Module 9-Address Resolution Protocol

What is the purpose of ARP in an IPv4 network?

• To forward data to a remote network based on the destination IP address.

• To discover the MAC address of a known IP address.

• To forward data based on the known destination MAC address.

• To discover the IP address of a known MAC address.

Which address is examined by a device to determine if a received frame was intended for it?

• Source IP address

• Destination IP address

• Source MAC address

• Destination MAC address

Which destination address is used in an ARP broadcast frame to require all devices on the local network to process the frame?

• 0.0.0.0

• 255.255.255.255

• 01-00-5E-00-AA-23

• FF-FF-FF-FF-FF-FF

How does an interface respond to an ARP request when the interface IP address does not match the destination IP address in the frame?

• The system replies to the frame with a denial unicast message.

• The system drops the frame.

• The system forward the frame to the correct destination.

• The system replies back with a broadcast denial to update the switch.

Which of the following statements regarding frame forwarding is correct?

• A host cannot ping itself.

• Local hosts can reach each other without the need of a router.

• A remote destination host is on the same local network as the sending host.

• Router is enabled on switches to discover the best path to a destination.

What information is recorded by a switch to build its MAC address table?

• The destination MAC address & IP address of incoming packets.

• The source MAC address & the port on which the frame was received.

• The source IP address of outgoing packets.

• The destination MAC address of outgoing frames.

Which networking table on a PC maps host MAC addresses to IPv4 addresses?

• Routing table

• ARP cache

• MAC Address table

• Neighbor Discovery table

Which networking table maps on a switch maps the IPv4 MAC address to its connected switch port?

• MAC Address table

• Routing table

• ARP table

• Neighbor Discovery table

Which IPv6 protocol is used for MAC address resolution?

• DHCP

• ARP

• DNS

• Neighbor Discovery

When an IPv4 packet is destined for a host on a remote network, what address is provided by ARP?

• The MAC address of the connected switch port.

• The IPv4 address of the default gateway.

• The MAC address of the default gateway.

• The IPv4 address of the destination host.
