Exam AWS Certified Solutions Architect - Associate SAA-C02 topic 1 question 89 discussion

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)

S3TA takes months...

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 is correct

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.

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.

100% is B

Snowball mobile works at petabyte scale, so maynot be needed. B for sure

it's B

B right

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.

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.

BBB 150TB in month -> SnowBall
