Test your knowledge of technical writing concepts with these practice questions. Each question includes detailed explanations to help you understand the correct answers.
Question 1: Which building block is used to move collected IoT data to the central IoT platform?
Question 2: What is the function of soil moisture sensors in a smart agriculture ecosystem?
Question 3: What moves data from IoT sensor devices to a central network?
Question 4: Which computation method processes data captured at the sensor device before sending it to a backhaul network?
Question 5: Which building block of the IoT architecture is responsible for collecting raw data generated by the monitored entity?
Question 6: Which feature characterizes a wireless local area network (WLAN) in an IoT architecture?
Question 7: What is the result of switching from the industrial, scientific, and medical (ISM) frequency above 1 GHz to the ISM frequency below 1 GHz?
Question 8: What is a short-range network technology that supports meshing?
Question 9: Itanium
Question 10: Which module in the edge computing framework is used to store IoT data received from sensors or from the cloud?
Question 11: A university is testing a smart energy solution and requires a system to monitor the following parameters of power used by its buildings: voltage, phase, apparent power, power factor, frequency. Which device should be used to perform these readings?
Question 12: A university is deploying a smart energy solution to its student dormitories and needs to collect power usage data for billing purposes. Which device should this university use?
Question 13: Standardization
Question 14: Law enforcement organizations
Question 15: Application security
Question 16: A company develops an IoT-based security system. The system uses proximity sensors that communicate with a central gateway using a 433 MHz radio signal. Testing reveals that the traffic can be sniffed with a software-defined radio, and an attacker could spoof the proximity sensor by copying the authentication details from the radio traffic. Which Internet of Things Security Foundation (IoTSF) Best Practice Guideline (BPG) should this company follow in its design process to ensure the security of the radio data?
Question 17: A company hosts a database in a public cloud. Multiple IoT devices are compromised and used to generate a high volume of requests targeting the database to affect its availability. Which type of attack is this?
Question 18: A company developed an IoT smart photo frame that allows users to upload photos to their device using a web browser. Testing revealed that users can upload files onto the root filesystem. Which Internet of Things Security Foundation (IoTSF) Best Practice Guideline (BPG) should this company follow in its design process to ensure filesystem permissions are set correctly?
Question 19: A company uses IoT devices to capture data in the field and transmit it for central processing. The company plans to follow the Internet of Things Security Foundation's (IoTSF) Best Practice Guidelines (BPGs) to ensure that personal data is protected. Which IoTSF guideline should this company use?
Question 20: Diagnostics of data quality
