Question 24 Discussion

Refer to the exhibit. 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? (Choose one answer)

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

Selected Answers: C


C is absolutely correct. The other options don't explain the beaviour correctly. When you bring up Core-2’s uplinks it likely became the STP root (lowest priority). STP then blocks (puts in Discarding) one of the Access-1 uplinks to prevent a loop.
