A security approach that assumes no user or device is trusted by default, even inside the network, is called ________ Trust.
Answer: Zero
Zero Trust is a cybersecurity framework that requires strict identity verification for every person and device accessing resources on a private network, regardless of location. It follows 'never trust, always verify' principle, using micro-segmentation, least-privilege access, and continuous monitoring.
The technology that creates fully immersive digital environments replacing the real world is called ________ Reality.
Answer: Virtual
Virtual Reality (VR) creates simulated 3D environments that users can interact with using headsets and controllers. Unlike AR which augments reality, VR completely replaces the physical world. Applications include gaming, training simulations, virtual tours, and therapeutic uses.
The CBDC pilot testing cross-border payments with other central banks is called ________ Pilot.
Answer: mBridge / Multi-CBDC
Multi-CBDC platforms (mBridge, Project Dunbar) test cross-border settlements using interoperable digital currencies. Aims to reduce cost, time, and intermediaries in international payments.
The technology that uses AI to optimize electric vehicle charging based on grid conditions is called ________ Charging.
Answer: Smart / V2G
Smart charging: AI optimizes EV charging timing based on grid load, renewable availability, electricity prices. V2G enables bidirectional flow for grid services. Critical for sustainable mobility integration.
The process of producing rocket fuel from lunar water ice is called ________ Production.
Answer: Propellant / ISRU
In-situ propellant production: electrolyze lunar water ice into hydrogen/oxygen for rocket fuel. Enables lunar refueling depot for deep space missions, reducing Earth launch mass requirements.
The international body that sets standards for crypto asset service provider supervision is ________.
Answer: FATF / Financial Action Task Force
FATF provides global AML/CFT standards for VASPs: registration, risk assessment, Travel Rule implementation. Countries align domestic regulations for cross-border consistency.
The CBDC feature that enables transaction privacy for small-value payments is called ________ Threshold.
Answer: Privacy / Anonymity
Privacy thresholds allow small CBDC transactions with minimal identity disclosure, balancing inclusion with AML requirements. Larger transactions require enhanced verification. Critical for user adoption.
