AAIA Exam Topic 5 Question 40 Discussion:
Question #: 40
Topic #: 5
An IS auditor is auditing a financial system in which a generative AI tool is used to identify trends in batches of 4,000 rows, while the generative AI tool has a limit of 3,000 tokens. Which of the following is the GREATEST concern?
A.
The AI will process only a portion of the data set.
B.
The AI will prioritize high-value entries.
C.
The AI will reject the data set and not analyze the data.
D.
The AI output will be biased toward the first 3,000 tokens.
Generative AI tools such as large language models often have token limitations that restrict how much input they can process in a single prompt. According to the AAIA™ Study Guide, when input exceeds token limits, the model processes only the initial portion—leading to biased outputs based on early entries.
“Token limits in generative AI systems may lead to partial input processing, skewing model outputs toward the beginning of the data and introducing interpretive bias. Auditors must assess whether output reflects the full dataset.”
Options A and C describe side effects, but D identifies the most significant risk—output distortion due to truncated input.
