Migrating 70 TB On-Premises NFS Data to Amazon S3
Determine high-performing and/or scalable storage solutions.
Design scalable and loosely coupled architectures.
Answer
Correct answer: B — Create an AWS Snowball Edge job to physically transfer the 70 TB of video files on-premises and have AWS import them into S3, avoiding network bandwidth usage entirely.
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?
Community Insight
The key constraints are migrating 70 TB as fast as possible with the least network bandwidth; the common trap is choosing an S3 File Gateway approach that still pushes all 70 TB over the network, or failing to account for Direct Connect provisioning delays of 1–2 months.
This question tests choosing the optimal data migration method to Amazon S3 for 70 TB of static video files when speed and minimal network bandwidth are required. AWS Snowball Edge is the correct answer because it physically transports data off-premises, avoiding network bandwidth entirely.
Choosing option C (S3 File Gateway with a public endpoint) or option D (Direct Connect with S3 File Gateway). Learners often think File Gateway avoids network usage, but it still transfers all 70 TB over the network. Option D adds weeks of Direct Connect provisioning time, failing the 'as soon as possible' requirement.

The solution that meets the requirements of migrating 70 TB of large video files as quickly as possible and with the least possible bandwidth is to create an AWS Snowball Edge job, transfer the data to the device locally, and then return the device to AWS for import into Amazon S3. This method avoids intensive use of the internet network for the massive data transfer.

AWS Snowball Edge is specifically designed for scenarios requiring the transfer of large datasets (terabytes or petabytes) with minimal network bandwidth usage. It is ideal for one-time, large-scale migrations like the 70 TB of video files in this case. For ongoing, smaller-scale data transfers, solutions like S3 File Gateway or AWS DataSync may be more appropriate.

Let's analyse this: B. On a Snowball Edge device you can copy files with a speed of up to 100Gbps. 70TB will take around 5600 seconds, so very quickly, less than 2 hours. The downside is that it'll take between 4-6 working days to receive the device and then another 2-3 working days to send it back and for AWS to move the data onto S3 once it reaches them. Total time: 6-9 working days. Bandwidth used: 0. C. File Gateway uses the Internet, so maximum speed will be at most 1Gbps, so it'll take a minimum of 6.5 days and you use 70TB of Internet bandwidth. D. You can achieve speeds of up to 10Gbps with Direct Connect. Total time 15.5 hours and you will use 70TB of bandwidth. However, what's interesting is that the question does not specific what type of bandwidth? Direct Connect does not use your Internet bandwidth, as you will have a dedicate peer to peer connectivity between your on-prem and the AWS Cloud, so technically, you're not using your "public" bandwidth. The requirements are a bit too vague but I think that B is the most appropriate answer, although D might also be correct if the bandwidth usage refers strictly to your public connectivity.

Option A involves creating an S3 bucket, creating an IAM role with permissions to write to the bucket, and using the AWS CLI to copy all files locally to the S3 bucket. This option would not be the most efficient solution, as it would require transferring the data over the network, which could be slow and may not use the least possible network bandwidth. Option C involves deploying an S3 File Gateway on premises, creating a public service endpoint to connect to the S3 File Gateway, creating an S3 bucket, and transferring the data from the existing NFS file share to the S3 File Gateway. This option would not be the most efficient solution, as it would require transferring the data over the network, which could be slow and may not use the least possible network bandwidth.

The question states that the storage is no longer growing. This implies that we don’t need to make any kind of data synchronization. Additionally, the total storage is 70 TB, which is a large amount of data. This implies high transfer costs. So, we can discard A, C and D options. Correct option: A. A Snowball device is a physical storage device which supports large data transfers. It is commonly used for transporting huge amounts of data from on-premises to AWS. Concretely, Snowball Edge is suitable for data transfers up to 80 TB. The transport times are between 1 and 2 weeks, so in case that we have hundreds of terabytes of data, we get them earlier than using Internet. In case that we need to transfer petabytes of data, it is recommended to use AWS Snowmobile, which is a physical track that transports data, up to 10 PB.

Select answer: B Why? The essence of the S3 File Gateway is to provide a seamless interface for on-premises apps to store and retrieve data in Amazon S3 using standard protocols such as NFS and SMB. On the other hand, As I write this, the first AWS Official use case for Snowball is to migrate data especially when network conditions are limited. The question is a bit tricky. But applying simple logical linguistic analysis, "as soon as possible" coupled with "the least network bandwidth possible" means the question's focal point is network bandwidth. So, whatever the least network bandwidth is, it`s corresponding time to get the data into AWS S3 bucket is the value for "as soon as possible".

