| Question 1 | If you are receiving a duplicate MAC address error, which of the following commands will show the MAC address of all nodes attached to a Set/Clear based IOS switch or a Cisco CLI based switch? [Choose all that apply.] |
| A1: | Answer: D, E . The CAM table on a Set/Clear based switch is used to keep all the MAC addresses of all the attached nodes on each port. The show cam dynamic command is used to view those addresses. The show cam static command can be used if port security is in place on the switch. On a Cisco CLI based switch, such as the 4500 series, the command to view the dynamically collected MAC addresses is show mac-address-table . |
| Question 2 | To determine the amount of time the switch has been up since the power was last recycled, which of the following commands would be used? -
A. show all -
B. show uptime -
C. show config -
D. show version |
| A2: | Answer: D . You can use the show version command to determine the amount of time the switch has been up since the switch was last rebooted. |
| Question 3 | Which of the following Catalyst switch commands enable you to gather statistics regarding the Spanning Tree Protocol? [Choose the two best answers.] -
A. show span -
B. show vlan -
C. show spantree -
D. show port spantree |
| A3: | Answer: C, D . This question is somewhat tricky because of the similarities in the commands. The show span command is also a valid answer, but it gives statistics related to the switched port analyzer, so it is wrong. |
| Question 4 | The Catalyst 5000 switch's utilization statistics can be viewed by which of the following commands? [Choose the two best answers.] -
A. Viewing LEDs on the Ethernet Module -
B. Using the show test command -
C. Using Cisco software such as CWSI -
D. Using the show all command -
E. Viewing the Load LED on the Supervisor Engine module -
F. All of the above |
| A4: | Answer: C, E . Some CLI-based commands can aid in getting utilization statistics, but the only two valid answers shown are C and E. |
| Question 5 | Which of the following cable types cannot support Ethernet 100BaseTX traffic? -
A. Category 5 -
B. Category 3 -
C. Category 6 -
D. All of the above |
| A5: | Answer: B . Category 3 cable can support 10BaseTX but not 100BaseTX. Both Category 5 and 6 can support 100 Mbps data traffic over Ethernet. |
| Question 6 | Which of the following commands provides information such as the status and errors on an Cisco Catalyst 5000's Ethernet Module port? -
A. show all -
B. show port -
C. show port config -
D. show port all |
| A6: | Answer: B . The show port command, followed by the module number and port number, is used by the switch to display the port status and error counters on a Set/Clear based switch. |
| Question 7 | Spanning Tree Protocol stops data loops by placing redundant ports in which of the following states? -
A. Stopped -
B. Disabled -
C. Closed -
D. Blocked |
| A7: | Answer: D . Spanning Tree Protocol places redundant ports in the Blocked state. The Disabled state is placed on a port by an administrator or the switch, not by STP, if a hardware problem exists. |
| Question 8 | If two paths, such as a primary path and a secondary path, exist between two points in the network, the second path is referred to as which of the following? -
A. A cheaper path -
B. A redundant path -
C. A forced path -
D. A helper path |
| A8: | Answer: B . The second path between two destinations in a network is called the redundant path. |
| Question 9 | Which of the following is not a timer used to influence the convergence time of STP? -
A. Hello Time -
B. MaxAge Time -
C. Link State Time -
D. FwdDelay |
| A9: | Answer: C. The Link State Time is not a timer used to influence the convergence time of STP. |
| Question 10 | Without loop avoidance schemes in place, which of the following is a worst-case scenario? |
| A10: | Answer: B. A broadcast storm, which is a total halt to the network, is the worst-case scenario resulting from data loops in the network. |
