what are the advantages that the IPv6 simplified header offers over IPv4

efficient packet handling

describe the hardware features of a cisco 1941 router that has a default hardware configuration

it has 2 types of parts that can be used to access the console

which 3 commands are used to set up secure access to a router through a connection to the console interface

line console 0 login password cisco

which route from the PC1 routing table will be used to reach PC2

192.168.10.0 255.255.255.0 on-link 192.168.10.0 281

2 characteristics of IP are that it operates independently of this and requires this type of connection

does not require an end to end connection. operates independently of the network media

what are 2 types of router interfaces

LAN and WAN

copy running-config startup-config

R1#

service password encryption

R1(config)#

ip address 192.168.4.4 255.255.255.0

SW1 doesn`t have a default gateway configured

what information is in the RAM of a cisco router during a normal operation

cisco IOS

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

the ability to operate without regard to the data that is carried into the packet

which field in the IPv4 header is used to prevent a packet from transversing a network endlessly

time to live

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 recieved and can request retransmission from the upper level protocols of sending host

why does a router enter setup mode as it boots up

configuration file is missing from NVRAM

what is the purpose of the startup configuration file on a cisco router

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

what type of route is indicated by the code C in an IPv4 routing table on a cisco router

directly connected route

following default settings what is the next step in the router boot sequence after the IOS loads from flash

locate and load the start up config file from NVRAM

if R1 recieves a packet destined for the IP address 192.168.2.10. out which interface will R1 forward the packet?

serial 0/0/1

describe the characteristics of an IPv6 enhancement over IPv4

the IPv6 header is simpler than the IPv4 header is which improves packet handling
