a. arp
&

Address Resolution Protocol (ARP) is used to determine the device MAC address of a known destination device IPv4 address. Neighbor Discovery (ND) is used to determine the MAC address of a known destination device IPv6 address.

What property of ARP causes a reply only to the source sending an ARP request?
a. The source MAC address appears in the header of the Ethernet frame.

what is
a. The source MAC address appears in the header of the Ethernet frame.
9.2
What destination MAC address would be included in a frame sent from a source device to a destination device on a remote local network?
a. a broadcast MAC address of FF-FF-FF-FF-FF-FF
b. The MAC address of the destination device
c. the MAC address of the local router interface
What is
c. the MAC address of the local router interface
When sending a frame to another device on a remote network, the device sending the frame will use the MAC address of the local router interface, which is the default gateway.
Where is the ARP table stored on a device?
a. ROM
b. NVRAM
c. RAM
what is
RAM
The ARP table is cached temporarily in RAM
Which two ICMPv6 messages are used in to determine the MAC address of a known IPv6 address?
a. router advertisement
b. neighbor advertisement
c. neighbor solicitation
what is
b. neighbor advertisement
c. neighbor solicitation
The two ICMPv6 messages used in determining the MAC address of a known IPv6 address are the neighbor solicitation and the neighbor advertisement
What property of ARP allows hosts on a LAN to send traffic to remote networks?
a. Local hosts learn the MAC address of the default gateway.
b. The destination MAC address FF-FF-FF-FF-FF-FF appears in the header of the Ethernet frame.
c. The source MAC address appears in the header of the Ethernet frame.
d. ARP replies are broadcast on the network when a host receives an ARP request.
what is
a. Local hosts learn the MAC address of the default gateway.
9.2 ARP
What statement describes the function of the Address Resolution Protocol?
-ARP is used to discover the IP address of any host on a different network.
-ARP is used to discover the IP address of any host on the local network.
-ARP is used to discover the MAC address of any host on a different network.
-ARP is used to discover the MAC address of any host on the local network.
what is
ARP is used to discover the MAC address of any host on the local network.
When a PC wants to send data on the network, it always knows the IP address of the destination. However, it also needs to discover the MAC address of the destination. ARP is the protocol that is used to discover the MAC address of a host that belongs to the same network.

1.9.2 ARP
What is an attack using ARP?
a. ARP broadcasts
b. ARP hopping attack
c. ARP poisonings
d. ARP starvation
what is
ARP poisioning
Two security issues with ARP Requests are that ARP messages are sent as broadcasts and can be spoofed
To what type of address are ICMPv6 neighbor solicitation messages sent?
a. unicast
b. multicast
c. broadcast
what is
multicast
ICMPv6 neighbor solicitation messages are sent as a multicast
What property of ARP allows hosts on a LAN to send traffic to remote networks?
a. Local hosts learn the MAC address of the default gateway.
b. The destination MAC address FF-FF-FF-FF-FF-FF appears in the header of the Ethernet frame.
c. The source MAC address appears in the header of the Ethernet frame.
d. The port-to-MAC address table on a switch has the same entries as the ARP table on the switch.
what is
a. Local hosts learn the MAC address of the default gateway.
Which two types of IPv6 messages are used in place of ARP for address resolution?
anycast
broadcast
echo reply
echo request
neighbor solicitation
neighbor advertisement
what is
neighbor solicitation
&
neighbor advertisement
IPv6 does not use ARP. Instead, ICMPv6 neighbor discovery is used by sending neighbor solicitation and neighbor advertisement messages.

1.9.3 IPv6 Neighbor Discovery
Which command could be used on a Cisco router to view its ARP table?
a. an ARP cache cannot be manually deleted
b. ARP entries are cached permanently
c. apr -a
what is
c. arp -a
The ARP table is cached temporarily in RAM
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?
a. ipconfig /all
b. route print
c. netstat -r
d. arp -a
what is
D. arp -a
shows the MAC address used to
reach a specific IPv4 address. The analyst
can examine this information to see if it
is the correct MAC address of the default
gateway.
What property of ARP allows MAC addresses of frequently used servers to be fixed in the ARP table?
a. A static IP-to-MAC address entry can be entered manually into an ARP table.
b. Entries in an ARP table are time-stamped and are purged after the timeout expires.
what is
a. A static IP-to-MAC address entry can be entered manually into an ARP table.
9.2 ARP
Which statement describes the treatment of ARP requests on the local link?
-They must be forwarded by all routers on the local network.
-They are received and processed by every device on the local network.
-They are dropped by all switches on the local network.
-They are received and processed only by the target device.
what is
They are received and processed by every device on the local network.
One of the negative issues with ARP requests is that they are sent as a broadcast. This means all devices on the local link must receive and process the request.

c. resolves IPV4 address to MAC addresses
what is
b. maintains a table of IPV4 to MAC address mappings
c. resolves IPV4 address to MAC addresses
ARP has two primary functions: maintains a table of IPV4 to MAC address mappings and determines the MAC addresses of the knwon IPV4 addresses
What type of information is contained in an ARP table?
a. switch ports associated with destination MAC addresses
b. domain name-to-IPv4 address mappings
c. routes to reach destination networks
d. IPv4 address-to-MAC address mappings
what is

What property of ARP causes the request to be flooded out all ports of a switch except for the port receiving the ARP request?
a. The type field 0x806 appears in the header of the Ethernet frame.
b. The destination MAC address FF-FF-FF-FF-FF-FF appears in the header of the Ethernet frame.
what is
b. The destination MAC address FF-FF-FF-FF-FF-FF appears in the header of the Ethernet frame.
