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

- ✗
Centralized logging
Why it's wrong here
Logging detects movement, it does not prevent it.

Network segmentation
Why this is correct
Segmentation isolates traffic and limits lateral movement.
