NEW QUESTION # 18
An IS auditor notes that an AI model achieved significantly better results on training data than on test data.
Which of the following problems with the model has the IS auditor identified?
- A. Generalization
- B. Overfitting
- C. Bias
- D. Underfitting
Answer: B
Explanation:
Overfitting occurs when a model performs very well on training data but poorly on unseen data, indicating that the model has learned patterns specific to the training set rather than generalizing effectively. The AAIA™ Study Guide identifies overfitting as a common problem that impacts model reliability.
"Overfitting limits the model's applicability to real-world scenarios. It reflects excessive tailoring to the training data and poor performance on new, diverse inputs." Underfitting (A) would result in poor performance on both training and test data. Generalization (C) is the desired state, and bias (D) is a separate issue. Therefore, B is correct.

NEW QUESTION # 19
A bank uses a video-based know your customer (KYC) verification process. Cybercriminals exploit this process by using deepfake technology to impersonate bank customers. Which of the following countermeasures is the BEST way for the bank to mitigate this risk?
- A. Encrypting all customer data and communication
- B. Discontinuing the use of the video-based verification process
- C. Requesting additional identity and address documents for verification
- D. Leveraging AI-based liveness detection during video verification
Answer: D
Explanation:
Liveness detection is the most effective countermeasure against deepfakes in video-based verification. AI- based liveness detection analyzes facial movement, micro-expressions, and other biometric cues to differentiate real humans from manipulated video content.
"To protect against identity spoofing and deepfake exploitation, biometric systems must incorporate liveness detection protocols capable of detecting synthetic imagery or falsified video data." Encryption (C) protects data at rest and in transit but does not prevent impersonation. Discontinuation (D) may not be necessary if effective countermeasures like B are in place.

NEW QUESTION # 20
An organization uses an AI-powered tool to detect and respond to cybersecurity threats in real time. An IS auditor finds that the tool produces excessive false positives, increasing the workload of the security team.
Which of the following techniques should the auditor recommend to BEST evaluate the tool's effectiveness in managing this issue?
- A. Use a log analysis tool to examine the types and frequency of alerts generated.
- B. Deploy a machine learning (ML) validation tool to increase the model's accuracy and performance.
- C. Conduct penetration testing to assess the system's ability to detect genuine threats.
- D. Implement a benchmarking tool to compare the system's alerting capability with industry standards.
Answer: B
Explanation:
The AAIA™ Study Guide recommends using validation tools to fine-tune and evaluate ML models, particularly when high false positives undermine operational efficiency. ML validation can identify threshold adjustments, retraining needs, or feature misweighting contributing to excessive alerting.
"Model validation enables organizations to quantify performance, reduce false alarms, and recalibrate AI behavior to align with operational needs and threat landscapes." While logs (A) and benchmarks (B) help with diagnosis, they don't improve the model. Penetration testing (C) evaluates detection, not alert noise. D is the most effective solution.
Reference: ISACA Advanced in AI Audit™ (AAIA™) Study Guide, Section: "AI Operations and Performance," Subsection: "Model Tuning and False Positive Mitigation"
NEW QUESTION # 21
An IS auditor is reviewing change documentation of an AI model. Which of the following would pose the GREATEST risk?
- A. The seed used for testing is not documented.
- B. Test results are not in a standardized format.
- C. There is a low number of test scenarios.
- D. Management has not tested the model.
Answer: C
Explanation:
Alow number of test scenarios(C) indicates insufficient testing coverage, creating a high likelihood that errors, biases, or edge-case failures remain undetected. AI systems requirebroad, diverse scenario testing, including fairness, robustness, and stress testing. AAIA highlights comprehensive testing as essential to AI reliability and risk mitigation.
Lack of standardized test formats (B) is inefficient but less severe. Missing seed documentation (D) affects reproducibility but not completeness. Lack of management testing (A) matters, but insufficient test scenarios pose thelargest direct riskto model safety and performance.

NEW QUESTION # 22
Which of the following is the MOST important reason to perform regular ethical reviews of AI systems?
- A. To ensure the systems align with the preservation of individual rights
- B. To improve the accuracy and performance of the systems
- C. To identify and mitigate potential data drift within models
- D. To align AI system development with organizational values and principles
Answer: A
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.

Which of the following is the PRIMARY objective of performing adversarial testing on AI models?
- A. Validating AI incident response plans
- B. Fostering security awareness
- C. Determining key risk indicators (KRIs)
- D. Identifying control gaps
Answer: D
Explanation:
Adversarial testinginvolves simulating real-world attacks or malicious inputs against AI models (e.g., adversarial examples, poisoning, evasion) to identify how the system behaves under intentional misuse or hostile conditions. Theprimary objectiveis to discoverweaknesses and control gaps(D) in the model and its surrounding processes-such as inadequate input validation, insufficient monitoring, or missing safeguards against adversarial inputs.
While results from adversarial testing may inform incident response planning (A), KRI definition (B), or security awareness (C), those are secondary benefits. AAIA's coverage of AI threats and vulnerabilities emphasizes adversarial testing as acontrol validation and gap-identification mechanism, directly addressing AI-specific risk exposure.

