Which mechanism ensures that the traffic inside the network follows an optimized path to enhance network performance?

• A. STP
• B. VLAN hopping
• C. ICMP Router Discovery Protocol (IRDP)
• D. XArp

Answer: (A)

Optimizing traffic inside a switched network comes from creating a loop-free topology that selects a single best path to every destination. Spanning Tree Protocol accomplishes this by electing a root switch and calculating the shortest path to it for all switches, then putting some redundant switch ports into a blocking state. This leaves just one active path to each segment, preventing loops that can cause broadcast storms and wasted bandwidth, while still keeping alternative links ready to use if a failure occurs. The result is a stable, efficient network where traffic follows the most suitable path through the tree. The other options don't provide this mechanism: VLAN hopping targets bypassing VLAN boundaries, IRDP is used for discovering routers on a network and doesn't optimize internal paths, and XArp is an ARP discovery/poisoning tool, not a path optimization protocol.
