Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Implement a DMZ
Why this is correct
A DMZ is specifically designed to host public-facing services with controlled access.
- ✗
Place the server on the internal LAN with a strong firewall rule
Why it's wrong here
This still exposes the internal network if the server is compromised.
- ✗
Use a VLAN to logically separate the server
Why it's wrong here
A VLAN alone does not provide the same security as a DMZ; it still shares the same infrastructure.
- ✗
Connect the server directly to the internet without firewall
Why it's wrong here
That would expose the server to all threats.
