cisco 1 chapter 2

to display a message when a user accesses the switch

A network administrator is configuring the MOTD on switch SW1. What is the purpose of this command?

What models of routers and switches require upgrades?, Do the routers and switches have enough RAM and flash memory for the proposed IOS versions?, What features are required for the devices?

A network administrator is planning an IOS upgrade on several of the head office routers and switches. Which three questions must be answered before continuing with the IOS selection and upgrade?

SSH

A network administrator needs to keep the user ID, password, and session contents private when establishing remote CLI connectivity with a switch to manage it. Which access method should be chosen?

Exit privileged EXEC mode and press Enter

A new network administrator has been asked to enter a banner message on a Cisco device. What is the fastest way a network administrator could test whether the banner is properly configured?

user EXEC mode

A router has a valid operating system and a configuration file stored in NVRAM. The configuration file contains an enable secret password but no console password. When the router boots up, which mode will display?

user EXEC mode

A router has a valid operating system and a configuration stored in NVRAM. When the router boots up, which mode will display?

The no shutdown command was not issued for VLAN 1

A switch was configured as shown. A ping to the default gateway was issued, but the ping was not successful. Other switches in the same network can ping this gateway. What is a possible reason for this?

the PC was preconfigured to use DHCP

A technician is adding a new PC to a LAN. After unpacking the components and making all the connections, the technician starts the PC. After the OS loads, the technician opens a browser, and verifies that the PC can reach the Internet. Why was the PC able to connect to the network with no additional configuration?

1st: user EXEC, 2nd: privileged EXEC, 3rd: global configuration, 4th: line configuration

An administrator is configuring a switch console port with a password. In what order will the administrator travel through the IOS modes of operation in order to reach the mode in which the configuration commands will be entered?

it encrypts passwords that are stored in router or switch configuration files

How does the service password-encryption command enhance password security on Cisco routers and switches?

Tab: completes abbreviated commands and parameters, Space bar displays the next screen, Up arrow scrolls backwards through previously entered commands, ? provides context-sensitive help, Ctrl-shift-6 aborts commands such as trace and ping.

Match the definitions to their respective CLI hot keys and shortcuts. (Tab, Space bar, Up arrow, ?, Ctrl-shift-6)

Console port displays startup, debugging, and error messages by default, and can be used to restore an out-of-box configuration on a switch or router. Virtual interface allows access through use of Telnet or SSH protocols and requires an active network connection. Aux port connects through dialup connections and is not supported on Catalyst switch devices

Match the description to the common IOS CLI access method. (Console port, Virtual Interface, AUX port)

Tab -> Completes abbreviated commands and parameters, Ctrl-R returns directly to the privileged EXEC mode, Up Arrow scrolls backwards through previously entered commands, Ctrl-Z, cancels any command currently being entered and returns directly to privileged EXEC mode, Ctrl-C redisplays, on a new line, the command currently being typed

Match the difinitions to their respective CLI hot keys and shortcuts. (Tab, Ctrl-R, Up arrow, Ctrl-Z, Ctrl-C)

VTY interface, console interface, privileged EXEC mode

Passwords can be used to restrict access to all or parts of the Cisco IOS. Select the modes and interfaces that can be protected with passwords.

no connectivity: PC-C and connectivity: switch 2

Refer to the exhibit. A network technician is testing connectivity in a new network. Based on the test results shown in the exhibit, which device does the technician have connectivity with and which device does the technician not have connectivity with? (Choose two.)

the configuration that is actively running on the device is stored in RAM and the contents of RAM are lost during a power cycle

What are two characteristics of RAM on a Cisco device?

hosts can connect to the network and get an IP address without manual configuration

What benefit does DHCP provide to a network?

ipconfig

What command can be used on a Windows PC to see the IP configuration of that computer?

Each IP address must be unique within the local network

What criterion must be followed in the design of an IPv4 addressing scheme for end devices?

all passwords in the configuration are not shown in clear text when viewing the configuration

What is a result of using the service password-encryption command on a Cisco network device?

if there is connectivity with the destination device

What is a user trying to determine when issuing a ping 10.1.1.1 command on a PC?

the kernel provisions hardware resources to meet software requirements

What is the function of the kernel of the operating software?

the switch can be remotely managed, one device is attached to a physical interface, and the default SVI has been configured

What three facts can be determined from the viewable output of the show ip interface brief command? (Choose three.)

exit

Which command or key combination allows a user to return to the previous level in the command hierarchy?

the contents of the saved configuration file in the NVRAM

Which information does the show startup-config command display?

the switch virtual interface

Which interface allows remote management of a Layer 2 switch?

VLAN 1

Which interface is the default SVI on a Cisco switch?

use the console port to locally access the switch from a serial or USB interface of the PC

Which procedure is used to access a Cisco 2960 switch when performing an initial configuration in a secure environment?

it affects the operation of the device immediately when modified

Which statement is true about the running configuration file in a Cisco IOS device?

numbers, and dashes

Which two characters are allowed as part of the hostname of a Cisco device?

Flash provides nonvolatile storage, and the contents of flash may be overwritten

Which two features are characteristics of flash memory?

displaying a list of all available commands within the current mode and determining which option, keyword, or argument is available for the entered command

Which two functions are provided to users by the context-sensitive help feature of the Cisco IOS CLI?

RM-3-Switch-2A4 and SwBranch799

Which two host names follow the guidelines for naming conventions on Cisco IOS devices?

issue the reload command without saving the running configuration

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?

to identify the device during remote access

Why is it important to configure a hostname on a device?

to enable the switch to be managed remotely

Why would a Layer 2 switch need an IP address?
