pg32 “Overhead Memory on Virtual Machines”
table 3-2
Note that more vCPUs = more memory overhead
But really VMware…you just give me diarrhea of the brain w/ questions like these.
ROFL, I agree about the diarrhea. Who on Earth would want to reduce memory overhead by reducing the performance of their VMs ???????????????????????????????????????????????????????????
Cool… 20 of 19 questions are like these…
A & D.
Overhead memory includes space reserved for the virtual machine frame buffer and various virtualization data structures, such as shadow page tables.
Overhead memory depends on the number of virtual CPUs and the configured memory for the guest operating system.
the questions asked in exams are to familiarize with the technology and not mainly focused on realistic scenario..
