Switch Bonus Quiz 7 1. What assumptions does the Spanning Tree protocol make about the network? Select TWO answers. All switches can regularly receive, process, and send Bridge Protocol Data Units All links are bidirectional and can both send and receive Bridge Protocol Data Units There are no RSTP or MSTP switches in the network All switches in the network are Cisco Catalyst switches The administrator has already determined what the switched network topology should look like Per-VLAN Spanning Tree protocol will be enabled for all types of switches Question 1 of 22 2. The Message Age timer can be used to determine the following two variables. What are these variables? The time before the next BPDU is received The time since the non-Root Bridge originated the BPDU The time before the switch will send another BPDU The time before the received BPDU is aged out on the port The hop count from the Root Bridge Question 2 of 22 3. Which of the following statements is NOT true in regards to end-to-end VLANs? These VLANs allow for the mobility of end devices They are easy to implement and troubleshoot They support maximum flexibility Each VLAN provides common security and resource requirements for members They allow the grouping of users into a single VLAN independent of physical location Question 3 of 22 4. In the 802.1w standard, which of the following specifies the minimum time during which RSTP BPDUs are sent and the port mode is locked and cannot be changed?

What STP timer is modified by every switch that receives and propagates a BPDU? Migration Delay Timer Convergence Timer TC While Timer Hello Timer Message Age Timer Maximum (Max) Age Timer Question 5 of 22 6. What is the default 802.1t port cost for a GigabitEthernet port? 200000 125000 1250 2000 20000 12500 Question 6 of 22 7. When DAI is enabled, the switch performs which of the following activities? Select THREE answers. Logs invalid ARP packets Intercepts all inbound ARP requests and responses on untrusted ports Verifies that each of these intercepted packets has a valid IP-to-MAC address binding after updating the local ARP cache or after forwarding the packet to its destination Verifies that each of these intercepted packets has a valid IP-to-MAC address binding before updating the local ARP cache or before forwarding the packet to its destination Drops invalid ARP packets Intercepts all outbound ARP requests and responses on untrusted ports Question 7 of 22 8. Which of the following statements about Spanning Tree port priority are TRUE? Select THREE answers. The valid port priority range is from 0 through 256 With 802.1t, the port priority is 4 bits, which allows 12 bits to be used for the port number The valid port priority range is from 0 through 240 With 802.1t, the port priority is 6 bits, which allows 10 bits to be used for the port number The default port priority on all Cisco Catalyst switches is 128 The default port priority on all Cisco Catalyst switches is 127 Question 8 of 22 9. What type of algorithm is used to perform load balancing for EtherChannels? COX ROX AOR ZOR XOR Question 9 of 22 10. Assume that two switches, Switch 1 and Switch 2 are connected via an ISL trunk. The VLAN and VTP configuration on the switches is illustrated in the Exhibit. What effect will the configuration have on the switches? Select THREE answers. VLAN 20 will be shut down on Switch 1 and Switch 2 VLAN 20 will not be shut down on Switch 1 and Switch 2 VLAN 10 will be suspended on Switch 1 and Switch 2 VLAN 20 will be shut down on Switch 1 only VLAN 10 will be suspended on Switch 2 only VLAN 10 will not be suspended on Switch 2 only VLAN 10 will not be suspended on Switch 1 and Switch 2 VLAN 20 will not be shut down on Switch 1 only Question 10 of 22 11. When implementing the LACP 1:1 Redundancy with Fast-Switchover feature, who many ports should be placed into the EtherChannel? 1 4 8 2 16 Question 11 of 22 12. What happens when a switch in one VTP domain receives VTP packets from a switch in another VTP domain? The switch will reject the packets The switch will relay the VTP packets on The switch will shut down the port on which the VTP packets are received The switch will join the new VTP domain The switch will place the port into a VTP inconsistent (err-disabled) state Question 12 of 22 13. Which of the following statements about Spanning Tree port cost and port priority are FALSE? Select FOUR answers. The Spanning Tree port priority should be configured on the Root Bridge The Spanning Tree port priority should be configured on the non-Root Bridge The Spanning Tree port cost is locally significant between two switches The Spanning Tree port priority value is globally significant and affects the entire Spanning Tree network The Spanning Tree port cost should be configured on the non-Root Bridge The Spanning Tree port cost should be configured on the Root Bridge The Spanning Tree port cost value is globally significant and affects the entire Spanning Tree network The Spanning Tree port priority is locally significant between two switches Question 13 of 22 14. Inter-Switch Link (ISL) is a proprietary trunking protocol that is supported across all Cisco Catalyst platforms. False True Question 14 of 22 15. What happens when more than 8 compatible ports are placed into an LACP EtherChannel? Up to 4 ports are used and the remainder are placed into the Hot Standby state This is not permitted in Cisco IOS software; the EtherChannel will be err-disabled Up to 12 ports are used and the remainder are placed into the Hot Standby state Up to 16 ports are used and the remainder are placed into the Hot Standby state Up to 8 ports are used and the remainder are placed into the Hot Standby state Question 15 of 22 16. What is the default Spanning Tree diameter? 3 20 15 7 4 Question 16 of 22 17. Click on the Exhibit. Management has requested that you enable DAI on this switch. Which of the following configuration commands would you issue to configure the GigabitEthernet interfaces as UNTRUSTED? Use the ip arp inspection untrusted command Use the ip arp inspection untrusted vlan 5 command Use the ip arp inspection vlan 5 command Use the ip arp inspection untrust command Use the ip arp inspection vlan 5 untrusted command Question 17 of 22 18. Cisco Catalyst 6500 series switches support two types of CEF rate limiters. What are the names of these rate limiters? CEF Receive CEF Punt CEF Discard CEF Drop CEF Glean Question 18 of 22 19. A co-worker of yours wants to implement DAI and wants to issue the following command on the switch: ip arp inspection validate allow zeros What will be the resultant effect of this configuration? It will configure the switch to compare the ARP body for only valid and expected IP addresses It will configure the switch to compare the ARP body for invalid and unexpected IP addresses It will modify the IP validation test so that ARPs with a sender address of 0.0.0.0 are denied by the switch The configuration is incorrect and will not work It will modify the IP validation test so that ARPs with a sender address of 0.0.0.0 are not denied by the switch Question 19 of 22 20. Which of the following statements about local VLANs are TRUE? Select TWO answers. They are designed for modern-day networks that adhere to the 80/20 rule They becomes extremely complex to maintain as the campus network grows Each VLAN provides common security and resource requirements for members Local VLANs are restricted to a single switch Local VLANs are not restricted to a single switch Question 20 of 22 21. Which of the following is NOT included in the output of the show lacp neighbor command?
