Which two methods could eliminate the need for spanning tree in a two switch network?

In a two-switch network, minimizing or eliminating the need for spanning tree can be achieved through specific network configurations that prevent loops and ensure efficient traffic flow. The option of having no Layer 2 parallel paths directly addresses the potential for loops that spanning tree is designed to prevent. By ensuring there are no redundant paths at Layer 2, the topology remains simple and loop-free, which eliminates the necessity for spanning tree protocols to manage redundant links.

In a network topology where there are no parallel paths between switches, the data follows a single, clear path, reducing the chances of broadcast storms or switching loops that could degrade network performance. This leads to a more efficient, predictable network operation without the overhead that spanning tree introduces for loop detection and blocking.

While utilizing multiple VLANs or EtherChannel can provide other benefits to the network, they do not inherently remove spanning tree requirements unless they are specifically implemented in a way that also ensures there are no Layer 2 loops. The reduction of broadcast domains is related to managing traffic but does not directly address loop prevention. Therefore, the focus on no Layer 2 parallel paths is the key factor in eliminating the need for spanning tree in a simple two-switch configuration.
