution provides additional billable hours
• The number of users and the use of the solution will change over time and monitoring allows for detection of these changes
• To ensure that the system continues to meet the original requirements, even if users later indicate poor performance
