Multiple Choice

Which of the following is not typically used for IoT communication?

• ZigBee

• Wireless Sensor Networks (WSN)

• RSA Encryption

• IPv6

​Communication architecture used in ZigBee

Multiple Choice

True or False - Standard communication protocols are ideal for IoT devices because they work well with energy-saving modes and dynamic networks.

• True

• False

Multiple Choice

In an IoT data mining process, suppose we have a model:

A = B + C + D + E

If D and E are strongly correlated and represent similar behaviors, parameter reduction would most likely simplify the model to:

• A = B + C + D + E

• A = B + D + E

• A = B + C + D

• A = C + D + E

Multiple Choice

In the Fog-to-Cloud model, the Fog layer handles _______ tasks close to the data source, while the Cloud layer is responsible for _______ processing and analytics.

• heavy / real-time

• long-term / fast

• real-time / heavy

• remote / mobile

Multiple Choice

Which of the following statements best describes the IoT system development process?

• IoT systems are developed using only hardware optimization techniques.

• IoT development follows a strict linear process with no iterations.

• IoT systems use ER models and SysML for data modeling and follow a feedback-oriented, iterative workflow.

• IoT system development excludes the use of conventional modeling tools like UML or ER diagrams.

Multiple Choice

What does “serverless” actually mean in modern cloud computing?

• There are no servers involved in executing the application.

• The application runs entirely on the user's device without any backend.

• The servers are automatically managed by a cloud provider, so developers don’t need to manage infrastructure.

• The application can only be used offline.