Which use case for an AI model to be used by a food delivery service would pose ethical risk to the organization?
- A. Using customer service metrics for service speed and food quality to predict customer retention and forecast revenue
- B. Comparing total food preparation and delivery time to an industry benchmark to set key performance and risk indicators for individual restaurants
- C. Correlating time, cost, delivery distance, and customer satisfaction metrics to issue coupons to customers receiving substandard service
- D. Basing driver retention and termination decisions on the number of delivered orders per total hours worked as compared to an industry benchmark
Answer: D
Explanation:
Using AI to make employment decisions such as driver termination or retention introduces significant ethical risks. If based solely on performance metrics without context or human review, such systems can lead to unfair treatment or discrimination-violating principles of transparency and due process.
"Automating workforce decisions must be approached cautiously to prevent discriminatory outcomes. Ethical AI governance requires oversight when AI is used for employment-impacting decisions." A, C, and D involve business optimization without directly affecting individual employment rights. Therefore, B poses the greatest ethical risk.

NEW QUESTION # 26
An organization plans to share customer data collected through an AI system with third-party vendors. Which of the following BEST demonstrates compliance with data privacy principles?
- A. Ensuring vendors implement adequate technical safeguards for data protection
- B. Communicating to customers about AI data sharing practices
- C. Including a statement about AI data sharing practices in the company's privacy policy
- D. Obtaining expressed consent from customers before sharing their data
Answer: D
Explanation:
The strongest demonstration of compliance with privacy principles-especially those emphasized in AAIA, such aslawfulness, transparency, and consent-is obtainingexpressed customer consent(B) before sharing data with third parties. Consent ensures that data processing aligns with legal and ethical requirements, reducing risks related to regulatory violations, unauthorized processing, and loss of customer trust.
Option A and C relate only to disclosure and transparency, which are necessary but insufficient. Option D concerns vendor security controls, which are important but do not address the legal basis for sharing data.
Explicit, informed consentis the highest standard of compliance for third-party data sharing.

Which of the following are the MOST appropriate stages in the AI life cycle for evaluating edge cases?
- A. Plan and design
- B. Operate and monitor
- C. Collect and process
- D. Test and verify
Answer: D
Explanation:
Evaluatingedge cases-rare but critical scenarios where AI may behave unpredictably-must be done during thetest and verifystage (D). This phase is designed to simulate extreme or unusual inputs, validate performance under stress, and ensure robustness and safety before deployment. AAIA highlights that robustness testing, including edge case evaluation, is a key testing technique for AI solutions.
While planning (A) and data collection (C) prepare inputs, they do not evaluate model behavior. Operating and monitoring (B) may detect issues later, but edge case testing must occurpre-deploymentto reduce risk.

NEW QUESTION # 30
Which of the following is the MOST important task when gathering data during the AI system development process?
- A. Training the system
- B. Isolating the system
- C. Stratifying the data
- D. Cleaning the data
Answer: D
Explanation:
Data cleaning is a foundational task in the AI development lifecycle. The AAIA™ Study Guide identifies data quality-ensuring completeness, accuracy, consistency, and correctness-as critical to building effective and unbiased AI systems. Cleaning the data involves removing duplicates, correcting errors, addressing missing values, and standardizing formats.
"Data cleaning is a prerequisite for effective training and evaluation. Poor-quality data leads to inaccurate or misleading model outputs, increasing operational and ethical risks." While training (D) is essential, it must occur only after the data has been adequately prepared. Stratification (A) supports certain modeling approaches but is secondary to data integrity. Therefore, C is the most important task at the data-gathering stage.

NEW QUESTION # 32
Which of the following should be an IS auditor's GREATEST concern when reviewing an anomaly detection process implemented for a high-risk AI system?
- A. Failure to identify anomalies that can bias training data
- B. Inadequate staff training on the use of the system
- C. Infrequent updates to anomaly detection algorithms
- D. Lack of regular quality reviews for training data
Answer: A
Explanation:
In ahigh-risk AI system, anomaly detection often serves as a frontline control to flag irregularities in input data and model behavior. TheGREATEST concernfor an IS auditor is when the processfails to identify anomalies that can bias training data(A), because undetected anomalies can fundamentally distort model learning and outputs. This can lead to systemic bias, incorrect decisions, safety risks, and regulatory breaches.
Option B (lack of regular quality reviews) is serious but is partially addressed if anomaly detection is effective. Option C (infrequent updates) may degrade detection performance over time but is less critical than outright failure to detect harmful anomalies. Option D (staff training) is important for operational effectiveness but still secondary to the technical failure to catch bias-inducing anomalies. AAIA stresses that data integrity and monitoring controlsare paramount in high-risk contexts.

NEW QUESTION # 33
Which of the following should be of GREATEST concern to an IS auditor when reviewing ethical considerations for an AI solution?
- A. The solution is hosted on a shared cloud environment.
- B. The model has not been retrained recently.
- C. The solution documentation is still in draft.
- D. The decision-making process is unexplainable.
Answer: D
Explanation:
TheGREATEST concernis when the AI system'sdecision-making process is unexplainable(A), especially for high-impact or regulated decisions. AAIA stresses that explainability is essential for accountability, fairness assessments, compliance, and public trust. If decisions cannot be explained, the organization cannot validate fairness, detect bias, or justify outcomes to regulators or affected individuals.
Cloud hosting (B) is manageable through standard controls. Retraining frequency (C) affects performance but not core ethics. Draft documentation (D) is a procedural issue, not an ethical barrier. Unexplainable decision logic is thefoundational ethical risk.

NEW QUESTION # 34
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 enables the reduction of model bias by setting the K variable to higher values.
- B. It uses multiple training and testing cycles to minimize overfitting.
- C. It facilitates performing regressions on smaller data sets.
- D. It helps minimize computational costs when evaluating complex models.
Answer: B
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.
