Answer: Create an AWS Snowball Edge job. Receive a Snowball Edge device on premises. Use the Snowball Edge client to transfer data to the device. Return the device so that AWS can import the data into Amazon S3.
## Explanation **Correct Answer: B - AWS Snowball Edge** **Why Option B is correct:** 1. **70 TB of data** - This is a large amount of data (70 TB = 70,000 GB) 2. **"as soon as possible while using the least possible network bandwidth"** - This is the key requirement 3. **Snowball Edge** is specifically designed for large-scale data transfers when network bandwidth is limited or expensive 4. **Physical data transfer** avoids using internet bandwidth entirely 5. **Faster than internet transfer** - Even with high-speed internet, transferring 70 TB would take days or weeks **Why other options are incorrect:** **Option A (AWS CLI):** - Would require transferring 70 TB over the internet - Would consume massive network bandwidth - Would be very slow (could take weeks) - Does not meet "least possible network bandwidth" requirement **Option C (S3 File Gateway with public endpoint):** - Still transfers data over internet - Uses significant network bandwidth - Slower than Snowball for large datasets **Option D (S3 File Gateway with Direct Connect):** - Direct Connect provides dedicated network connection - Still uses network bandwidth (though more reliable) - More expensive and complex setup - Not the fastest option for 70 TB **Key AWS Services for Data Migration:** - **AWS Snowball/Snowball Edge**: Physical data transfer devices for large datasets - **AWS DataSync**: Network-based transfer with optimization - **AWS Transfer Family**: For specific protocols (SFTP, FTPS, FTP) - **AWS Storage Gateway**: For hybrid storage solutions For this scenario with 70 TB of data and the requirement to minimize network bandwidth, Snowball Edge is the optimal solution.

A company uses NFS to store large video files in on-premises network attached storage. Each video file ranges in size from 1 MB to 500 GB. The total storage is 70 TB and is no longer growing. The company decides to migrate the video files to Amazon S3. The company must migrate the video files as soon as possible while using the least possible network bandwidth. Which solution will meet these requirements?
A
Create an S3 bucket. Create an IAM role that has permissions to write to the S3 bucket. Use the AWS CLI to copy all files locally to the S3 bucket.
B
Create an AWS Snowball Edge job. Receive a Snowball Edge device on premises. Use the Snowball Edge client to transfer data to the device. Return the device so that AWS can import the data into Amazon S3.
C
Deploy an S3 File Gateway on premises. Create a public service endpoint to connect to the S3 File Gateway. Create an S3 bucket. Create a new NFS file share on the S3 File Gateway. Point the new file share to the S3 bucket. Transfer the data from the existing NFS file share to the S3 File Gateway.
D
Set up an AWS Direct Connect connection between the on-premises network and AWS. Deploy an S3 File Gateway on premises. Create a public virtual interface (VIF) to connect to the S3 File Gateway. Create an S3 bucket. Create a new NFS file share on the S3 File Gateway. Point the new file share to the S3 bucket. Transfer the data from the existing NFS file share to the S3 File Gateway.
