#12

Kicky:
@Basavraj Nilkanthe,the question says to request for “0.2” cpu. Not 2 cpu

#13

Rajesh Sinha:
As per question, you can use 200m i.e .2 not 2 core

#14

Mohamed Ayman:
Yes, you requested 2000m but you need to request 200m.

#15

Basavraj Nilkanthe:
thats great finding, thank you guys

#16

Basavraj Nilkanthe:
i will test it again

#17

Basavraj Nilkanthe:
Thanks Guys, It is working as expected after putting --requests=cpu=.2 and really it was consuming my more time while finishing lighting lab and I was manage to finish first four questions in 35 min and because of this issue, it took this time… So it is important to read questions carefully before taking exam …
