Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Use separate firewall interfaces for inside, outside, and DMZ
DMZ should have its own interface with a security level between inside and outside. Traffic from outside to DMZ should be restricted to necessary services. Inside to DMZ traffic should be permitted for management but initiated from inside.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
Use separate firewall interfaces for inside, outside, and DMZ
Why this is correct
Segmentation requires separate interfaces/zones.
- ✓
DMZ servers should not initiate connections to the inside network
Why this is correct
DMZ should be isolated; inside initiates if needed.
- ✗
DMZ interface should have a security level of 100
Why it's wrong here
100 is for inside; DMZ typically uses an intermediate level like 50.
- ✓
Restrict inbound traffic from outside to DMZ to only required services
Why this is correct
Minimize attack surface.
- ✗
Allow all traffic from inside to DMZ without inspection
Why it's wrong here
Traffic should be inspected and restricted.
