Question 50/142
If Spanning Tree Protocol (STP) is disabled on the network consisting of switches, a Layer 2 loop will definitely occur.
Correct Answer: A
Disabling STP on a network with redundant paths between switches leads to a Layer 2 loop, which can cause broadcast storms and network congestion. STP is essential for preventing such loops by blocking redundant paths until needed for redundancy, ensuring network stability.
