What are two link-state routing protocols? (Choose two.)
IS-IS (Intermediate System to Intermediate System) and OSPF (Open Shortest Path First) are both link-state routing protocols. These protocols are used to determine the optimal path for data to travel across a network by building a complete map of the network's topology. RIP (Routing Information Protocol) is a distance-vector routing protocol, and BGP (Border Gateway Protocol) is a path-vector protocol, neither of which are link-state protocols.
The two link-state routing protocols are: B. IS-IS (Intermediate System to Intermediate System) - IS-IS is a link-state routing protocol that is used to move information efficiently within a computer network, a group of physically connected computers or similar devices. D. OSPF (Open Shortest Path First) - OSPF is another link-state routing protocol that is widely used in IP networks. It uses the Shortest Path First (SPF) algorithm to calculate the shortest path to each node. Explanation of Other Options: - A. RIP (Routing Information Protocol): RIP is a distance-vector routing protocol, not a link-state routing protocol. It uses hop count as the metric for path selection. - C. BGP (Border Gateway Protocol): BGP is a path-vector protocol used primarily for inter-domain routing on the internet. It is not a link-state protocol.
