Q

While trying to solve a network issue, a technician made multiple changes to the current router configuration file. The changes did not solve the problem and were not saved. What action can the technician take to discard the changes and work with the file in NVRAM?

Issue the reload command without saving the running configuration.

Issue the copy startup-config running-config command.

Delete the vlan.dat file and reboot the device.

Close and reopen the terminal emulation software.

A

Issue the reload command without saving the running configuration.

17
Q

A

the switch virtual interface

18
Q

In the show running-config command, which part of the syntax is represented by running-config ?

a prompt

a variable

the command

a keyword

A

A keyword

19
Q

What function does pressing the Tab key have when entering a command in IOS?

It exits configuration mode and returns to user EXEC mode.

It moves the cursor to the beginning of the next line.

It completes the remainder of a partially typed word in a command.

It aborts the current command and returns to configuration mode.

A

It completes the remainder of a partially typed word in a command.

20
Q

An administrator uses the Ctrl-Shift-6 key combination on a switch after issuing the ping command. What is the purpose of using these keystrokes?

to restart the ping process

to exit to a different configuration mode

to allow the user to complete the command

to interrupt the ping process

A

to interrupt the ping process

21
Q

A technician configures a switch with these commands:

SwitchA(config)# interface vlan 1

Q

How is SSH different from Telnet?

SSH requires the use of the PuTTY terminal emulation program. Tera Term must be used to connect to devices through the use of Telnet.

SSH provides security to remote sessions by encrypting messages and using user authentication. Telnet is considered insecure and sends messages in plaintext.

SSH makes connections over the network, whereas Telnet is for out-of-band access.

A

SSH provides security to remote sessions by encrypting messages and using user authentication. Telnet is considered insecure and sends messages in plaintext.

25
Q

Which device performs the function of determining the path that messages should take through internetworks?

a firewall

a web server

a router

a DSL modem

A

A router

26
Q

Why would a Layer 2 switch need an IP address?

A

to enable the switch to be managed remotely

27
Q

Refer to the exhibit. An administrator is trying to configure the switch but receives the error message that is displayed in the exhibit. What is the problem?

The administrator must first enter privileged EXEC mode before issuing the command.
