Please ensure you read each step very carefully when carrying out tasks. Remember the devices are real so changes you make may impact another task later.
By not completing one task you may not be able to complete the next as there is a dependency. You should also refer back to your course content to ensure you understand that task that you are carrying out.
If you feel there is an error in the content, please send an email to email@example.com and we will review the issue.
