B. Capturing volatile memory
C. Examining device configuration files and logs
D. Upgrading firmware
Answer: C
Explanation: Examining configuration files and logs is crucial because these contain the
necessary information to reconstruct events and identify anomalies.
9. How do deobfuscation tools aid forensic investigators?
Options:
A. By automating software updates
B. By converting obfuscated data into readable format
,C. By encrypting sensitive files
D. By managing network traffic
Answer: B
Explanation: Deobfuscation tools help convert encoded or scrambled data into a readable format,
which is essential for identifying malicious code.
10. What is one common characteristic of antiforensic techniques?
Options:
A. Simplifying the investigation process
B. Hiding or altering evidence
C. Enhancing network performance
D. Documenting file metadata
Answer: B
Explanation: Antiforensic techniques are designed to hinder forensic investigations by hiding or
altering evidence, making it harder to determine the true cause of an incident.
11. Which of the following is a typical component of a root cause analysis report?
Options:
A. Incident cost analysis
B. Recovery time estimates
C. Detailed event timeline
D. User satisfaction surveys
Answer: C
Explanation: A detailed timeline is a vital part of a root cause analysis, as it helps explain the
sequence of events leading to the incident.
**12. Forensic analysis of network devices primarily involves: **
Options:
A. Physical device repair
B. Analysis of device logs and configurations
C. Redesigning network architecture
D. Installing new operating systems
Answer: B
Explanation: Forensic analysis on network devices focuses on examining logs and configurations
to uncover evidence of compromise or misconfiguration.
13. What is the main purpose of employing hex editors in forensic investigations?
Options:
A. To improve graphical interfaces
B. To edit video files
C. To examine and modify binary data
D. To manage user accounts
Answer: C
Explanation: Hex editors are specialized tools that allow investigators to view and edit binary
data, which is critical in analyzing file structures and detecting anomalies.
, 14. Which of the following best describes the use of disassemblers in forensic analysis?
Options:
A. To compress files
B. To convert executable code into assembly language
C. To encrypt data
D. To manage databases
Answer: B
Explanation: Disassemblers convert binary executables into human-readable assembly code,
which aids in understanding how a program operates and identifying malicious behavior.
15. How do memory forensics tools contribute to DFIR investigations?
Options:
A. By backing up data
B. By analyzing the contents of volatile memory
C. By monitoring network traffic
D. By scheduling scans
Answer: B
Explanation: Memory forensics tools analyze volatile memory to uncover transient artifacts that
can provide insights into running processes and malware behavior.
16. Which challenge is most associated with collecting evidence from cloud-based
virtualized environments?
Options:
A. Inadequate encryption protocols
B. Dynamic and distributed data locations
C. Overheating of servers
D. Limited user access
Answer: B
Explanation: Cloud environments often have dynamic and distributed data storage, which makes
collecting and correlating evidence more complex.
