I hope all is well. Glad that you are going through the course and enjoying it.
I am not sure when the practice questions may be updated, as they are from 3rd party vendors, and they update and release content according to their own schedule, which may not always match ours in terms of how quickly we bring updates out.
Once there are any updates from any of our partners, we do integrate them into the course as soon as they are ready to be used.
In terms of Practice Labs, there are none for this course currently. You do see me in the course using a live Azure tenant, and doing all of the demonstrations in that tenant live, n real time during the episode. I would suggest that you consider getting a demo tenant of your own set up if you are able to, and use that to practice.
You can access and set up a tenant from Microsoft here:
If you have any other question as you move through the course, please be in touch as needed. My direct e-mail is: email@example.com
Good Luck !!!
