- C. Copying files at the OS level takes too long to be practical.
- D. Copying files at the OS level changes the timestamp of the files.
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
Bit-level (or bit-stream) copying captures every bit on the storage media, including files, deleted files, slack space (unused space within a cluster), and unallocated space. This ensures all digital evidence, including artifacts not visible at the OS level, is preserved for analysis.
* Copying at the OS level captures only allocated files visible in the file system, missing deleted files and slack space.
* Bit-level copying is a cornerstone of forensic best practices as specified in NIST SP 800-86 and SWGDE guidelines.
* Timestamp changes and unnecessary information issues are secondary concerns compared to the completeness of evidence.
NEW QUESTION # 32
Which principle of evidence collection states that access to evidence must be tracked from the time it is seized through its use in court?
- A. Event log
- B. Audit log
- C. Evidence record
- D. Chain of custody
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The Chain of Custody (CoC) is the documented and unbroken transfer record of evidence handling, from seizure to presentation in court. It ensures that the evidence has been preserved, controlled, and protected from tampering or alteration.
* Evidence record documents evidence details but is less formal than CoC.
* Event log and audit log are system-generated records and do not replace the formal CoC.

NEW QUESTION # 33
An organization has identified a system breach and has collected volatile data from the system.
Which evidence type should be collected next?
- A. Running processes
- B. File timestamps
- C. Temporary data
- D. Network connections
Answer: D
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
In incident response, after collecting volatile data (such as contents of RAM), the next priority is often to collect network-related evidence such as active network connections. Network connections can reveal ongoing communications, attacker activity, command and control channels, or data exfiltration paths.
* Running processes and temporary data are also volatile but typically collected simultaneously or immediately after volatile memory.
* File timestamps relate to non-volatile data and are collected later after volatile data acquisition to preserve evidence integrity.
* This sequence is supported by NIST SP 800-86 and SANS Incident Handler's Handbook which emphasize the volatility of evidence and recommend capturing network state immediately after memory.
