Selected Answer: C

It's no longer call "Defined Duration". Now we would use "Persistent Request" not "one-time" request. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/spot-requests.html Request type: The Spot Instance request type that you choose determines what happens if your Spot Instance is interrupted. One-time: Amazon EC2 places a one-time request for your Spot Instance. If your Spot Instance is interrupted, the request is not resubmitted. Persistent request: Amazon EC2 places a persistent request for your Spot Instance. If your Spot Instance is interrupted, the request is resubmitted to replenish the interrupted Spot Instance.

Update July 2021 – Spot Instances with a defined duration (also known as Spot blocks) are no longer available to new customers as of July 1, 2021. For customers that have previously used the feature, we will continue to support Spot Instances with a defined duration until December 31, 2022. If your workload is interruption tolerant, we recommend that you use Spot Instances without setting a defined duration. If your workload is not interruption tolerant we recommend that you use On-Demand instances for the required duration of your workload.
