Answers
1. | B Full-duplex Ethernet uses a point-to-point connection between the transmitter of the transmitting station and the receiver of the receiving station. |
2. | D, F You can ping, trace, and telnet to and from all IOS-based switches. For telnet access, the password must be set. |
3. | C The privileged command duplex full sets the duplex of a 2950 interface. |
4. | D Telnet access is protected at the vty interface. |
5. | B The 4000 series of switches uses the set commands. To set a parameter on a certain interface, use the set port command. To enable a port that has been disabled, use the command set port enable slot/port. |
6. | E The 2950 switch command-line interface uses the show interface slot/port command, the same as any router that has modular interface cards. As all ports are 10/100, the FastEthernet description is used. |
7. | C The speed must be set to 10 or 100 before the duplex configuration can be altered. |
8. | A, B The set port command is used to change port parameters, and set port name slot/port description is used to identify the port to an administrator. The first answer is the best one. |
9. | B Use the command hostname name to set the hostname on a 3550 series switch. |
10. | C The maximum distance a Multi-Mode Fiber, 62.5-micron Gigabit Ethernet link can run is 260 meters. |
11. | D Cisco supports up to 10 kilometers for a 1300-nanometer laser run using 9-micron Gigabit Ethernet. |
12. | B FastEthernet point-to-point fiber runs can go a maximum distance of 400 meters. |
13. | A Although many people break this rule, the specifications state that the patch panel-to-switch distance can be only 5 meters. |
14. | D The interface command speed 100 sets the parameters for individual ports. The set port speed port/slot speed command sets the port speed on a 10/100 port. |
15. | C If a device is correctly connected to a port and the device is powered on, the port light-emitting diode (LED) will come on and stay on. |
16. | A The command erase startup-config deletes the configuration file stored in NVRAM on all IOS- based switches. |
17. | A The command that enables you to delete the configuration on a 4000 series switch is clear config all. |
18. | A The interface needs to be identified by the keyword description. |
19. | C The IEEE committee for FastEthernet is 802.3u. |
20. | D The IEEE specification for Gigabit Ethernet is 802.3z. |
