Question 1 2 / 2 pts A technician configures a switch with these commands: SwitchA(config)# interface vlan 1 SwitchA(config-if)# ip address 192.168.1.1 255.255.255.0 SwitchA(config-if)# no shutdown What is the technician configuring?
Telnet access Correct!
SVI
encryption
physical switchport access Refer to curriculum topic: 2.3.2 For a switch to have an IP address, a switch virtual interface must be configured. This allows the switch to be managed remotely over the network.
Question 2 2 / 2 pts When a hostname is configured through the Cisco CLI, which three naming conventions are part of the guidelines? (Choose three.) Correct!
the hostname should be fewer than 64 characters in length
the hostname should be written in all lower case characters Correct!
the hostname should contain no spaces
the hostname should end with a special character Correct!
the hostname should begin with a letter Refer to curriculum topic: 2.2.1 A hostname can be configured with upper or lower case characters and should end with a letter or digit, not a special character. A hostname should start with a letter and no space is allowed for a hostname.
Question 3 2 / 2 pts An IT technician has manually configured an IP address on a laptop for a new employee. Each time the employee tries to connect to the LAN, the employee receives a duplicate IP address error message. What can the company do to prevent this situation from arising again?
Configure the IP address on an SVI on the laptop.
Use a virtual private network instead of the company LAN.
Correct!
Use DH to automatically assign addresses.
Use laptops that do not require IP addresses. Refer to curriculum topic: 2.3.2 Asg IP addresses automatically using DH will greatly eliminate the chance of a duplicate IP address error.
Question 4 2 / 2 pts Fill in the blank. The component of the operating software that provides the interface is called the
. shell
Answer 1: Correct!shell Refer to curriculum topic: 2.1.1 Operating systems function with a shell, a kernel, and the hardware. The shell interfaces with the s, allowing them to request specific tasks from the device. The kernel provisions resources from the hardware to meet software requirements. The hardware functions by using drivers and their underlying electronics. The hardware represents the physical components of the device.
Question 5 2 / 2 pts An has just changed the IP address of an interface on an IOS device. What else must be done in order to apply those changes to the device?
Copy the running configuration to the startup configuration file.
Copy the information in the startup configuration file to the running configuration.
Reload the device and type yes when prompted to save the configuration. Correct!
Nothing must be done. Changes to the configuration on an IOS device take effect as soon as the command is typed correctly and the Enter key has been pressed. Refer to curriculum topic: 2.2.3 Changes to router and switch configurations take effect as soon as the command is entered. For this reason, it is very important that changes to live production devices are always carefully planned before being implemented. If commands are entered that render the device unstable or inaccessible, the device may have to be reloaded, resulting in network downtime.
Question 6 2 / 2 pts To save time, IOS commands may be partially entered and then completed by typing which key or key combination? Correct!
Tab
Ctrl-P
Ctrl-N
Up Arrow
Right Arrow
Down Arrow Refer to curriculum topic: 2.1.4
Question 7 2 / 2 pts Why would a technician enter the command copy startup-config running-config?
to remove all configurations from the switch
to save an active configuration to NVRAM Correct!
to copy an existing configuration into RAM
to make a changed configuration the new startup configuration Refer to curriculum topic: 2.2.3 Usually, changes are made to a running configuration in RAM and copied to NVRAM. However, in this case, the technician wants to copy a previously saved configuration from NVRAM into RAM in order to make changes to it.
Question 8 2 / 2 pts
Fill in the blank. In order to test end-to-end connectivity, you would use the
command. ping
Answer 1: Correct!ping Correct Answer trace Correct Answer traceroute Correct Answer tracert Refer to curriculum topic: 2.3.3 Connectivity between two end devices can be tested using the ping, tracert, or traceroute commands.
Question 9 2 / 2 pts Which two functions are provided to s by the context-sensitive help feature of the Cisco IOS CLI? (Choose two.)
providing an error message when a wrong command is submitted Correct!
displaying a list of all available commands within the current mode
allowing the to complete the remainder of an abbreviated command with the TAB key Correct!
determining which option, keyword, or argument is available for the entered command
selecting the best command to accomplish a task Refer to curriculum topic: 2.1.4 Context-sensitive help provides the with a list of commands and the arguments associated with those commands within the current mode of a networking device. A syntax checker provides error checks on submitted commands and the TAB key can be used for command completion if a partial command is entered.
Question 10 2 / 2 pts How is SSH different from Telnet?
SSH makes connections over the network, whereas Telnet is for out-of-band access. Correct!
SSH provides security to remote sessions by encrypting messages and using authentication. Telnet is considered insecure and sends messages in plaintext.
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 must be configured over an active network connection, whereas Telnet is used to connect to a device from a console connection. Refer to curriculum topic: 2.1.2 SSH is the preferred protocol for connecting to a device operating system over the network because it is much more secure than Telnet. Both SSH and Telnet are used to connect to devices over the network, and so are both used in-band. PuTTY and Terra Term can be used to make both SSH and Telnet connections.
Question 11 2 / 2 pts s can be used to restrict access to all or parts of the Cisco IOS. Select the modes and interfaces that can be protected with s. (Choose three.) Correct!
VTY interface Correct!
console interface
Ethernet interface
boot IOS mode Correct!
privileged EXEC mode
router configuration mode Refer to curriculum topic: 2.2.2 Access to the VTY and console interfaces can be restricted using s. Out-of-band management of the router can be restricted in both EXEC and privileged EXEC modes.
Question 12
2 / 2 pts Which device acts as a gateway to allow hosts to send traffic to remote IP networks?
DNS server
DH server Correct!
local router
local switch Refer to curriculum topic: 2.3.1 For hosts to reach remote networks, they must send traffic to a local router that can route the traffic to the correct destination network. This local router is known as the default gateway and hosts must be configured with this address in order to communicate with devices on remote networks.
Question 13 2 / 2 pts Which two statements are true regarding the EXEC mode? (Choose two.)
All router commands are available.
Global configuration mode can be accessed by entering the enablecommand. Correct!
The device prompt for this mode ends with the ">" symbol.
Interfaces and routing protocols can be configured. Correct!
Only some aspects of the router configuration can be viewed. Refer to curriculum topic: 2.1.3 EXEC mode limits access to some show and debug commands. It is the first level of interface encountered when configuring a router and is intended for investigation of certain functions of the device. The EXEC prompt is identified with the ">" symbol.
Question 14 2 / 2 pts What command will prevent all unencrypted s from displaying in plain text in a configuration file?
(config)# enable secret
(config)# enable secret Secret_
(config-line)# secret Correct!
(config)# service -encryption
(config)# enable secret Encrypted_ Refer to curriculum topic: 2.2.2 To prevent all configured s from appearing in plain text in configuration files, an
can execute the service -encryption command. This command encrypts all configured s in the configuration file.
Question 15 2 / 2 pts True or False? Mobile devices do not require IP addresses to communicate on the Internet.
True Correct!
False Refer to curriculum topic: 2.3.1 All devices that communicate over data networks need unique IP addresses.
