Exam 312-49v10 topic 1 question 332 discussion

Answer: C. Bit Stream Imaging Explanation of Options: A. Data Extraction: Incorrect – Involves retrieving specific data, not creating full replicas. B. Backup: Incorrect – Copies files, but not an exact replica of the media. C. Bit Stream Imaging: Correct – Creates a sector-by-sector replica of the media. D. Data Deduplication: Incorrect – Eliminates duplicate data, not related to evidence replication.

The correct answer is C. Bit Stream Imaging. Bit Stream Imaging, also known as bit-for-bit imaging or sector-by-sector imaging, is a technique used to create an exact replica of a digital evidence media, such as a hard drive or USB drive. This process creates a identical copy of the original media, including all data, metadata, and even blank spaces. Here's a brief overview of the other options: A. Data Extraction: This technique extracts specific data from a digital evidence media, but does not create a complete replica. B. Backup: A backup is a copy of important data, but it's not a bit-for-bit copy of the entire media. D. Data Deduplication: This technique removes duplicate data to reduce storage size, but does not create a replica of the media.
