Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗

Why it's wrong here
Metadata is crucial for analysis.

Why it's wrong here
MTU affects packet fragmentation, not log format.

Why it's wrong here
This is an attack, not a management technique.
- ✓
