What devices transfer packet across multiply network and use tables to store address to determine to best destination?
Routers
Which layer of the osi model always provides the address of a packet's final destination?
Network - Always identifies the final destination of a packet
What is used to reassemble the packets in the correct order at the destination device in a packet-switched data network?
In a packet-switched data network, what is used to reassemble the packets in the correct order at the destination device?
What are true statements about routes and their use?
--> If the destination network is directly connected, the router forwards the packet to the destination host. --> If no route exists for the destination network and a default route is present, the packet is forwarded to the next-hop router. --> If the originating host has a default gateway configured, the packet for a remote network can be forwarded using that route.
2 How do routers use the routing table to determine the best path to a destination network?
They check the number of hops a packet passes to reach the the destination. The router then uses the route with least number of Hops.
When forwarding a packet which route will the packet select?
First, routing is the process a router performs when making forwarding decisions for each packet arriving at the gateway interface. To forward a packet to a destination network, the router requires a route to that network. If a route to a destination network does not exist on the router, the packet will be forwarded to the default gateway. Now, the destination network can be a number of routers or hops away from the default gateway. If the router has an entry for the network in its routing table, it would only indicate the next-hop router to which the packet is to be forwarded to and not the exact route to the final router. To sum it up, the routing process uses a routing table to map the destination address to the next hop and then forwards the packet to the next-hop address.
Why is it that an ICMP packet does not have source and destination port?
Because ICMP is on the network layer
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.
Firewall is a router that examines the header of every packet of data it receives to determine whether that type of packet is authorized to continue to its destination?
packet-filtering
Which operation is used by a router to extract the destination network address from the destination IP address of a packet?
Route table lookup
At which OSI layer does a computer determine if the packet is intended for it on a 10BaseT Network?
The Network Layer
What is the process of deep packet inspection?
Deep packet inspection is a type of computer network packet filtering. Deep packet inspection examines the data part of a package as it passes through an inspection point. Factors such as viruses, spam, and intrusions determine whether the packet passes or needs to be rerouted to a different destination. Sometimes the packet is rerouted for the collection of statistical purposes.
