Question 1170
At East Student Center, a distribution policy blocks return traffic after a stateless ACL is attached to the wrong SVI direction. What should be examined to confirm the actual failure mechanism?
Explanation
Correct Answer
For East Student Center, the decisive mechanism is ACL direction and interface. Stateless ACL effectiveness depends on interface attachment direction and rule order. Inspect hit counters rule ordering and packet direction for a controlled flow is the most direct way to isolate this particular failure before making a change.
Incorrect Answers
This is relevant to Access VLAN classification, where an access port carries untagged frames in one configured access VLAN In the East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is stateless ACL effectiveness depends on interface attachment direction and rule order
This is relevant to Tagged trunk allowlist, where a VLAN trunk forwards only permitted tagged VLANs and its native VLAN according to configuration In the East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is stateless ACL effectiveness depends on interface attachment direction and rule order
This is relevant to Native VLAN mismatch, where a native VLAN defines forwarding for untagged frames on a VLAN-aware trunk In the East Student Center case, Those observations could be normal while the stated fault persists. The specific mechanism is stateless ACL effectiveness depends on interface attachment direction and rule order
