Which section of the IT Act 2000 deals with punishment for identity theft?
- Section 66
- Section 66C
- Section 66D
- Section 67
Answer: Section 66C
Section 66C prescribes punishment (up to 3 years imprisonment + fine) for identity theft: fraudulently using another person's electronic signature, password, or unique identification feature. Section 66D covers cheating by personation using computer resources. Important for legal awareness in banking and SSC exams.
Which data structure is most efficient for implementing a cache with LRU (Least Recently Used) eviction policy?
- Array
- Linked List
- Hash Map + Doubly Linked List
- Stack
Answer: Hash Map + Doubly Linked List
LRU cache requires O(1) access and O(1) reorder on access. Hash map provides O(1) key lookup; doubly linked list maintains usage order with O(1) move-to-front. Combined, they achieve O(1) get/put operations. Classic system design question for SSC JE and banking IT exams.
The frequency at which a crystal oscillator resonates is determined by its physical ________ and cut.
- Kubernetes
- dimensions
- OECD / UNESCO
- Indigenization / Self-Reliance
Answer: dimensions
Crystal oscillators use piezoelectric quartz crystals whose resonant frequency depends on physical dimensions (thickness, shape) and crystal cut (AT, BT, SC). Thinner crystals resonate at higher frequencies. Used for precise clock generation in microcontrollers, communication systems, and digital circuits. Temperature-compensated (TCXO) and oven-controlled (OCXO) variants improve stability.
Which 5G core network architecture enables service-based interfaces and cloud-native deployment?
- EPC
- 5GC
- IMS
- Both B and C
Answer: 5GC
5GC (5G Core) uses service-based architecture (SBA) with cloud-native principles: microservices, containerization, CI/CD. Contrasts with 4G EPC's monolithic design. Benefits: flexibility, scalability, faster feature deployment, and network slicing support. IMS (IP Multimedia Subsystem) handles voice/video services and works with both EPC and 5GC.
Which technique is used to detect and mitigate bias in AI training datasets?
- Data Augmentation
- Adversarial Debiasing
- Feature Scaling
- Cross-Validation
Answer: Adversarial Debiasing
Adversarial Debiasing uses adversarial networks to remove correlations between protected attributes (gender, caste) and model predictions while preserving task performance. Other techniques: reweighting samples, bias-aware preprocessing, fairness constraints in loss function. Critical for ethical AI in hiring, lending, and public services where bias can perpetuate inequality.
The 5G feature that allows network resources to be partitioned into multiple virtual networks for different use cases is called network ________.
- Propellant / ISRU
- Slicing
- Hybrid
- Device Posture
Answer: Slicing
Network Slicing creates multiple logical networks on shared physical 5G infrastructure, each optimized for specific requirements: ultra-reliable low latency (autonomous vehicles), massive IoT (sensors), enhanced mobile broadband (video). Enables customized QoS, security, and management per slice. Critical for monetizing 5G across industries.
Which principle of Responsible AI ensures that AI system decisions can be understood and explained to users?
- Fairness
- Accountability
- Transparency
- Privacy
Answer: Transparency
Transparency (Explainable AI/XAI) ensures AI decisions are interpretable by humans, enabling trust, debugging, and regulatory compliance. Techniques: LIME, SHAP, attention visualization. Critical in high-stakes domains: healthcare diagnosis, loan approvals, criminal justice. Balances model complexity with interpretability needs.
Which RBI initiative allows regulated entities to test innovative fintech products in a controlled environment?
- RegTech
- Suptech
- Regulatory Sandbox
- Digital Lending Guidelines
Answer: Regulatory Sandbox
RBI Regulatory Sandbox enables fintech startups and banks to test new products/services with real customers under relaxed regulations for limited period/time/scale. Reduces time-to-market, fosters innovation while managing risks. Themes include retail payments, KYC, lending, cybersecurity. Successful pilots may lead to regulatory framework updates.
Model-based imputation handles missing data by modeling relationships between variables to predict missing values, accounting for uncertainty.
- True
- False
Answer: True
Model-based imputation (MICE, Bayesian) models relationships between variables to predict missing values, accounting for uncertainty. More robust than simple methods for complex missingness patterns.
The technique that enables LLMs to generate code by learning from programming language corpora is called Code LLM/Generation.
- True
- False
Answer: True
Code LLMs enable natural language to code generation, debugging, documentation.
The technique that enables LLMs to generate multiple plausible responses and select the best is called Beam/Nucleus Sampling.
- True
- False
Answer: True
Advanced decoding: beam search explores multiple hypotheses, nucleus sampling truncates low-probability tokens. Balance diversity and coherence.
Which brain-inspired feature enables neuromorphic chips to achieve ultra-low power for always-on AI?
- Spiking Neurons
- Event-Driven Processing
- Both A and B
- Neither
Answer: Both A and B
Spiking neurons fire only when needed; event-driven processing handles only changes. Combined enable orders-of-magnitude better energy efficiency than GPUs for edge AI.
The technology that uses DNA strands for massively parallel computation is called ________ Computing.
