NEW QUESTION # 20
An IS auditor is reviewing a dataset used by a university to train a predictive machine learning model. Which of the following MOST likely indicates risk that the model could not process all data and make necessary correlations?
- A. Having an undergraduate degree in Boolean format
- B. Grade Level field in float format
- C. Final Grade Percent field in object format
- D. Student Number field in integer format
Answer: C
Explanation:
A numeric field stored as an object (string) format (option C) indicates improper data typing. Models cannot correctly compute correlations or statistical relationships when numerical values are stored as textual data.
AAIA emphasizes that incorrect datatypes are one of the most common causes of ML model misbehavior, including:
* Failure to compute averages, correlations, or mathematical operations
* Silent errors in preprocessing
* Skewed learning patterns
* Incorrect feature importance evaluationsThus, the Final Grade Percent field in object format is the most significant indicator of processing risk.Options A, B, and D are valid datatypes for their respective fields and pose no inherent model processing risk.

NEW QUESTION # 23
Which of the following is the GREATEST risk of using AI to generate audit reports?
- A. The AI system uses inconsistent formatting across audit reports.
- B. The AI system cannot integrate with management dashboard tools.
- C. The AI system misrepresents control effectiveness.
- D. The AI system is not able to include historical audit findings.
Answer: C
Explanation:
Thegreatest riskwhen using AI to generate audit reports is that it maymisrepresent control effectiveness(B)
-for example, by overstating the robustness of controls, understating deficiencies, or summarizing findings inaccurately. This undermines the reliability of the entire audit and can lead to poor management decisions, regulatory issues, and reputational damage. AAIA emphasizes that AI-generated artifacts still require professional judgment and validationto ensure they accurately reflect audit evidence and conclusions.
Inconsistent formatting (A) and lack of integration (C) are usability and efficiency issues, not fundamental assurance risks. Inability to incorporate historical findings (D) reduces context but does not inherently misstate the current control assessment. Therefore,misrepresentation of control effectivenessis the most critical risk from an assurance standpoint.

NEW QUESTION # 24
After AI training data has been tested for biases, which of the following is MOST important to check to validate the effectiveness of the testing?
- A. AI processes will meet expected service turnaround time
- B. Feedback on data validation is obtained from key stakeholders
- C. Possible impacts from AI outputs remain within the acceptable risk level
- D. Sensitive information from users is securely masked before input
Answer: C
Explanation:
Even after identifying and mitigating bias, organizations must ensure thatAI outputs do not create unacceptable risks.
AAIA emphasizes that bias mitigation must result in:
* Fair outcomes
* Justifiable predictions
* No disproportionate harm to any demographic group
* Alignment with organizational risk tolerance
Option B reflects this requirement, ensuring that the model's real-world impact aligns with documented risk thresholds.
Option A is supportive but not validation of effectiveness.
Option C is performance-related, not fairness-related.
Option D is privacy-related, not bias-related.
Thus, confirming output impacts against risk tolerance is the most important validation step.

NEW QUESTION # 25
Which of the following is the PRIMARY advantage of using K-fold cross validation when evaluating the performance of a machine learning (ML) model?
- A. It uses multiple training and testing cycles to minimize overfitting.
- B. It helps minimize computational costs when evaluating complex models.
- C. It facilitates performing regressions on smaller data sets.
- D. It enables the reduction of model bias by setting the K variable to higher values.
Answer: A
Explanation:
The primary advantage ofK-fold cross validationis that it uses multiple train/test splits, cycling through all folds so that each observation is used both for training and testing at different points. This process provides a more reliable estimate of model performance andreduces the risk of overfitting to a single split(option D).
It is an established best practice in model evaluation and aligns with AAIA's emphasis ontesting techniques for AI solutions and data analytics.
Option A is not specific to regressions; cross validation can be used for classification and other models as well. Option B can actually increase computational cost since multiple models are trained. Option C misunderstands bias-variance trade-offs; increasing K doesn't simply "reduce model bias." The key advantage remains the use of repeated, varied splits to better assess generalization and guard against overfitting.

