A customer network engineer has made configuration changes that have resulted in some loss of
connectivity. You have been called in to evaluate a switch network and suggest resolutions to the
problems.
Which of statement is true regarding STP issue identified with switches in the given topology?
A.
Loopguard configured on the New_Switch places the ports in loop inconsistent state
B.
Rootguard configured on SW1 places the ports in root inconsistent state
C.
Bpduguard configured on the New_Switch places the access ports in error-disable
D.
Rootguard configured on SW2 places the ports in root inconsistent state
Explanation:
On the new switch, we see that loopguard has been configured with the “spanning-tree guard
loop” command.The loop guard feature makes additional checks. If BPDUs are not received on a non-designated
port, and loop guard is enabled, that port is moved into the STP loop-inconsistent blocking state,
instead of the listening / learning / forwarding state. Without the loop guard feature, the portassumes the designated port role. The port moves to the STP forwarding state and creates a loop.
