ARP
ND
IP Addresses
MAC Addresses
100
The ARP table is stored in this component of a device.

Random Access Memory (RAM)

100

Neighbor Discovery (ND) utilizes these Layer 3 protocols.

IPv6, ICMPv6

100

A device needs to send a message to another device on a remote network. It will search the ARP table for this IP address.

The IP address of the default gateway

100

An ARP request header contains this destination MAC address.

A broadcast address (FF-FF-FF-FF-FF-FF)

200

An ARP message is encapsulated into this PDU, and does not contain this header.

Ethernet frame, IPv4

200

ICMPv6 messages sent to and from routers utilize these services.

Router Solicitation (RS), Router Advertisement (RA)

200

A device needs to send an ARP request to a device on a remote network. The ARP request header will contain this target IP address.

The IPv4 address of the destination device

200

An ICMPv6 Neighbor/Router Solicitation message contains this destination MAC address.

A special multicast address that belongs to a group with the receiving device

300

This command is used to view the ARP table on a Cisco IOS device.

show ip arp

300

Router discovery is used for dynamic address allocation and this.

Stateless Address Autoconfiguration (SLAAC)

300

The host configuration of a device provides the IP address for this device.

Default gateway

300

A router receives an ARP request that contains an IPv4 address not matching the router's IPv4 address. The router then performs this action(s).

Drops the frame

400

This term refers to a binding between an IPv4 address and a MAC address.

Map

400

Neighbor Discovery is defined in an RFC document created by this standards organization.

Internet Engineering Task Force (IETF)

400

Using ARP spoofing, an ARP poisoning attack can be performed, which is defined as this.

Sending an ARP reply for an IPv4 address belonging to another device.

400

The difference in destination MAC addresses between ARP and ND request messages results in this advantage of ND over ARP.

Improved network performance

500

The type field of an ARP message contains this value.

0x806

500

This Neighbor Discovery service is used for better next-hop selection.

Redirect Message (RM)

500

What type of address (and layer) does a Router use to determine the best path for an IPv4 packet?

The layer 3 destination IPv4 address

500

Does MAC have any roles in communicating outside a local network? Yes/No - give a reason why or why not.

No. Outside of allowing for access to the local default gateway MAC address are only meaningful on the local network and the source & destination MAC addresses change every time a frame gets routed by a router.
