What Two Tasks Do Dynamic Routing Protocols Perform? (Choose Two.)

 What two tasks do dynamic routing protocols perform? (Choose two.)

• Hosts discovery.
• Manage and update the routing tales.
• Network discovery.
• IP address allocation.
• Propagation of the host default gateway.

Answer: Management and the updating routing table, network discovery is the two tasks that are performed by the dynamic routing table.   

Dynamic routing protocols

The dynamic routing protocol in the router exchanges the update on the network status with themselves continuously such as the broadcast or the multicast. Along with routing modification messages by protocols, the router can update the routing table if any change in the network topology happens ever.

Moreover, dynamic routing is the technique of the network which provides the routing optimal data. Dynamic routing uses various protocols and algorithms. The common is RIP (routing information protocol) and the OSPF (open shortest path first). the protocols of the dynamic routing permit the router to share the information with another router which helps them to select the best possible path. Some of the protocol’s examples are RIP, EIGRP (interior gateway routing protocol), and OSPF.

The routing protocol has three basic types which are discussed in the following:

Distance-vector Routing protocols: 

This type of routing protocol uses the easiest algorithm which can calculate a cumulative distance between routers based on hop count. For example, RIPv1 and the IGRP.

Link state routing protocols: 

It uses the most advanced algorithm which works to manage the difficult database of the internetwork topology. an example is OSPF and IS-IS (intermediate system to intermediate system).

Hybrid routing protocols:

It uses the combo of distance-vector and the link-state method which can incorporate the benefits and lessen the cons. an example is EIGRP and the RIPV2 (routing information protocols version 2)
