Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.

Question

Table 1: Router Look-up
Destination Subnet Number Next Hop
111.40.170.0/23
111.40.168.0/23
111.40.166.0/23
111.40.164.0/22
0.0.0.0/0
R1
R2
R3
R4
R5
What route (next hop) will the router select, using the longest prefix match, for each of
the following packet destinations:
• 111.40.171.123
• 111.40.169.19
• 111.40.163.151

Consider the following network. A. Display router forwarding table A. such that all traffic for H3 is transmittedthrough interface 3. b. May you enter a transmission table on router A, in that all traffic from HI to host H3 is transmitted via interface 3, while all traffic from 112 to host H3 is transmitted via interface 42? (Hint: This issue is a trick.)
Q.8) In a large autonomous system (AS) with hundreds of routers, a network administrator is tasked with implementing a routing protocol that can provide the best path selection and also dynamically react to network changes. Which protocol would be the most suitable for an internal large-scale network that requires efficient path selection, fast convergence, and the ability to handle a large number of routers from given options? A) RIP (Routing Information Protocol) B) OSPF (Open Shortest Path First) C) BGP (Border Gateway Protocol) D) EIGRP (Enhanced Interior Gateway Routing Protocol)
