1
256
2048
4096
True or false: The advertised path cost includes the advertising link’s port cost as part of the configuration BPDU advertisement.
True
False
True or false: The switch port with the lower STP port priority is more preferred.
True
False
What happens to a switch port when a BPDU is received on it when BPDU guard is enabled on that port?
A message syslog is generated, and the BPDU is filtered.
A syslog message is not generated, and the BPDU is filtered.
A syslog message is generated, and the port is sent back to a listening state.
A syslog message is generated, and the port is shut down.
Enabling root guard on a switch port does what?
Upon receipt of an inferior BPDU, the port is shut down.
Upon receipt of a superior BPDU, the port is shut down.
Upon receipt of an inferior BPDU, the BPDU is filtered.
When the root port is shut down, only authorized designated ports can become root ports.
UDLD solves the problem of ______.
time for Layer 2 convergence
a cable sending traffic in only one direction
corrupt BPDU packets
flapping network links

BPDU propagation
Synchronization
Forward timer expiration
BPDU
What causes RSTP to view a port as a point-to-point port?
Port speed
Port media
Port duplex
Port priority
Which of the following events triggers a topology change with RSTP on a nonedge port?
