Question: 1 / 400

Which statement is true regarding EBS storage and instance store in EC2?

EBS is ephemeral, and data is lost when the instance stops

Instance store is persistent, and data remains after stopping

EBS is persistent, and data remains when an instance stops

EBS (Elastic Block Store) volumes are designed to provide durable, persistent storage for Amazon EC2 instances. When an EC2 instance that uses EBS storage is stopped, the data stored on EBS persists, allowing you to retain your data even when the instance is not running. This is particularly useful for applications that require reliable storage, as you can stop and start instances without losing your data.

In contrast, instance store volumes are ephemeral, meaning that any data stored on them is lost if the instance is stopped or terminated. This characteristic makes instance store suitable for temporary storage needs, but it is not reliable for data that needs to persist beyond the life of the instance.

Thus, the statement that EBS is persistent and retains its data when an instance stops accurately reflects the nature of EBS in the context of EC2 storage.
