Ericsson Exam ECP-206 Topic 7 Question 26 Discussion

Actual exam question for Ericsson's ECP-206 exam

Question #: 26
Topic #: 7

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.

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 .

Hmm, that does make sense too. It's a tough question.

D) Mixing IS-IS and BGP? That's like trying to put a square peg in a round hole. Not the right definition for an AS.

I'm leaning towards B, as it talks about directly connected networks.

C) Haha, this one's a bit too autonomous if you ask me. An AS still needs to be connected to the broader internet in some way.

But A makes sense because it mentions routers and common metrics.

B) No, that's not quite right. eBGP is for connecting to other ASes, not routing within a single AS.
