An administrator configures VLANs to separate a web-tier from a database-tier. After applying these settings to trunk ports, traffic between the tiers stops, and logs indicate a mismatch on the trunk. Which action is the most effective step to restore communication between the servers?
Enable loop prevention features on the switches using spanning tree
Change all switch ports to operate in trunk mode
Reassign switch interfaces to the appropriate IDs in the VLAN definitions
Add static routes on the router for the new network segments
Ensuring VLAN assignments match their definitions is vital for data flow. Reassigning the correct IDs synchronizes the trunk ports with connected devices. Spanning tree protocol addresses loop prevention but does not resolve the VLAN assignment issue. Changing all ports to trunk mode introduces unnecessary complexity. Adding static routes does not fix mismatches in the switch configuration, which stops traffic at the VLAN layer before routes are even used.
