Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
An ACL applied to the DMZ interface permitting traffic to inside.
Why this is correct
Correct; ACL on DMZ (lower level) permits traffic to inside (higher level).
- ✗
A NAT rule is required.
Why it's wrong here
NAT is not required for traffic between DMZ and inside.
- ✗
An ACL applied to the inside interface permitting traffic from DMZ.
Why it's wrong here
ACLs on the higher security interface are for outbound traffic; for inbound from lower to higher, ACL on the lower interface is needed.
- ✗
No additional configuration; it is allowed by default.
Why it's wrong here
Lower to higher traffic is blocked by default.
