Topic #: 1
[All AWS Certified Solutions Architect - Professional Questions]

A company's lease of a colocated storage facility will expire in 90 days. The company wants to move to AWS to avoid signing a contract extension. The company's environment consists of 200 virtual machines and a NAS with 40 TB of data. Most of the data is archival, yet instant access is required when data is requested.
Leadership wants to ensure minimal downtime during the migration. Each virtual machine has a number of customized configurations. The company's existing 1
Gbps network connection is mostly idle, especially after business hours.
Which combination of steps should the company take to migrate to AWS while minimizing downtime and operational impact? (Choose two.)

  • A. Use new Amazon EC2 instances and reinstall all application code.
  • B. Use AWS SMS to migrate the virtual machines.
  • C. Use AWS Storage Gateway to migrate the data to cloud-native storage.
  • D. Use AWS Snowball to migrate the data.
  • E. Use AWS SMS to copy the infrequently accessed data from the NAS.

1/8*3600*24=10,800. With 1 Gb netowrk to transfer 40TB data, it takes about 4 days. So snowball is not needed.

"after hours" meaning 16h instead of 24. Which means roughly 6 days for the data transfer to AWS, better than snowball, takes 7 days for data to available on AWS. AC is good.

BC 40TB is easy work for a 1Gbps line so more feasible than snowball

BC with 1Gbps of inactive speed means about 128MBs which will take about 4 days lets say only off hours so it will take about 8 days in total. Better to use Storage File GW no need to order and send a snowball for this

But you need the BW for the SMS migration too, so it takes a lot of time more sharing the same connection for both. Maybe the snowball have more sense in this scenario. BD in my opinion.

C. 1024Mbps is nearly 100MB per second, which will be enough to transfer the 40TB in 90days which data is unchanging(archived). B. SMS is good for mission critical VMs which also guarantees little downtime. A. is wrong, since it will create downtime, . D. Will not be needed. Already explained it can be done online via Storage gateway. E. AWS SMS is for VM, not for data.

BC C is better than D because it's less disruption to the system, which is the question requires.
