Which of the following is a strong password practice?
- Using birthdate as password
- Reusing passwords across sites
- Using 12+ characters with mix of types
- Writing password on sticky note
Answer: Using 12+ characters with mix of types
Strong passwords should be at least 12 characters long with uppercase, lowercase, numbers, and special symbols. Avoid personal info, dictionary words, or patterns. Use unique passwords per account and store them in a password manager. Enable two-factor authentication for critical accounts.
The branch of AI focused on enabling computers to understand and process human language is called ________ Processing.
Answer: Natural Language
Natural Language Processing (NLP) combines linguistics, computer science, and AI to enable machines to understand, interpret, and generate human language. Applications include chatbots, translation services, sentiment analysis, voice assistants, and automated content summarization.
Which ISRO launch vehicle is designed for launching heavy communication satellites to Geosynchronous Transfer Orbit?
- PSLV
- GSLV Mk III
- SSLV
- ASLV
Answer: GSLV Mk III
GSLV Mk III (now called LVM3) is ISRO's heavy-lift launch vehicle capable of placing 4-ton class satellites into GTO. It was used for Chandrayaan-2, Chandrayaan-3, and OneWeb satellite launches. PSLV handles lighter polar orbits; SSLV is for small satellites; ASLV was retired.
A byte consists of 8 bits.
- True
- False
Answer: True
A byte is a unit of digital information that most commonly consists of 8 bits. This standard allows representation of 256 values (0-255), sufficient for ASCII characters. Larger units: Kilobyte (1024 bytes), Megabyte (1024 KB), etc. Some historical systems used different byte sizes, but 8-bit byte is now universal.
Which payment system in India enables instant money transfer using mobile number and MMID?
- NEFT
- RTGS
- IMPS
- ECS
Answer: IMPS
IMPS (Immediate Payment Service) enables instant interbank electronic fund transfer 24x7 using mobile number + MMID (Mobile Money Identifier) or account number + IFSC. Developed by NPCI, it supports transfers up to ₹5 lakh. NEFT/RTGS have timing restrictions; ECS is for bulk/recurring payments.
In programming, a loop that executes at least once regardless of condition is called a ________ loop.
Answer: do-while
do-while loop checks the condition AFTER executing the loop body, guaranteeing at least one execution. In contrast, while and for loops check condition BEFORE execution, potentially skipping the body entirely if condition is initially false. Syntax varies by language but logic remains consistent.
Which authentication factor is represented by 'something you are'?
- Password
- Smart Card
- Fingerprint
- Security Token
Answer: Fingerprint
Authentication factors: 1) Something you know (password/PIN), 2) Something you have (smart card/token), 3) Something you are (biometrics like fingerprint, iris, face). Multi-factor authentication combines two or more factors for enhanced security. Fingerprint is a biometric ('something you are') factor.
Edge computing processes data closer to the source of generation rather than sending all data to centralized cloud servers.
- True
- False
Answer: True
Edge computing brings computation and data storage closer to IoT devices and data sources, reducing latency, bandwidth usage, and improving real-time processing. Critical for autonomous vehicles, industrial IoT, and smart cities where milliseconds matter. Complements, not replaces, cloud computing.
The protocol used for sending emails from a client to a server is ________.
Answer: SMTP
SMTP (Simple Mail Transfer Protocol) is used for sending emails from client to server or between mail servers. POP3 and IMAP are used for retrieving emails from server to client. SMTP typically uses port 25 (or 587 for secure submission).
Which file extension is typically associated with executable files in Windows?
- .txt
- .exe
- .jpg
Answer: .exe
.exe (executable) files contain programs that can be run directly by the Windows operating system. Users should be cautious opening .exe files from untrusted sources as they can contain malware. Other extensions: .txt (text), .pdf (document), .jpg (image) are data files, not executables.
VoLTE stands for Voice over Long Term Evolution and enables HD voice calls over 4G networks.
