What is a result of using the service password-encryption command on a Cisco network device?
All passwords in the configuration are not shown in clear text when viewing the configuration.*
Match the description to the common IOS CLI access method.
Console port It displays startup, debugging, and error messages by default.* It can be used to restore an out-of-box configuration on a switch or router.* Virtual interface It allows access throught use of Telnet or SSH protocols.* It requires an active network connection.* AUX port It connects throught dialup connections* It is not supported on Catalyst switch devices*

Exit privileged EXEC mode and press Enter.
Which two features are characteristics of flash memory? (Choose two.)
Flash provides nonvolatile storage.* The contents of flash may be overwritten

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.*
Which statement is true about the running configuration file in a Cisco IOS device?
It affects the operation of the device immediately when modified.
How does the service password-encryption command enhance password security on Cisco routers and switches?
It encrypts passwords that are stored in router or switch configuration files.

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?
SSH*
Match the difinitions to their respective CLI hot keys and shortcuts.
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
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?
The PC was preconfigured to use DHCP.
What are two characteristics of RAM on a Cisco device? (Choose two.)
The configuration that is actively running on the device is stored in RAM. * The contents of RAM are lost during a power cycle. *
What is the function of the kernel of an operating software?
The kernel provisions hardware resources to meet software requirements.
What is the function of the kernel of an operating system?
The kernel provisions hardware resources to meet software requirements.*
Refer to the exhibit. 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 no shutdown command was not issued for VLAN 1.*
Which procedure is used to access a Cisco 2960 switch when performing an initial configuration in a secure environment?
Use the console port to locally access the switch from a serial or USB interface of the PC.
Which interface is the default SVI on a Cisco switch?
VLAN 1

Which two functions are provided to users by the context-sensitive help feature of the Cisco IOS CLI? (Choose two.)
displaying a list of all available commands within the current mode* determining which option, keyword, or argument is available for the entered command*
Which command or key combination allows a user to return to the previous level in the command hierarchy?
exit
What is a user trying to determine when issuing a ping 10.1.1.1 command on a PC?

second mode final mode third mode first mode
Which information does the show startup-config command display?
the contents of the saved configuration file in the NVRAM *
Which interface allows remote management of a Layer 2 switch?
the switch virtual interface
Refer to the exhibit. A network administrator is configuring the MOTD on switch SW1. What is the purpose of this command?
to display a message when a user accesses the switch*
Why would a Layer 2 switch need an IP address?
to enable the switch to be managed remotely
Why is it important to configure a hostname on a device?
to identify the device during remote access (SSH or telnet)
