The cryptographic technique that allows verification of statements without revealing underlying data is called Zero-________ Proofs.
Answer: Knowledge
Zero-Knowledge Proofs enable proving knowledge of a secret without revealing it. Applications: privacy-preserving authentication, confidential transactions, secure voting. Critical for next-gen privacy technologies.
The practice of testing AI systems with diverse datasets to detect bias is called ________ Testing.
Answer: Bias / Fairness
Bias Testing evaluates AI performance across demographic groups to identify disparate impact. Techniques: disaggregated metrics, counterfactual fairness, adversarial debiasing. Critical for equitable AI deployment.
The pilot phase of India's retail CBDC allows transactions via ________ wallets issued by partner banks.
Answer: Digital / e₹
e₹-R pilot involves major banks issuing digital wallets for retail transactions: P2P, P2M, QR payments. Tests usability, scalability, and integration with existing payment systems before full rollout.
The global standard for crypto asset classification and regulation is developed by ________.
Answer: FATF / Financial Action Task Force
FATF provides international standards for virtual assets: definition of VASPs, Travel Rule, risk-based supervision. Countries implement through domestic laws. Critical for cross-border crypto compliance.
The technology underlying most cryptocurrencies that enables decentralized consensus is called ________.
Answer: Blockchain
Blockchain is distributed ledger using cryptographic hashing and consensus mechanisms (PoW, PoS) for tamper-resistant record-keeping. Foundation for Bitcoin, Ethereum, and many CBDC prototypes.
The Indian tax provision that imposes 30% tax on income from virtual digital assets is Section ________ of Income Tax Act.
Answer: 115BBH
Section 115BBH (introduced FY 2022-23) taxes crypto income at 30% plus cess, with 1% TDS on transactions. No loss offset allowed. Critical for crypto taxation compliance questions.
The metric that measures data center energy efficiency is called Power Usage ________.
Answer: Effectiveness / PUE
PUE = Total Facility Energy / IT Equipment Energy. Ideal PUE is 1.0; modern data centers achieve 1.1-1.3. Critical for measuring and improving data center sustainability.
The mechanism that allows countries to trade carbon credits for emission reductions is called ________ Trading.
Answer: Carbon / Emissions
Carbon trading (cap-and-trade) sets emission limits and allows trading of allowances. India exploring carbon markets under Climate Change Act. Critical for climate policy and finance questions.
The frequency band used for high-bandwidth satellite internet in Ka-band is ________ GHz.
Answer: 26.5-40
Ka-band (26.5-40 GHz) offers high bandwidth for satellite broadband but susceptible to rain attenuation. Requires adaptive coding and ground station diversity. Critical for satellite communication planning.
