Exam N10-008 topic 1 question 66 discussion

B. BGP (Border Gateway Protocol) is the correct answer as it is used to exchange route information between public autonomous systems. A. OSPF (Open Shortest Path First) is a routing protocol used within a single autonomous system, typically in an enterprise network. It is not used to exchange route information between public autonomous systems. C. EIGRP (Enhanced Interior Gateway Routing Protocol) is a proprietary routing protocol developed by Cisco Systems. It is used within a single autonomous system, typically in enterprise networks. D. RIP (Routing Information Protocol) is a distance-vector routing protocol that is used in small and medium-sized networks. It is not suitable for use in large public autonomous systems.

BGP (Border Gateway Protocol) A path vector routing protocol used by ISPs to establish routing between one another. BGP depends on the concept of Autonomous Systems (ASes).

In networking, an Autonomous System (AS) refers to a collection of connected network infrastructure, such as routers and switches, under a common administrative domain. An AS is typically managed by a single entity, such as an Internet Service Provider (ISP), and is identified by a unique number called an Autonomous System Number (ASN). ASs are essential components of the Internet infrastructure, as they allow for efficient routing of network traffic between different networks. When a packet of data is sent across the Internet, it may need to traverse multiple ASs to reach its destination. Each AS is responsible for making routing decisions for the traffic it handles, based on its own internal policies and external routing protocols such as Border Gateway Protocol (BGP). - chatgpt

Thi should be BGP (Boarder Gateway Protocol) as it is the only EXTERNAL form of routing in the options and they specified PUBLIC network. Anything external is public.

The Internet is based on the AS concept; therefore, two types of routing protocols are required: Interior Gateway Protocols (IGP): Used for routing within an AS. It is also referred to as intra-AS routing. Companies, organizations, and even service providers use an IGP on their internal networks. IGPs include RIP, EIGRP, OSPF, and IS-IS. Exterior Gateway Protocols (EGP): Used for routing between autonomous systems. It is also referred to as inter-AS routing. Service providers and large companies may interconnect using an EGP. The Border Gateway Protocol (BGP) is the only currently viable EGP and is the official routing protocol used by the Internet.

The answer is right! First, you need to understand what an Administrative Distance is.

The answer to this question is wrong. Enhanced Interior Gateway Routing Protocol (EIGRP) is an advanced distance-vector routing protocol that is used on a computer network for automating routing decisions and configuration. The protocol was designed by Cisco Systems as a proprietary protocol, available only on Cisco routers.
