Module 11 Exam Back to Main Page 1. STP was originally created by Radia Perlman and was later standardized by IEEE _____.802.1C802.1E802.1D802.1B802.1AQuestion 1 of 25 2. Each switch usually assumes it is the spanning tree root until the BPDUs have all been exchanged between the switches.TrueFalseQuestion 2 of 25 3. The default bridge priority of a Cisco switch is ______.32768409610242048Question 3 of 25 4. All switches in the network take part in an election to decide the root of the spanning tree; this then leads to them making further decisions, such as which redundant path to block and which to open. The election is won by the switch with the highest BID.TrueFalseQuestion 4 of 25 5. The STP root bridge will only ever have one root port.TrueFalseQuestion 5 of 25 6. Match the STP cost of the ports with the port speed.16 Mbps 19Unselect2Unselect62Unselect100Unselect4Unselect1 Gbps 19Unselect2Unselect62Unselect100Unselect4Unselect10 Gbps 19Unselect2Unselect62Unselect100Unselect4Unselect100 Mbps 19Unselect2Unselect62Unselect100Unselect4Unselect10 Mbps 19Unselect2Unselect62Unselect100Unselect4UnselectQuestion 6 of 25 7.

The 802.1T standard introduced an extended system ID in order to conserve MAC addresses while still allowing for a unique BID. With extended system ID enabled (VLAN 10 in this example), the bridge priority is set to either ____ as a minimum or a multiple of ____.4096032768256Question 9 of 25 10. STP elections take place using the following order: Lowest root path cost to the root bridge Lowest sender bridge ID Lowest root bridge ID Lowest sender port ID Question 10 of 25 11. The primary factor in deciding the STP root bridge is the ______ and in deciding the root ports on the non-root bridges is the _____, which is cumulative.root bridge ID, path costport cost, path costinterface ID, port costVLAN ID, bridge IDQuestion 11 of 25 12. Assuming no extra configurations, which switch will become root bridge? ABCDNone of themQuestion 12 of 25 13.

PortFast is typically enabled on an interface connected directly to a switch.TrueFalseQuestion 14 of 25 15. STP is disabled on a port using PortFast.TrueFalseQuestion 15 of 25 16. Th e command to configure PortFast is _________.spanning-tree portfastportfast spanning-treespan portport spanQuestion 16 of 25 17. A colleague calls you to ask how she can check if uplinkfast has been configured on the switch. What do you tell her to type?show spanning-tree allshow uplinkfastshow spanning-tree uplinkfastshow stp status uplinkfastQuestion 17 of 25 18. ______ works by finding an alternate path when an indirect link to the root port goes down.BackboneFastUplinkfastPortfastRSTP+PVSTP+Question 18 of 25 19. BackboneFast only need to be enabled on one master switch in order for this feature to work.TrueFalseQuestion 19 of 25 20. With this feature configured, if a BPDU is received on a switch port, it will be put into an err-disabled mode and an administrator will have to bring up the port.BPDU GuardPortfastUplinkfastBackbonefastQuestion 20 of 25 21. When _____ is configured on a switch port that has been configured as PortFast, it will prevent the port from sending and receiving BPDUs on that port.BPDU FilterPortfastBPDU GuardRSTP+RootguardQuestion 21 of 25 22. Root Guard is designed to ensure that the port becomes a root port.TrueFalseQuestion 22 of 25 23. What are the three RSTP link types?Point-to-pointSharedEdgeMasterSlaveBackupQuestion 23 of 25 24. RSTP has defined which two new port roles?AlternateBackupMasterDesignatedSlaveAutoQuestion 24 of 25 25.
