Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Event ID 4688 with Command Line Auditing enabled
Why it's wrong here
While this logs the process execution, it often truncates long command lines and does not capture the full script block content.
- ✗
Event ID 1102
Why it's wrong here
This indicates that the audit log was cleared, which is a sign of anti-forensics, not evidence of command execution.
- ✓
Event ID 4104
Why this is correct
Event ID 4104 (PowerShell Script Block Logging) captures the entire code block executed, even if the command is obfuscated or fileless.
- ✗
Event ID 4624
Why it's wrong here
This logs user logon events, not the specific code execution details.
