Q141.An investigator uses AI to analyze computer drives, recover deleted chat logs, and detect tampering. This is best categorized as?
Correct Answer: B
AI-assisted digital forensics leverages advanced machine learning to accelerate, process, and inspect digital evidence in forensic investigations.
Q142.Which AI capability would best help investigators detect deepfake videos used in financial fraud?
Correct Answer: C
Computer Vision-based deepfake detection models inspect video frames for microscopic biological, artifact, or blending anomalies to uncover synthesized/manipulated faces.
Q143.In the A* algorithm, the evaluation function is f(n) = g(n) + h(n), where h(n) is the:
Correct Answer: D
h(n) is the heuristic estimate of cost from node n to the goal.
Q144.Which deep learning architecture replaced RNNs in most modern NLP due to parallelization?
Correct Answer: A
Transformers process sequences in parallel via attention, outperforming RNNs in NLP.
Q145.Which AI approach would best identify a suspect's face across thousands of CCTV frames?
Correct Answer: C
Facial recognition combined with tracking matches identities across video frames.
Q146.An AI system trained mostly on one ethnicity misidentifies others. This is an example of:
Correct Answer: A
Skewed training data causes algorithmic bias, leading to unfair misidentification.
Q147.Which technique allows an LLM to use external knowledge at query time without retraining?
Correct Answer: A
RAG retrieves relevant external documents to ground LLM responses without retraining.
Q148.Which is the correct order of a typical machine learning pipeline?
Correct Answer: C
The standard pipeline is collect, preprocess, train, evaluate, then deploy.
Q149.An AI tool flags transactions structured just below reporting thresholds. This detects:
Correct Answer: C
Detecting sub-threshold structuring helps uncover money-laundering (smurfing).
Q150.In cyber crime investigation, AI 'link analysis' is used to:
Correct Answer: D
Link analysis maps and visualizes connections among entities in investigations.
Q151.Which AI risk involves crafting inputs to deliberately fool a model?
Correct Answer: D
Adversarial attacks use specially crafted inputs to deceive AI models.
Q152.An AI 'context window' refers to:
Correct Answer: A
The context window is the maximum amount of tokens an LLM processes in one prompt.
Q153.Which is a prime concern of the EU AI Act?
Correct Answer: A
The EU AI Act regulates AI using a risk-based classification framework.
Q154.Which AI method is best to predict the next likely location of repeat offenders?
Correct Answer: D
Predictive analytics models patterns to forecast likely crime hotspots.
Q155.In a CNN, the 'kernel/filter' is responsible for:
Correct Answer: D
Convolutional kernels slide over images to detect local features such as edges.
Q156.Which AI technique would help transcribe and translate intercepted foreign-language calls?
Correct Answer: B
ASR transcribes speech and machine translation converts it across languages.
Q157.Which AI governance principle requires that individuals can contest automated decisions?
Correct Answer: C
Governance frameworks grant rights to explanation and to contest automated decisions.
Q158.An investigator uses AI to cluster similar cybercrime cases by modus operandi.
Correct Answer: D
Grouping cases by similarity without labels is unsupervised clustering.
Q159.Which AI risk describes a model leaking private training data through its outputs?
Correct Answer: B
Models can memorize and leak sensitive training data through their outputs.
Q160.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.
