What describes ephemeral storage in the context of AWS EC2?

Permanently stores data
Retains data even after termination
Local storage that is lost upon instance termination
Cloud-based storage

The correct answer is: Local storage that is lost upon instance termination

Ephemeral storage in the context of AWS EC2 is specifically designed to be temporary. It provides fast, temporary storage that is associated with a specific instance. This type of storage is often used for hosting temporary files or data that do not need to persist beyond the life of the instance. When an EC2 instance is launched, it can be configured to use ephemeral storage, which is backed by the physical storage of the underlying hardware. However, this storage is specifically designed to be lost when the instance is terminated or stopped. This characteristic makes it ideal for temporary workloads where data loss is acceptable. In contrast, options that suggest permanence or continuity of data after instance termination do not align with the definition of ephemeral storage. For example, permanent storage types, such as Elastic Block Store (EBS) or S3, offer data retention capabilities despite instance lifecycle changes. Therefore, option C accurately captures the essence of ephemeral storage being temporary and reliant on the instance's lifespan.
