Ericsson ECP-206 Exam - 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 .

D seems too specific, not sure about that one.

Wait, can an AS really forward packets without any connectivity?

An AS is definitely a set of routers under one admin.

I vaguely recall that eBGP is important for AS communication, so option B might be relevant, but I’m not entirely clear on the specifics of how they connect.

I feel like I’ve seen questions about AS definitions before, and I’m leaning towards option C, but I’m not sure if it really captures the essence of what an AS is.

I think option A sounds familiar because we discussed interior gateway protocols in class, but I’m not completely confident about the details.

I remember studying that an AS is typically managed by a single organization, but I'm not sure if that means it has to use an interior gateway protocol.

This is a tricky one. There are a lot of technical terms and networking concepts involved. I'm going to have to really review my notes and make sure I understand the fundamentals before I can confidently select the right answer.

Okay, I've got a strategy here. I know an Autonomous System is related to how networks are organized and how routing information is shared between them. I'll focus on the details in each option to determine which one best fits that definition.

This question seems pretty straightforward. I think the key is understanding the definition of an Autonomous System and how it relates to routing protocols and network administration.

Hmm, I'm a little unsure about this one. The options seem to be getting at different aspects of an Autonomous System, but I'm not totally confident I can pick the most accurate definition. I'll have to think this through carefully.

Root-cause analysis is usually a solid strategy, but I wonder if there's more to consider with cross-functional teams.

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.
