Ethical Hacking Essentials Practice Test

Which of the following cloud services provides data processing services such as IoT services for connected devices, mobile and web applications, and batch-and-stream processing?

1. Function-as-a-Service

2. Infrastructure-as-a-Service

3. Software-as-a-Service

4. Platform-as-a-Service

The correct answer is: Function-as-a-Service

The correct answer is the service model that focuses on providing a platform for developers to build, deploy, and manage applications without needing to handle the underlying infrastructure. This model of cloud service enables data processing capabilities that are essential in scenarios such as Internet of Things (IoT) applications, mobile and web applications, and various forms of batch and stream data processing. Function-as-a-Service, while useful for executing code in response to events, does not encompass the broader array of data processing services indicated in the question, such as those needed for IoT or comprehensive application hosting. The other options, like Infrastructure-as-a-Service, typically provide virtualized computing resources without the higher-level data processing functions that come with a more robust platform. Software-as-a-Service focuses on delivering software applications over the internet rather than providing a backend for processing data. Similarly, Platform-as-a-Service is specifically designed to provide the environments needed for IoT services and web applications as well, which also demonstrates versatility in handling data flows. Understanding this helps recognize how different cloud service models facilitate various layers of application and data management, showing the essential role of Platform-as-a-Service in enabling developers to harness complex data processing without managing the underlying hardware themselves.
