The question is " what happens to the data on any ephemeral store volumes"? The first part of the sentence about EBS-backed doesn't matter. Ephemeral store refers to the storage on the instance which is deleted. Answer is A.
Correct Answer: A
This one was tricky. The instance has a root EBS volume (Persistent), but the question is asking about what happens to any Instance-store volumes (Ephemeral) attached to it.
If it's ephemeral, data is deleted and will be no longer accessible.
A -
Ephemeral storage is the volatile temporary storage attached to your instances which is only present during the running lifetime of the instance. In the case that the instance is stopped or terminated or underlying hardware faces an issue, any data stored on ephemeral storage would be lost. This storage is part of the disk attached to the instance. It turns out to be a fast performing storage solution, but a non-persistent one, when compared to EBS backup volumes.
A.
The data in an instance store persists only during the lifetime of its associated instance. If an instance reboots (intentionally or unintentionally), data in the instance store persists. However, data in the instance store is lost under any of the following circumstances:
The underlying disk drive fails
The instance stops
The instance hibernates
The instance terminates
shouldnt it be D, since instance is stopped and not terminated, instance backed store only loses data when terminated, you can restart the instance and data will still be there. if you terminate data is lost
Answer is A - They mention ephemeral storage which is also known as "instance storage".
All data is lost when the instance is terminated since it's instance storage.
Ans should be B becoz , The question is wrong.
It should be either Instance Store-backed Instances or EBS-backed Instances. The question says EBS Backed, but ans shows Instance store related.
