CE question

in Security+
Quick question here on the CE program if I get my security + than that automatically renews my network + and a+. Obviously if you continue to take the Security + every 3 years before expiration than you wouldnt have an issue keeping all 3 active. The question is if you let them expire wold you than have to take all 3 exams to get recertified or would you only have to take the Security + to renew all 3?
