Correct Answer for the Question – What information can be used by a router running a link-state protocol to build and maintain its topological database? is given below

What information can be used by a router running a link-state protocol to build and maintain its topological database? (Choose two.)Reference 1:http://www.ciscopress.com/articles/article.asp?p=24090&seqNum=4Link state protocols, sometimes called shortest path first or distributed database protocols, are built around a well-known algorithm from graph theory, E. W. Dijkstra’a shortest path algorithm. Examples of link state routing protocols are:Open Shortest Path First (OSPF) for IPThe ISO’s Intermediate System to Intermediate System (IS-IS) for CLNS and IPDEC’s DNA Phase VNovell’s NetWare Link Services Protocol (NLSP)Although link state protocols are rightly considered more complex than distance vector protocols, the basic functionality is not complex at all:1. Each router establishes a relationship—an adjacency—with each of its neighbors.2. Each router sends link state advertisements (LSAs), some3. Each router stores a copy of all the LSAs it has seen in a database. If all works well, the databases in all routers should be identical.4. The completed topological database, also called the link state database, describes a graph of the internetwork. Using the Dijkstra algorithm, each router calculates the shortest path to each network and enters this information into the route table.OSPF Tutorial

hello packets

SAP messages sent by other routers

LSAs from other routers

beacons received on point-to-point links

routing tables received from other link-state routers

TTL packets from designated routers

Correct Answer

The Correct Answer for this Question is

hello packets
LSAs from other routers
