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
✓
permit ip any any
After explicitly denying the specific subnet, you must permit the rest of the traffic with 'permit ip any any'.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
deny ip any 10.1.1.0 0.0.0.255
Why it's wrong here
This is the first line, not the last line.
- ✗
permit tcp any any
Why it's wrong here
This is too narrow; it must be 'ip' to cover all protocols.
- ✓
permit ip any any
Why this is correct
Standard ACL logic requires an explicit permit for the remaining traffic.
- ✗
deny ip any any
Why it's wrong here
This would block all traffic after the deny statement.
