Question

Quizplus · Accepted Answer

The protocol that must be running on the switches is the Spanning Tree Protocol (STP), which is used to prevent loops and ensure redundancy in a network. One of the connections being in blocking mode indicates that STP has determined the best path for data to flow without causing a loop. RIP, SNMP, and NTP are all different protocols that serve different purposes and are not relevant to the given scenario.
