Refer to the exhibit. Why has this switch not been elected the root bridge for VLAN1?




A.      It has more than one interface that is connected to the root network segment.

B.      It is running RSTP while the elected root bridge is running 802.1d spanning tree.

C.      It has a higher MAC address than the elected root bridge.

D.      It has a higher bridge ID than the elected root bridge.


Correct Answer: D




Refer to the exhibit. Which switch provides the spanning-tree designated port role for the network segment that services the printers?

B.      Switch2

C.      Switch3

D.      Switch4


Correct Answer: C




Refer to the exhibit. At the end of an RSTP election process, which access layer switch port will assume the discarding role?



A.      Switch3, port fa0/1

B.      Switch3, port fa0/12

C.      Switch4, port fa0/11

D.      Switch4, port fa0/2

F.       Switch3, port Gi0/2


Correct Answer: C




Refer to the exhibit. Given the output shown from this Cisco Catalyst 2950, what is the reason that interface FastEthernet 0/10 is not the root port for VLAN 2?




A.      This switch has more than one interface connected to the root network segment in VLAN 2.

B.      This switch is running RSTP while the elected designated switch is running 802.1d Spanning Tree.

C.      This switch interface has a higher path cost to the root bridge than another in the topology.

D.      This switch has a lower bridge ID for VLAN 2 than the elected designated switch.


Correct Answer: C




Which two of these statements regarding RSTP are correct? (Choose two.)


A.      RSTP cannot operate with PVST+.

B.      RSTP defines new port roles.

C.      RSTP defines no new port states.

D.      RSTP is a proprietary implementation of IEEE 802.1D STP.

E.       RSTP is compatible with the original IEEE 802.1D STP.


Correct Answer: BE



Refer to the exhibit. Each of these four switches has been configured with a hostname, as well as being configured to run RSTP. No other configuration changes have been made. Which three of these show the correct RSTP port roles for the indicated switches and interfaces? (Choose three.)




A.      SwitchA, Fa0/2, designated

B.      SwitchA, Fa0/1, root

C.      SwitchB, Gi0/2, root

D.      SwitchB, Gi0/1, designated

E.       SwitchC, Fa0/2, root

F.       SwitchD, Gi0/2, root


Correct Answer: ABF




Which port state is introduced by Rapid-PVST?


A.      learning

B.      listening

Correct Answer: C




Which two states are the port states when RSTP has converged? (Choose two.)


A.      discarding

B.      listening

C.      learning

D.      forwarding

E.       disabled


Correct Answer: AD




Which three statements about RSTP are true? (Choose three.)


A.      RSTP significantly reduces topology reconverging time after a link failure.

B.      RSTP expands the STP port roles by adding the alternate and backup roles.

C.      RSTP port states are blocking, discarding, learning, or forwarding.

D.      RSTP provides a faster transition to the forwarding state on point-to-point links than STP does.

E.       RSTP also uses the STP proposal-agreement sequence.

F.       RSTP uses the same timer-based process as STP on point-to-point links.


Correct Answer: ABD




At which layer of the OSI model is RSTP used to prevent loops?


A.      physical
