Test your knowledge of technical writing concepts with these practice questions. Each question includes detailed explanations to help you understand the correct answers.

Question 21: A company is developing a garage door sensor that stores data defining when the owner is home or away and when the garage door is open or closed. The company needs to ensure the data is stored in a secure manner. What should this company be concerned about regarding the storage of user information?

Mishandling stored user information will lead to privacy issues.

Securing stored user information will affect the garage door sensor's functionality.

Connecting the garage door sensor to private networks will affect stored data.

Caching garage door sensor data at the edge will lead to governance issues.

Question 22: Which ethical issue do customers encounter when using social media platforms from their wearable IoT devices to update people about activities?

Utilizing freedom of expression at the expense of their privacy

Determining who can purchase their demographic information

Ensuring personally identifiable information being stored is secure

Making sure information is not saved locally in plain text

Question 23: A company requires customers to provide personally identifiable information (PII) when registering an IoT device. The company sells the information. A business school has argued that only people should be able to sell their information and not the IoT company. Which principle does this argument support?

Integrity must remain a high priority.

Confidentiality of all data is mandatory.

Privacy is a fundamental human right.

Availability is essential for data transfer.
