In digital forensics, what is the primary purpose of data acquisition?

To create a byte-for-byte copy of digital evidence while preserving its integrity

To analyze the data on a suspect's device and identify malicious activity

To permanently delete data from a storage device to prevent unauthorized access

To repair corrupted files on a storage device so they can be accessed

How can an examiner verify that a bit-for-bit duplicate matches the original storage media?

By ensuring the duplicate was created using the same acquisition tool

By comparing the cryptographic hash values of the original and the duplicate

By visually inspecting the contents of both drives

By checking that the duplicate has the same file names and sizes

A forensic examiner needs to acquire only the active files and the file system metadata from a large server drive, without imaging the entire drive, to quickly identify which files were accessed recently. The examiner wants to ensure the original drive is not modified. Which acquisition method and tool should be used?

Physical acquisition using dd without a write blocker.

Sparse acquisition using Guymager to capture only the unallocated space.

Live acquisition using a memory imaging tool.

Logical acquisition using FTK Imager with a hardware write blocker.

Which scenario would most likely require live acquisition rather than static acquisition?

A laptop that was found powered off at a crime scene

A desktop computer that has been seized and is in the forensic lab

A mobile phone that is turned off and has a locked screen

A server that must remain online to provide critical services

A forensic examiner is acquiring evidence from a corporate server that is part of a legal case. The examiner has completed the acquisition and hashes. The examiner needs to ensure the evidence is admissible in court. Which additional step is most critical?

Use a different hashing algorithm to double-check the hash.

Document the chain of custody, including who handled the evidence and when.

Store the image on a network share for easy access.

Encrypt the image file to protect it from unauthorized access.
