In a small company's local network, an IT technician suspects that there might be a Layer 2 loop occurring due to improper switch configuration. Which feature should be enabled on the company's network switches to prevent broadcasting loops and ensure efficient handling of network frames?
The correct answer is Spanning Tree Protocol (STP). STP is crucial for preventing loops in a network by detecting and disabling redundant paths, ensuring a loop-free topology. Whenever STP senses a loop, it blocks redundant links and only allows necessary paths to be active to prevent broadcast storms and possible data collisions. Port Mirroring, RSTP, and Quality of Service (QoS) are false traps. Port Mirroring is used for monitoring and not for loop prevention, whereas QoS prioritizes traffic and also isn't used to avoid loops. Loop Detection and Prevention Protocol (LDPD) is a term we made up and is not a real protocol.
