Refer to the exhibit. Topology view - You just connected three FortiSwitch devices: Core-1, Core-2, and Access-1. Core-1 and Core-2 both connect to Access-1 for redundancy. All switches are managed by FortiGate, which uses port4 as the FortiLink interface. After you enable the uplink ports on Core-2, you notice that port3 on Access-1 enters the Discarding STP state. What is the most likely cause of this behavior?

1. A. Bridge Protocol Data Unit (BPDU) Guard is enabled, which shuts down the port after it receives BPDUs.
2. B. Access-1 is not authorized by FortiGate.
3. C. Core-2 has the lowest bridge priority.
4. D. FortiGate is not running Spanning Tree Protocol (STP) on the FortiLink interface. — đáp án hiện tại
