BPDU Guard should be enabled on all ports with Port Fast enabled.FalseTrueQuestion 4 of 29 5. Port Fast is a feature that is typically enabled only for a port or interface that connects to a switch.FalseTrueQuestion 5 of 29 6. All your switches are left at default settings. Which of the below commands will set your switch to be the STP root?Switch(config)#spanning-tree vlan 2 root 4096Switch(config)#spanning-tree vlan 2 root Switch(config)#spanning-tree vlan 2 root primarySwitch(config)#spanning-tree vlan 2 root activeQuestion 6 of 29 7. BPDUs are sent every ___ seconds.102201Question 7 of 29 8. The Root Guard feature prevents a Root Port from becoming a Designated Port.TrueFalseQuestion 8 of 29 9. The BPDU Guard feature prevents the port from receiving any BPDUs but does not prevent it from sending them. If any BPDUs are received, the port will be errdisabled.FalseTrueQuestion 9 of 29 10. RSTP port roles include (choose all that apply)DesignatedBackupRootAlternateQuestion 10 of 29 11. The Uplink Fast feature provides faster failover to a redundant link when the indirect link fails.TrueFalseQuestion 11 of 29 12. All your switches are left at default settings. Which of the below commands will set your switch to be the STP root?Switch(config)#spanning-tree vlan 2 priority primarySwitch(config)#spanning-tree vlan 2 priority 32768Switch(config)#spanning-tree vlan 2 priority 65535Switch(config)#spanning-tree vlan 2 priority 4096Question 12 of 29 13. Per VLAN Spanning Tree Plus (PVST+) allows for an individual STP instance per VLAN.FalseTrueQuestion 13 of 29 14.

In the spanning tree learning state the switch discards frames received from the attached segment.TrueFalseQuestion 15 of 29 16. Switches determine the best Configuration BPDU based on the following four factors which order?: Lowest Root Bridge ID Lowest Root path cost to Root Bridge Lowest sender Bridge ID Lowest sender Port ID1324432121341234Question 16 of 29 17. The default port cost for Fast Ethernet is?12501962Question 17 of 29 18. Which port is marked in the below diagram? Backup PortSecondary PortRedundant PortAlternate PortQuestion 18 of 29 19. RSTP performs similar functions to Uplink Fast and Backbone Fast.FalseTrueQuestion 19 of 29 20. In the spanning tree listening state the switch discards frames received on the port from the attached segment.TrueFalseQuestion 20 of 29 21. RSTP uses the same BPDU as STP.FalseTrueQuestion 21 of 29 22. What type of port is obscured in the below fig? Backup PortRoot PortSecondary PortAlternate PortQuestion 22 of 29 23. STP port Listening state can be mapped to RSTP ____ state.ListeningLearningDiscardingForwardingQuestion 23 of 29 24. RSTP is backwards compatible with STP.TrueFalseQuestion 24 of 29 25. In the spanning tree forwarding state the switch _____ frames received from the attached segment.buffersdiscardsforwardsblocksQuestion 25 of 29 26. STP uses the exchange of BPDUs to determine the network topology, which is determined by the following three variables:The unique MAC address (switch identifier) that is associated with each switch The ARP cache entry for the connected switchThe port identifier (MAC address of the port) associated with each switch port The path cost to the Root Bridge associated with each switch port Question 26 of 29 27.
