Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Reboot systems to capture volatile memory
Why it's wrong here
Rebooting can alter evidence and is not a preservation technique.
- ✓
Create forensic bit-for-bit images of affected systems
Why this is correct
Forensic images preserve the exact state for analysis and litigation.
- ✓
Issue a legal hold to prevent deletion of relevant data
Why this is correct
Legal holds ensure that data is preserved for potential litigation.
- ✗
Disconnect affected systems from the network immediately
Why it's wrong here
Disconnecting may preserve data but could also cause loss of volatile evidence; imaging is preferred.
