| 1. | When Cisco IOS Software is used on a Catalyst switch, the switch must perform routing. True or false? |
| Answer: | False |
| 2. | What is the major difference between the Cisco IOS Software and CatOS command sets? |
| Answer: | Cisco IOS Software uses the familiar router configuration commands and a hierarchy of configuration modes. CatOS uses set commands with no explicit configuration mode. Also, IOS configuration commands are not saved automatically across a power failure, whereas CatOS commands are. IOS also offers the capability to switch packets at Layer 3, whereas CatOS never was extended beyond Layer 2. |
| 3. | What switch command will enter privileged EXEC or "enable" mode on a Catalyst 4500? |
| Answer: | enable |
| 4. | Match these default command-line prompts with their respective modes: a. Switch# | ____Normal user EXEC mode | b. Switch(config) | ____Privileged EXEC or enable | c. Switch(config-if)# | ____Global configuration | d. Switch> | ____Interface configuration |
|
| Answer: | __d__ | Normal user EXEC mode | __a__ | Privileged EXEC or enable | __b__ | Global configuration | __c__ | Interface configuration |
|
| 5. | With the command-line prompt testlab#, what command has been used to customize the prompt? |
| Answer: | hostname testlab |
| 6. | The following commands have just been entered, assuming that interface VLAN 10 did not previously exist: interface vlan 10 ip address 192.168.199.10 255.255.255.0 no shutdown
Suddenly, the power cord is pulled out of the switch. What will happen when the power is restored? |
| Answer: | Not only will interface VLAN 10 have no IP address, but there will not even be an interface VLAN 10. Those commands were entered into the running-config configuration file, so they were not applied permanently. When the power is restored, the contents of the startup-config will be read and executed. Because the running-config was not saved, the VLAN 10 commands no longer will exist. |
| 7. | Can you configure an enable secret password (enable secret password) for the switch console and a different enable secret password for Telnet access? |
| Answer: | No, only one global enable secret password is allowed, and it applies to all lines on the switch. |
| 8. | When you configure an IP address and subnet mask on a Layer 2 switch for management purposes, which VLAN are you required to use? VLAN 1. VLAN 0. VLAN 1001. Any VLAN that is appropriate. You cannot assign an IP address to a VLAN.
|
| Answer: | d |
| 9. | What commands will allow Telnet and ping access to a switch-management interface at 192.168.200.10, subnet mask 255.255.255.0, on VLAN 5? A router is available at address 192.168.200.1. |
| Answer: | interface vlan 5 ip address 192.168.200.10 255.255.255.0 ip default-gateway 192.168.200.1 no shutdown interface vlan 5 ip address 192.168.200.10 255.255.255.0 ip default-gateway 192.168.200.1

| 10. | CDP advertisements occur every _______ seconds. |
| Answer: | 60 |
| 11. | When a Cisco Catalyst switch receives a CDP multicast frame, it relays it to neighboring switches. True or false? |
| Answer: | False |
| 12. | Eight access-layer switches connect to a central distribution-layer switch using Gigabit Ethernet connections. Each connection is assigned to VLAN 1 so that no link is in trunking mode. On one of the access switches, how many neighboring switches will be shown by the show cdp neighbor gigabit 0/1? |
| Answer: | Only one neighboring switch will be shownthe single distribution-layer switch that is connected directly. CDP messages are not forwarded; they are received and processed only by the neighboring switch. Because all eight access switches are connected by another switch, CDP messages don't pass between them. |
| 13. | Which Cisco IOS Software image file is more recent: c3550-i5q3l2-mz.121-12c.EA1.bin or c3550-i9q3l2-mz.121-11c.EA1.bin? |
| Answer: | c3550-i5q3l2-mz.121-12c.EA1.bin |
| 14. | A new switch has just been configured with 100 command lines from the console. You realize the need to save the new configuration and type copy start run. Where will your configuration be stored? |
| Answer: | Unfortunately, the configuration you made might be lost or drastically changed. The startup-config file will be copied into, or overlaid onto, the running-config. Any commands that are different in the startup-config will overwrite the commands you entered in the running-config. Because this is a new switch containing only the default commands, you could end up effectively overwriting your changes with the default values that the switch had when it powered up for the first time. The correct command should have been copy run start. |
| 15. | What command can you use to see what Cisco IOS software version currently is running on a switch? |
| Answer: | show version |
| 16. | Complete this command so that the output is displayed starting with the configuration for interface VLAN 100: show run ______ |
| Answer: | | begin Vlan100 |
| 17. | The debug spanning-tree all command has been given from the EXEC mode command line. What commands can you use to stop or disable the debugging output? |
| Answer: | no debug all no debug spanning-tree all undebug all
|
| 18. | What command can you use to verify CDP configuration on switch port GigabitEthernet 3/1? |
| Answer: | show cdp interface gigabit 3/1 |
