Section 3
1) Its seven-layered approach to data transmission divides the operations into specific related
groups of action at each layer:
→ OSI Model
2) It’s a protocol stack that consists of multiple protocols including TCP (Transmission Control
Protocol ) and IP(Internet protocol):
→ TCP/IP Stack
3) Which OSI layer provides network service to the application of the user :
→ Application layer
4) The OSI ….. layer ensures that the information that is sent at the application layer of one
system is readable by the application layer of another system :
→ Presentation layer
5) The OSI …. layer establishes, manages, and terminates session between two communicating
hots:
→ Session
6) which OSI layer defines the specification needed for activating maintaining, and deactivating
the physical link between end devices :
→ Physical layer
7) the OSI … layer defines how data is formatted for transmission and how access to physical
media is controlled :
→ Data link
8) This OSI layer defines to segment, transfer and reassemble the data for individual
communication between the end devices:
→ Transport layer
9) This OSI layer provides connectivity and path selection between two hosts system that may be
located on geographically separated networks :
→ Network layer
10) OSI model and TCP/IP model
Section 4
1) The Cisco operating system used on the majority of cisco enterprise grade network devices :
→ IOS
2) You can enter a ……. to access help :
→ Question mark
3) Where is the ISO operating systems image stored :
→ Flash
4) Where is the startup configuration is stored :
→ NVRAM
5) This command drops you back to the privilege Exec mode from any level :
→ end
6) the …. command drops you back down a level in the Cisco IOS CLI
→ Exit
7) What cable will you use for a direct connection to the console port on the router or switch :
→ Console cable
8) the …. is loaded into RAM from the startup config when the device boats up :
→ Running configuration
9) what Cisco IOS command line mode is ‘Router>’ in :
→ User Exec mode
10) Router(config)# is in …. node :
→ Global configuration mode
11) the ….. command is entered to access the global configuration mode from the privilege exec
mode :
→ Configure terminal
12) what Cisco IOS command line mode is ‘router(config-if)#’ in :
→ interface configuration mode
13) the ….. is the configuration that will go into effect when the router is next started a rebooted:
→ the startup configuration
14) command that are entered in the running configuration do not get saved permanently until you
explicitly copy them from the ….. to the ……
→running configuration to the startup configuration
15) this command is used to go to the privileged exec mode from the user exec mode
→ enable
16) ‘router#’ is in Cisco IOS …… mode:
→ privileged exec
17) this command makes the running configuration persistent across reboot:
→ copy running-config startup-config or copy run start
18) the running configuration is stored in the :
→ RAM
19) the ‘show’ and ‘debug’ commands are entered in :
→ privilege exec mode
20) the ‘show’ command that displays the entire running configuration on the route :
→ show run or show running-config