Given the requirement to migrate the video files to Amazon S3 as soon as possible while using the least possible network bandwidth, the most suitable solution would be: 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. This solution involves physically transferring the data using a Snowball Edge device, which can handle large volumes of data with high-speed transfers while minimizing the impact on the network. It is particularly useful when dealing with large files and a significant amount of data. Additionally, it ensures secure transfer and efficient migration to Amazon S3.

"Least possible bandwidth" = Snowball Edge as it's physically transported to AWS and doesn't use any bandwidth. Depending on the company's available bandwidth (that we should not use anyway) it would still be faster and A and C.

Correct answer is C. The key words are NFS, S3 and low bandwidth. S3 File Gateway retains access through NFS protocol so that existing users don't have to change anything while being able to use S3 to store the files. The question also gives a clue that we only need to upload existing 70TB and no new data is added. This gives a clue that users only need to read data via NFS and don't need to write to S3 bucket. The existing data can be quickly uploaded (via endpoint) to S3 bucket by admin.

Guru4Cloud

Selected: B
Option B is the correct solution to meet the requirements. The reasons are: AWS Snowball Edge provides a physical storage device to transfer large local datasets to Amazon S3. This avoids using network bandwidth for the data transfer. Snowball Edge can transfer up to 80TB per device, so a single Snowball Edge job can handle the 70TB dataset. The client transfers data to the Snowball Edge device on-premises, avoiding the need to copy the data over the network. When AWS receives the device back, the data is imported to the S3 bucket. This achieves fast data migration without using network bandwidth. Option A would consume large amounts of network bandwidth for the data transfer. Options C and D use S3 File Gateway, which still requires the data to be sent over the network to S3. This does not meet the goal of minimizing network bandwidth. So Option B with Snowball Edge is the right approach to migrate the large dataset quickly while using minimal network bandwidth.
Nazmul123

The Snowball Edge device can transfer data at up to 100 Gbps, which is much faster than the company's current network bandwidth. The Snowball Edge device is also a secure way to transfer data, as it is encrypted at rest and in transit.

Option D: It would also involve network transfers. Although it provides a dedicated network connection, it doesn't address the requirement of minimizing network bandwidth usage. Option B: It is the most suitable solution in this scenario. With Snowball Edge, a physical device is sent to the company's premises. The large video files can be directly transferred to the Snowball Edge device, bypassing the need for significant network transfers. Once the data is transferred to the device, it can be returned to AWS, where AWS will import the data into Amazon S3. This approach minimizes network bandwidth usage by using physical transfer rather than relying solely on network transfers.

Obviously the solution is B we have to understand the exam is based on real life situations. In that’s e situations everything is not black or white there are nuances. . You are to choose the most effective and balance solution that does not involves extraneous processes. The salient info here is 70 tb , the file is not growing . U don’t want too much band with u don’t want too long time but u don’t need too much speed too. U don’t want to cache the files or work hybrid with it. The docs says. Snowball Edge devices have approximately 39.5 TB or 80 TB of usable space. For example, if you want to move 300 TB of data to AWS over 10 days and you have a transfer speed of 250 MB/s, you need four Snowball Edge devices. So one device can do the 70 tb also the files can be moved in segments smaller files can be batched up and the largest file is in the range that the device can handle.

B. File Gateway shouldnt primarily be used for migration, only extending on-prem capacity. DataSync should be used for Migration. Least possible bandwidth is Snowmobile Edge since it doesn't use network bandwidth.

Answer is C, the Snowball Edge To transport the data, these are sent to the devices through a regional carrier, it does not do so over the internet, in this case the question indicates "Use the least possible bandwidth" the other word The key is "Enterprise uses NFS" which refers to Amazon FSx File Gateway for compatibility.

AWS Snowball Edge is a data migration service that transfers large amounts of data into and out of the cloud quickly, securely, and cost-effectively. Snowball Edge devices are shipped to the customer's on-premises location, where the customer can use the Snowball Edge client to transfer data to the device. Once the data transfer is complete, the customer can return the device to AWS, and AWS will import the data into Amazon S3. This solution will meet the company's requirements of migrating the video files as quickly as possible while using the least possible network bandwidth.

Option D involves setting up an AWS Direct Connect connection between the on-premises network and AWS, deploying an S3 File Gateway on-premises, and transferring the data from the existing NFS file share to the S3 File Gateway. This option would not be the most efficient solution, as it would require transferring the data over the network, which could be slow and may not use the least possible network bandwidth. Overall, Option B is the most efficient solution for transferring large video files to Amazon S3 while using the least possible network bandwidth.

The correct solution that will meet these requirements is Option 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. Option B involves using AWS Snowball Edge, which is a data transfer service that uses secure devices to transfer large amounts of data into and out of AWS. Snowball Edge is particularly well-suited for transferring large amounts of data over long distances, and it can transfer data at much faster speeds than transferring data over the network. To use Snowball Edge, you would first create a Snowball Edge job in the AWS Management Console, and then receive a Snowball Edge device on premises. You would then use the Snowball Edge client to transfer the data from the on-premises NFS file share to the Snowball Edge device. Once the transfer is complete, you would return the device to AWS, and AWS will import the data into Amazon S3.

