wrong answer about Transit Gateway?

[cdt78]

Hello, for the question below:

A company has a hybrid network architecture that consists of multiple regional on-premises data centers and hundreds of AWS VPCs in various AWS Regions. The Network Administrator has been tasked to connect all of the company’s VPCs, on-premises networks, and VPN connections into a single gateway. The solution should also support inter-region peering across multiple AWS regions.
What’s the MOST suitable solution that the Administrator should implement to build the requested network architecture?

the correct answer and the explanation showed is

Launch an AWS Transit Gateway to connect the geographically disperse VPCs and remote networks in order to create a global network transit center

which I believe is incorrect

TG gateway is a regional service. You will need one TG in each Region to be able to attach VPCs from that respective region to the TG.

One could build a topology with peering between TGs but that would contradict the requirement for a single gateway object.

Hello cdt78,

Thanks for your feedback.

I see. point taken. The correct answer was meant to be more of a “Use this X service to achieve this..” case. I think that the part where it says “Launch an AWS Transit Gateway.” gives a different context to what we’re trying to convey as it implies creating a single GW resource when in fact the solution involves multiple transit gws. We’ll revise the correct option for this item.

Please let me know if you have any further questions.
