Which statement best describes STP? correct answers STP is a Layer 2 loop prevention
protocol for Ethernet LANS.
Without STP on the Ethernet LAN, which three types of frames could cause a catastrophic
loop in the network? (Choose three.) correct answers unknown unicast, multicast, broadcast
What device is elected by the Spanning Tree Algorithm to which all other switches determine
a single least-cost path? correct answers root bridge
By default (without any configuration on a switch), what will determine which switch is the
root bridge? correct answers the mac address on the switch
The root bridge will be the switch with the: correct answers lowest bridge id
The port closest to the root bridge in terms of least overall cost (best path) to the root bridge
is the: correct answers root port
The port on the segment (with two switches) that has the lowest path cost to the root bridge is
the: correct answers designated port
Which of the following ports will forward Ethernet frames? (Choose two.) correct answers
designated port, root port
The sum of individual port costs along the path from the switch to the root bridge is known as
the: correct answers root path cost
How often does a switch send a BPDU? correct answers every 2 seconds
Which three STP port states are merged into the RSTP discarding port state? (Choose three.)
correct answers disabled, blocking, listening
Which protocol was designed to bring faster convergence to STP? correct answers rstp
Which technology solves the problem of a device being unable to get an IPv4 address from a
DHCP server due to STP forwarding delay timers? correct answers portfast
What additional information is contained in the 12-bit extended system ID of a BPDU?
correct answers vlan id
During the implementation of Spanning Tree Protocol, all switches are rebooted by the
network administrator. What is the first step of the spanning-tree election process? correct
answers all the switches send out bpdus advertising themselves as the root bridge
Which STP port role is adopted by a switch port if there is no other port with a lower cost to
the root bridge? correct answers root port
