Small satellite launch vehicles like SSLV enable cost-effective access to space for dedicated missions.
- True
- False
Answer: True
SSLV (ISRO) and similar small launchers provide dedicated launches for mini/micro satellites, reducing cost and schedule uncertainty vs rideshare. Critical for responsive space access and innovation.
Which CBDC design enables interoperability with existing payment systems?
- API-Based Integration
- Common Standards
- Both A and B
- Neither
Answer: Both A and B
CBDC interoperability: APIs enable integration with UPI, cards, wallets; common standards (ISO 20022) ensure seamless data exchange. Critical for user adoption and payment ecosystem evolution.
The international standard for crypto asset service provider registration is developed by ________.
- AI-based / Machine Learning
- Parquet
- FATF / Financial Action Task Force
- chmod
Answer: FATF / Financial Action Task Force
FATF sets global AML/CFT standards for VASPs: registration, KYC, Travel Rule compliance. Countries implement through domestic laws. Critical for cross-border crypto regulatory alignment.
Which CBDC benefit enables financial inclusion for unbanked populations?
- Offline Capability
- Low-Cost Transactions
- 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.
The CBDC feature that allows transactions to be reversed under specific conditions is called ________ Capability.
- Testable
- Serverless
- Digital India / UPI
- Reversibility / Recoverability
Answer: Reversibility / Recoverability
Controlled reversibility enables transaction reversal for fraud, error, or legal orders while preserving finality for legitimate transactions. Critical for consumer protection and regulatory compliance.
Wholesale CBDC can enable real-time gross settlement of interbank transactions.
- True
- False
Answer: True
e₹-W enables instant, final settlement between banks and financial institutions, reducing counterparty risk and liquidity needs. Critical for payment system modernization and financial stability.
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.
The CBDC architecture that combines centralized control with distributed validation is called ________ Ledger.
- Permissioned Distributed / Hybrid
- Rectifier
- Uncertainty / Observer
- Smart / Responsive
Answer: Permissioned Distributed / Hybrid
Hybrid ledger: central bank controls issuance/monetary policy, distributed nodes validate transactions. Balances sovereignty, resilience, and performance for national digital currency systems.
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.
Liquid cooling systems for data centers can achieve higher energy efficiency than air cooling.
- True
- False
Answer: True
Liquid cooling (direct-to-chip, immersion) removes heat more efficiently than air, enabling higher server density and lower PUE. Critical for high-performance computing and sustainable data center design.
