Hi Allaudeen,
There was a bug in the Configure virtual machine availability module that has been corrected. This bug prevented the module from showing as Completed.
Please navigate to the start of the module and quickly go through all 12 units. It should only take few minutes to scroll and click through all of them. After you have gone through it the module should actually register as complete this time, with all green checks, etc.
Please click Accept Answer and upvote if the above was helpful.
Thanks.
