Module 9.4.2 - ARP and Networking Questions

Which destination address is used in an ARP request frame?

• 0.0.0.0

• 255.255.255.255

• FFFF.FFFF.FFFF

• 127.0.0.1

• 01-00-5E-00-AA-23

What addresses are mapped by ARP?

• IPv4 address to a destination MAC address

• destination IPv4 address to the source MAC address

• destination IPv4 address to the destination host name

• destination MAC address to the source IPv4 address

What will a Layer 2 switch do when the destination MAC address of a received frame is not in the MAC table?

• It initiates an ARP request.

• It broadcasts the frame out of all ports on the switch.

• It notifies the sending host that the frame cannot be delivered.

• It forwards the frame out of all ports except for the port at which the frame was received.

Which two ICMPv6 messages are used during the Ethernet MAC address resolution process?

• router solicitation

• router advertisement

• neighbor solicitation

• neighbor advertisement

• echo request

Which router component holds the routing table, ARP cache, and running configuration file?

• RAM

• Flash

• NVRAM

• ROM

What type of information is contained in an ARP table?

• switch ports associated with destination MAC addresses

• domain name to IP address mappings

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?

• This is a static map entry.

• This is a dynamic map entry.

• This entry refers to the PC itself.

• This entry maps to the default gateway.

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?

• ipconfig /all

• route print

• netstat -r

• arp -a

What is a function of ARP?

• resolving MAC addresses to IPv4 addresses

• resolving port addresses to MAC addresses

• resolving MAC addresses to port addresses

• resolving IPv4 addresses to MAC addresses

What is the purpose of ARP in an IPv4 network?

• to forward data onward based on the destination IP address

• to obtain a specific MAC address when an IP address is known

• to forward data onward based on the destination MAC address.

• to build the MAC address table in a switch from the information that is gathered.
