100

This field contains an 8-bit binary value that is used to limit the lifetime of the packet

Time to live

100

This is the size of the source address field in bytes

16 bytes

100

This routes traffic to other networks

Default gateway

100

This protocol is used to map IPv4 addresses to MAC addresses

ARP

100

This command is used to configure a default gateway on a switch

ip default-gateway 192.168.0.1

200

This is used to ddetect corruption in the IPv4 header

Header checksum

200

This is what the time to live field from the IPv4 header was renamed to

Hop limit

200

This type of routing is where routes are manually configured

Static routing

200

An IPv6 device uses this message to receive the MAC address of another device with a known IPv6 address

Neighbor solicitation
200

Router(config)# enable secret cisco123

What is this command doing?

Securing privileged EXEC mode

300

This is how long in bytes an IPv4 packet header is

20 bytes

300

This is how long an IPv6 packet header is in bytes

40 bytes

300

In the router's routing table, this entry is used when there is no better match in the IP routing table

Default route

300

This command is used to show the ARP table in a Cisco router

show ip arp

300

This command helps to verify the IPv4 interface configuration

show ip interface brief

400

The flags field is this many bits long

3 bits

400
This is a 20 bit field that suggests all packets with this same field receive the same type of handling by the router

Flow label

400

OSPF and EIGRP are protocols of what type of routing?

Dynamic routing

400

Neighbor solicitation, neighbor advertisement, router solicitation, and router advertisement messages all use this protocol

ICMPv6

400

This command displays the contents of the IP routing tables stored in RAM

show ip route

OR

show ipv6 route

500

This 8 bit field is used to determine the priority of a packet

Differentiated services (or type of service)

500

IPv6 allows for this many unique addresses

340 undecillion addresses 

500

Being connectionless, media independent, and giving best effort are characteristics of what?

IP

500

This is the destination MAC address of an ARP request

FF-FF-FF-FF-FF-FF

500

Router(config-line)# line vty 0 4
Router(config-line)# password cisco123
Router(config-line)# login
