- False
Answer: True
DIKSHA (Digital Infrastructure for Knowledge Sharing) is a unified platform by Ministry of Education offering e-content, QR-coded textbooks, teacher training modules, and assessment tools. Supports multilingual access and offline usage. Critical component of NEP 2020's technology-enabled education transformation.
The Agni-P missile is a two-stage solid-fueled ballistic missile with MIRV capability.
- True
- False
Answer: True
Agni-P (Prime) is a new-generation ballistic missile with 1,000-2,000 km range, two solid-propellant stages, canister-launched, and equipped with MIRV (Multiple Independently Targetable Reentry Vehicle) technology. Enhances India's credible minimum deterrence. Critical for defense and strategic studies questions.
A stack data structure can be implemented using an array or a linked list.
- True
- False
Answer: True
Stacks can be implemented with arrays (fixed size, O(1) access) or linked lists (dynamic size, O(1) push/pop at head). Choice depends on requirements: arrays are cache-friendly; linked lists avoid overflow. Understanding implementation trade-offs is important for data structure design questions.
The DPDP Act 2023 applies to processing of personal data outside India if it involves profiling of individuals in India.
- True
- False
Answer: True
DPDP Act has extraterritorial application: it governs processing of digital personal data (1) within India, and (2) outside India if it relates to offering goods/services or profiling individuals in India. Aligns with GDPR's approach. Critical for multinational compliance and data sovereignty questions.
Energy-efficient buildings in India are certified under the GRIHA rating system.
- True
- False
Answer: True
GRIHA (Green Rating for Integrated Habitat Assessment) is India's national rating system for green buildings, developed by TERI and Ministry of New & Renewable Energy. Evaluates energy/water efficiency, waste management, and sustainable materials. LEED is an international alternative. Important for sustainable development questions.
In Linux, the sudo command allows authorized users to execute commands with superuser privileges.
- True
- False
Answer: True
sudo (superuser do) grants temporary elevated privileges to authorized users as defined in /etc/sudoers. Promotes least-privilege security model by avoiding persistent root login. Users authenticate with their own password. Critical concept for secure system administration in technical exams.
CSS Flexbox is designed for one-dimensional layouts (either row or column).
- True
- False
Answer: True
Flexbox handles one-dimensional layouts: arrange items in a row OR column with flexible sizing, alignment, and order. CSS Grid handles two-dimensional layouts (rows AND columns). Both are modern layout systems replacing floats/positioning. Understanding their use cases is important for responsive design questions.
Hash tables provide average-case O(1) time complexity for search, insert, and delete operations.
- True
- False
Answer: True
Hash tables use hash functions to map keys to array indices, enabling average O(1) operations. Worst-case O(n) occurs with many collisions (resolved via chaining/open addressing). Load factor and good hash functions maintain performance. Critical data structure for efficient lookups in real-world applications and exams.
Under the IT Act 2000, intermediaries like social media platforms are liable for third-party content they host.
- True
- False
Answer: False
Section 79 of IT Act provides safe harbor to intermediaries if they: (1) only provide access, (2) don't initiate/modify transmission, (3) observe due diligence and remove content upon actual knowledge.

Green hydrogen is produced by electrolysis of water using renewable electricity.
- True
- False
Answer: True
Green hydrogen is produced via water electrolysis powered by renewable energy (solar, wind), resulting in zero-carbon fuel.
