Topic #: 1
[All AWS Certified Solutions Architect - Associate SAA-C03 Questions]

A company is storing 700 terabytes of data on a large network-attached storage (NAS) system in its corporate data center. The company has a hybrid environment with a 10 Gbps AWS Direct Connect connection.

After an audit from a regulator, the company has 90 days to move the data to the cloud. The company needs to move the data efficiently and without disruption. The company still needs to be able to access and update the data during the transfer window.

Which solution will meet these requirements?

  • A. Create an AWS DataSync agent in the corporate data center. Create a data transfer task Start the transfer to an Amazon S3 bucket.
  • B. Back up the data to AWS Snowball Edge Storage Optimized devices. Ship the devices to an AWS data center. Mount a target Amazon S3 bucket on the on-premises file system.
  • C. Use rsync to copy the data directly from local storage to a designated Amazon S3 bucket over the Direct Connect connection.
  • D. Back up the data on tapes. Ship the tapes to an AWS data center. Mount a target Amazon S3 bucket on the on-premises file system.

For those who wonders why not B. Snowball Edge Storage Optimized device for data transfer is up to 100TB https://docs.aws.amazon.com/snowball/latest/developer-guide/device-differences.html

The question explicitly mentioned "devices", also Snowball Edge Storage Optimized is 80TB HDD. So it is possible, but the answer is A because we can transfer with DataSync in 6.5 days.

10GBs * 24*60*60 =864,000 GB estimate around 864 TB a day, 2 days will transfer all data. But for snowball at least 4 days for delivery to the data center.

This account is wrong but I get your point. It is wrong cause 10Gb/s is not the same as 10GB/s (Gigabits vs Gigabytes). However, the correct count is 864Tb/8 = 108TB per day. In one week you should've transferred all the data.

folks, you had to consider the typical TCP overheads for such over-the-wire data transfers.... it could be as high as 70% of the total available bandwidth due to a wide variety of factors

That's right, 1 GB = 8 Gb. Essentially we have a speed of 1.25GB/s.

700TB with a Bandwidth of 10Gbps takes approximately 7 days, 3 Hours, 2 Minutes, 7 Seconds As per the below link>> https://expedient.com/knowledgebase/tools-and-calculators/file-transfer-time-calculator/ So Option A is Correct & using AWS Datasync facilitates further access to data still present in the OnPrem to access and S3 provides with unlimited data storage capacity

A- Porque La compañía todavía necesita poder acceder y actualizar los datos durante la ventana de transferencia B-Aunque esta podria ser una opcion porque dice de enviar los dispositivosal al centro de datos que serian mas o menos entre 9 y 10 dispositivos ya que el almacenamiento de storage optimized es de 80 TB el problema esta en que con Snowball Edge Storage Optimized no se puede acceder y actuializar a los datos durante la transferencia

From Google Translate: A- Because The company still needs to be able to access and update the data during the transfer window B-Although this could be an option because it says that sending the devices to the data center would be more or less between 9 and 10 devices since the storage optimized storage is 80 TB, the problem is that with Snowball Edge Storage Optimized it does not Data can be accessed and updated during transfer

(B) is incorrect bc although Mountpoint for S3 is possible for on-premises NAS, this is not as efficient as AWS DataSync. Data updates made during the transfer window would have to be resolved later.

I will put simple calculation for oyu guys to just store in your head to quickly answer: for 10GBPS its 1.25GBPS becasue its bits to bytes. for one minute its 75GBPS for one hour its 4500 GBPS for one day its 10.8 TB so you can calculate easily if you just store these numbers in your head. lets say if question is 1GBPS DirectConnect that meand everything above should be divide by 8. cool

Critical requirement: "The company needs to move the data efficiently and without disruption." B: Causes disruption C: I don't think that is possible without a gateway kind of thing D: Tape backups? " Mount a target Amazon S3 bucket on the on-premises file system"? This requires some gateway which is not mentioned A is the answer as DataSync allows transfer without disruption and with 10Gbps, it can be done in 90 days.
