Answer: Quantum Key Distribution
QKD uses quantum properties (no-cloning, measurement disturbance) to detect interception during key exchange. Provides information-theoretic security for encryption keys. Deployed in limited networks globally.
The document that summarizes an AI system's capabilities, limitations, and ethical considerations is called a ________ Card.
- Combined Gas and Gas (COGAG)
- Digital Personal Data Protection
- Fourth
- Model
Answer: Model
Model Cards provide standardized documentation: intended use, training data characteristics, performance metrics across groups, ethical considerations. Enable informed deployment decisions and accountability.
Which practice ensures AI training data represents diverse populations to avoid bias?
- Data Augmentation
- Representative Sampling
- Bias Auditing
- All of these
Answer: All of these
Fair AI requires: representative datasets covering demographics, augmentation to address underrepresentation, and continuous bias auditing. Critical for equitable AI in hiring, lending, healthcare.
Explainable AI (XAI) techniques help non-technical users understand model predictions.
- True
- False
Answer: True
XAI methods (LIME, SHAP, attention visualization) provide interpretable explanations for AI decisions. Critical for trust, debugging, regulatory compliance, and user acceptance in high-stakes applications.
Which Indian law provides legal recognition to electronic records and digital signatures?
- DPDP Act 2023
- IT Act 2000
- Cyber Security Strategy
- Data Governance Policy
Answer: IT Act 2000
Information Technology Act 2000 (amended 2008) provides legal framework for e-commerce, electronic records, digital signatures, and cybercrime penalties. Foundation for digital transaction legality in India.
The consensus mechanism used by Ethereum after The Merge is called Proof of ________.
- Interdisciplinary Cyber Physical Systems / NM-ICPS
- Stake / PoS
- Ransomware
- Closed-loop / Feedback
Answer: Stake / PoS
Ethereum transitioned from Proof of Work to Proof of Stake (The Merge, 2022), reducing energy consumption by ~99.95%. Validators stake ETH to propose/attest blocks. Critical for understanding crypto sustainability.
India's crypto tax framework allows loss offsetting against other capital gains.
- True
- False
Answer: False
Section 115BBH taxes crypto income at 30% with no provision for loss offsetting against other income or capital gains. 1% TDS applies on transactions. Critical for crypto tax compliance planning.
Which CBDC design choice impacts user privacy versus regulatory compliance?
- Token vs Account-based
- Centralized vs Distributed Ledger
- Online vs Offline Capability
- All of these
Answer: All of these
CBDC architecture involves trade-offs: token-based offers more privacy but harder AML; distributed ledgers enhance resilience but complex governance; offline mode improves inclusion but security challenges.
The technology that uses AI to optimize energy consumption in buildings is called ________ Management System.
- Building Energy / BEMS
- Reinforcement
- Green
- Columnar
Answer: Building Energy / BEMS
BEMS uses IoT sensors, AI analytics, and automation to optimize HVAC, lighting, and equipment operation. Reduces energy waste by 20-40% while maintaining comfort. Critical for green building certifications.
Which practice reduces electronic waste by extending device lifespan through repair and upgrades?
- Planned Obsolescence
- Right to Repair
- Fast Fashion
- Single-Use Design
Answer: Right to Repair
Right to Repair legislation mandates manufacturers provide parts, tools, documentation for device repair. Reduces e-waste, saves consumer costs, and promotes circular economy. India developing e-waste rules with repair provisions.
Article 6 of Paris Agreement enables international cooperation on carbon markets and emission trading.
- True
- False
Answer: True
Article 6 establishes frameworks for internationally transferred mitigation outcomes (ITMOs) and sustainable development mechanism. Enables countries to collaborate on cost-effective emission reductions.
