Question 6

When making configuration changes, the following message is constantly displayed, sometimes as you are typing:

%SYS-5-CONFIG_1: Configured from console by console

Answer 6

Command:
logging synchronous and no logging console

Description:
The logging synchronous command causes logging messages to be displayed above the command line instead of interrupting your requested session output and prompts. You can use the no logging console command to turn off these messages.

Question 7

The session automatically disconnects at the wrong time.

Answer 7

Command:
exec-timeout min sec

Description:
You want to maintain a session timeout for security reasons. However, if you are frequently getting timeouts while you are working, you may consider extending the timeout period. You can use exec-timeout to configure the time interval that the EXEC command interpreter waits before it disconnects the incoming session when no user input is detected.

Question 8

When working with the device through a Telnet session, using a debug command displays no output.

Answer 8

Command:
terminal monitor

Description:
The terminal monitor command displays debugging output to the terminal session.

Question 9

When viewing debug information, you want to review previous information. Or, debug information is shown too quickly for you to examine it.

Answer 9

Command:
logging buffered and show log

Description:
You can send logging information to RAM by entering logging buffered. You can then view the information one screen at a time by entering show log.

Removes the specified banner.

Question 15

You are troubleshooting a router at the console. You issued the following command at the CLI:

pdx#debug arp

You see debug output, but the output scrolls past faster than you can read. What two commands allow you to view debug output one page at a time? (Select two.)

Answer 15

Use the logging buffered command to send debug output to RAM, which you can then view one page at a time with the show log command.

Question 16

You have a test lab that you use to test different configurations before deploying them in your live network. You have been testing several commands from configuration mode, then going back to enable mode to view the running configuration. Every time you exit configuration mode, the following output is displayed:

%SYS-5-CONFIG_I: Configured from console by console

What command can stop these messages from appearing on your screen?

Answer 16

The IOS generates messages when different events occur. These events are called syslog messages. By default, the console port always receives syslog messages. The no logging console command tells the router not to send syslog messages to the console.

Question 17

You would like to see logging message from IOS appear on the terminal. However, IOS does not send log messages to a terminal session over IP when using a remote SSH session. What command would send terminal output to the terminal session?

Answer 17

The terminal monitor command displays debugging output to the terminal session.

The logging synchronous command causes logging messages to be displayed above the command line instead of interrupting your requested session output and prompts.

You can use the show log command to show logs.

You can send logging information to RAM by entering logging buffered. You can then view the information one screen at a time by entering show log.

Question 18

When you start up your router, you see the following messages:

Have a nice day!
The grass grows green
User Access Verification

Password:
The sky is blue
Router>

For security purposes, you would like to change the message The grass grows green to read Only administrator access is allowed. Which command should you use?

Answer 18

The login banner shows immediately before the User Access Verification line. The first banner to display is the motd (message of the day) banner. The exec banner displays after a successful login.
