Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 659 discussion

90% utilization of the bandwidth = they discouraged the use of internet bandwidth for uploading, go seek for offline data seeding to AWS method

50 TB of data to AWS within 2 weeks = Snowball Edge Storage Optimized

50 TB of data to AWS within 2 weeks + 90% utilization already be used -> snowball

(B) is correct. Direct Connect is "A dedicated connection [is] made through a 1-Gbps, 10-Gbps, or 100-Gbps Ethernet port dedicated to a single customer." DX uses 802.1Q VLANs providing a dedicated private network connection to AWS. At 1-Gbps, transfer takes less than 5 days; at 100-Gbps it takes less than 67 minutes. Since it's a data center & not an oil rig in the middle of the Gulf of Mexico, data center should be able to get this service. (C) is incorrect "Consider Snowball Edge if you need to run computing in rugged, austere, mobile, or disconnected (or intermittently connected) environments. Also consider it for large-scale data transfers and migrations when bandwidth is not available for use of a high-speed online transfer service, such as AWS DataSync."

Assuming vpn is 1Gbps, it can still transfer 50TB with in 5days with only 10% bandwidth avaliable

A DataSync is for data B Direct connect takes longer than 2 weeks D StorageGateway is useless without more contex C is only remaining choice.

Not memtioned network bandwidth. How we know that?
