Correct Answer : Get Lastest Questions and Answer :

Explanation: If the EBS volume stays in the detaching state, the user can force the detachment by clicking Force Detach. Forcing the detachment can lead to either data loss or a corrupted file system. The user should use this option only as a last resort to detach a volume from a failed instance or if he is detaching a volume with the intention of deleting it. The instance does not get an opportunity to flush file system caches or file system metadata. If the user uses this option, he must perform a file system check and repair the procedures.

Correct Answer : Get Lastest Questions and Answer :

Explanation: When a user creates an EBS volume from a snapshot it will have all the contents of the original volume. When the volume is attached but not mounted the user cannot write on that volume. In this case when the user takes a snapshot it will succeed, but will have only the original contents of the volume since the data may not have been modified.
