Ya. S3 based AMI means, Instance Store.

C - https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/terminating-instances.html

C Data is automatically deleted.

Letter C is correct. S3 template storage uses Instance Store, which does not preserve data after the instance is terminated. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/RootDeviceStorage.html

S3 based-AMIs are basically AMIs that are copied to ephemeral disk. Data is lost upon stopping or terminating the instance.

C is the answer S3 backed means that the EC2 is using Instance store and data will not survive the CE2 termination

I agreee the answer is C

Answer is C

Answer C

C. Data is automatically deleted. (Instance Store disk = S3 Based disk)

Answer should be A EBS volumes are saved in S3. S3 being the keyword here. If it asked about your data being on an Instance Store (ephermeral storage), then on termination you would lose the data. When creating an AMI, it is an EBS volume stored in S3. Remember data on Ephermeral storage, will survive a reboot. However, if the instance is stopped,terminated or you lose the underlying physical disk you will lose your data. https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/InstanceStorage.html
