Answer: Stream Processing
Stream Processing (Apache Kafka, Flink, Spark Streaming) processes data in real-time as it arrives, enabling instant insights for fraud detection, IoT monitoring, and live dashboards. Batch processing handles historical data; ETL transforms data for storage; data warehousing supports analytical queries. Critical for modern data architecture questions.
Which cybersecurity framework implements 'never trust, always verify' principle for all access requests?
- Defense in Depth
- Zero Trust Architecture
- Perimeter Security
- Role-Based Access Control
Answer: Zero Trust Architecture
Zero Trust Architecture assumes no implicit trust based on network location. Every access request is authenticated, authorized, and encrypted regardless of origin. Implements micro-segmentation, least-privilege access, and continuous monitoring. Critical for modern enterprise security and frequently tested in banking/UPSC exams.
Which emerging technology combines quantum sensing with AI for ultra-precise navigation without GPS?
