- 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

- 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
- 24/7 Operation
- 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.
Which Indian provision imposes 1% TDS on cryptocurrency transactions?
- Section 194S
- Section 115BBH
- Section 43A
- Section 66
Answer: Section 194S
Section 194S (Income Tax Act) imposes 1% TDS on transfer of virtual digital assets above threshold. Aims to track transactions and ensure tax compliance. Critical for crypto tax reporting obligations.
