It supports a 4-byte autonomous system number: BGP on a Tier-0 Gateway supports 4-byte AS (Autonomous System) numbers, which are necessary for larger routing domains.
Can be used as an Exterior Gateway Protocol: BGP is commonly used as an Exterior Gateway Protocol to establish routing between different autonomous systems (AS).
BGP is enabled by default: On a Tier-0 Gateway, BGP is typically enabled by default, allowing administrators to configure it for external routing.

BGP being enabled by default is definitely true!

Logical areas? That's more of an OSPF thing, right?

Totally agree, it's also an Exterior Gateway Protocol.

BGP supports 4-byte AS numbers, that's a fact!

Wait, EIGRP is disabled by default? Didn't know that!

I vaguely recall something about BGP being enabled by default, so maybe E is correct too.

I practiced a question similar to this, and I think EIGRP being disabled by default could be a trick option.

I'm not too sure about the 4-byte AS number, but I feel like it might be relevant to BGP.

I remember BGP being an Exterior Gateway Protocol, so I think option B is definitely one of the answers.

This is a good question to test our understanding of BGP and how it's implemented in the Tier-0 Gateway context. I'll methodically go through each option and think about which ones are most relevant.

The BGP protocol itself is pretty straightforward, but I'm a little fuzzy on the specific Tier-0 Gateway configuration details. I'll review my notes and try to eliminate the options that don't seem to fit.

Okay, let's see. I know BGP is enabled by default on Tier-0 Gateways, so that's an easy one. The 4-byte AS number also sounds familiar. I'll double-check the other options to make sure I have the right three.

Hmm, I'm a bit unsure about the areas and EIGRP parts. I'll have to think through those more carefully to make sure I understand how they relate to BGP configuration.

I'm pretty confident about this one. BGP is an Exterior Gateway Protocol, so that's definitely one of the correct answers. The 4-byte AS number is also a key BGP feature.

This is a tricky one! I'm not sure about the areas and EIGRP part, but A, B, and E sound right to me.

I agree with A, B, and E. The 4-byte AS number support is a key feature of BGP, and Tier-0 Gateways are all about external connectivity.

A and B are essential for BGP. E makes sense too.

A, B, and E seem correct. Tier-0 Gateways definitely use BGP as an Exterior Gateway Protocol, and BGP is enabled by default.
SH

That's right. BGP supports a 4-byte autonomous system number, making option A correct.
VA

A, B, and E are correct. Tier-0 Gateways use BGP as an Exterior Gateway Protocol and have it enabled by default.