AWS Snowball Edge Jobs: The transfer of 80 TB or less of your local data copied onto a single device, and then moved into Amazon S3. For import jobs, Snowball devices and jobs have a one-to-one relationship. Each job has exactly one device associated with it. If you need to import more data, you can create new import jobs or clone existing ones. When you return a device of this job type, that data on it is imported into Amazon S3.

This question is just terrible. I think the guys at AWS are talking about Amazon FSx File Gateway. So the reward is "C". Amazon FSx File Gateway optimizes on-premises access to fully managed, highly reliable file shares in Amazon FSx for Windows File Server. Customers with unstructured or file data, whether from SMB-based group shares, or business applications, may require on-premises access to meet low-latency requirements. Amazon FSx File Gateway helps accelerate your file-based storage migration to the cloud to enable faster performance, improved data protection, and reduced cost.

Option C is the first to be ruled out. File gateway (storage gateway) is not a migration tool. It simply bridges data from on-prem and AWS (e.g. S3) with local caching on-prem. They are asking about migrating data... file gateway does not migrate data, it is not a migration solution.

We don't know the available bandwidth, BUT just suppose we can consume exclusively for migration 1Gbps. In this case the migration will take more than 6 days to move the 70TB. A week is also the time used by the snowball devices consuming no bandwidth at all. B - If you choose any other option, you involve +1Gbps bandwidth to be used exclusively for migration, which goes against the LEAST BW requested. For instance, to migrate it in 1 day, you would need 10Gbps.

Even with high-speed internet connections, it can take months to transfer large amounts of data. For example, it can take more than 100 days to transfer 100 TB of data over a dedicated 100-Mbps connection. You can accomplish the same transfer in less than one day, plus shipping time, using two AWS Snowball Edge devices.

Expert Analysis
Why the Answer Is Correct
Option B (AWS Snowball Edge) is the correct answer. Snowball Edge devices provide up to ~80 TB of usable storage per job, making 70 TB a standard use case. The data is copied locally onto the physical device and shipped back to AWS for import into S3 — meaning zero network bandwidth is consumed for the migration itself. The entire process typically completes in 6–9 working days, making it both the fastest and least bandwidth-intensive option. The fact that total storage is 'no longer growing' is a deliberate signal that Snowball Edge's fixed capacity is sufficient and ideal.
Why the Other Options Are Wrong
Option A uses the AWS CLI to upload 70 TB directly to S3 over the internet, consuming the full 70 TB of network bandwidth and taking weeks depending on connection speed — violating both requirements. Option C deploys an S3 File Gateway but transfers data over a public service endpoint, still pushing all 70 TB through the network; it does not reduce bandwidth usage. Option D adds Direct Connect, which typically takes 1–2 months to provision, making it the slowest option despite the dedicated bandwidth; the long provisioning time fails the 'as soon as possible' requirement.
Community Comment Notes
Gatt's analysis is the most thorough, calculating that Snowball Edge transfers 70 TB in under 2 hours locally and completes in 6–9 working days including shipping — far faster than network-based approaches. LuckyAro and th3cookie correctly identify that Direct Connect can take weeks to provision, invalidating option D. PhucVuu's breakdown correctly marks B as the answer because it uses no network bandwidth at all. The dissenting view from Uncolored8034 arguing for C is incorrect: Snowball Edge does not consume network bandwidth — the data is physically shipped, which is precisely why it satisfies the 'least possible network bandwidth' requirement.
Official Reference
Exam Strategy
When a question specifies a large static dataset with 'no longer growing' and demands minimal network bandwidth, immediately look for AWS Snowball Edge as the answer. Also watch for Direct Connect options — the long provisioning lead time (weeks to months) almost always makes DX the wrong choice for 'as soon as possible' migrations.
Frequently Asked Questions
Why doesn't S3 File Gateway count as using the least possible network bandwidth?
S3 File Gateway still transfers all 70 TB of data over the network (internet or Direct Connect) to reach S3. Unlike Snowball Edge, which physically ships data on a device, File Gateway relies entirely on network connectivity.
How long does Direct Connect provisioning take and why does it matter here?
Direct Connect typically takes 4–8 weeks to provision a new physical connection. Since the question requires migrating 'as soon as possible,' the long setup time makes Direct Connect unsuitable compared to Snowball Edge's 6–9 day timeline.
Can Snowball Edge handle files up to 500 GB?
Yes. Snowball Edge devices support large individual files well beyond 500 GB. The device capacity per job is approximately 80 TB, easily accommodating the 70 TB total dataset in this scenario.
