Demo Questions
Question 1
On the MSTP network as shown in the figure, what is the role of the switch in MSTI 1 according to the configuration?
- Root switch
- Slave switch
- Non-root switch
- None of the above
Correct answer: A
Explanation:
appropriate. appropriate.
Question 2
As shown in the figure, which switch is the root switch according to the configuration?
- SWA
- SWB
- SWC
- None of the above
Correct answer: A
Question 3
On the RSTP network as shown in the figure, what RSTP operations will occur after the E1 port of SWB fails? (Select 3 Answers)
- SWB deletes the MAC address entries with the E1 port as the destination interface.
- The spanning tree is recalculated and the E2 port is elected as the new root port.
- All the interfaces in forwarding state send topology change notifications (TCNs) to notify other switches of the topology change.
- All the non-edge ports in forwarding state send TCNs to notify other switches of the topology change.
Correct answer: ABD
Question 4
Which is the port state defined in RSTP?
- Discarding
- Learning
- Forwarding
- All of the above
Correct answer: D
Question 5
RSTP has all functions that STP has and it is backward compatible with STP.
- True
- False
Correct answer: A
Question 6
RSTP adopts fast convergence mechanism. So, there is no Forward Delay interval in RSTP.
- True
- False
Correct answer: B
Explanation:
Question 7
Two switches are directly connected to each other and they are working in full duplex mode. By default, RSTP will consider the link between the switches as point-to-point link.
- True
- False
Correct answer: A
Explanation:
sophisticated. sophisticated.
Question 8
In RSTP network environment, a port can be set as edge port when it is directly connected with terminal.
- True
- False
Correct answer: A
Question 9
Which of the following statements about RSTP and STP is true?
- STP has more port states than RSTP.
- The port roles used in RSTP is less than the port roles used in STP.
- Since RSTP adopts fast convergence mechanism, it does not have Learning state which is available in STP.
- Same as STP, the ports will enter into Listening state once the RSTP has been enabled. Then, the ports can receive BPDU and calculate the spanning tree.
Correct answer: A
Explanation:
Question 10
In a switching network that runs RSTP, the topology change notification message will not be sent when the switch detects that the Alternate Port is failed.
- True
- False
Correct answer: A
Explanation:
authentic answer. authentic answer.
