You have started a new role as a solutions architect for an architectural firm that designs large sky scrapers in
the Middle East. Your company hosts large volumes of data and has about 250Tb of data on internal servers.
They have decided to store this data on S3 due to the redundancy offered by it. The company currently has a
telecoms line of 2Mbps connecting their head office to the internet. What method should they use to import this
data on to S3 in the fastest manner possible.
A.
Upload it directly to S3
B.
Purchase and AWS Direct connect and transfer the data over that once it is installed.
C.
AWS Data pipeline
D.
AWS Import/Export
For AWS Import / Export
Maximum device capacity is 16 TB for Amazon Simple Storage Service (Amazon S3) and Amazon EBS jobs.
Maximum device capacity is 4 TB for Amazon Glacier jobs.
So how come AWS Import/Export is an good option to migrate data of 250 TB ?
Answer should be either Snowball or Direct Connect.

Agree! Direct connect is an option so this must be a more favorable answer.

Direct Connect isn’t available in the middle east.

AWS Import/Export allows for the importation of large data sets, using external hard disks which are sent directly to amazon, therefore bypassing the internet” –

“You can create up to 50 jobs per day”. 50 * 16TB = 800 TB per day.

Guys. Using any network connection with 2 Mbps it is not a good answear.
You need 33,5 years to upload this data.
(count to TiB) * (count how many years)
(2/8/1024/1024)*(60*60*24*365*33.5) = 251.87873840331767136000

I think there are tow kinds of AWS Import/Export Services. Snow ball and Import/Export Disk
Import/Export Disk for 16TB and below
Snow ball for bigger data like 50TB/80TB
In this question I think snow ball is better.(snow ball is one of AWS Import/Export service)
So D is correct.
