Sample questions

Question #1 John works as a C programmer. He develops the following C program: " target="_blank" rel="nofollow noopener">https://www.examtopics.com/assets/media/exam-media/03651/0000200001.png"> His program is vulnerable to a __________ attack.
  • A.
    SQL injection
  • B.
    Denial-of-Service
  • C.
    Buffer overflow
  • D.
    Cross site scripting

Answer: C

Option Analysis: A. SQL injection attacks target improper validation of database input in applications interacting with databases, and are not a vulnerability specific to unsecure C program memory handling, so this option is incorrect. B. Denial-of-Service is a broad category of attacks intended to disrupt service availability, not the specific memory corruption vulnerability associated with poorly written C programs referenced here, so this option is incorrect. C. Buffer overflow is the correct answer, as C lacks built-in memory bounds checking, so unsecure input handling in C programs often allows attackers to write excess data to fixed-length buffers and corrupt adjacent memory for exploitation. D. Cross site scripting attacks exploit improper input sanitization in web applications to inject malicious scripts into end-user browsers, and are unrelated to native C program vulnerabilities, so this option is incorrect. Key Concept: Buffer overflow is a common memory corruption vulnerability in languages like C that lack automatic bounds checking, where excess data written to a fixed-size buffer overwrites adjacent memory to enable arbitrary code execution, service disruption, or other malicious outcomes.

Question #2 DRAG DROP - Drag and drop the terms to match with their descriptions. Select and Place: " target="_blank" rel="nofollow noopener">https://www.examtopics.com/assets/media/exam-media/03651/0000300001.jpg">
  • A.
    对
  • B.
    错

Answer: A

Analysis: Correct matches ordered by the description rows: 1. Trojan horse, 2. Ping sweep, 3. Spamware, 4. Backdoor. A Trojan horse is malware that disguises itself as legitimate software to deceive users into running it, matching the first description. A ping sweep is a network scanning method used to identify live hosts in an IP range, matching the second description. Spamware is purpose-built to distribute automated spam email, matching the third description. A backdoor provides attackers with unauthenticated access to a target system, matching the fourth description. Key Concept: This question evaluates knowledge of core definitions for common malware types and network reconnaissance techniques as specified in the EC-Council 312-38 Certified Network Defender exam objectives.

Question #3 FILL BLANK -Fill in the blank with the appropriate term. ________________________ is the complete network configuration and information toolkit that uses multi-threaded and multi-connection technologies in order to be very fast and efficient.

Answer: NetScanTools Pro

Analysis: The correct answer is NetScanTools Pro. This utility is a full-suite network configuration and information toolkit built with multi-threaded and multi-connection technologies to execute network scanning, diagnostics, and auditing tasks far faster than single-threaded alternatives. It includes all core functions required for network assessment, administration, and defense use cases aligned with 312-38 exam objectives. Key Concept: Multi-threaded network assessment toolkits such as NetScanTools Pro are core efficient utilities for network configuration auditing and information gathering covered in the EC-Council 312-38 Certified Network Defender curriculum.

Question #4 FILL BLANK -Fill in the blank with the appropriate term. A _______________device is used for uniquely recognizing humans based upon one or more intrinsic physical or behavioral traits.
  • .

Answer: biometric

Analysis: The correct answer is biometric. Biometric devices identify or authenticate individuals using unique inherent physical traits such as fingerprints or iris patterns, or behavioral traits such as voice cadence or typing rhythm, which directly matches the definition provided in the question. These devices are widely used for both physical facility access control and logical network access control to mitigate the risk of unauthorized access via credential spoofing. Key Concept: Biometric authentication is an access control mechanism covered in the EC-Council 312-38 Certified Network Defender exam that leverages unique intrinsic user physical or behavioral traits to validate user identity and restrict access to sensitive networks and physical assets.

Question #5 Which of the following analyzes network traffic to trace specific transactions and can intercept and log traffic passing over a digital network? Each correct answer represents a complete solution. Choose all that apply.
  • A.
    Wireless sniffer
  • B.
    Spectrum analyzer
  • C.
    Protocol analyzer
  • D.
    Performance Monitor

Answer: AC

Option Analysis: A. A wireless sniffer intercepts, logs, and analyzes wireless network traffic to trace specific transactions traversing wireless digital networks, so this option is correct. B. A spectrum analyzer measures radio frequency signal strength, interference, and other RF properties rather than analyzing network traffic content or tracing specific transactions, so this option is incorrect. C. A protocol analyzer (packet sniffer) captures, decodes, logs, and analyzes wired or wireless digital network traffic to trace specific individual transactions, so this option is correct. D. Performance Monitor is a tool designed to track aggregate system and network performance metrics such as bandwidth usage and CPU utilization, and does not intercept or analyze individual network traffic to trace specific transactions, so this option is incorrect. Key Concept: This question assesses the ability to differentiate between dedicated network traffic capture and analysis tools that support traffic interception, logging, and transaction tracing versus other network monitoring and measurement tools, as outlined in the EC-Council 312-38 Certified Network Defender exam domains.
