QUESTION 1
How are STP timers and state transitions affected when a topology change occurs in an STP environment?

A.All ports will temporarily transition to the learning state for a period equal to the max age timer
plus the forward delay interval.
B.All ports will transition temporarily to the learning state for a period equal to the forward delay interval.
C.The default aging time for MAC address entries will be reduced for a period of the max age timer
plus the forward delay interval.
D.The default hello time for configuration BPDUs will be reduced for the period of the max age timer.

Answer: C

QUESTION 2
What two things will occur when an edge port receives a BPDU? (Choose two.)

A.The port immediately transitions to the Forwarding state.
B.The switch generates a Topology Change Notification (TCN) BPDU.
C.The port immediately transitions to the err-disable state.
D.The port becomes a normal STP switch port.

Answer: BD

QUESTION 3
What will occur when a nonedge switch port that is configured for Rapid Spanning Tree does not receive a BPDU from its neighbor for three consecutive hello time intervals?

A.RSTP information is automatically aged out.
B.The port sends a TCN to the root bridge.
C.The port moves to listening state.
D.The port becomes a normal spanning tree port.

Answer: A

QUESTION 4
Which option correctly identifies the Cisco IOS switching methods in descending order from the fastest method to the slowest method?

A.CEF, distributed CEF (dCEF), fast switching, process switching
B.distributed CEF (dCEF), CEF, fast switching, process switching
C.fast switching, process switching, distributed CEF (dCEF), CEF
D.process switching, fast switching, distributed CEF (dCEF), CEF
E.process switching, distributed CEF (dCEF), CEF, fast switching
F.process switching, CEF, distributed CEF (dCEF), fast switching

Answer: B

QUESTION 5
Which three statements about STP timers are true? (Choose three.)

A.STP timers values (hello, forward delay, max age) are included in each BPDU.
B.A switch is not concerned about its local configuration of the STP timers values. It will only
consider the value of the STP timers contained in the BPDU it is receiving.
C.To successfully exchange BPDUs between two switches, their STP timers value (hello, forward
delay, max age) must be the same.
D.If any STP timer value (hello, forward delay, max age) needs to be changed, it should at least be
changed on the root bridge and backup root bridge.
E.On a switched network with a small network diameter, the STP hello timer can be tuned to a lower
value to decrease the load on the switch CPU.
F.The root bridge passes the timer information in BPDUs to all routers in the Layer 3 configuration.
