What configuration is most likely needed to ensure no Layer 2 loops in a network with two switches?

Implementing Spanning Tree Protocol (STP) is crucial for ensuring that there are no Layer 2 loops in a network, especially in environments where redundancy is desirable, such as those with multiple switches. STP works by creating a loop-free logical topology for Ethernet networks, which is essential when multiple switches are connected together.

When STP is enabled, it identifies and disables redundant paths in the network. It does this by selecting a root switch and determining the best path to it, blocking any other paths that could cause a loop. This helps maintain a stable Ethernet network and prevents broadcast storms and other issues that arise from loops.

The other options do not effectively address the issue of Layer 2 loops. Disabling STP, for example, increases the risk of loops, while using SSH for management does not relate to network topology management. Configuring static MAC addresses does not provide a solution for loop prevention either, as it merely affects how devices are identified on the network without managing the paths that data takes. Therefore, the implementation of Spanning Tree Protocol is the most logical and effective configuration to prevent Layer 2 loops in a multi-switch environment.
