A user has launched an EC2 Windows instance from an instance store backed AMI. The user wants to convert the AMI to an EBS backed AMI. How can the user convert it?
A.
Attach an EBS volume to the instance and unbundle all the AMI bundled data inside the EBS
B.
A Windows based instance store backed AMI cannot be converted to an EBS backed AMI
C.
It is not possible to convert an instance store backed AMI to an EBS backed AMI
D.
Attach an EBS volume and use the copy command to copy all the ephemeral content to the EBS Volume
Suggested Answer:B🗳️
Generally, when a user has launched an EC2 instance from an instance store backed AMI, it can be converted to an EBS backed AMI provided the user has attached the EBS volume to the instance and unbundles the AMI data to it. However, if the instance is a Windows instance, AWS does not allow this. In this case, since the instance is a Windows instance, the user cannot convert it to an EBS backed AMI.
In Amazon EC2, an instance store backed AMI cannot be directly converted to an EBS backed AMI. The root volume of an instance store backed AMI is ephemeral storage that is tightly tied to the physical hardware of the instance and cannot be detached and converted to EBS.
If you want to have an EBS backed AMI, you would need to launch a new instance from the instance store backed AMI, manually create an EBS volume, copy the data from the instance store volume to the EBS volume, and then create a new EBS backed AMI based on that EBS volume.
