Computer Hacking Forensic Investigator (CHFI v10) — Question 186

A forensics investigator needs to copy data from a computer to some type of removable media so he can examine the information at another location. The problem is that the data is around 42GB in size. What type of removable media could the investigator use?

Answer options

• A. Blu-Ray single-layer
• B. HD-DVD
• C. Blu-Ray dual-layer
• D. DVD-18

Correct answer: C

Explanation

The correct answer is C, Blu-Ray dual-layer, as it can store up to 50GB of data, making it suitable for the 42GB file size. Although A (Blu-Ray single-layer) can hold 25GB, it is insufficient for this data volume. Both B (HD-DVD) and D (DVD-18) do not meet the required storage capacity for this specific amount of data.
