Digital Forensic Certification Practice Exam

According to the order of volatility, what is the correct sequence with the most volatile data first?

1. 4 -> 1 -> 3 -> 5 -> 2 -> 7 -> 6

2. 4 -> 1 -> 5 -> 3 -> 2 -> 6 -> 7

3. 4 -> 2 -> 1 -> 5 -> 3 -> 7 -> 6

4. 4 -> 1 -> 2 -> 5 -> 3 -> 7 -> 6

The correct answer is: 4 -> 1 -> 3 -> 5 -> 2 -> 7 -> 6

In digital forensics, understanding the order of volatility is crucial for preserving evidence. The correct response emphasizes that the most volatile data should be prioritized during the evidence collection process. This sequence is based on the likelihood that the data will change or be lost over time, which is fundamental in ensuring that the most critical information is captured first for analysis. Typically, the most volatile data includes information that resides in RAM, as it is temporary and will be lost once the power is turned off. This is often followed by processes, network connections, and eventually stable data stored on hard drives or other long-term storage. In this sequence, retaining the integrity of the data by securing the most ephemeral forms allows forensic analysts to gather the most relevant evidence before it becomes inaccessible. The specific ordering in the chosen sequence encapsulates this principle by placing the most volatile data at the forefront, ensuring that evidence is collected in a manner that maximizes the chance of preservation and minimizes the risk of data loss. Each component of the sequence reflects a systematic approach to addressing various data types, starting with those that are most at risk of being altered or erased and progressing to less volatile sources. This approach is standard practice in digital forensic investigations and is critical for maintaining the credibility of the evidence collected.
