Given the following fields, which of those cannot be compared on an extended IP ACL?

(A) Application protocol
(B) Destination IP address
(C) Source IP address
(D) URL
(E) TOS Byte

URL cannot be compared on an extended IP ACL.

Extended ACLs can’t look at the URL as this is an Application Layer information. Extended ACLs can look at Layer 3 (IP) and Layer 4 (TCP, UDP) headers.
