Question 1090
At East Student Center, a distribution policy blocks return traffic after a stateless ACL is attached to the wrong SVI direction. How should the engineer validate success against the stated requirement?
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. Permit a specifically authorized app and block the matching forbidden traffic supplies measurable, case-relevant evidence that the intended behavior actually occurs.
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, That test could pass while the actual user-facing requirement still fails. 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, That test could pass while the actual user-facing requirement still fails. 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, That test could pass while the actual user-facing requirement still fails. The specific mechanism is stateless ACL effectiveness depends on interface attachment direction and rule order
