Common Mistakes

💡 Hint

Common Mistakes

Using 'install' tries to add a patch instead of undoing it.

Using 'status' only shows patch info, does not rollback.

The rollback option is used to undo the last applied patch.

4fill in blank

Fill both blanks to create a command that lists all available patches and filters for critical ones.

💡 Hint

Common Mistakes

Using 'install' instead of 'list' shows patch installation, not listing.

Using 'rollback' is for undoing patches, not listing.

The list option shows all patches, and grep critical filters to show only critical patches.

5fill in blank

hard

Fill all three blanks to write a command that verifies a patch file, installs it if valid, and then checks the patch status.

SCADA systems

scada-patch-manager --[1] patch123.scd && scada-patch-manager --[2] patch123.scd && scada-patch-manager --[3]

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

💡 Hint

Common Mistakes

Skipping verification can cause errors if the patch is corrupted.

Checking status before installation does not confirm the new patch.

First, verify checks the patch file integrity. Then install applies it. Finally, status confirms the patch is installed.
