A company has 150 TB of archived image data stored on-premises that needs to be moved to the AWS Cloud within the next month. The company's current network connection allows up to 100 Mbps uploads for this purpose during the night only.
What is the MOST cost-effective mechanism to move this data and meet the migration deadline?
To move 150 TB of archived image data within a month, AWS Snowball is the most cost-effective and practical solution. AWS Snowball is designed for transferring large amounts of data in a secure and efficient manner. Given the limited network bandwidth of 100 Mbps during the night, transferring this amount of data over the network would take too long. AWS Snowmobile, on the other hand, is designed for exabyte-scale data transfers and would be excessive for this requirement. Therefore, ordering multiple AWS Snowball devices is the best option to ensure the data is moved within the deadline.
Couple of snowball devices (80 TB) should able to move 150 TB easily. So answer should be B.
Its B.Snowball devices (marked correct) eg.6 hrs night 6 hrs*60min/hr=360 min 360 min*60 sec/min=21600 sec 100 Mbps*21600 s=2160000Mb or 2160 Gb or 2.1 TB can only be done So,for 150 TB, we can use 2 X Snowball Edge Storage Optimised devices. Size of Snowball Edge Storage Optimised device=80 TB Size of Snowball Edge Compute Optimised device= 40 TB Size of Snowcone =8 TB Size of Snowmobile =100 PB (1 PB=1000 TB)

Passed the exam on 26th June, this question was on my test.
B From AWS faqs Q: How should I choose between Snowmobile and Snowball? To migrate large datasets of 10PB or more in a single location, you should use Snowmobile. For datasets less than 10PB or distributed in multiple locations, you should use Snowball. In addition, you should evaluate the amount of available bandwidth in your network backbone. If you have a high speed backbone with hundreds of Gb/s of spare throughput, then you can use Snowmobile to migrate the large datasets all at once. If you have limited bandwidth on your backbone, you should consider using multiple Snowballs to migrate the data incrementally.
Passed the exam on 19th June 2021. This question appeared in my exam. Marking it for future help.
B is correct
150TB * 8 =1200Tbs 1200*1024*1024 =1258291200 total mbs 100mbps*3600(second per hour) * 16(hour per day for transfer) * 30(days) = 10800000 mbs it's not enough time to transfer via network. B is only choice.
B right
Answer B 1 Gbps connection can transfer 10TB data in one day, here we have 100Mbs line, that can be used during nights only for data transfer.

BBB 150TB in month -> SnowBall
One Snowmobile can transport up to one hundred petabytes of data in a single trip, the equivalent of using about 1,250 AWS Snowball devices.
Snowmobile works on Petabyte scale. One 80 TB Snowball has 72 TB capacity, for this 150 TB you will need 2 x 80TB and 1 x 40 TB = a total 3 snowball. Ans is B.
it's B
Snowball mobile works at petabyte scale, so maynot be needed. B for sure
100% is B
S3TA takes months...
