Exam AWS Certified Solutions Architect - Professional topic 1 question 819 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional
Question #: 819
Topic #: 1
[All AWS Certified Solutions Architect - Professional Questions]

A video processing company wants to build a machine learning (ML) model by using 600 TB of compressed data that is stored as thousands of files in the company's on-premises network attached storage system. The company does not have the necessary compute resources on premises for ML experiments and wants to use AWS.
The company needs to complete the data transfer to AWS within 3 weeks. The data transfer will be a one-time transfer. The data must be encrypted in transit. The measured upload speed of the company's internet connection is 100 Mbps, and multiple departments share the connection.
Which solution will meet these requirements MOST cost-effectively?

  • A. Order several AWS Snowball Edge Storage Optimized devices by using the AWS Management Console. Configure the devices with a destination S3 bucket. Copy the data to the devices. Ship the devices back to AWS.
  • B. Set up a 10 Gbps AWS Direct Connect connection between the company location and the nearest AWS Region. Transfer the data over a VPN connection into the Region to store the data in Amazon S3.
  • C. Create a VPN connection between the on-premises network storage and the nearest AWS Region. Transfer the data over the VPN connection.
  • D. Deploy an AWS Storage Gateway file gateway on premises. Configure the file gateway with a destination S3 bucket. Copy the data to the file gateway.

Snowball edge has 80 TB of usable HDD storage. We need at least 8 of these to transfer 600 TB data. Based on the pricing here https://aws.amazon.com/snowball/pricing/ for each snowball device, it will not come cheap. Transferring 60 TB or 600,000GB of data via a 10Gbps connection will only take around 60,000 secs, 1,000 mins or approx 16.7 hours. I think a 1 month 10Gbps connection will be much much cheaper than Snowball.

The company needs to complete the data transfer to AWS within 3 weeks and the measured upload speed of the company's internet connection is 100 Mbps: 100 Mbps = 12.5 MB/s --> 12.5x60x60x24 = 1080000 MB In one day, it transfers 1,08 TB. In 3 weeks, it transfers only 7x3x1.08=22.68 TB! So the answer is A.
