The analyst is using the "hexdump" command to view the hexadecimal representation of the file's contents, which can help in identifying the file type or format. By examining the hexadecimal data, the analyst can look for specific patterns or signatures that correspond to known file types or formats. This is a common technique in digital forensics to understand the nature of a file when its format or type is not immediately clear.

If you've done forensics and used the FTK Imager, then you will understand the output of binary value in which you can find the file type. To the right is the file type JFIF, which is an image file. Answer is D

Here the focus is not how we usually use hexdump, it’s about the snippet itself. “Reviews the following output snippet”. The output snippet alone is not sufficient to determine whether the analyst is performing reverse engineering or another type of analysis.

Looking at a hex dump of data is usually done in the context of either debugging, reverse engineering or digital forensics. since its an analyst he/she most likely performing reverse engineering.

Sorry Answer E

Answer B.

Answer is E. The analyst is not asked to debug an application so B is not the correct answer. The analyst is suppose to perform monitoring.

I think that answer should be E. Analyst is conducting Reverse Engineering to check the file content. P.S after asking uncle Google "hexdump command" I recivied following answer: "What does Hexdump command do? Hexdump is a utility that displays the contents of binary files in hexadecimal, decimal, octal, or ASCII. It's a utility for inspection and can be used for data recovery, REVERSE ENGINEERING, and programming"

Hexdump is very helpful utility for debugging and verifying file contents written by any application program.
