The correct answer is to increase the heap memory for the processing application. This resolves the OutOfMemoryError because the Java Virtual Machine (JVM) runs out of heap space when handling large CSV files, and raising the heap limit—typically via the -Xmx flag—gives the data pipeline enough room to load and process the entire dataset without crashing. On the Salesforce AI Associate exam, this question tests your understanding of resource allocation in data pipelines, often appearing as a scenario where a pipeline fails intermittently under heavy load. A common trap is to assume the fix involves optimizing the CSV parsing code or reducing file size, but the direct cause is insufficient JVM memory, not logic errors. Remember the mnemonic “Heap High for Heavy Files” to recall that when you see OutOfMemoryError with large CSVs, the first step is to increase heap memory, not rewrite the pipeline.

This AI Associate practice question tests your understanding of data for ai. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A data pipeline fails intermittently when processing large CSV files. The error log shows 'OutOfMemoryError'. Which configuration change is most likely to resolve this?

Correct answer & explanation
✓
Increase the heap memory for the processing application.
The OutOfMemoryError indicates that the Java Virtual Machine (JVM) heap space is exhausted while processing large CSV files. Increasing the heap memory (e.g., using -Xmx flag) allocates more memory to the application, allowing it to handle larger datasets without crashing. This directly addresses the root cause of insufficient memory for the data pipeline's processing workload.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
Use a smaller file size limit.
Why it's wrong here
While it might avoid the error, it doesn't solve the underlying memory problem and could lead to data loss.
✗
Increase the number of worker threads.
Why it's wrong here
More threads increase memory contention and may worsen the issue.
✗
Switch to XML format.
Why it's wrong here
XML is more verbose and would increase memory usage, not decrease.
✓
Increase the heap memory for the processing application.
Why this is correct
Increasing heap memory provides more space for large file processing.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Salesforce often tests the misconception that increasing parallelism (worker threads) solves memory issues, but in reality, more threads increase memory pressure and can trigger OutOfMemoryError faster.
Detailed technical explanation
How to think about this question
The JVM heap is divided into generations (Young, Old, and Metaspace), and OutOfMemoryError often occurs when the Old generation cannot accommodate new objects after full garbage collection. In data pipelines processing large CSV files, each row is typically parsed into objects that reside in heap memory; tuning heap size with -Xms and -Xmx, along with garbage collector selection (e.g., G1GC), can improve throughput. Real-world scenarios often involve streaming or chunked processing to reduce memory footprint, but increasing heap is the simplest configuration fix for a memory-bound application.

TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the AI Associate exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