NEW QUESTION # 26
Which of the following is the MOST important reason to perform regular ethical reviews of AI systems?
- A. To improve the accuracy and performance of the systems
- B. To align AI system development with organizational values and principles
- C. To identify and mitigate potential data drift within models
- D. To ensure the systems align with the preservation of individual rights
Answer: D
Explanation:
The AAIA™ Study Guide reinforces that regular ethical reviews are essential to uphold human rights, prevent discriminatory outcomes, and ensure systems function within the boundaries of fairness and legality. While aligning with values (B) and preventing drift (D) are secondary benefits, the primary ethical imperative is the protection of individuals' rights and freedoms.
"Ethical reviews ensure AI systems do not violate rights related to privacy, fairness, access, and due process.
This is foundational in building public trust and avoiding legal liabilities." Option C is the clearest expression of this responsibility. Performance and alignment with values are important but secondary to ensuring human-centric safeguards.

NEW QUESTION # 29
Which of the following techniques would be MOST effective as part of incident management procedures for a prompt injection attack?
- A. Fine-tune the AI model.
- B. Monitor the prompts for excessive special characters.
- C. Deploy input validation to sanitize abuse prompts.
- D. Scan inputs for code-like structure of text.
Answer: C
Explanation:
Prompt injection attacksinvolve maliciously crafted inputs intended to override system instructions, exfiltrate data, or cause harmful behavior. The most effective control aligned with incident management is to deploy robust input validation and sanitization(C), which includes rules and filters designed to detect and neutralize potentially malicious content before it reaches the model. AAIA's coverage of AI threats and vulnerabilities highlights the importance ofinput validation and secure prompt handlingfor generative AI systems.
Fine-tuning the model (A) is a long-term adaptation, not an immediate incident control. Scanning for code- like structure (B) or excessive special characters (D) may catch some attacks but are too narrow; many prompt injections use natural language. Comprehensiveinput validationand sanitization is the most effective and generalizable incident management response.

NEW QUESTION # 30
What should be done FIRST when an AI-powered chatbot starts giving incorrect financial advice after a backend API change?
- A. Retrain the model with historical and updated data.
- B. Push a patch to improve chatbot response speed.
- C. Suspend the chatbot and assess the impact.
- D. Add more rules to override the model's output.
Answer: C
Explanation:
When an AI system begins givingincorrect financial advice, the FIRST step is tosuspend the chatbot(D) to prevent ongoing harm. AAIA emphasizes protecting users from unsafe decisions as the top priority in AI operations.
Suspension allows the organization to:
* Stop distribution of harmful advice
* Assess impact and identify faulty API dependencies
* Prevent regulatory or customer harm
* Conduct root-cause analysis safely
Retraining (C) is corrective but must occurafterassessment. Adding rules (B) risks masking deeper issues.
Speed patches (A) are irrelevant to correctness.

NEW QUESTION # 31
When auditing an AI system, which of the following steps ensures that AI model behavior is aligned with organizational objectives?
- A. Data transformation
- B. Model training
- C. Algorithm debugging
- D. Problem framing
Answer: D
Explanation:
Problem framing (option D) is the process of clearly defining the purpose, scope, and desired outcomes of an AI system before it is built or deployed. According to the ISACA AAIA™ Study Guide, "problem framing is the critical first step that aligns model development and subsequent behaviors with the strategic and operational objectives of the organization." If the AI problem is not framed in accordance with organizational goals, even a technically successful AI model could generate outputs that do not support the organization's mission or priorities.
Algorithm debugging, data transformation, and model training are all important phases but rely on the initial problem framing to ensure their efforts are correctly directed.

NEW QUESTION # 32
An IS auditor notes the combined number of records utilized within the training, validation, and testing data sets exceeds the total number of records in the original data set. Which of the following is MOST important for the auditor to determine?
- A. Whether a sufficient number of records were utilized in the training data set
- B. Whether the validation data set utilized the same number of records as the training data sets
- C. Whether the training, validation, and testing data sets were created in the correct order
- D. Whether data leakage occurred from utilizing overlapping records in the data sets
Answer: D
Explanation:
If the combined size of the training, validation, and testing sets exceeds the original data size, it suggests that records may have been reused across sets. This can lead to data leakage, where the model has access to test or validation information during training, resulting in overly optimistic performance metrics.
"Data leakage invalidates model evaluation because it introduces unintended data overlap. Auditors must ensure that the training, validation, and test sets are strictly partitioned." Options A, C, and D refer to process order or quantity, but only B addresses the root issue of compromised model integrity due to overlapping data.
Reference: ISACA Advanced in AI Audit™ (AAIA™) Study Guide, Section: "AI Fundamentals and Technologies," Subsection: "Data Partitioning and Leakage Risks"
NEW QUESTION # 33
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 reject the data set and not analyze the data.
- C. The AI output will be biased toward the first 3,000 tokens.
- D. The AI will prioritize high-value entries.
Answer: C
Explanation:
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.

