Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 6 discussion

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.

Selected Answer: B
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.

and it says, "The total storage is 70 TB and is no longer growing". Thats why it should be B.

DX Lead times are often longer than I month to establish a new connection.That’s why D is the wrong answer on the other hand.

I will add that the question does not specify if the company already has DA in place or not. If they don't have DA in place, it will take a long time (weeks) for DA connectivity to be setup. Another point for B here, as Snowball is much quicker from this perspective.

It does, because option D says "SET UP a DirectConnect connection", not "use an existing DirectConnect connection".

Selected Answer: B
Keywords: large volume data, least network bandwidth and volume data no longer growing B: use aws snowball edge job is more suitable way to migrate large amount of data with least network bandwidth and very fast. You setup aws snowball edge job physically and copy data to aws snowball edge job and send it to aws and then aws will uploads that for you to s3 bucket C is incorrect since this also offer a high network bandwidth to upload D is incorrect since this require heavy setup, take a week to set up aws direct connect and still network bandwidth A: take a longer to upload this large volume data so this option is incorrect

It is needed to do with urgency, so no more configuration for using internet or expensive connection as direct connect, just transport it with Edge Snowball is the right way.

Selected Answer: B
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.

Selected Answer: B
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.

I choose B The key is: - The total storage is 70 TB and is no longer growing. - Using the least possible network bandwidth. No longer Growing mean 1 time migrate, no need file gw Least Possible Nw Bandwith --> Snowball Edge

Ans B. Agree: Snowball Edge is designed for these types of operations; its more robust and secure because the operation is completed (relatively) quickly. Ans C doesn't really fly.

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".
