Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Elimination of the need for any firewalls or security monitoring
Why it's wrong here
Segmentation complements firewalls and monitoring, it does not replace them.
- ✓
Enhanced enforcement of granular access control policies between zones
Why this is correct
Segregating zones allows administrators to apply strict firewall rules between business units.
- ✗
Guaranteed prevention of all zero-day malware infections on endpoints
Why it's wrong here
Segmentation controls network spread; it does not stop endpoint malware execution.
- ✗
Automatic encryption of all data at rest without performance overhead
Why it's wrong here
Segmentation does not encrypt data at rest.
- ✓
Containment of security breaches and limitation of lateral movement
Why this is correct
Segmentation isolates compromised zones, preventing attackers from easily moving across the entire network.