- True
- False
Answer: True
VoLTE (Voice over LTE) allows voice calls to be transmitted as data packets over 4G networks, enabling faster call setup, HD voice quality, and simultaneous voice+data usage. Unlike traditional calls that drop to 2G/3G, VoLTE maintains 4G connectivity throughout the call.
Which platform enables citizens to participate in governance by sharing ideas and giving feedback to the government?
- DigiLocker
- MyGov
- UMANG
- e-Taal
Answer: MyGov
MyGov is a citizen engagement platform launched under Digital India that allows Indians to participate in policy discussions, submit ideas, vote on proposals, and provide feedback on government initiatives. It fosters collaborative governance and transparent decision-making.
A type of attack where hackers intercept communication between two parties without their knowledge is called ________-in-the-Middle attack.
Answer: Man
Man-in-the-Middle (MitM) attack occurs when attackers secretly relay and possibly alter communication between two parties who believe they are directly communicating. Prevention includes using HTTPS, VPNs, certificate pinning, and avoiding public Wi-Fi for sensitive transactions.
Which satellite series is used for Earth observation and remote sensing in India?
- INSAT
- GSAT
- CARTOSAT
- IRNSS
Answer: CARTOSAT
CARTOSAT series satellites are dedicated to Earth observation and remote sensing with high-resolution cameras for cartography, urban planning, and resource monitoring. INSAT is for communication/weather, GSAT for communication, and IRNSS/NavIC for navigation.
Cache memory is slower than main RAM but faster than CPU registers.
- True
- False
Answer: False
Cache memory is FASTER than main RAM but SLOWER than CPU registers. Speed hierarchy: CPU Registers (fastest) > L1 Cache > L2 Cache > L3 Cache > RAM > SSD > HDD (slowest). Cache stores frequently accessed data to reduce CPU wait time and improve system performance.
Which AI technique is used for generating realistic images, videos, or text by learning data patterns?
- Decision Trees
- Generative Adversarial Networks
- Linear Regression
- K-Means Clustering
Answer: Generative Adversarial Networks
GANs (Generative Adversarial Networks) consist of two neural networks - a generator that creates fake data and a discriminator that evaluates authenticity. They compete to improve output quality. Used in deepfakes, art generation, drug discovery, and data augmentation. Ethical concerns include misinformation.
The maximum transaction limit for UPI payments as per RBI guidelines (2026) is ₹________ for most categories.
Answer: 1,00,000
As of 2026, the standard UPI transaction limit is ₹1 lakh per transaction for most categories. Some categories like capital market, insurance, and mutual funds have higher limits (₹2-5 lakh). Limits may vary by bank and user risk profile. Always check latest RBI notifications for updates.
IPv6 addresses are 128-bit long, compared to 32-bit for IPv4.
- True
- False
Answer: True
IPv6 uses 128-bit addresses (e.g., 2001:0db8:85a3::8a2e:0370:7334) providing approximately 3.4×10^38 unique addresses, solving IPv4 exhaustion. IPv4 uses 32-bit addresses (e.g., 192.168.1.1) allowing ~4.3 billion addresses. IPv6 also offers improved security and auto-configuration.
Which SQL clause is used to filter groups after aggregation?
- WHERE
- HAVING
- GROUP BY
- ORDER BY
Answer: HAVING
HAVING clause filters results after GROUP BY aggregation, while WHERE filters rows before grouping. Example: SELECT dept, AVG(salary) FROM emp GROUP BY dept HAVING AVG(salary) > 50000. WHERE cannot be used with aggregate functions directly.
A security approach that assumes no user or device is trusted by default, even inside the network, is called ________ Trust.
Answer: Zero
Zero Trust is a cybersecurity framework that requires strict identity verification for every person and device accessing resources on a private network, regardless of location. It follows 'never trust, always verify' principle, using micro-segmentation, least-privilege access, and continuous monitoring.
