Wrong or outdated question on Snowball Edge

[rodrigo-2]

Hello.

There is a question about snowball that I believe has a wrong or outdated answer.
The question is:

“You are working as a Solutions Architect for a global IT services company which has over a hundred data centers all around the globe. Due to financial constraints, one of its data centers located in Detroit will be decommissioned soon and they require its entire data to be moved to their cloud infrastructure in AWS. They need to migrate a total of 80 TB of data strictly in 1 week to avoid further system downtime. In addition, they only have a limited 25 Mbps Internet line in their data center to do the migration. In this scenario, what is the fastest and most cost-effective solution to use to migrate all of the data to AWS?”

Between the answers, there is “Use snowball…”, and also, “Use snowball edge”. I answered snowball, but the questions says that the right one is use Edge:

“Since the total amount of data that need to be migrated is 80 TB, you cannot use the regular AWS Snowball. Instead, use the Snowball Edge which has an 80 TB of usable capacity. Hence, the correct answer here is to use the AWS Snowball Edge service to migrate the 80 TB of data to AWS.”

Maybe that is a outdated data? Did aws change the amount for snowball services?
Because here it says different:

Hi Rodrigo,

I think you missed the provided rationale as to why Snowball is incorrect. It’s already mentioned in the explanation that:

Using the AWS Snowball service to migrate the 80 TB of data to AWS is incorrect since the total amount of data that need to be migrated is 80 TB which is over the 72 TB usable capacity limit of Snowball. Take note that although Snowball has two types of device model: 50 TB and 80 TB, you can only store a total of 42 TB and 72 TB respectively based on their usable capacity limits. You have to use AWS Snowball Edge instead.

A Snowball 80 TB device only has a 72 TB of usable space, and not exactly 80 TB. This is clearly mentioned in the explanation as well as in the provided reference link:
