Answer: Virtual
Virtual Reality creates simulated 3D environments that users can interact with using headsets and controllers.
Answer: DigiLocker
DigiLocker enables citizens to store/share government-issued documents digitally. Documents have legal validity under IT Act.
Answer: Forecasting
Time series forecasting models temporal patterns for demand prediction, anomaly detection, capacity planning.
Answer: Both A and B
Time series visualization: line charts show trends clearly, area charts emphasize volume. Both effective for temporal data analysis.
Answer: Data Minimization
Data minimization limits collection to what's necessary for specified purpose. Reduces privacy risks, storage costs, breach impact.
Answer: Transparency
Transparency (Explainable AI/XAI) ensures AI decisions can be interpreted by humans. Critical for trust, debugging, regulatory compliance.
Answer: Event-Driven Architecture
Event-driven architecture uses message brokers for asynchronous, decoupled service communication. Enables scalability, resilience, real-time processing.
Answer: True
India's rapid 5G deployment driven by competitive telecom operators, government policy support, indigenous technology development. Critical for digital infrastructure questions.
Answer: Smart Contracts
Smart contracts are self-executing programs stored on blockchain that automatically enforce terms when conditions are satisfied. Used in DeFi, supply chain, insurance.
Answer: Supply Chain Traceability
Blockchain records each transaction/transfer in immutable ledger, enabling end-to-end visibility of product journey. Used for food safety, luxury goods authentication.
Answer: True
Blockchain's immutability, transparency, decentralization make it suitable for land records management. Pilot projects in Andhra Pradesh, Telangana, Maharashtra use blockchain.
Answer: e₹ / Digital Rupee
e₹ (e-Rupee) is RBI-issued digital token representing sovereign currency. Two types: retail (e₹-R) for public transactions, wholesale (e₹-W) for interbank settlements.

Answer: PMP / PRINCE2
PMP (PMI) covers traditional project management; PRINCE2 is process-based; Agile/Scrum certifications focus on iterative delivery. All valued for tech project leadership.
Answer: Chaos Engineering
Chaos Engineering (Netflix Chaos Monkey) proactively tests system resilience by injecting failures in controlled experiments. Builds confidence in fault tolerance.
Answer: True
GitOps (ArgoCD, Flux) declaratively defines desired state in Git; operators sync cluster state. Benefits: audit trail, rollback via git revert, peer review via PRs.
Answer: Code
IaC (Terraform, Ansible, CloudFormation) defines infrastructure in declarative code, enabling version control, peer review, automated testing, consistent deployments.
Answer: Both A and B
Adapter/ACL patterns wrap external APIs, translating between internal models and external interfaces. Critical for maintainable integrations and testing.
Answer: Sharding
Sharding partitions data horizontally across nodes based on key ranges or hashes, enabling horizontal scaling. Critical for handling large datasets in distributed databases.
