Question 320
At the Southridge banking office, an IPv4 ACL on R-SRG-EDGE1 allows two explicit applications, but an otherwise legitimate management source loses connectivity after the ACL is applied. Which underlying technical condition best accounts for this evidence?
Explanation
Correct Answer
The evidence at the Southridge banking office supports this condition: Packets that do not match an ACL permit statement are denied by the implicit final rule. The associated fix is: Add a narrowly scoped permit for the authorized source and service above the implicit deny.
Incorrect Answers
That diagnosis belongs to urpf loose versus strict source check, while the observation at the Southridge banking office points to ipv4 acl implicit deny.

That diagnosis belongs to ipv4 wildcard mask matching, while the observation at the Southridge banking office points to ipv4 acl implicit deny.
