A vSphere HA cluster with four hosts has admission control configured to tolerate one host failure.
Which statement is true if a fifth host is added?
A.
CPU and Memory capacity will be set to 50%.
B.
CPU and Memory capacity will be set to 30%.
C.
CPU and Memory capacity will be set to 25%.
D.
CPU and Memory capacity will be set to 20%.
D is correct, as there has to be a reservation of 100% / 5 Hosts to compensate one host failure. Thats exactly 20%.
4 Hosts had the reservation of 25%, to compensate a single host failure.
