100

What is a command useful when determining the status of both physical and virtual interfaces.

show ip interface brief

100

What does a system LED do?

Shows whether the system is receiving power and is functioning properly.

100

What is the first step in recovering from a crash?

Connect a PC by console cable to the switch console port. Configure terminal emulation software to connect to the switch.

100

What is the first step in configuring SSH?

Verify SSH support. Use the show ip ssh command to verify that the switch supports SSH. If the switch is not running an IOS that supports cryptographic features, this command is unrecognized.

Who was our first president.

George Washington

200

What is a command used when configuring the default gateway for a switch.

ip default-gateway

200

What does the Redundant Power Systems (RPS) LED do?

Shows the RPS status. If the LED is off, the RPS is off, or it is not properly connected.

200

What is the second step in recovering from a crash?

Unplug the switch power cord.

200

What is the second step in configuring SSH?

Configure the IP domain. Configure the IP domain name of the network using the ip domain-name domain-name global configuration mode command.

200

What is the dogs name in the novel/ movie Old Yeller?

Old Yeller

300

What is a command that saves the changes made to your switch configurations.

copy running-config startup

300

What is the purpose of a Port Status LED?

Indicates that the port status mode is selected when the LED is green.

300

What is the third step in recovering from a crash?

Reconnect the power cord to the switch and, within 15 seconds, press and hold down the Mode button while the System LED is still flashing green.

300

What is the third step in configuring SSH?

Use the crypto key generate rsa global configuration mode command to enable the SSH server on the switch and generate an RSA key pair. When generating RSA keys, the administrator is prompted to enter a modulus length.

300

What day does new years fall on?

December 31st

400

What is a command used to examine the auto-MDIX setting for a specific interface.

show controllers ethernet-controller

400

What purpose does the Port Speed LED serve?

Indicates the port speed mode is selected. When selected, the port LEDs will display colors with different meanings.

400

What is the fourth step in recovering from a crash?

Continue pressing the Mode button until the System LED turns briefly amber and then solid green; then release the Mode button.

400

What is the fourth and fifth step in configuring the SSH.

4. Configure user authentication. The SSH server can authenticate users locally or using an authentication server. To use the local authentication method, create a username and password pair using the username usernamesecret password global configuration mode command.


5. Configure the vty lines. Enable the SSH protocol on the vty lines using thetransport input ssh line configuration mode command. The Catalyst 2960 has vty lines ranging from 0 to 15. This configuration prevents non-SSH (such as Telnet) connections and limits the switch to accept only SSH connections. Use the line vty global configuration mode command and then thelogin local line configuration mode command to require local authentication for SSH connections from the local username database.

400

What is the closest planet to the sun?

Mars

500

What is a command, which displays the status and statistics information on the network interfaces of the switch.

show interfaces

500

What is the purpose of Port Duplex LED?

 Indicates the port duplex mode is selected when the LED is green. When selected, port LEDs that are off are in half-duplex mode.

500

What is the fifth step in recovering from a crash?

The boot loader switch: prompt appears in the terminal emulation software on the PC.


500

What is the sixth step in configuring the SSH.

Enabling SSH version 2. By default, SSH supports both versions 1 and 2. When supporting both versions, this is shown in the show ip ssh output as supporting version 1.99. Version 1 has known vulnerabilities so its recommended to use version 2.
