Here is a sneak peek of the questions included in this test set. Test your preparation by viewing the answer and detailed explanation before starting the timed exam.

What is a SQL Injection (SQLi) attack in database and web application security?

डेटाबेस और वेब एप्लिकेशन सुरक्षा में SQL इंजेक्शन (SQLi) हमला क्या है?

Injecting hardware viruses into MySQL serversMySQL सर्वर में हार्डवेयर वायरस इंजेक्ट करना

Encrypting SQL tables with passwordsपासवर्ड के साथ SQL तालिकाओं को एन्क्रिप्ट करना

A code injection vulnerability where malicious SQL statements are inserted into user input fields to manipulate backend database queries unauthorizedlyएक कोड इंजेक्शन भेद्यता जहां बैकएंड डेटाबेस क्वेरीज़ में अनधिकृत रूप से हेरफेर करने के लिए उपयोगकर्ता इनपुट फ़ील्ड में दुर्भावनापूर्ण SQL स्टेटमेंट डाले जाते हैं

Deleting SQL databases from terminalटर्मिनल से SQL डेटाबेस हटाना

Correct Answer: Option C

Explanation:

SQL injection occurs when unsanitized user inputs are concatenated into dynamic queries, allowing attackers to bypass authentication or extract sensitive data.

SQL इंजेक्शन तब होता है जब असंक्रमित उपयोगकर्ता इनपुट को गतिशील प्रश्नों में संयोजित किया जाता है, जिससे हमलावरों को प्रमाणीकरण को बायपास करने या संवेदनशील डेटा निकालने की अनुमति मिलती है।

How can web developers and database programmers definitively PREVENT SQL Injection attacks in Python applications?

वेब डेवलपर्स और डेटाबेस प्रोग्रामर निश्चित रूप से पायथन अनुप्रयोगों में SQL इंजेक्शन हमलों को कैसे रोक सकते हैं?

By using Parameterized Queries (Prepared Statements) with placeholders (`%s`) instead of string concatenationस्ट्रिंग संयोजन के बजाय प्लेसहोल्डर्स (`%s`) के साथ पैरामीटरयुक्त क्वेरीज़ (तैयार कथन) का उपयोग करके

By using only `CHAR` datatypes in tablesतालिकाओं में केवल `CHAR` डेटाटाइप का उपयोग करके

By running MySQL on port 80पोर्ट 80

By deleting all admin accountsपर MySQL चलाकर सभी व्यवस्थापक खातों को हटाकर

Correct Answer: Option A

Explanation:

Parameterized queries separate SQL code structure from user data, ensuring input parameters are treated strictly as data literals rather than executable SQL.

पैरामीटरयुक्त क्वेरीज़ उपयोगकर्ता डेटा से SQL कोड संरचना को अलग करती हैं, यह सुनिश्चित करती हैं कि इनपुट पैरामीटर को निष्पादन योग्य SQL के बजाय डेटा शाब्दिक के रूप में सख्ती से माना जाता है।

How Chapter-Wise Online CBT Tests Build Winning Habits for Future Competitive Exams

Focused chapter-wise CBT practice builds the speed, mental stamina, and analytical discipline required to ace CUET, JEE Main, NEET UG, NDA, CA Foundation, and College Entrance Exams.

Competitive Edge

Real-Time Clock Awareness & Pacing

समय प्रबंधन एवं गति नियंत्रण

In school examinations, students write answers without active pacing. In national entrance tests, students have barely 45-60 seconds per MCQ. Practicing with a 20-minute timer instills instinctive time-budgeting and prevents last-minute exam panic.

Mastery of the Elimination Technique

विकल्प निष्कासन विधि में दक्षता

Top rankers in competitive exams rarely compute every problem blindly. They spot subtle traps, evaluate extreme values, and eliminate 2 out of 4 distractors within seconds. Our 4-option sets teach critical distractor analysis.

CBT Screen Stamina & Digital Comfort

कंप्यूटर आधारित परीक्षा का सहज अभ्यास

Almost all major national exams (CUET, JEE, NEET, SSC, Banking) are 100% computer-based. Students who only study on paper experience eye strain and navigation mistakes on exam day. Early CBT practice creates effortless digital fluency.

Immunity to Negative Marking

सटीकता और नकारात्मक अंकन से सुरक्षा

Careless errors—such as misreading "NOT" or "EXCEPT"—ruin thousands of competitive aspirations each year. Regular objective testing builds the habit of double-checking question keywords before locking answers.

Instant Diagnostic Feedback Loop

तत्काल त्रुटि निवारण एवं आत्म-मूल्यांकन

Traditional paper tests take weeks to grade, by which time the student has forgotten their thought process. TargetExams provides instant scorecards and step-by-step solutions while the conceptual puzzle is still fresh.
