What are three examples of dynamic IGPs? (Choose three.)

The correct answer is A. OSPF C. IS-IS E. RIP. Dynamic Interior Gateway Protocols (IGPs) are routing protocols used within an autonomous system to automatically discover and exchange routing information. OSPF, IS-IS, and RIP are all examples of such protocols.

Why each option

Dynamic Interior Gateway Protocols (IGPs) are routing protocols used within an autonomous system to automatically discover and exchange routing information. OSPF, IS-IS, and RIP are all examples of such protocols.

AOSPFCorrect

OSPF (Open Shortest Path First) is a link-state dynamic IGP widely used in enterprise networks.

BBGP

BGP (Border Gateway Protocol) is an Exterior Gateway Protocol (EGP), not an IGP, used for routing between autonomous systems.

CIS-ISCorrect

IS-IS (Intermediate System to Intermediate System) is another link-state dynamic IGP, commonly used by service providers.

DPIM

PIM (Protocol Independent Multicast) is a multicast routing protocol, not a unicast IGP.

ERIPCorrect

RIP (Routing Information Protocol) is a distance-vector dynamic IGP, known for its simplicity and use in smaller networks.
