Network Defense Essentials (NDE) Practice Exam

What IoT function ensures data is not lost or corrupted during processing?

1. Batch processing

2. Streaming data processors

3. Data validation mechanisms

4. Cloud computing resources

The correct answer is: Streaming data processors

The selection of streaming data processors as the correct answer relates to how these systems handle data in real-time, allowing for the continuous processing of information as it is generated. This is particularly important in Internet of Things (IoT) applications, where devices often transmit data continuously or in rapid bursts. Streaming data processors are designed to manage this influx of data, processing it as it arrives to minimize latency and ensure that data integrity is maintained. By utilizing techniques such as windowing, filtering, and aggregating, these processors can effectively handle high volumes of data while making sure that it does not get lost or corrupted during processing. Additionally, they often incorporate mechanisms for error detection and correction, enhancing reliability in data transmission. In contrast, while batch processing can handle large quantities of data, it typically processes data at intervals rather than in real-time, which may lead to potential data loss if not handled carefully. Data validation mechanisms are crucial for ensuring that the data being processed meets certain standards and is correct, but they don't inherently prevent data loss or corruption during the processing stage itself. Cloud computing resources provide scalable infrastructure for data storage and processing but do not specifically ensure data integrity during processing.
