What is a potential risk of enabling BPDU filter on a port?

It can cause a switching loop if a switch is connected to the port

It will prevent the port from forwarding traffic

It will shut down the port if a BPDU is received

It will increase the convergence time

A network has two switches, SW1 and SW2, connected by two links. SW1 has bridge priority 4096, SW2 has 32768. Both switches have the same path cost to the root. Which port on SW2 will be in the discarding state?

The port on SW2 that connects to SW1 via the link that is not the root port.

Both ports on SW2 will be in discarding state.

Both ports on SW1 will be in discarding state.

The port on SW1 that connects to SW2 via the link that is not the root port.

A network engineer is troubleshooting a spanning-tree loop that occurs intermittently. The loop happens when a unidirectional link failure causes BPDUs to stop arriving on a root port. Which feature should be enabled to prevent the port from transitioning to forwarding when BPDUs are lost?

A network engineer is troubleshooting a spanning-tree loop that occurs only when a particular link becomes unidirectional. The link is a root port on one switch and a designated port on the other. The engineer suspects that BPDUs are not being received on the root port. Which feature should be enabled to prevent this loop?
