cisco ch 6

Which two interfaces will allow access via the VTY lines to configure the router? (Choose two.)

- WAN interfaces* - LAN interfaces*

Which three commands are used to set up a password for a person who attaches a cable to a new router so that an initial configuration can be performed? (Choose three.)

- line console 0 - password cisco -login

Which two pieces of information are in the RAM of a Cisco router during normal operation?

Cisco IOS* IP routing table*

Which statement describes a hardware feature of a Cisco 1941 router that has the default hardware configuration?

It has two types of ports that can be used to access the console.*

Refer to the exhibit. R1 receives a packet destined for the IP address 192.168.2.10. Out which interface will R1 forward the packet?

Serial0/0/1*

A router boots and enters setup mode. What is the reason for this?

The configuration file is missing from NVRAM.*

When a connectionless protocol is in use at a lower layer of the OSI model, how is missing data detected and retransmitted if necessary?

Upper-layer connection-oriented protocols keep track of the data received and can request retransmission from the upper-level protocols on the sending host.*

Which IPv4 header field is responsible for defining the priority of the packet?​

differentiated services*

24 Which type of static route that is configured on a router uses only the exit interface?

directly connected static route*

What are two characteristics of IP?

does not require a dedicated end-to-end connection* operates independently of the network media*

What is one advantage that the IPv6 simplified header offers over IPv4?

efficient packet handling*

Match the configuration mode with the command that is available in that mode.

enable -> R1> copy running-config startup-config -> R1# login -> R1(config-line)# interface fastethernet 0/0 -> R1(config)#

What are two types of router interfaces?

lan wan

What IPv4 header field identifies the upper layer protocol carried in the packet?

protocol

What routing table entry has a next hop address associated with a destination network?

remote routes*

Which characteristic of the network layer in the OSI model allows carrying packets for multiple types of communications among many hosts?

the ability to operate without regard to the data that is carried in each packet*

Which field in the IPv4 header is used to prevent a packet from traversing a network endlessly?

time to live

What is the purpose of the startup configuration file on a Cisco router?

to contain the commands that are used to initially configure a router on startup*

When connectionless protocols are implemented at the lower layers of the OSI model, what are usually used to acknowledge the data receipt and request the retransmission of missing data?

upper-layer connection-oriented protocols*
