Technology – MCQ – GK Questions

Q: Which encryption method uses a pair of keys (public and private) for secure communication?

Asymmetric Encryption – Asymmetric Encryption (Public-Key Cryptography) uses two mathematically related keys: public key for encryption and private key for decryption. Examples include RSA, ECC, and Diffie-Hellman. It enables secure key exchange and digital signatures, unlike symmetric encryption which uses a single shared key.

Q: Which regulatory approach treats crypto assets based on economic function rather than technology?

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.

Q: Which Indian authority monitors crypto transactions for suspicious activity reporting?

FIU-IND – Financial Intelligence Unit-India (FIU-IND) receives, analyzes, and disseminates financial intelligence including crypto transactions. VASPs must register and report suspicious activities under PMLA.

Q: Which mechanism ensures carbon credits represent real emission reductions?

All of these – Carbon credit integrity: additionality proves reductions beyond business-as-usual; robust baselines define counterfactual; independent verification ensures accuracy. Critical for market credibility.

Q: Which practice reduces cloud computing emissions by scheduling workloads during renewable energy peaks?

Both A and B – Carbon-aware computing: schedule batch jobs when grid renewable fraction is highest, use geographic load balancing to low-carbon regions. Critical for sustainable cloud operations.

Q: Which technology enables real-time monitoring of urban air quality for pollution control?

All of these – Urban air quality monitoring: IoT sensors for hyperlocal data, satellites for regional patterns, AI for source attribution and forecasting. Critical for public health and environmental policy.

Q: Which technology enables high-capacity satellite backhaul for 5G networks?

Both A and B – High-Throughput Satellites (HTS) with Ka-band provide 100+ Gbps capacity for 5G backhaul in remote areas. Critical for bridging digital divide and supporting mobile network expansion.

Q: Which CBDC benefit enables programmable subsidies with usage restrictions?

Both A and B – Programmable CBDC enables subsidies usable only for specific goods/services (food, education), preventing misuse while ensuring benefits reach intended purposes. Critical for social welfare efficiency.

Q: Which CBDC design enables offline transactions with fraud prevention?

Both A and B – Offline CBDC security: secure hardware (SE/TEE) prevents tampering; transaction limits minimize loss exposure; delayed synchronization enables fraud detection. Critical for inclusive yet secure design.

Q: Which regulatory principle ensures crypto rules are proportionate to risks posed?

All of these – Effective crypto regulation: proportionate to actual risks (not one-size-fits-all), technology-neutral (focus on function), risk-based (higher scrutiny for higher-risk activities). Critical for balanced policy design.
