When an EC2 EBS-backed (EBS root) instance is stopped, what happens to the data on any ephemeral store
volumes?
A.
Data will be deleted and win no longer be accessible
B.
Data is automatically saved in an EBS volume.
C.
Data is automatically saved as an EBS snapshot
D.
Data is unavailable until the instance is restarted
Correct answer is: A
See: http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/InstanceStorage.html#instance-store-lifetime
However, data in the instance store is lost under the following circumstances:
– The underlying disk drive fails
– The instance stops
– The instance terminates
Thanks,
Frank

The Instance Store and the EBS root are different one. please see refer this link
http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/RootDeviceStorage.html
The right answer is D

Correct answer is A. No data is kept on ephemeral storage after a stop/restart.

This question is confusing/wrong, the EBS backed root volume is not “ephemeral”.
Note: There is no stop action available for instance store backed EC2 instances as it would be the same as terminating the instance as the ephemeral volume would be deleted.
Stop action is only possible for EBS backed root vol.
The correct answer is D

@tom: you can have ephemeral storage attached to an EBS-backed instance: your root volume will be an EBS volume, but additional volumes can then be instance-store (see high storage instance type for example). Correct instance is DEFINITELY A, not D

I agree with Tom – D is correct answer.

Hi! I just took the AWS-SysOps exam few days ago and luckily passed with 90% marks (the passing score is 65% now). I had 55 single choice and multiple choice questions in total, most of them were single answer questions. And, questions on Monitoring and Metrics, Deployment and Provisioning were not easy to answer, other questions on High Availability and Data Management and Analysis were very easy to get the correct answers.
I learned valid AWS-SysOps dumps here — https://drive.google.com/open?id=0B-ob6L_QjGLpUWdPWXRHaERYWlU (recommend you to get the full version 310q AWS-SysOps dumps), all actual AWS-SysOps exam questions were from that 310q AWS-SysOps dumps.
Good Luck, my cool guys!

A.
Data will be deleted and win no longer be accessible
Ephemeral = not persistant. Anything on the root EBS will remain upon reboot.

I guess B.
Follow the question, the volume type which EC2 used is EBS, (not instance store-backed). Hence, data will available after EC2 stop.

The answer is A. It is asking for data on “any ephemeral store volumes” not the data on the EBS root volume. The empermeal store (i.e. instance store) volumes disappear when stopped.

Looks like A because of the aws info listed in the link and below http://docs.aws.amazon.com/AWSEC2/latest/UserGuide/Stop_Start.html
When you stop a running instance, the following happens:
*The instance performs a normal shutdown and stops running; its status changes to stopping and then stopped.
*Any Amazon EBS volumes remain attached to the instance, and their data persists.
*Any data stored in the RAM of the host computer or the instance store volumes of the host computer is gone.

The answer should be A. Ephemeral == Non-persistent.
Whenever we try to stop an Amazon EC2 instance and get the warning message as below.
Warning: Please note that any data on the ephemeral storage of your instance will be lost when it is stopped.

The question have the intention to confuse who is reading. Tell first of the EBS Backed and do the question about ephemeral disk. Correct is A.

When you stop EBS ec2 instance it shows. “Note that when your instances are stopped:
Any data on the ephemeral storage of your instances will be lost”

A- the question is “what happens to the data on any ephemeral store
volumes?” of course that is lost.
In EBS backed what is not lost is “data stored in the attached volumes” – bit that is not the ephemeral store.
