Guys you need to understand that you don't need to apply magic number when Overcommit ratio is given. the overcommit ratio is the magic number in that case its 8. This means required VM vCPU = 2 * 40 = 80. So cores on host = 80/8 = 10 that means 16 is the closest. I recently passed the Exam and came here to clarify on few question for people also that this is dump is not 100 percent as is in exam but 30-40 % . But If you will understand the concept in these questions you will get through for sure. Like I prepared with Official syllabus understood all the concept. and didi a mock like with this exam and refreshed my concept where I missed the helped in the exam. Many questions looks exact same but the question is changed. So I hope this will help you guys. I will check back this question and the number 1 question in this dump, drop me question in this discussion or question number 1. if anyone need help. Good luck Folks.

Overcommit ratio 8:1: 8 vCPU sharing one core. Nothing more - so no magic number calc. Use 2*40/8=10 => 16 is closest!

Regarding the comments calling for 24 cores: Why would we need MORE cores in the host if we are overcommitting? That doesn't make sense. The point of overcommitting is to get a greater user/desktop density per host. 16 cores gets us there. https://docs.citrix.com/en-us/tech-zone/design/design-decisions/single-server-scalability.html#scalability-factors

2vCpu x 40=80vcpu /5 (magic multipliers) =16 + overcommit. So answer D would be correct.

Too me it is like this: 40Vm's X 2 Cpu's = 80vCPU's per host / 5 (Magic Multiplier for desktops) = 16 ; so answer E is correct.

I think that the correct is E. 2vcpus*40mvs=80vcpus/5(Magic Multipliers)=16 physical cores. https://docs.citrix.com/en-us/tech-zone/design/design-decisions/single-server-scalability.html#the-magic-multipliers

what is the answer if the cpu overcommit is 1.5:1(user group2)
