Issues with practice exam D-PDC-DY-23 - Dell PowerSwitch Data Center Deploy

Hi All,

I have read about some issues with those practice exams, I failed it with 50% ( wondering why so many people have exactly 50% ) I have answered 5 of 6 questions 

1st 95% sure correct

2nd 95% sure correct

3rd 80% sure correct

4th missed only one small bit 

5th again 95% sure correct

6th missed most due to time ran out

With the above in place I am sure this should be an easy pass, is it possible to raise it with Dell to review my answers?

At least one bit was not clear when on questions they provided different "number" than on the diagram, I have configured it based on the Question but the diagram would make more sense
