Exam N10-008 topic 1 question 268 discussion

STP is used to prevent looping on layer 2 networks that would have otherwise caused broadcast storms to occur. Any ring topology network will be create intersecting circuits. The basic function of STP is to prevent bridge loops and the broadcast radiation that results from sending signals back from where the signal originally came from. If you have redundant links set up, it is important to utilize STP to prevent loops within the network. If a loop occurs, the performance of the entire network can be degraded due to broadcast storms.

layer 2, the others dont work on layer , and port mirroring is just copying data

STP is enabled by defaulttttttttttttttttttttttttttttttttttttttt

In a network with redundant paths (which are common for fault tolerance and redundancy purposes), STP determines which paths should be active and which should be in a blocking state to prevent loops. If a link or switch fails, STP recalculates the topology to activate a previously blocked path, thus maintaining network connectivity even in the presence of failures. Open Shortest Path First (B) and An interior gateway protocol (D) are routing protocols used in Layer 3 networks, and they are not typically used to create fault-tolerant rings in Layer 2 networks. Port mirroring (C) is used for network monitoring and analysis, not for creating fault-tolerant rings.

A. Spanning Tree Protocol (STP) is the correct answer. Spanning Tree Protocol (STP) is a network protocol that ensures a loop-free topology in Ethernet networks by actively blocking certain links and enabling others. STP prevents loops by putting some of the links in a blocking state, effectively creating a loop-free topology. This ensures that there is only one active path between two devices, which helps prevent network loops and the associated problems (such as broadcast storms) that can result from them. STP is used to create a fault-tolerant ring between three switches within a Layer 2 network.

Spanning Tree Protocol (STP) is a Layer 2 network protocol used to prevent looping within a network topology. STP was created to avoid the problems that arise when computers exchange data on a local area network (LAN) that contains redundant paths.
