What is the expected outcome when two switches connected via EtherChannel with STP enabled are utilized?

• A. Both links will be utilized
• B. STP will block one of the redundant links
• C. STP will bridge all links
• D. STP will create a loop-free environment

Answer: (B)

When two switches are connected via EtherChannel with Spanning Tree Protocol (STP) enabled, the expected outcome is that STP will block one of the redundant links. EtherChannel allows multiple physical links to be bundled together to form a single logical link, which increases bandwidth and provides redundancy. However, STP's purpose is to prevent loops in the network. In a typical Ethernet network without EtherChannel, STP would block one path in a redundant link setup to eliminate loops. With EtherChannel, the logical bundle of links is treated as a single connection by STP. Even though the physical links may be operational, STP will still determine a single path to the root bridge and block one of the redundant links to maintain a loop-free environment. This means that even though the EtherChannel is not fully utilizing all its links for data traffic, it preserves network stability and optimizes traffic flow by avoiding loops.
