Green hydrogen can be stored and used as long-duration energy storage for renewable integration.
- True
- False
Answer: True
Green hydrogen (electrolysis using renewables) stores energy chemically for days/weeks, convertible to electricity via fuel cells or turbines. Complements batteries (short-duration) for seasonal storage. India's National Green Hydrogen Mission targets this application.
Small satellites (CubeSats) enable low-cost access to space for research and commercial applications.

Red Team exercises simulate real-world attacks to test organizational security posture.
- True
- False
Answer: True
Red Teaming conducts adversarial simulations (physical, cyber, social) to identify gaps in detection, response, and resilience. Distinct from pentesting (vulnerability-focused). Critical for mature security programs and incident readiness questions.
Extreme Ultraviolet (EUV) lithography uses 13.5nm wavelength light for patterning sub-7nm features.
- True
- False
Answer: True
EUV lithography (ASML) enables single-patterning of sub-7nm features vs multi-patterning with DUV. Challenges: light source power, mask defects, resist sensitivity. Critical technology for leading-edge chips; India monitors for future capability development.
Metamaterials can exhibit properties not found in nature, like negative refractive index.
- True
- False
Answer: True
Metamaterials are engineered structures with sub-wavelength features enabling exotic properties: negative refraction, invisibility cloaking, superlenses. Applications: antennas, sensors, imaging. India researches at IITs, DRDO. Critical for advanced materials and photonics questions.
Vehicle-to-Grid (V2G) technology allows electric vehicles to supply power back to the electrical grid.
- True
- False
Answer: True
V2G enables bidirectional power flow: EVs charge during low demand, discharge during peak, providing grid services (frequency regulation, backup). Requires smart chargers, communication protocols, and regulatory frameworks. Critical for smart grid and energy transition questions.
In-orbit servicing can extend satellite lifespan by refueling or repairing components in space.
- True
- False
Answer: True
In-orbit servicing (robotic arms, refueling, upgrades) extends satellite life, reduces space debris, and enables new business models. ISRO's SPADEX tested docking; global companies (Northrop, Astroscale) develop servicing tech. Critical for space sustainability and economy questions.
Social engineering attacks manipulate human psychology rather than exploiting technical vulnerabilities.
- True
- False
Answer: True
Social engineering (phishing, pretexting, baiting) exploits human trust, curiosity, or fear to gain access or information. Often more effective than technical exploits. Defense: security awareness training, verification protocols, and least-privilege access. Critical for holistic cybersecurity understanding.
Chiplet architecture enables modular design by combining multiple smaller dies in a single package.
- True
