B It can be used for impersonation, fraud, and misinformation
C It is always easy to detect
D It cannot affect investigations
General MCQs PPSC

Correct Answer: B

Deepfakes pose serious security and ethical risks, as they can be used for financial fraud, spreading misinformation, and impersonating individuals.

Q1884.In AI-assisted investigations, what does 'auditability' mean?

Easy
A AI works without logs
B The AI process and decisions can be reviewed and traced
C The system automatically deletes outputs
D The model hides its reasoning
Computer Terminology PPSC

Correct Answer: B

Auditability ensures that AI-assisted decisions can be step-by-step examined, traced, and verified for transparency and legal compliance.

Q1885.Which is the best practice when using AI-generated summaries of seized documents?

Easy
A Accept them without checking
B Compare summaries with original documents to verify details
C Delete original documents to save space
D Use summaries as final evidence directly
General MCQs PPSC

Correct Answer: B

AI summaries can omit or hallucinate critical details; therefore, they must always be verified against the original evidence.

Q1886.Why should sensitive case details not be entered into public AI tools?

Easy
A AI cannot read them
B They may create data privacy, leaks, and confidentiality risks
C They improve device battery life
D They make prompts shorter
Computer Terminology PPSC

Correct Answer: B

Entering confidential or sensitive data into public AI chatbots poses a critical risk of data leakage and compromises case privacy.

Q1887.What is an adversarial prompt?

Easy
A A normal polite request
B A prompt designed to mislead, exploit, or manipulate the AI system
C A simple summarization request
D A translation task
Computer Terminology PPSC

Correct Answer: B

Adversarial prompts are specifically designed to manipulate the model's behavior, bypass safety guardrails, or force unintended outputs.

Q1888.Which LLM setting is most suitable for consistent, factual answers?

Easy
A High temperature
B Low temperature
C Random temperature
D Maximum creativity mode
General MCQs PPSC

Correct Answer: B

Lowering the temperature setting in an LLM minimizes randomness and creativity, producing more focused and consistent factual responses.

Q1889.What is the biggest danger of using generative AI to create synthetic evidence?

Easy
A It uses more RAM
B It can mislead investigations, damage truth-finding, and mislead courts
C It improves evidence accuracy
D It reduces file size
Computer Terminology PPSC

Correct Answer: B

Synthetic or fabricated evidence generated by AI can completely compromise the integrity of investigations and legal processes.

Q1890.Which method best reduces hallucination in an LLM used for official work?

Easy
A Higher temperature
B Grounding answers in verified documents or reference materials
C Asking vague questions
D Removing all context
General MCQs PPSC

Correct Answer: B

Grounding responses in verified sources or documents (such as through RAG) ensures that the AI relies on actual facts rather than training weights.

Q1891.Why is human-in-the-loop oversight important in high-stakes AI use?

Easy
A It removes all errors automatically
B It ensures human review, validation, and accountability
C It makes AI slower only
D It replaces legal procedures
Computer Terminology PPSC

Correct Answer: B

Human-in-the-loop ensures that high-stakes decisions generated or suggested by AI systems are reviewed by qualified experts to maintain accountability.

Q1892.What is a jailbreak attempt in LLM usage?

Easy
A Improving model speed
B Trying to bypass safety rules, restrictions, or policy constraints
C Updating antivirus software
D Reducing file size
Computer Security PPSC

Correct Answer: B

Jailbreaking is a malicious prompting technique used to bypass a model's safety and ethical filters to generate restricted content.

Q1893.Which risk occurs when an LLM reveals sensitive information from its training or prompt data?

Easy
A Data/privacy leakage
B Tokenization
C Image compression
D Overclocking
Computer Basics PPSC

Correct Answer: A

Data leakage occurs when an AI model exposes private training data or confidential user inputs in its responses.

Q1894.Which is the safest use of an LLM in case analysis?

Easy
A Replacing the investigator completely
B Assisting with summarization while human investigators verify results
C Creating synthetic evidence
D Ignoring chain of custody
General MCQs PPSC

Correct Answer: B

LLMs are best utilized as tools to accelerate document processing, but human review must remain the final step to guarantee accuracy.

Q1895.In an official investigation, why should LLM-generated legal references be verified?

Easy
A LLMs are always offline
B LLMs may hallucinate convincing but fake citations
C LLMs cannot read text
D LLMs only process images
General MCQs PPSC

Correct Answer: B

LLMs are prone to hallucinating citations or legal references that appear highly authentic but are completely fabricated.

Q1896.What is a prompt injection attack?

Easy
A A hardware failure
B An attempt to manipulate an AI model through malicious instructions
C A type of image filter
D A database error
Computer Terminology PPSC

Correct Answer: B

Prompt injection is an exploit targeting LLMs where untrusted inputs are used to override the system instructions and hijack model behavior.

Q1897.Which use of LLMs is helpful and ethical for students?

Easy
A Learning concepts with explanations and examples
B Cheating in exams
C Creating fake certificates
D Spreading rumors
Computer Networks PPSC

Correct Answer: A

Students can safely use LLMs as interactive study partners to clarify complex terms and explore examples ethically.

Q1898.What is the plagiarism risk in using Generative AI?

Correct Answer: A

Plagiarism risk occurs when a user passes off AI-generated output as their own work without original thought or attribution.

Q1899.Which practice helps reduce hallucinations in LLM systems?

Easy
A Asking vague questions
B Requesting sources or using retrieved grounding documents
C Increasing randomness
D Ignoring context
General MCQs PPSC

Correct Answer: B

Restricting the model's focus to verified grounding documents prevents it from making up false answers.
