C A: This will be too slow. B: Direct connect takes too long to provision. C: Because the question did not state what is the bandwidth of the company, using Snowball to transfer 70TB make sense. D: While this is possible, we do not know If the server is physical or virtual and SMS just migrate it does not upgrade. Wherelse in C you can immediately select the best AMI to start and rely on Snowball to transfer the data.

Agree with Ans C. But all the reasons provided here doesn't sound right. The key part of the question is: "Which is the FASTEST and MOST cost-effective way to perform the migration?" A: First of all, you cannot convert a physical server to a virtual server. You have to create a new VM and migrate the applications and data. Because the question did not state what is the bandwidth, it is difficult to calculate how long it will take to transfer data. B: Reasons same as A plus it will take significant amount of time to provision DX C: Seems to be the most reasonable solution. D: SMS cannot migrate a physical server. On top of that Because the question did not state what is the bandwidth, it is difficult to calculate how long it will take to transfer data.

I do support answer "C". The snowball is the FASTEST option for transfer (next business day for delivery).

Without knowing local bandwidth, you can't determine whether snowball is faster or not. The problem is with the question. 70TB may take a long time to transfer, but it may not.
