ITCC 1414 Chapter 9.3
Which two ICMPv6 messages are used in to determine the MAC address of a known IPv6 address?
Neighbor Advertisement Neighbor Solicitation
Which destination address is used in an ARP request frame?
FFFF.FFFF.FFFF
How are the IP addresses of the IP packets in a data flow associated with the MAC addresses on each link along the path to the destination?
For IPv4 packets, this is done through a process called ARP. For IPv6 packets, the process is ICMPv6 ND.
What type of information is contained in an ARP table?
IPv4 address to MAC address mappings
What addresses are mapped by ARP?
IPv4 address to a destination MAC address
Which action is taken by a Layer 2 switch when it receives a Layer 2 broadcast frame?
It sends the frame to all ports except the one from which it was received.
The ARP table in a switch maps which two types of address together?
Layer 3 address to a layer 2 address
To what type of address are ICMPv6 neighbor solicitation messages sent?
Multicast
Which two ICMPv6 messages are used during the Ethernet MAC address resolution process?
Neighbor advertisement Router solicitation
Which two ICMPv6 messages are used in SLAAC?
Router Advertisement Router Solicitation
A PC is configured to obtain an IPv4 address automatically from network 192.168.1.0/24. The network administrator issues the arp -a command and notices an entry of 192.168.1.255 ff-ff-ff-ff-ff-ff. Which statement describes this entry?
Static map entry
When an IPv4 packet is sent to a host on a remote network, what information is provided by ARP?
The MAC address of the router interface that is closest to the sending host
A cybersecurity analyst believes an attacker is spoofing the MAC address of the default gateway to perform a man-in-the-middle attack. Which command should the analyst use to view the MAC address a host is using to reach the default gateway?
arp-a
What will a Layer 2 switch do when the destination MAC address of a received frame is not in the MAC table?
it forwards the frame to all ports except the port at which the frame was received
How does the ARP process use an IPv4 address?
to determine the MAC address of a device on the same network
What is the purpose of ARP in an IPv4 network?
to obtain a specific MAC address when an IP address is known
