Which of the following statements about pruning are correct? Select three answers. VTP pruning removes VLANs from the VLAN database of the local switch when no local ports are a part of that VLAN VTP pruning should only be enabled in client/server environments VTP pruning decreases the efficiency of trunks VTP pruning should can be enabled in any environment VTP pruning removes VLANs from the VLAN database of all switches when no local ports are a part of that VLAN VTP pruning increases the efficiency of trunks Question 5 of 16 6. Which of the following would most likely not cause intra-VLAN connectivity issues? Select the best answer. Configuration Issues Resource Oversubscription FHRP Misconfigurations Duplex Mismatches Bad NIC or Cable Question 6 of 16 7. Which of the following are valid reasons why a switch may be unable to update its local VLAN database? Select two answers. It receives packets with the same configuration revision number but a different MD5 hash value The switch has been configured as a VTP server Mismatched VTP password There are no reasons why a switch should be unable to update its local VLAN database VTP is disabled on the switch Question 7 of 16 8. Which of the following would NOT be a valid design consideration when designing the STP network? Select the best answer. Standardize using IEEE 802.1t Avoid End-to-End VLAN Solutions Design a Deterministic Topology Integrate Layer 3 Switching Determine the Location of the Root Bridge Question 8 of 16 9. Duplex mismatches are a common reason for Layer 2 (STP) loops? False True Question 9 of 16 10. Which of the following could cause a bridging (STP) loop in the network? Select three answers. Disabling etherchannel guard Switch resource utilization issues Physical layer connectivity issues Increasing STP timers on all switches in the network Implementing root guard Hardware or software errors Question 10 of 16 11. Which of the following is TRUE in regards to STP timers during periods of extended instability? Select the best answer. During periods of extended instability, increase the Hello Age and Fwd Delay timers During periods of extended instability, increase the Hello Age and Max Age timers During periods of extended instability, increase the Max Age and Fwd Delay timers During periods of extended instability, decrease the Hello Age and Max Age timers During periods of extended instability, decrease the Max Age and Fwd Delay timers During periods of extended instability, decrease the Hello Age and Fwd Delay timers Question 11 of 16 12. The show interfaces command can be used on both routers and switches. When used on routers, which of the following is NOT included in the output of this command? Select the best answer. The administrative status The media type The operational state The input and output packets The input and output errors The input and output queue drops The buffer failures and port errors Question 12 of 16 13. Which of the following queues counts Selective Packet Discard (SPD) drops on the Catalyst 6000 series switches? Select the best answer. None of these answers apply The output queue The input drops The input queue The output drops Question 13 of 16 14. While STP prevents loops in switched network, it does make some assumptions about the topology. What assumptions does STP make? Select two answers. All links are bidirectional The switch is able to regularly receive, process and send BPDUs All links are unidirectional The switch is unable to regularly receive, process and send BPDUs STP does make assumption; however, none of these options are correct STP makes no assumptions about the topology Question 14 of 16 15. Which of the following is TRUE in regards to VTP messages? Select three answers. VTP subset advertisements are sent out by servers every 5 minutes, by default VTP subset advertisements are sent out by VTP servers when VLAN configuration changes VTP summary advertisements are sent out by servers every 5 minutes, by default VTP summary advertisements are sent out by VTP servers when VLAN configuration changes VTP summary advertisements are requests for configuration information VTP advertisement requests are requests for configuration information Question 15 of 16 16. Which of the following statements about STP port priority is TRUE? Select the best answer. The valid port priority range is from 0 through 240 and the Cisco IOS default value is 128 The valid port priority range is from 0 through 255 and the Cisco IOS default value is 128 The valid port priority range is from 0 through 65,535 and the Cisco IOS default value is 10 The valid port priority range is from 0 through 65,535 and the Cisco IOS default value is 128 The valid port priority range is from 0 through 255 and the Cisco IOS default value is 10 The valid port priority range is from 0 through 240 and the Cisco IOS default value is 10 Question 16 of 16 Loading…
