Question ID 6374	A workstation has just resolved a browser URL to the IP address of a server. What protocol will the workstation now use to determine the destination MAC address to be placed into frames directed toward the server?
Option A	HTTP
Option B	. DNS
Option C	DHCP
Option D	RARP
Option E	ARP
Correct Answer	e

Explanation The RARP protocol is used to translate hardware interface addresses to protocol addresses. The RARP message format is very similar to the ARPformat. When the booting computer sends the broadcast ARP request, it places its own hardware address in both the sending and receiving fields in the encapsulated ARP data packet. The RARP server will fill in the correct sending and receiving IP addresses in its response to the message. This way thebooting computer will know its IP address when it gets the message from the RARP server.

Question ID 6375	What does a host on an Ethernet network do when it is creating a frame and it does not have the destination address?

Option C	Sends a message to the router requesting the address
Option D	Sends out an ARP request with the destination IP address
Correct Answer	d

Explanation In this case, it will send out an ARP request for MAC address of the destination IP (assuming it doesn't already have it in its table) and then address it to the destination's MAC address.
