Which of the below mentioned activities is the user performing with the command given above?
Creating a file system on the EBS volume
Mounting the device to the instance
Pre warming the EBS volume
Formatting the EBS volume
Explanations:
The command does not create a file system; it writes zeroed data to the volume. Creating a file system involves using commands likemkfsormkfs.ext4.
The command does not mount the device. Mounting would involve commands likemountto attach the device to the directory structure.
The command is writing zeroes to the volume, which is commonly used for pre-warming (ensuring blocks are allocated and ready for use), optimizing the EBS volume for performance.
The command does not format the volume. Formatting involves creating a file system, which isn’t happening here; it’s just writing zeros to the disk.
If I’m correct, the answer is:
Pre warming the EBS volume
