Refer to the exhibit. An engineer is deploying a Cisco ACI fabric with an L2Out to external switches. The Cisco ACI fabric has just been deployed and follows the default forwarding behavior. Which…

Adding ports Eth1/1 and Eth1/2 to an LACP port channel bundles these physical links into a single logical link, eliminating Layer 2 loops while providing redundancy and increased bandwidth to the external switch.

Enabling MCP (Multi-Chassis Port Channel) is generally for managing multi-chassis link aggregation groups and is not typically used for direct loop prevention between single leaf switches and external devices in an L2Out.

Disconnecting the link between Leaf3 and Leaf4 directly removes a potential Layer 2 loop path if both leafs are connected to the same external switch and participating in the same L2Out.

Implementing LLDP on ports is a discovery protocol and does not directly prevent Layer 2 forwarding loops; it only helps identify connected devices.

Configuring BPDU guard on Catalyst switch ports is a reactive measure to disable a port upon receiving a BPDU, preventing a rogue loop, but it does not proactively design a loop-free topology.
