Which practice ensures ML models are tested for security vulnerabilities before deployment?
- Adversarial Testing
- Penetration Testing
- Both A and B
- Neither
Answer: Both A and B
ML security testing: adversarial examples test robustness, penetration testing finds implementation flaws. Critical for secure AI deployment in sensitive domains.
Which technique enables LLMs to generate code from natural language descriptions?
- Code LLMs
- Program Synthesis
- Both A and B
- Neither
Answer: Both A and B
Code LLMs (Codex, CodeLlama) trained on code corpora enable natural language to code generation. Program synthesis automates code creation from specifications. Critical for developer productivity tools.
Which body regulates telecommunications services and spectrum allocation in India?

- DoT
- TSDSI
- MeitY
Answer: TRAI
Telecom Regulatory Authority of India (TRAI) recommends policies, regulates tariffs, ensures QoS, and manages spectrum auctions. Critical for telecom sector governance questions.
Which technique handles high-cardinality categorical variables efficiently?
- One-Hot Encoding
- Target Encoding
- Embedding Layers
- All of these
Answer: All of these
High-cardinality handling: one-hot for low cardinality, target encoding for medium, embeddings for high (deep learning). Choice depends on model type and cardinality. Critical for feature preprocessing.
Which metric measures the ability of a classifier to distinguish between classes?
- Accuracy
- Precision
- ROC-AUC
- F1 Score
Answer: ROC-AUC
ROC-AUC (Receiver Operating Characteristic - Area Under Curve) measures classifier performance across all thresholds, robust to class imbalance. Critical for evaluating binary classification models.
Which disaster recovery strategy maintains a fully operational standby environment in another region?
- Backup and Restore
- Pilot Light
- Warm Standby
- Multi-Site Active-Active
Answer: Multi-Site Active-Active
Active-active runs full workload in multiple regions simultaneously, enabling instant failover with zero RPO/RTO. Highest cost but maximum resilience. Critical for mission-critical systems.
Which pattern enables automatic scaling of resources based on demand metrics?
- Auto-scaling
- Load Balancing
- Both A and B
- Neither
Answer: Both A and B
Auto-scaling adjusts resource count based on CPU, memory, or custom metrics; load balancing distributes traffic across instances. Combined for elastic, resilient cloud applications.
Which tool automates vulnerability scanning and prioritization for remediation?
- Nessus
- Qualys
- Both A and B
- Neither
Answer: Both A and B
Vulnerability scanners (Nessus, Qualys, OpenVAS) identify security weaknesses, prioritize by risk, and track remediation. Critical for proactive security posture management.
Which practice detects when model performance degrades due to changing data distributions?
- Data Drift Detection
- Concept Drift Detection
- Both A and B
- Neither
Answer: Both A and B
Data drift: input feature distribution changes; concept drift: relationship between features and target changes. Monitoring both enables timely model retraining. Critical for production ML reliability.
Which technique enables LLMs to answer questions by retrieving relevant documents?
- Fine-tuning
- RAG
- Prompt Engineering
- All of these
Answer: RAG
Retrieval-Augmented Generation (RAG) combines LLMs with vector database retrieval, grounding responses in verified sources. Reduces hallucinations and enables knowledge updates without retraining.
Which framework provides guidelines for interoperable digital identity systems globally?
- ISO/IEC 24760
- W3C DID
- Both A and B
- Neither
Answer: Both A and B
ISO/IEC 24760 provides identity management framework; W3C DID enables decentralized identifiers. Both support interoperable, privacy-preserving digital identity systems. Critical for identity policy questions.
Which initiative promotes open-source software for public sector digital transformation?
- Digital India
- FOSS Policy
- Both A and B
- Neither
Answer: Both A and B
Digital India encourages FOSS adoption for cost-effectiveness, security, and vendor independence. MeitY's FOSS policy provides guidelines for government use. Critical for sustainable digital governance.
Which technique handles class imbalance by generating synthetic minority samples?
- Undersampling
- Oversampling
- SMOTE
- Class Weighting
Answer: SMOTE
SMOTE (Synthetic Minority Over-sampling Technique) creates synthetic examples by interpolating between minority class neighbors. Improves classifier performance on imbalanced data vs simple oversampling.
Which visualization shows relationship between two continuous variables?
- Bar Chart
- Histogram
- Scatter Plot
- Pie Chart
Answer: Scatter Plot
Scatter plots display individual data points for two variables, revealing correlations, clusters, and outliers. Foundation for regression analysis and exploratory data science.
Which technique splits data into training, validation, and test sets to prevent overfitting?
- Cross-Validation
- Holdout Method
- Bootstrap
- All of these
Answer: All of these
Data splitting strategies: holdout (simple split), cross-validation (multiple folds), bootstrap (resampling). Critical for reliable model evaluation and generalization assessment.
Which architecture enables event-driven communication between microservices using message brokers?
- REST APIs
- gRPC
- Event-Driven Architecture
- Monolithic
Answer: Event-Driven Architecture
Event-driven architecture uses message brokers (Kafka, RabbitMQ) for asynchronous, decoupled service communication. Enables scalability, resilience, and real-time processing. Critical for modern distributed systems.
Which service model provides managed Kubernetes for container orchestration?
- IaaS
- PaaS
- CaaS
- SaaS
Answer: CaaS
CaaS (Container as a Service) provides managed Kubernetes (EKS, AKS, GKE) for container deployment, scaling, and management. Abstracts infrastructure while retaining control. Critical for cloud-native development.
Which technique enables automated analysis of malware behavior in isolated environments?
- Static Analysis
- Dynamic Analysis
- Sandboxing
- All of these
Answer: All of these
Malware analysis combines: static (code inspection), dynamic (runtime behavior), sandboxing (isolated execution). Critical for threat intelligence and incident response.
Which detection method identifies threats by analyzing behavior patterns rather than known signatures?
- Signature-based
- Anomaly-based
- Heuristic
- All of these
Answer: Anomaly-based
Anomaly detection establishes baselines of normal behavior and flags deviations, enabling zero-day threat detection. Critical for advanced threat protection in modern SOCs.
Which practice ensures ML models are tested for fairness and bias before deployment?
