A resource pool in a cloud tenant has 90 GB of memory and 120 cores. The cloud administrator needs to maintain a 30% buffer for resources for optimal performance of the hypervisor. Which of the following would allow for the maximum number of two-core machines with equal memory?
A. 30 VMs, 3GB of memory
B. 40 VMs, 1,5GB of memory
C. 45 VMs, 2 GB of memory
D. 60 VMs, 1 GB of memory
A. would leave no buffer for memory (30 VM’s x 3GB of Ram = 90)
C. would leave no buffer for memory (45 VM’s x 2GB of Ram = 90)
D. would leave no buffer for CPU cores ( 60*2 cores = 120).
B. is the only one that gives a resource buffer on both cores and memory
