Establish a 10 Gbps AWS Direct Connect and use AWS DataSync.

Order multiple AWS Snowball Edge Storage Optimized devices to transfer the data offline.

Use AWS Storage Gateway Volume Gateway to cache the data to S3.

Full Answer

C.Order multiple AWS Snowball Edge Storage Optimized devices to transfer the data offline.✓ Correct

Order multiple AWS Snowball Edge Storage Optimized devices to transfer the data offline.

For petabyte-scale data transfers where network bandwidth is insufficient (10 PB over 1 Gbps takes years), offline transfer using the AWS Snow Family (Snowball Edge or Snowmobile) is the only feasible solution.

Common mistakes

Overestimating network transfer speeds for petabyte-scale data.
