https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/ebs-fast-snapshot-restore.html Amazon EBS fast snapshot restore (FSR) enables you to create a volume from a snapshot that is fully initialized at creation. This eliminates the latency of I/O operations on a block when it is accessed for the first time. Volumes that are created using fast snapshot restore instantly deliver all of their provisioned performance.

Keywords: - Modifications to the cloned data must not affect the production environment. - Minimize the time that is required to clone the production data into the test environment. A: Incorrect - we can do this But it is not minimize the time as requirement. B: Incorrect - This approach use same EBS volumes for produciton and test. If we modify test then it will be affected prodution environment. C: Incorrect - EBS snapshot will create new EBS volumes. It can not restore from existing volumes. D: Correct - Turn on the EBS fast snapshot restore feature on the EBS snapshots -> no latency on first use

Ans D - as per PhucVuu response... what's to debate...

Ye its d cuh

https://docs.aws.amazon.com/ebs/latest/userguide/ebs-restoring-volume.html Its C. reate a new volume from the snapshot. Use the create-volume command. For --snapshot-id, specify the ID of the snapshot to use. For --availability-zone, specify the same Availability Zone as the instance. Configure the remaining parameters as needed.

Answer is D because volumes that are created using fast snapshot restore instantly deliver all of their provisioned performance. Volumes created from normal snapshots will take time to initialize

A: Can work but long cloning time B: Wrong as multi attach will mean changes by test will affect production C: Slow D: Fast restore makes this a quicker option

Answer-D

Amazon EBS fast snapshot restore (FSR) enables you to create a volume from a snapshot that is fully initialized at creation. This eliminates the latency of I/O operations on a block when it is accessed for the first time. Volumes that are created using fast snapshot restore instantly deliver all of their provisioned performance.

why not A? high I/O, no need durability

Needs to minimize the time that is required to clone the production data into the test environment = EBS fast snapshot restore feature

Option C provides an effective solution for cloning large amounts of production data into a test environment with minimized time, high I/O performance, and without affecting the production environment.

The correct answer is D. Here is a step-by-step explanation of how to clone production data into a test environment using EBS snapshots: Take EBS snapshots of the production EBS volumes. Turn on the EBS fast snapshot restore feature on the EBS snapshots. Restore the snapshots into new EBS volumes. Attach the new EBS volumes to EC2 instances in the test environment. The EBS fast snapshot restore feature allows you to restore snapshots more quickly than the default method. This is because the feature uses a process called parallel restore, which allows multiple EBS volumes to be restored at the same time. The EBS fast snapshot restore feature is only available for EBS snapshots that are created in the same AWS Region as the EC2 instances that you are using to restore the snapshots.

For consistently high IO, option A is the solution. Instance store has the highest IO

Option D is the ideal answer.

Take EBS snapshots of the production EBS volumes. Turn on the EBS fast snapshot restore feature on the EBS snapshots. Restore the snapshots into new EBS volumes. Attach the new EBS volumes to EC2 instances in the test environment. Enabling the EBS fast snapshot restore feature allows you to restore EBS snapshots into new EBS volumes almost instantly, without needing to wait for the data to be fully copied from the snapshot. This significantly reduces the time required to clone the production data. By taking EBS snapshots of the production EBS volumes and restoring them into new EBS volumes in the test environment, you can ensure that the cloned data is separate and does not affect the production environment. Attaching the new EBS volumes to the EC2 instances in the test environment allows you to access the cloned data.
