The designated distribution root reappears and traffic follows the planned loop-free topology. Such an observation would verify a separate issue: An unapproved access switch becomes MSTP root and shifts traffic through a low-capacity closet. It would follow the distinct action: Restore intended bridge priorities and MSTP region settings under controlled change. Here the reported failure is A recently added ACL denies a permitted monitoring flow to the management SVI. The decisive result for Fairmont Logistics must instead be: Approved monitoring succeeds while unauthorized management requests remain blocked.

Rogue offers are discarded while leases from the legitimate server still succeed. Such an observation would verify a separate issue: A rogue DHCP server sends offers from an edge port after a security change accidentally marks that port trusted. It would follow the distinct action: Correct DHCP snooping trust on the untrusted edge and keep only validated server paths trusted. Here the reported failure is A recently added ACL denies a permitted monitoring flow to the management SVI. The decisive result for Fairmont Logistics must instead be: Approved monitoring succeeds while unauthorized management requests remain blocked.

A routed client completes DHCP lease acquisition and the relay forwards responses correctly. Such an observation would verify a separate issue: A client gateway forwards traffic but DHCP clients across a routed VLAN receive no offer from a remote server. It would follow the distinct action: Validate and correct DHCP relay/helper configuration and L3 reachability to the authorized server. Here the reported failure is A recently added ACL denies a permitted monitoring flow to the management SVI. The decisive result for Fairmont Logistics must instead be: Approved monitoring succeeds while unauthorized management requests remain blocked.
