Module 17 - Cisco Switches and Routers Quiz
A technician is setting up a network in a new room. What is the best device to use to connect the PCs to each other and to the rest of the LAN? A. switch B. gateway C. router D. firewall
A. switch A gateway is a router used to interconnect networks and is not necessary in this situation. A hub does not segment a network and allows collisions to take place on the network segment. A switch will interconnect all the devices in a LAN.
Name two ports can be used for the initial configuration of a Cisco router?
Aux , console port The AUX and console ports on a Cisco 1941 router can be used to perform initial setup. The initial setup does not require that the router be connected to a network. A network administrator uses a computer to connect to the console ports directly. A network administrator can also access the router remotely through a dialup phone line and a modem connected to the AUX port. LAN and WAN interfaces are used to connect to networks. The flash slots expand storage capability through the use of a compact flash card.
During normal operation, from which location do most Cisco switches run the IOS? A. RAM B. flash C. NVRAM D. disk drive
C. RAM When a Cisco switch is powered on, the IOS is copied into RAM. The switch then runs the IOS from RAM, thus enhancing operating performance.
Which two commands would return you to the privileged EXEC prompt (not to user EXEC mode!) regardless of the configuration mode you are in? (Choose two.)
CTRL + Z ( Ctrl + c abort the command) end
During troubleshooting procedures, from which location will most Cisco routers load a limited IOS?
ROM (read only memory) ROM is used to store bootup instructions, basic diagnostic software, and a copy of a limited IOS. NVRAM stores the startup configuration file. RAM provides temporary storage of the running configuration file. Flash is used to store the full Cisco IOS on a device.
What is the first action in the boot sequence when a switch is powered on?
The first action to take place when a switch is powered on is the POST or power-on self-test. POST performs tests on the CPU, memory, and flash in preparation for loading the boot loader.
Which information does the show running-config command display?
The show running-config command displays the contents of the currently running configuration file located in RAM.
Which information does the show startup-config command display?
The show startup-config command displays the saved configuration located in NVRAM.
Name two files are loaded into RAM of a Cisco switch when it is booted?
When a Cisco device boots, it loads the IOS image file and startup configuration files into RAM.
Which two networking devices are used in enterprise networks (iow local networks) for providing network connectivity to end devices? (Choose two.)
Wireless access points (AP) and LAN switches are deployed in enterprise networks to allow end devices to connect to the network wirelessly or through cables. A router is used to enable end devices on a local network to communicate with other devices on remote networks. A firewall protects a network by filtering incoming and outgoing traffic. A web server hosts web content.
When a router is powered on, where will the router first search for a valid IOS image to load by default?
flash memory By default, if no boot system commands are in the configuration, a router will load the first valid Cisco IOS image in flash memory and run it. RAM is active memory that is not used to store image files. NVRAM (non-volatile random (not rapid) access memory) stores configuration files. ROM stores a minimal version of the Cisco IOS image that can be used to provide limited functions if a valid IOS image is not available in flash memory.
Which IOS mode are you in if the Switch(config)# prompt is displayed?
global configuration mode (inside privileged EXEC mode) the command from privileged EXEC mode wld be configure terminal
Which IOS mode allows access to all commands and features?
privileged EXEC mode
What are two functions of NVRAM? (name two.)
to retain contents when power is removed to store the startup configuration file NVRAM is permanent memory storage, so the startup configuration file is preserved even if the router loses power.
Which IOS mode are you in if the Switch> prompt is displayed?
user EXEC mode
