Which access controls list allows only TCP traffic with a destination port range of 22-433, excluding port 80?
A . Deny tcp any any eq 80
Permit tcp any any gt 21 it 444
B . Permit tcp any any ne 80
C . Permit tcp any any range 22 443
Deny tcp any any eq 80
D . Deny tcp any any ne 80
Permit tcp any any range 22 443
Answer: C
Explanation:
Although the statement “permit tcp any any gt … lt …” seems to be correct but in fact it is not.
Each ACL statement only supports either “gt” or “lt” but not both:
In fact answer ‘Permit tcp any any range 22 443
Deny tcp any any eq 80
eq80.
