How do you calculate metrics?
Hop count & administrative distance. This is a measure used by the routing protocol to calculate the best path to a given destination, if it learns multiple paths to the same destination. Each routing protocol uses a different metric.
Which routing protocol depends on the DUAL algorithm to calculate the shortest path to a destination?

What is data unit formation techniques in osi reference model?
Layer N in the model accepts data from the next higher layer, layer N+1, in the form of a block of data known as a service data unit (SDU). To deliver this SDU to the destination system, a layer N protocol is used between the layer N entity in the source system and the layer N entity in the destination system. The source protocol entity encapsulates the SDU by adding a header and possibly a trailer, containing protocol control information, such as source and destination address and error check codes. The SDU plus header and trailer is known as a protocol data unit (PDU). An SDU may be broken up into multiple chunks and sent out in multiple PDUs, or multiple SDUs may be aggregated and send out in a single PDU, if the protocol allows it.
What is protocol data unit?
data reassembled at the destination =))
Which protocol enables a host to determine a destination mac address for a given destination ip address?
DHCP
What is potocol?
protocol is a connection establishment between the source computer to destination computer ex: tcp / ip protocol
What is an Internet destination?
Internet destination refers to the location that a process is aimed to get to. This part of the internet control message protocol with the destination expected to decode the message.
Routes packets through the internet to get them to their destination?
IP (Internet Protocol)
How is data passed in packets?
The details vary enormously from protocol to protocol, but the basics are the same for all of them. A stream of data is split into packets, the packet has a header which contains (amongst other things) the destination for the packet. The network uses the destination address to deliver the network to the correct destination.
Is protocol needed for every transmission?
Yes protocol is need for every transmission so that any trasmitted data can surely reach to there destination.........
What is the primary weakness in the icmp protocol that makes it subject to attack?
the primary weakness in the ICMP protocol is that, it does provide authentication to verify the destination address.
Which protocol would you select if you where looking for a protocol that supports multiple upper layer protocols and is a RFC standard?
Point-to-Point Protocol.
