Refer to the Exhibit:
An administrator needs to create two virtual machines: VM4 and VM5 that leverage the memory over-commit feature.
Once VM4 is created and running, the administrator notices that it uses only 28GB of RAM.
What will be the maximum RAM that can be allocated to VM5 so that it can be powered on?
Correct Answer: B
Understanding the Exhibit & Memory Allocation
* Thehost has 128GB of physical RAM.
* Thecurrent memory allocationacrossthree VMs (VM1, VM2, VM3) is 128GB, but only92GB is actually utilized.
* This means there is36GB of unutilized memory available for allocation.
Step-by-Step Breakdown
* Existing Memory Usage Before Adding VM4
* Total Physical RAM:128GB
* Used by running VMs (VM1, VM2, VM3):92GB
* Unutilized Memory Available:36GB
* After Creating and Running VM4
* VM4 is allocatedmemory but only utilizes 28GB.
* The table does not show VM4's allocated RAM, but assuming it was given a reasonable allocation, it must have been taken from the36GB unutilized memory pool.
* IfVM4 uses 28GB, theremaining unutilized memory is now (36GB - 28GB) = 8GB.
* Maximum Memory Allocation for VM5
* Sinceonly 8GB remains unutilized, the maximum memory VM5 can be allocated while still allowing it to power on is8GB.
Evaluating the Answer Choices
* (A) 4GB#(Incorrect)
* More memory (8GB) is available, so limiting to 4GB is unnecessary.
* (B) 8GB#(Correct)
* Theremaining unutilized memory after VM4 is 8GB, so VM5 can be allocated up to8GBwhile ensuring it can power on.
* (C) 16GB#(Incorrect)
* Only8GB is left, so 16GB isnot possible.
* (D) 32GB#(Incorrect)
* There isnot enough unutilized memoryto allocate 32GB.
Key Concept: Nutanix Memory Overcommit
* Nutanix AHV supportsmemory overcommit, meaning VMs can be allocated more memory than physically available usingmemory ballooning and swapping.
* However,to power on VM5 without impacting performance, it must fit within the available unutilized memory, which is8GB.
