Q2061.Which technique enables an LLM to perform step-by-step reasoning?
Correct Answer: B
Chain-of-Thought prompting elicits intermediate reasoning steps from LLMs.
Q2062.Which AI application can automatically extract entities (names, CNICs, accounts) from seized documents?
Correct Answer: D
NER extracts structured entities like names and IDs from unstructured text.
Q2063.Which is a key property of blockchain that aids AI-driven forensic analysis of crypto crimes?
Correct Answer: B
Blockchain's immutable, transparent ledger lets AI trace crypto transaction flows.
Q2064.Which AI subfield enables robots to plan movement while avoiding obstacles?
Correct Answer: A
Motion/path planning computes collision-free routes for robots.
Q2065.Which concept measures a model's error from overly simple assumptions?
Correct Answer: B
High bias stems from oversimplified models that underfit the data.
Q2066.Which concept measures error from sensitivity to small data fluctuations?
Correct Answer: D
High variance means the model is too sensitive to training data fluctuations (overfits).
Q2067.Which technique would best summarize thousands of seized emails for investigators?
Correct Answer: B
Abstractive summarization condenses large text volumes into concise summaries.
Q2068.Which is an example of multimodal AI?
Correct Answer: D
Multimodal AI processes and integrates multiple data types (text, image, audio).
Q2069.Which AI governance issue arises when no one can explain a model's decision?
Correct Answer: C
The black-box problem is the difficulty of interpreting complex model decisions.
Q2070.Which method is used to detect anomalies without labeled fraud examples?
Correct Answer: D
Isolation Forests and autoencoders detect anomalies in unlabeled data.
Q2071.Which AI capability lets investigators search images by content rather than filename?
Correct Answer: D
Content-based image retrieval searches images by visual features, not metadata.
Q2072.Which AI ethics term refers to AI used to manipulate public opinion at scale?
Correct Answer: B
AI can mass-produce disinformation, a major governance and ethics concern.
Q2073.Which technique improves LLM factual reliability by grounding answers in a document store?
Correct Answer: A
RAG grounds responses in retrieved documents, improving factual accuracy.
Q2074.What is a 'vector database' primarily used for in modern AI systems?
Correct Answer: D
Vector databases store embeddings and enable fast similarity search (e.g., for RAG).
Q2075.Which AI approach helps prioritize alerts in a SOC by likely severity?
Correct Answer: C
ML classifies and prioritizes security alerts to reduce analyst overload.
Q2076.Which is a correct description of 'precision-recall tradeoff'?
Correct Answer: C
Adjusting the decision threshold typically trades precision against recall.
Q2077.Which AI concept allows the same model to handle many tasks via instructions?
Correct Answer: C
Instruction-tuned foundation models generalize across tasks from natural-language prompts.
Q2078.In forensic audio analysis, AI can be used to:
Correct Answer: B
AI performs speaker identification and noise reduction in forensic audio.
Q2079.Which is a major limitation of facial recognition in real-world policing?
Correct Answer: A
Facial recognition can produce biased false matches, raising accuracy and fairness concerns.
Q2080.Which method evaluates a model on multiple data splits to reduce variance in estimates?
Correct Answer: A
k-fold cross-validation averages performance over k splits for reliable estimates.
