  1. crumple says:

    Answer is A.
    When you create your EC2 instance and assign storage, the ROOT volume is set to be deleted on termination by default. Any additional volumes are set to remain as a default setting, but you can change either one of these if desired.

    Answer is B , EBS is a separate service.

    You are setting a flag “deleted on termination of the instance” of root EBS volume , which doesn’t mean than EBS volume lifetime is decided with EC2 instance , by enabling the flag deleted on termination of the instance” to a root EBS volume there will be a separate backend process created and which deletes the root EBS volume when event triggered by EC2 termination.Also this particular mapping only available for root EBS volume.

    B.

    The answer should be (A) if the question has the word “Root”.
    And by default EBS volumes created, none root, don’t get deleted. They only get deleted if you check the box under “Delete on Termination”.

    answer is B

    Q: What happens to my data when a system terminates?

    The data stored on a local instance store will persist only as long as that instance is alive. However, data that is stored on an Amazon EBS volume will persist independently of the life of the instance. Therefore, we recommend that you use the local instance store for temporary data and, for data requiring a higher level of durability, we recommend using Amazon EBS volumes or backing up the data to Amazon S3. If you are using an Amazon EBS volume as a root partition, you will need to set the Delete On Terminate flag to “N” if you want your Amazon EBS volume to persist outside the life of the instance.
