Question

What is the proper order of volatility: A. Registers and cache B. Routing tables C. ARP cache D. Process table E. Kernel statistics and modules

Option 1: B, C, A, D, E
Option 2: A, B, C, D, E
Option 3: C, A, D, B, E

Answer 1

The proper order of volatility from most to least is ARP cache, registers and cache, process table, routing tables, and kernel statistics and modules. The correct sequence is crucial for digital forensics and incident response.

Step-by-step explanation:

The proper order of volatility in computing, in the context of digital forensics and incident response, is as follows:

1. Registers and cache
2. Routing tables
3. ARP cache
4. Process table
5. Kernel statistics and modules

This order represents the sequence from most volatile to least volatile data storage on a computer system. Volatility in this context refers to the persistence of data when power is removed from the system. Volatile data is lost first, hence the correct order of volatility generally starts with CPU registers and cache, then system and network tables such as ARP and routing tables, followed by process-related information, and finally system-related information like kernel statistics and loaded modules.

Based on the options provided in the question, Option 1 listed as B, C, A, D, E is incorrect because registers and cache are the most volatile and should come before routing tables and ARP cache. Option 2 listed as A, B, C, D, E is also incorrect, as the correct order should start with the most volatile (A) but does not follow the rest correctly. Therefore, the correct order of volatility is reflected in Option 3: C, A, D, B, E, starting with the most volatile, which is the ARP cache, then moving to registers and cache, and so on.
