The Indian policy for promoting research and development in emerging technologies is called National Mission on ________.
Answer: Interdisciplinary Cyber Physical Systems / NM-ICPS
NM-ICPS (DST) funds R&D in AI, IoT, robotics, quantum technologies. Aims to build indigenous capabilities and innovation ecosystem. Critical for strategic technology questions.
Which technique handles missing data by modeling the missingness mechanism?
- Mean Imputation
- Multiple Imputation
- Model-Based Imputation
- All of these
Answer: Model-Based Imputation
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.
Hyperparameter tuning optimizes model performance by searching parameter combinations.
- True
- False
Answer: True
Hyperparameter tuning: grid search, random search, Bayesian optimization. Critical for maximizing model performance but requires careful validation to avoid overfitting.
Which visualization shows the distribution of a variable across categories?
- Box Plot
- Violin Plot
- Both A and B
- Neither
Answer: Both A and B
Box plots show median, quartiles, outliers; violin plots add density estimation. Both effective for comparing distributions across categories. Critical for exploratory data analysis.
The technique that splits data into training and testing sets while preserving class distribution is called ________ Sampling.
Answer: Stratified
Stratified sampling maintains class proportions in train/test splits, critical for imbalanced classification tasks. Prevents evaluation bias from skewed splits.
Which pattern enables microservices to communicate asynchronously using message queues?
- REST APIs
- Event-Driven Architecture
- gRPC
- Both B and C
Answer: Event-Driven Architecture
Event-driven architecture uses message brokers (Kafka, RabbitMQ) for decoupled, asynchronous service communication. Enables scalability, resilience, and real-time processing.
Content Delivery Networks cache content at edge locations to reduce latency for global users.
- True
- False
Answer: True
CDNs (CloudFront, Cloud CDN) distribute content to edge locations near users, reducing latency and origin load. Critical for global application performance and user experience.
Which service provides managed relational databases with automatic backups and scaling?
- RDS
- Cloud SQL
- Both A and B
- Neither
Answer: Both A and B
Managed databases (AWS RDS, GCP Cloud SQL) handle provisioning, patching, backups, scaling. Reduces operational overhead vs self-managed databases. Critical for cloud application development.
The process of documenting and analyzing security incidents for improvement is called Post-________ Review.
Answer: Incident
Post-incident review captures lessons learned: what happened, response effectiveness, root causes, improvements. Critical for continuous security program maturity.
Which technique identifies phishing emails by analyzing sender reputation and content patterns?
- SPF/DKIM
- Machine Learning
- Both A and B
- Neither
Answer: Both A and B
Email security combines: SPF/DKIM for authentication, ML for content analysis, heuristics for known patterns. Layered defense critical for phishing protection.
A/B testing compares model versions in production to measure business impact.
- True
- False
Answer: True
A/B testing randomly assigns users to model variants, measuring metrics like conversion, engagement. Critical for data-driven model iteration and business value validation.
Which practice ensures ML models are versioned alongside code and data for reproducibility?
- DVC
- MLflow
- Both A and B
- Neither
Answer: Both A and B
MLOps tools: DVC versions data and models, MLflow tracks experiments and deployments. Combined with Git for end-to-end reproducibility. Critical for enterprise ML governance.
The technique that enables LLMs to learn from feedback without explicit labels is called ________ Learning.
Answer: Reinforcement / RLHF
Reinforcement Learning from Human Feedback (RLHF) trains reward models from human preferences, then optimizes LLM to maximize rewards. Critical for aligning AI with human values.
Prompt engineering optimizes LLM performance by crafting effective input instructions.
- True
- False
Answer: True
Prompt engineering: clear instructions, examples, formatting, chain-of-thought. Low-cost method to improve LLM outputs without retraining. Critical for practical LLM applications.
Which technique enables LLMs to generate structured outputs like JSON from natural language?
- Function Calling
- Structured Output Parsing
- Both A and B
- Neither
Answer: Both A and B
Structured output: function calling defines schemas for LLM responses, parsing libraries validate/extract structured data. Critical for integrating LLMs with APIs and databases.
The international framework for cross-border data flows and digital trade is being developed by ________.
Answer: WTO / OECD
WTO e-commerce negotiations and OECD digital economy work address cross-border data flows, digital taxation, consumer protection. India actively participates in shaping global digital trade rules.
Which principle ensures technology regulations are proportionate to risks posed?
- Proportionality
- Technology Neutrality
- Risk-Based Approach
- All of these
Answer: All of these
Effective tech policy: proportionate to actual risks, technology-neutral (focus on outcomes), risk-based (higher scrutiny for higher-risk activities). Critical for balanced policy design.
The Production Linked Incentive scheme for IT hardware aims to boost domestic manufacturing of laptops and servers.
- True
- False
Answer: True
PLI for IT hardware (2021) provides incentives on incremental sales of laptops, tablets, servers manufactured in India. Aims to reduce imports, create jobs, strengthen electronics ecosystem.
Which body oversees cybersecurity policy and coordination in India?
- CERT-In
- NCIIPC
- Both A and B
- MeitY
Answer: Both A and B
CERT-In handles cyber incident response; NCIIPC (National Critical Information Infrastructure Protection Centre) protects critical infrastructure. Both under MeitY for cybersecurity governance.
The Indian initiative for promoting digital payments and financial inclusion is called ________.
Answer: Digital India / UPI
