A manufacturing company needs to move data to Azure from multiple locations within three weeks. The main datacenter holds 700 TB of file data. Twelve branch offices each have about 5 TB of file data. Internet bandwidth to all sites is limited and unreliable; an offline transfer is required. Which two actions should you recommend?

The main datacenter's 700 TB requires high-capacity offline transfer. An Azure Data Box Heavy has a usable capacity of 770 TB, making two sequential loads (one device at a time) appropriate for the 700 TB. The 12 branch offices, each with 5 TB, benefit from the Azure Data Box Disk, which offers 8 TB per disk and can be ordered in kits up to 40 TB, allowing efficient collection of the smaller datasets. The limited and unreliable internet bandwidth makes offline transfer methods like Data Box Heavy and Data Box Disk essential. Using a 100-TB Azure Data Box for each branch office is overkill and inefficient for 5 TB datasets. Deploying Azure Data Box Gateway VMs is unsuitable as it relies on online streaming, which is explicitly ruled out by the limited bandwidth. Shipping customer-owned SATA drives via Azure Import/Export is a viable option for large data, but Data Box Heavy offers a more streamlined, managed solution for such a large volume, especially given the time constraint.
