more specific entries?
A. in the middle of the access control list?
B. higher in the access control list
C. lower in the access control list
D. at the bottom of the access control list
Answer: B

Place more specific access list statements higher in the access list. Ensure statements at
the top of the access list do not negate any statements found lower in the list.

statements found lower in the list.
