Which technique protects ML models from adversarial attacks by training with perturbed inputs?
- Adversarial Training
- Defensive Distillation
- Both A and B
- Neither
Answer: Both A and B
Adversarial training includes adversarial examples in training data; defensive distillation smooths model outputs. Both improve robustness against adversarial attacks.
The pattern of gradually shifting traffic between application versions for safe deployments is called ________ Release.
- Circular
- Frequency
- IPR / Intellectual Property Rights
- Canary
Answer: Canary
Canary Release deploys new version to small user subset, monitors metrics, gradually expands if stable. Reduces risk vs big-bang releases.

- Shukrayaan-1
- Mangalyaan-2
- Aditya-L2
- Gaganyaan-2
Answer: Shukrayaan-1
Shukrayaan-1 is India's planned Venus orbiter mission (target launch ~2028) to study the planet's thick atmosphere, surface processes, and solar wind interactions.
The frequency band used for high-bandwidth satellite internet with higher rain attenuation is ________-band.
- Artificial Intelligence
- Ka
- Virtualization
- Modernisation Programme / DILRMP
Answer: Ka
Ka-band (26.5-40 GHz) offers high bandwidth for satellite broadband but susceptible to rain attenuation. Requires adaptive coding and ground station diversity.
The authority that adjudicates disputes under the DPDP Act 2023 is called Data Protection ________ of India.
- Platform
- Oxygen / ISRU
- Board
- Artemis
Answer: Board
Data Protection Board of India is independent regulatory body established under DPDP Act 2023 to adjudicate disputes, impose penalties, enforce compliance.
The DPDP Act 2023 applies extraterritorially to processing related to Indian individuals.
- True
- False
Answer: True
DPDP Act governs processing of digital personal data: (1) within India, and (2) outside India if offering goods/services or profiling individuals in India.
Model inversion attacks reconstruct training data from model outputs, posing privacy risks.
- True
- False
Answer: True
Model inversion exploits model predictions to infer sensitive training data attributes. Mitigation: differential privacy, output perturbation, access controls. Critical for privacy-preserving ML.
Which cloud pattern enables automatic failover between regions for high availability?
- Multi-Region Active-Active
- Pilot Light
- Warm Standby
- Backup and Restore
Answer: Multi-Region Active-Active
Active-active architecture runs full workload in multiple regions simultaneously, enabling instant failover with zero RPO/RTO. Critical for mission-critical systems requiring maximum resilience.
A security event that compromises the confidentiality, integrity, or availability of data is called a ________.
- RTI Online
- Function
- Breach
- kube-scheduler
Answer: Breach
Security Breach is an incident where unauthorized access, disclosure, alteration, or destruction of data occurs. Requires immediate containment, investigation, notification (as per laws like DPDP Act 2023), and remediation. Prevention: defense-in-depth, monitoring, incident response planning, and employee training.
Which of the following is a non-impact printer?
- Dot Matrix
- Inkjet
- Daisy Wheel
- Line Printer
Answer: Inkjet
Inkjet printers spray tiny ink droplets without physical contact with paper (non-impact). Laser printers use toner and electrostatic charges. Impact printers (Dot Matrix, Daisy Wheel, Line) strike ribbon against paper, producing noise but capable of multi-part forms. Inkjet/Laser dominate home/office use.
UPI Lite enables small-value transactions without entering UPI PIN for faster checkout.
- True
- False
Answer: True
UPI Lite is an on-device wallet for small transactions (up to ₹500 per transaction, ₹4000 daily balance). Allows PIN-less payments for quick checkout at merchants, reducing dependency on bank server availability. Balance is loaded from linked bank account; ideal for transit, food, and micro-payments.
The technology that uses algorithms to recommend products based on user behavior is called ________ Filtering.
- Ransomware
- Collaborative
- Carbon
- LLDP / CDP
Answer: Collaborative
Collaborative Filtering recommends items by analyzing patterns from similar users (user-based) or similar items (item-based). Used by Amazon, Netflix, Spotify. Hybrid systems combine with content-based filtering. Privacy-preserving techniques like federated learning are emerging to protect user data while personalizing recommendations.
Which ISRO center is located in Sriharikota and handles satellite launches?
- VSSC
- URSC
- SDSC-SHAR
- LPSC
Answer: SDSC-SHAR
SDSC-SHAR (Satish Dhawan Space Centre - Sriharikota) is ISRO's primary launch port in Andhra Pradesh. Handles all satellite and human spaceflight launches from Indian soil. Named after former ISRO chairman. Strategic coastal location enables safe launch trajectories over Bay of Bengal.
5G networks support network slicing to create virtual networks for specific use cases.
- True

Which normal form requires that every non-key attribute is fully functionally dependent on the primary key?
- 1NF
- 2NF
- 3NF
- BCNF
Answer: 2NF
Second Normal Form (2NF) requires: 1) Table is in 1NF, and 2) No partial dependency (non-key attributes must depend on entire primary key, not part of composite key). Eliminates redundancy from partial dependencies. Further normalization to 3NF removes transitive dependencies.
