- Simplified Onboarding
- All of these
Answer: All of these
CBDC inclusion features: offline mode for connectivity-challenged areas, low transaction costs vs traditional banking, simplified KYC for basic accounts. Critical for expanding financial access.
Which technology enables confidential CBDC transactions while allowing regulatory audit?
- Zero-Knowledge Proofs
- Homomorphic Encryption
- Secure Multi-Party Computation
- All of these
Answer: All of these
Privacy-enhancing technologies: ZK-proofs verify without revealing data; homomorphic encryption enables computation on ciphertext; SMPC allows joint processing. Balance privacy with regulatory oversight.
Which regulatory approach treats crypto assets based on their economic function rather than underlying technology?
- Technology-Neutral Regulation
- Substance-Over-Form Principle
- Risk-Based Supervision
- All of these
Answer: All of these
Modern crypto regulation focuses on economic substance: payment tokens, security tokens, utility tokens regulated by function. Avoids technology lock-in and adapts to innovation. Critical for policy design.
Which Indian provision requires crypto exchanges to maintain records for 5 years?
- PMLA Rules
- IT Act
- SEBI Guidelines
- RBI Directions
Answer: PMLA Rules
PMLA rules require VASPs to maintain KYC records, transaction logs, and audit trails for 5 years. Enables regulatory oversight, investigation, and compliance verification. Critical for operational requirements.
Which CBDC feature enables automatic compliance with transaction limits and reporting?
- Programmable Rules
- Smart Contracts
- Both A and B
- Neither
Answer: Both A and B
Programmable CBDC with embedded rules can enforce AML limits, reporting thresholds, and policy conditions automatically. Enhances compliance efficiency while requiring careful privacy design.
Which standard verifies that carbon offset projects deliver additional emission reductions?
- Additionality Assessment
- Baseline Methodology
- Third-party Verification
- All of these
Answer: All of these
Carbon credit integrity requires: additionality proof (beyond business-as-usual), robust baseline setting, independent verification. Standards: Verra, Gold Standard ensure methodological rigor for credible offsets.
Which practice extends hardware lifespan to reduce electronic waste?
- Modular Design
- Repairability Standards
- Software Optimization
- All of these
Answer: All of these
Sustainable hardware: modular design enables component upgrades; repairability standards ensure spare parts availability; software optimization reduces need for hardware replacement. Critical for circular economy.
Which technology enables real-time monitoring of methane emissions from oil/gas infrastructure?
- Satellite Remote Sensing
- Drone-based Sensors
- Ground-based Detectors
- All of these
Answer: All of these
Methane monitoring combines: satellite (GHGSat, Sentinel), drones for targeted surveys, ground sensors for continuous monitoring. Critical for leak detection, regulatory compliance, and climate mitigation.
Which technology mitigates signal degradation due to atmospheric conditions in satellite links?
- Adaptive Coding and Modulation
- Diversity Reception
- Power Control
- All of these
Answer: All of these
Satellite link adaptation: ACM adjusts modulation/coding based on channel quality; diversity uses multiple paths; power control compensates fading. Critical for reliable broadband service in variable weather.
Which CBDC design choice impacts monetary policy transmission?
- Remuneration Rate
- Holding Limits
- Interoperability
- All of these
Answer: All of these
CBDC design affects monetary policy: remuneration influences deposit rates, holding limits prevent bank disintermediation, interoperability affects payment system dynamics. Critical for central bank digital currency planning.
Which privacy technique enables selective disclosure of transaction details in CBDC?
- Zero-Knowledge Proofs
- Ring Signatures
- Confidential Transactions
- All of these
Answer: All of these
Privacy-preserving CBDC: ZK-proofs verify without revealing data; ring signatures obscure sender; confidential transactions hide amounts. Balance user privacy with regulatory auditability requirements.
Which CBDC benefit enables faster cross-border payments compared to correspondent banking?
- Direct Central Bank Settlement

- Reduced Intermediaries
- All of these
Answer: All of these
CBDC cross-border: direct central bank-to-central bank settlement, operates 24/7, reduces correspondent layers. Critical for trade finance efficiency, remittance cost reduction, and financial inclusion.
Which framework classifies crypto assets based on economic function rather than technology?
- Technology-Neutral Approach
- Substance-Over-Form
- Risk-Based Regulation
- All of these
Answer: All of these
Modern crypto regulation focuses on economic substance: payment tokens, security tokens, utility tokens regulated by function. Avoids technology lock-in and adapts to innovation. Critical for policy design questions.
