An organization has 45\text{ TB} of data stored on an on-premises network-attached storage… — Microsoft Azure Administrator (AZ-104)

An organization has $45\text{ TB}$ of data stored on an on-premises network-attached storage (NAS) system. The organization needs to migrate this data to an Azure Blob Storage account. The local network has a restricted outbound internet connection, providing only $10\text{ Mbps}$ of dedicated bandwidth for the migration. The migration must be completed within $30\text{ days}$ . The organization's security policy strictly prohibits the shipment of customer-owned physical drives and requires that all data copied to temporary physical transport media be accessible directly via standard network protocols (SMB or NFS) without requiring staging hosts. Which migration solution should you recommend to meet these requirements?

A single Azure Data Box deviceCevap
B
Five Azure Data Box Disks
C
An Azure Import/Export job using customer-provided drives
D
A single Azure Data Box Heavy device

Cevap

A single Azure Data Box device

A single Azure Data Box device is the correct choice because the dataset size (

45\text{ TB}

) exceeds the

35\text{ TB}

usable capacity limit of a single Azure Data Box Disk order. Additionally, Data Box supports direct copying over the local network via SMB and NFS protocols directly from the NAS, avoiding the need for staging hosts. Because the hardware is provided by Microsoft, it satisfies the security policy prohibiting customer-owned storage media. Finally, the restricted internet connection makes offline physical transfer the only feasible method within the

30\text{ -day}

window.

Adım Adım Çözüm

Calculate the network transfer time to determine if online migration is possible.

10\text{ Mbps}

connection yields approximately

1.25\text{ MB/s}

. Transferring

45\text{ TB}

would take over

416\text{ days}

, which exceeds the

30\text{ -day}

requirement.

To determine whether to use an online tool (like AzCopy) or an offline physical transfer service.

Filter the offline options based on security policies.

The Azure Import/Export service is eliminated because the organization's policy prohibits shipping customer-owned physical drives.

To ensure compliance with the organization's security and hardware ownership requirements.

Compare the remaining Microsoft-provided offline shipping solutions based on capacity and connectivity requirements.

Azure Data Box Disk is ruled out because it has a

35\text{ TB}

usable capacity limit and requires staging hosts (no native NFS/SMB shares). Azure Data Box Heavy is ruled out because it is designed for datasets over

100\text{ TB}

To identify the most cost-effective and technically compatible device that fits the

45\text{ TB}

dataset and supports direct NFS/SMB access.

Anahtar Kavram

Selecting the appropriate Azure offline data transfer service (Azure Data Box, Data Box Disk, Data Box Heavy, or Azure Import/Export) based on network bandwidth, dataset size, security policies, and protocol compatibility.
