Typing the wrong file system type after mkfs.

The correct command uses mkfs.ext4 to create an ext4 file system.

4fill in blank

hard

Fill both blanks to create a dictionary comprehension that maps device names to their file system types if the type is ext4.

Linux CLI

fs_map = {dev: fs for dev, fs in devices.items() if fs [1] [2]

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using '!=' instead of '==' in the condition.

Checking for 'xfs' instead of 'ext4'.

The dictionary comprehension filters devices where the file system type equals 'ext4'.

5fill in blank

hard

Fill all three blanks to create a dictionary comprehension that maps uppercase device names to their file system types only if the type is xfs.

Linux CLI

fs_map = {{ [1]: [2] for [3], fs in devices.items() if fs == 'xfs' }}

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using fs.upper() as key instead of dev.upper().

Using dev instead of dev.upper() for keys.

Filtering for 'ext4' instead of 'xfs'.

The comprehension maps uppercase device names (dev.upper()) to their file system types (fs) for devices where fs is 'xfs'.
