Rapid Spanning Tree Protocol Data Communication Quiz by Ravinder Nath Rajotiya - November 14, 2019November 14, 20190 Share on Facebook Share Send email Mail Print Print Rapid Spanning Tree Protocol RSTP was introduced to overcome the limitations of the spanning tree protocol (STP). Advantage of STP: Though STP ensures a loop-free network. Problem with STP: With increased topology changes, STP slows down the network topology convergence speed, leading to service deterioration causing regular interruption. RSTP employs a proposal and agreement process which allows for immediate negotiation of links to take place, effectively removing the time taken for convergence based timers to expire before spanning tree convergence can occur. The proposal and agreement process tends to follow a cascading effect from the point of the root bridge through the switching network, as each downstream switch begins to learn of the true root bridge and the path via which the root bridge can be reached. RSTP Quiz Welcome to your RSTP Quiz 1. After an RSTP-enable switch receives the BPDUs with the TC bit set, the MAC addresses learned by all the ports are cleared TRUE FALSE None 2. What is the value of the type field in RSTP configuration BPDUs? 0X00 0X01 0X02 0X03 None 3. The loop protection function provided by RSTP can take effect only on designated port TRUE FALSE None 4. . Which of the following port roles are added to Rapid Spanning Tree Protocol (RSTP) compared with STP? Root port Designated port Alternate port Backup port None 5. Which of the following is not the reason why RSTP can increase the convergence speed? P/A mechanism Edge port Quick transition between root port state The Forward Delay timer is canceled None 6. Which of the following statements is true about the alternate port in RSTP? An Alternate port acts as a backup of the designated port and provides a backup path from the root bridge to the related network segment An Alternate port acts as a backup of the root port and provides a alternate path from the designated bridge to the root bridge An alternate port does not forward user traffic but learns MAC address An alternate port forward user traffic and learns MAC address None 7. The root protection function provided by RSTP can take effect only on designated ports TRUE FALSE None 8. In RSTP, a backup port can replace a faulty root port TRUE FALSE None 9. In RSTP, an edge port becomes a common STP port after receiving a Configuration BPDU. TRUE FALSE None 10. Which of the following bits are used in the Flag field in the RSTP configuration BPDU but not used in the Flag field in the STP TCA TC PROPOSAL AGREEMENT None 11. As define in RSTP to improve the convergence speed you can define the port that is directly connected to a terminal as the ( ) Fast port Backup port Root port Edge port None 12. Which of the following port states are included in Rapid Spanning Tree Protocol (RSTP)? Forwarding Learning Discarding Listening None Time's up Share on Facebook Share Send email Mail Print Print
