SolarWinds SCP exam


I am already trying to book for SCP-500 exam but I am a little bit confused, as I saw when I want to book I should choose between NPM,NCM,NTA,ARM...etc, but I thought that the exam contain all these topics when I prepared to it , so kindly  anyone can help me and explain to me that I should take all these exams to take the certificate or there is another way to book for SCP exam.

thank you
