Question #: 38
Topic #: 3

Which two statements are true about link-state routing protocols? (Choose two.)

AThe advertisement exchange is mainly triggered by a change in the network.

BEach router uses a reliable update mechanism to exchange topology information with its neighbors.
C Link-state routing protocols mainly use hop-counts to determine the link cost

DA distance vector algorithm is very processor intensive compared to Dijkstra's algorithm.

Show Suggested Answer

Suggested Answer: A

The statement that accurately defines an Autonomous System (AS) is that an AS is a set of routers under a single administration, using an interior gateway protocol and common metrics to route packets within the AS. An AS is a logical grouping of networks that share a common routing policy and operate under a single administrative authority. An AS can be a single network or a collection of networks that are interconnected by routers. An AS uses an interior gateway protocol (IGP), such as OSPF or IS-IS, to exchange routing information within the AS. An IGP uses common metrics, such as hop count or bandwidth, to determine the best path to each destination within the AS. An AS also has a unique number assigned by IANA, called an AS number (ASN), which identifies the AS in interdomain routing .

I think option A is true because link-state protocols are triggered by network changes.
