Question 1062

At East Student Center, a distribution policy blocks return traffic after a stateless ACL is attached to the wrong SVI direction. What safety boundary prevents the same campus failure in future deployments?

  1. Never expand a trunk to all VLANs merely to resolve one missing segment.
  2. Document native VLAN consistently and keep sensitive VLANs tagged.
  3. Stage ACL changes with console rollback to avoid management lockout.
  4. Deny unapproved client VLAN changes and review port moves before deployment.

Explanation

Correct Answer
