Comprehensive and Detailed Explanation From Exact Extract:
Pega’s asynchronous processing tools, including Data Flows and Queue Processors, serve distinct purposes, as explained in Pega Academy’sLead System Architect Missionand thePega Certified Lead System Architect Study Guide. Data Flows are designed for processing large datasets, often in batches, while Queue Processors handle individual items with immediate or queued processing.
Option A (Correct): Queue Processors can process a single item immediately (e.g., via Standard or Dedicated queues), making them suitable for real-time, event-driven tasks. Data Flows, however, are designed for processing streams or batches of data and do not handle single items with the same immediacy. This distinction is highlighted in theData Flow vs. Queue Processorsection of Pega Community.
Option B (Incorrect): Both Data Flows and Queue Processors can process data asynchronously. Data Flows support asynchronous batch processing, and Queue Processors handle queued tasks asynchronously, making this statement false, per theAsynchronous Processingmodule.
Option C (Incorrect): Data Flows are not typically scheduled to run at specific times; they are triggered by data sources or events. Job Schedulers, not Data Flows, are used for scheduled tasks. Queue Processors also run based on queue triggers, not schedules, as noted in theData Flow Configurationmodule.
Option D (Incorrect): Data Flows are specifically designed to process large volumes of data, such as in analytics or ETL processes, while Queue Processors are better suited for smaller, individual tasks. This makes the statement incorrect, per theLead System Architect Mission.
