Configuring a Cisco Router Flashcards
In which stage does the router load the Cisco IOS Software image?
A. during POST
B. during the software initialization stage
C. while loading the configuration file
D. immediately after switching on the router
B. during the software initialization stage
The correct answer is “during the software initialization stage.” After verifying the hardware functions, the router proceeds with software initialization. During software initialization, the router finds and loads the Cisco IOS image.

In which three ways can you use Cisco Discovery Protocol? (Choose three.)
A. to determine the hardware platform of connected Cisco devices
B. to allow a switch to discover the Cisco devices that are connected to its ports
C. to determine the IPv4 addresses of connected Cisco devices
D. to determine the users that are connected to Cisco devices
E. to determine the environmental parameters of the connected Cisco devices (temperature, humidity, and so on)
F. to determine the system usage of the connected Cisco devices (memory, CPU, disk, and so on)
A. to determine the hardware platform of connected Cisco devices
B. to allow a switch to discover the Cisco devices that are connected to its ports
C. to determine the IPv4 addresses of connected Cisco devices
Which option represents the Cisco IOS Software command and the mode that is used to disable Cisco Discovery Protocol on a single interface?
A. router(config-if)# no cdp enable
B. router(config)# no cdp enable
C. router(config-if)# no cdp run
D. router(config)# no cdp run
A. router(config-if)# no cdp enable
Correct answer is “router(config-if)# no cdp enable.” To disable Cisco Discovery Protocol on an interface, use the no cdp enable interface command.
Which Cisco IOS commands can be used to enable LLDP on an interface level? (Choose two.)
A. lldp transmit
B. lldp receive
C. lldp run
D. [no] lldp transmit
E. [no] lldp receive
A. lldp transmit
B. lldp receive
Which two options represent details about the neighbor router that the show cdp neighbor detail command displays? (Choose two.)
A. device ID
B. routing protocol
C. hello value in seconds
D. hardware platform
E. list of ports that are shut down
A. device ID
D. hardware platform
When using the show run | include hostname command on the Branch router, what is the expected result?
A. hostname Branch
B. hostname router
C. Branch
D. router
A. hostname Branch
Which command verifies that the description is configured on the Ethernet0/0 interface?
A. show run interface e0/0
B. show run | include description e0/0
C. show ip interface brief
D. show version
A. show run interface e0/0
Refer to the exhibit. It shows a successful connectivity check. The output in the exhibit shows the source address for the ping command, i.e. the address from which the ping messages were sent. Which device and interface was the ping sent from?
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 172.16.130.5, timeout is 2 seconds:
Packet sent with a source address of 172.16.2.2
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 m
A. Branch router, interface Ethernet 0/0
B. Branch router, interface Loopback 0
C. AdminPC, interface Ethernet 0/0
D. SW1 switch, interface VLAN 1.
B. Branch router, interface Loopback 0
The correct answer is “Branch router, interface Loopback 0.” The Branch router Loopback0 interface has IP address 172.16.2.2, which is used as source for the ping command.
If POST completes during a startup of a Cisco device and there is no configuration file, what does the router do?
A. It reboots.
B. It initiates initial configuration through “setup.”
C. It creates a configuration file with default settings and boots that file.
D. It shuts down the router.
B. It initiates initial configuration through “setup.”
Which command configures IPv4 address 10.0.0.1/28 on a selected router interface?
A. Router(config-if)# ip address 10.0.0.1 255.255.255.240
B. Router(config-if)# ip address 10.0.0.1/28
C. Router(config-if)# ip address 10.0.0.1 255.255.255.0
D. Router(config-if)# ip address 10.0.0.0 255.255.255.240
E. Router(config-if)# ip address 10.0.0.1/24
A. Router(config-if)# ip address 10.0.0.1 255.255.255.240
