MS 700 Lab Environment

Hi all

I'm in the process of working towards the MS-700 exam, I've already done the MS-900 & AZ-900 to get the hang of Microsoft exams a little more, even though I've worked in IT for more years than I care to remember.

However, can someone help me out with a couple of questions

 - MS-700 exam lab, I'm looking for somewhere that I can look over the Teams admin center to get hands on experience with the environment, what is the best means of getting this setup without having to purchase an environment through Microsoft, as it's going to be purely for getting my head in the right place ahead of the exam.

 - Can someone also confirm if the MS-700 is open book exam following the Microsoft exam changes ?

Thanks in advance

James
