Actual exam question for Ericsson's ECP-206 exam

Question #: 35
Topic #: 5

Which statement accurately defines an Autonomous System (AS)?

AAn AS is a set of routers under a single administration, using an interior gateway protocol and common metrics to route packets within the AS.

BAn AS is a group of networks directly connected to each other that can distribute eBGP information using directly established links.

CAn AS is a network that is capable of autonomously forwarding packets, regardless of direct or indirect connectivity to the Internet.

DAn AS is a collection of IS-IS routes imported into BGP and presented in such a way that networks connected to the AS have a global overview of the network.

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'm going with Option A. The description of routers under a single administration, using a common protocol and metrics, really captures the essence of an Autonomous System.

Option A seems to be the most accurate definition of an Autonomous System. The key aspects of an AS are the single administration, use of an interior gateway protocol, and common metrics for routing within the AS.
