- C2M2
- ISO 27001
- COBIT
Answer: C2M2
C2M2 (Cybersecurity Capability Maturity Model) by US DOE assesses/improves cybersecurity in energy, water, and other critical sectors. Adopted globally for infrastructure resilience. Critical for critical infrastructure protection questions.
Digital trade agreements increasingly address data flows, privacy, and digital taxation.
- True
- False
Answer: True
Modern trade agreements (DEPA, RCEP digital chapters) cover: cross-border data flows, data localization, e-commerce, and digital services taxation. Critical for understanding global digital economy governance.
Which skill is most critical for data scientists to extract insights from unstructured data?
- SQL
- Machine Learning
- Data Visualization
- All of these
Answer: All of these

The architectural style where components communicate via lightweight HTTP APIs is called ________ Architecture.
Answer: Microservices / RESTful
Microservices decompose applications into independent services communicating via REST/HTTP APIs. Enables independent deployment, scaling, and technology diversity. Critical for modern cloud-native development questions.
Which database feature automatically distributes data across multiple nodes for scalability?
- Indexing
- Sharding
- Replication
- Caching
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. Trade-offs: cross-shard queries complexity.
5G network slicing enables creation of virtual networks optimized for specific use cases on shared infrastructure.
- True
- False
Answer: True
Network slicing partitions 5G infrastructure into logical networks with customized QoS: low-latency for autonomous vehicles, high-bandwidth for video, massive IoT for sensors. Critical for 5G monetization and industry applications.
Which initiative aims to establish global standards for trustworthy AI development?
- OECD AI Principles
- Paris Agreement
- Basel III
- WTO Rules
Answer: OECD AI Principles
OECD AI Principles (2019) provide values-based guidelines: inclusive growth, human-centered values, transparency, robustness, accountability. Adopted by 40+ countries including India. Critical for AI governance questions.
The certification that validates expertise in ethical hacking and penetration testing is called Certified ________ Hacker.
Answer: Ethical / CEH
CEH (Certified Ethical Hacker) by EC-Council validates skills in penetration testing, vulnerability assessment, and security tools. Valued for cybersecurity roles in government and enterprise. Critical for security career questions.
Which pattern isolates failures in microservices to prevent cascading outages?
- Circuit Breaker
- API Gateway
- Service Mesh
- Load Balancer
Answer: Circuit Breaker
Circuit Breaker stops requests to failing services temporarily, allowing recovery. Prevents cascading failures in distributed systems. Implemented in resilience libraries. Critical for building fault-tolerant architectures.
NewSQL databases combine SQL interface with NoSQL scalability for transactional workloads.
- True
- False
Answer: True
NewSQL (CockroachDB, TiDB) provides ACID transactions, SQL compatibility, and horizontal scaling. Bridges gap between traditional RDBMS and NoSQL. Critical for modern database architecture questions.
