The technology underlying most cryptocurrencies that enables decentralized consensus is called ________.
- Serverless
- Water Ice / Oxygen
- Blockchain
- dimensions
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.
FATF recommendations require Virtual Asset Service Providers to implement AML/CFT measures.
- True
- False
Answer: True
FATF (Financial Action Task Force) Travel Rule requires VASPs to share sender/receiver information for crypto transactions above threshold. India aligns regulations with FATF standards for anti-money laundering.
Which CBDC design enables offline transactions for financial inclusion?
- Token-based
- Account-based
- Hybrid
- All of these
Answer: Hybrid
Hybrid CBDC design combines online (account-based) and offline (token-based) capabilities. Offline mode uses secure hardware for transactions without internet. Critical for rural inclusion and disaster resilience.
The Indian tax provision that imposes 30% tax on income from virtual digital assets is Section ________ of Income Tax Act.
- 800-207
- 1,00,000
- 194S
- 115BBH
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.
Which feature distinguishes CBDC from cryptocurrencies like Bitcoin?
- Central Bank Issuance
- Legal Tender Status
- Regulatory Oversight
- All of these
Answer: All of these
CBDCs are sovereign digital currency: issued by central banks, legal tender status, regulated monetary policy. Cryptocurrencies are decentralized, volatile, and largely unregulated. Critical for understanding digital money evolution.
India's Central Bank Digital Currency (e₹) is a digital form of legal tender issued by RBI.
- True
- False
Answer: True
e₹ (e-Rupee) is RBI-issued digital token representing sovereign currency. Two types: retail (e₹-R) for public transactions via wallets, wholesale (e₹-W) for interbank settlements. Built on distributed ledger technology.
Which technology enables real-time monitoring of forest cover and deforestation using satellites?
- Remote Sensing
- GIS Mapping
- AI Analytics
- All of these
Answer: All of these
Forest monitoring combines: satellite imagery (Sentinel, Resourcesat), GIS for spatial analysis, AI for change detection. Used for REDD+ programs and climate reporting. Critical for environmental governance.
The metric that measures data center energy efficiency is called Power Usage ________.
- Latency
- Effectiveness / PUE
- Digital India / UPI
- ASVS / Application Security Verification Standard
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.
Green hydrogen produced via electrolysis using renewable electricity has zero carbon emissions.
- True
- False
Answer: True
Green hydrogen (renewable-powered electrolysis) produces only water as byproduct. Critical for decarbonizing hard-to-abate sectors: steel, cement, shipping. India's National Green Hydrogen Mission targets production leadership.
Which practice reduces data center energy consumption through efficient cooling and hardware?
- Virtualization
- Liquid Cooling
- Renewable Energy
- All of these
Answer: All of these
Green computing combines: virtualization (server consolidation), advanced cooling (liquid, free-air), renewable energy (solar, wind), and energy-efficient hardware. Critical for sustainable IT infrastructure.
The mechanism that allows countries to trade carbon credits for emission reductions is called ________ Trading.
- Water Ice / Oxygen
- Carbon / Emissions
- Identity
- Quantum
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.
Which technology captures CO2 from industrial emissions for storage or utilization?
- Carbon Capture and Storage
- Direct Air Capture
- Both A and B
- Neither
Answer: Both A and B
CCS captures CO2 from point sources (power plants); DAC extracts from ambient air. Both enable net-zero pathways. India developing CCS roadmap under National Carbon Capture Program.
Reusable launch vehicles reduce space access costs by enabling multiple flights of same hardware.
- True
- False
Answer: True
Reusable rockets (SpaceX Falcon 9, ISRO RLV-TD) recover and refurbish boosters, reducing launch costs by 30-70%. Critical for sustainable space economy and frequent satellite deployments.
The frequency band used for high-bandwidth satellite internet in Ka-band is ________ GHz.
- 115BBH
- 26.5-40
- 4.0
- 7
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.
Which ISRO mission is designed to study the Sun's corona and space weather?
- Chandrayaan-3
- Aditya-L1
- Gaganyaan
- NISAR
Answer: Aditya-L1
Aditya-L1 positioned at Sun-Earth L1 point for uninterrupted solar observation. Studies coronal heating, CMEs, solar flares critical for space weather forecasting affecting satellites and power grids.
Chandrayaan-3's successful landing near Moon's south pole enables study of water ice deposits.
- True
- False
Answer: True
Moon's south pole has permanently shadowed craters with water ice, valuable for future lunar bases (life support, rocket fuel). Chandrayaan-3's Pragyan rover analyzed soil composition. Critical for space resource questions.
