Which technique enables LLMs to execute code or use external tools for complex tasks?
- Function Calling
- Tool Use
- Both A and B
- Neither
Answer: Both A and B
Function calling/tool use enables LLMs to invoke APIs, run code, query databases for tasks beyond text generation. Critical for building agentic AI systems that interact with real-world systems.
The practice of versioning datasets, models, and code for reproducibility is called ________ Management.
- Inversion
- Supervised
- Artifact / Model Registry
- Quantum
Answer: Artifact / Model Registry
Artifact management (MLflow, DVC) tracks datasets, model versions, hyperparameters, and code commits. Enables reproducibility, auditability, and rollback in ML workflows. Critical for enterprise MLOps.
Which practice ensures ML models are continuously monitored and retrained in production?
- CI/CD
- Model Drift Detection
- A/B Testing
- All of these
Answer: All of these
MLOps combines: CI/CD for automated deployment, drift detection for performance monitoring, A/B testing for validation. Critical for maintaining ML system reliability and business value over time.
Parameter-Efficient Fine-Tuning (PEFT) methods like LoRA reduce compute costs for adapting large models.
- True
- False
Answer: True
PEFT methods (LoRA, Adapter, Prefix-tuning) update small subset of parameters or add lightweight modules, reducing compute/memory vs full fine-tuning. Critical for resource-constrained LLM adaptation.
The technique that enables LLMs to reason step-by-step by generating intermediate thoughts is called Chain-of-________.
- Classification
- Zero Trust
- Thought
- Diffie-Hellman
Answer: Thought
Chain-of-Thought prompting encourages LLMs to generate reasoning steps before final answer, improving performance on complex reasoning tasks. Critical for enhancing LLM reliability in high-stakes applications.
Fine-tuning adapts pre-trained LLMs to specific tasks with smaller datasets.
- True
- False
Answer: True
Fine-tuning updates pre-trained model weights on task-specific data, enabling adaptation to domains like healthcare, legal, or customer service with limited labeled examples. Critical for practical LLM deployment.
Which of the following is NOT a function of an operating system?
- Memory Management
- File System Management
- Compiling Source Code
- Process Scheduling
Answer: Compiling Source Code
Compiling source code is performed by compiler software (like GCC, javac), not the OS. OS functions include: process management, memory management, file system management, device management, security, and user interface. Compilers are application/system software that run ON the OS.
Which ISRO center is responsible for developing launch vehicles?
- VSSC
- URSC
- LPSC
- ISAC
Answer: VSSC
VSSC (Vikram Sarabhai Space Centre), Thiruvananthapuram, is ISRO's lead center for launch vehicle development including PSLV, GSLV, and LVM3. URSC handles satellites, LPSC develops propulsion systems, ISAC integrates satellites. ISRO has multiple specialized centers across India.
A security measure that converts sensitive data into a fixed-size string of characters, which cannot be reversed, is called ________.
- Masked
- LCH Prachand
- Hashing
- Rain
Answer: Hashing
Hashing transforms input data of any size into a fixed-length hash value using algorithms like SHA-256 or MD5. It is one-way (irreversible), used for password storage, data integrity verification, and digital signatures. Unlike encryption, hashed data cannot be decrypted to original form.
Which normal form eliminates transitive dependencies in database design?
- 1NF
- 2NF
- 3NF
- BCNF
Answer: 3NF
Third Normal Form (3NF) requires that a table is in 2NF and has no transitive dependencies (non-key attributes depending on other non-key attributes). This reduces redundancy and update anomalies. BCNF is a stricter version of 3NF handling certain edge cases in dependency relationships.
CoWIN platform was developed exclusively for COVID-19 vaccination management and cannot be repurposed for other health programs.
- True
- False
Answer: False
CoWIN is built on a modular, scalable architecture that can be repurposed for other immunization and health programs. The government has indicated plans to adapt CoWIN for routine vaccination drives, demonstrating the value of building flexible digital public infrastructure for healthcare delivery.
Which technology allows multiple users to share the same frequency band by assigning unique codes?
- FDMA
- TDMA
- CDMA
- OFDMA
Answer: CDMA
CDMA (Code Division Multiple Access) allows multiple users to transmit simultaneously on same frequency by assigning unique spreading codes. Used in 3G networks. FDMA divides frequency, TDMA divides time slots, OFDMA (used in 4G/5G) combines frequency and time division with orthogonal subcarriers.
Antivirus software can detect and remove all types of malware with 100% accuracy.
- True
- False
Answer: False
No antivirus can guarantee 100% detection due to zero-day exploits, polymorphic malware, and advanced persistent threats. Effective security requires layered approach: updated AV, firewall, patches, user awareness, backups, and behavioral analysis. Regular updates improve detection but cannot eliminate all risks.
Which NPCI initiative enables bill payments across multiple categories through a single platform?
- UPI
- BBPS
- AePS
- IMPS
Answer: BBPS
BBPS (Bharat Bill Payment System) is an integrated bill payment platform by NPCI that enables customers to pay recurring bills (electricity, water, gas, DTH, telecom) through multiple channels (online, bank branches, BCs, CSCs). Offers interoperability, instant confirmation, and grievance redressal.
A private network within an organization that uses internet protocols but is accessible only to authorized users is called an ________.
- Maintainable
- Intranet
- Ground Station
- Incident
Answer: Intranet
Intranet is a private network using TCP/IP protocols, accessible only to organization members. It hosts internal websites, documents, and applications. Extranet extends intranet to authorized external users (partners, vendors). Internet is the public global network. Firewalls protect intranets from external threats.
Defragmenting a hard disk improves the performance of SSDs significantly.
- True
- False
Answer: False
Defragmentation rearranges fragmented files on HDDs to improve read/write speed. However, SSDs have no moving parts and access data electronically, so defragmentation provides no benefit and may reduce SSD lifespan due to unnecessary write cycles. Modern OS automatically disables defrag for SSDs.
Which technology uses distributed ledger to record transactions across multiple computers?
- Cloud Computing
- Blockchain
- Edge Computing
- Quantum Computing
Answer: Blockchain
Blockchain is a decentralized, distributed ledger technology where transactions are recorded across multiple nodes, making it tamper-resistant and transparent. Beyond cryptocurrencies, it's used in supply chain, voting, identity management, and smart contracts. Key features: immutability, consensus, cryptography.
NoSQL databases are always better than relational SQL databases for all applications.
- True
- False
Answer: False
Database choice depends on use case. SQL (MySQL, PostgreSQL) excels at structured data, complex queries, and ACID transactions. NoSQL (MongoDB, Cassandra) is better for unstructured data, horizontal scaling, and high-velocity writes. Many systems use both (polyglot persistence) for different needs.
Which frequency band is primarily used for 4G LTE services in India?
- 700 MHz
- 1800 MHz
- 26 GHz
- 60 GHz
Answer: 1800 MHz
India's 4G LTE services primarily use 1800 MHz (Band 3) and 2300 MHz (Band 40) spectrum. 700 MHz is being rolled out for better rural coverage. 26 GHz and 60 GHz are mmWave bands considered for future 5G enhancements, not current 4G deployments.
The process of starting a computer and loading the operating system into memory is called ________.
- Booting
- Gate-All-Around / GAA
- Rain
- Tokenization
Answer: Booting
Booting is the startup sequence when a computer is powered on. BIOS/UEFI performs POST (Power-On Self-Test), locates boot device, loads bootloader, which then loads the OS kernel into RAM. Cold boot = power-on start; warm boot = restart without power cycle.