NEW QUESTION # 34
Which of the following is the BEST use of AI to audit relationships for conflicts of interest or collusion?
- A. Graph analytics
- B. Correlation matrix
- C. Monte Carlo simulation
- D. Time series analysis
Answer: A
Explanation:
Graph analytics is specifically designed to analyze complex relationships among people, entities, transactions, and systems. According to AAIA audit methodologies, graph analytics helps identify hidden or non-obvious relationships indicative of:
* Collusion
* Fraud rings
* Undisclosed conflicts of interest
* Influence networks
* Hidden ownership structures
Correlation matrices (A) only measure linear relationships. Time series (B) identifies patterns over time, not relationships. Monte Carlo simulation (D) models uncertainty but does not uncover relational structures.
Graph analytics is the strongest AI-enabled method for mapping and auditing relational risks.

An organization's system development process has been enhanced with AI. Which of the following features presents the GREATEST risk?
- A. The AI personalizes applications for the user.
- B. All codes are generated by AI without human oversight.
- C. Non-technical users are validating AI results.
- D. The AI allocates resources for new system development projects.
Answer: B
Explanation:
Allowing AI to autonomously generate code without human review introduces significant risks, including security vulnerabilities, logic errors, and noncompliance with organizational development standards. The AAIA™ Study Guide strongly advocates for human-in-the-loop oversight, particularly in automated development contexts.
"AI-assisted development must include manual code reviews to ensure functionality, compliance, and security. Autonomous code generation without validation increases the risk of introducing undetected flaws." While A, B, and C involve operational risks or inefficiencies, only D constitutes a direct breach of secure development life cycle principles.

NEW QUESTION # 36
An organization shares an AI model with external partners. One partner reports that sensitive data has been inadvertently exposed through the model's outputs. Which of the following is the IS auditor's BEST recommendation?
- A. Disable the shared model and notify partners of the potential breach.
- B. Limit the model's outputs to anonymized results while investigating further.
- C. Retrain the model immediately and implement privacy-preserving techniques.
- D. Audit the data pipelines of all partners to identify the source of the leak.
Answer: A
Explanation:
In the case of a potential data exposure through AI model outputs, the first and most responsible action from an auditing and risk standpoint is to halt further risk propagation. According to the AAIA™ Study Guide, immediate containment is vital, especially when regulatory and reputational risks are high.
"Upon detection of a data breach risk, AI models should be immediately disabled from public or partner use, and all relevant parties should be notified as part of a responsible disclosure and containment strategy." While options A and D are longer-term remediation steps and B is investigative, none of them provide the urgent containment that is best practice in such a breach context.

NEW QUESTION # 37
The PRIMARY purpose of maintaining an audit trail in AI systems is to:
- A. Facilitate transparency and traceability of decisions.
- B. Ensure compliance with regulatory standards for AI.
- C. Analyze model accuracy and fairness.
- D. Measure computational efficiency.
Answer: A
Explanation:
Audit trails in AI systems serve to document the inputs, processes, and outputs of AI decisions, allowing stakeholders and auditors to trace how decisions were made. The AAIA™ Study Guide identifies transparency and traceability as the core functions of an AI audit trail.
"Maintaining audit logs is critical to explainability and accountability. It ensures that decisions made by AI systems can be reconstructed and assessed for accuracy, ethics, and legality." Although compliance (D) is an outcome and fairness (B) a goal, only A captures the foundational purpose of audit trails in AI systems.

NEW QUESTION # 39
Which of the following is an IS auditor MOST likely to use in order to ensure an AI model has the ability to make correct predictions?
- A. Group analysis
- B. Confusion matrix
- C. Latency testing
- D. Adversarial testing
Answer: B
Explanation:
The confusion matrix is a key performance evaluation tool in machine learning and AI auditing. According to the AAIA™ Study Guide, a confusion matrix presents detailed information about actual versus predicted classifications, allowing auditors to assess accuracy, precision, recall, and F1 scores.
"A confusion matrix reveals not just how often predictions are correct, but also the types of errors being made-false positives and false negatives-thereby providing a clear view of the model's predictive reliability." Adversarial testing evaluates robustness, group analysis identifies bias across subgroups, and latency testing examines performance speed-not predictive accuracy. Thus, D is the most relevant for ensuring correct predictions.
