💡 Hint

Common Mistakes

Using +write grants write permissions, not read-only.

Using +allcommands grants all permissions, not read-only.

The +@read command allows read-only access to all keys.

Confusing the password with the permission name.

The password is set with >secret. The permission to set keys is +set.

💡 Hint

Common Mistakes

Using off disables the user but does not reset permissions.

Using delete or remove are invalid commands.

The reset keyword removes all permissions and disables the user.

4fill in blank

hard

Fill both blanks to allow user 'dave' to only read keys starting with 'app:' and execute the 'get' command.

Redis

ACL SETUSER dave on >pass123 ~[1] +[2]

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

Aapp:*

Bapp:

Cget

Dset

Attempts:

3 left

💡 Hint

Common Mistakes

Using 'app:' without wildcard does not match keys properly.

Using +set instead of +get grants write permission.

The key pattern app:* restricts access to keys starting with 'app:'. The +get command allows reading keys.

5fill in blank

hard

Fill all three blanks to create a user 'eve' with password '1234', access only to keys starting with 'user:', and permission to execute 'set' command.

Redis

ACL SETUSER eve on >[1] ~[2] +[3]

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

A1234

Buser:*

Cget

Dset

Attempts:

💡 Hint

Common Mistakes

Forgetting the wildcard * in the key pattern.

Confusing the commands and permissions.

The password is 1234. The key pattern user:* restricts keys. The +set command allows setting keys.
