- A
Reboot systems to capture volatile memory
Why wrong: Rebooting can alter evidence and is not a preservation technique.
- B
Create forensic bit-for-bit images of affected systems
Forensic images preserve the exact state for analysis and litigation.
- C
Issue a legal hold to prevent deletion of relevant data
Legal holds ensure that data is preserved for potential litigation.
- D
Disconnect affected systems from the network immediately
Why wrong: Disconnecting may preserve data but could also cause loss of volatile evidence; imaging is preferred.
- E
Delete temporary files to free up space
Why wrong: Deleting files destroys potential evidence.

KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the CISM exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
