Exam NCP-MCI-6.10 Topic 4 Question 113 Discussion

Explanation:
Understanding the Exhibit & Memory Allocation
The host has 128GB of physical RAM.
The current memory allocation across three VMs (VM1, VM2, VM3) is 128GB, but only 92GB is
actually utilized.
This means there is 36GB 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 allocated memory but only utilizes 28GB.
The table does not show VM4s allocated RAM, but assuming it was given a reasonable allocation, it
must have been taken from the 36GB unutilized memory pool.
If VM4 uses 28GB, the remaining unutilized memory is now (36GB - 28GB) = 8GB.
Maximum Memory Allocation for VM5
Since only 8GB remains unutilized, the maximum memory VM5 can be allocated while still allowing
it to power on is 8GB.
Evaluating the Answer Choices
(A) 4GB â OE (Incorrect)
More memory (8GB) is available, so limiting to 4GB is unnecessary.
(B) 8GB âoe… (Correct)
The remaining unutilized memory after VM4 is 8GB, so VM5 can be allocated up to 8GB while
ensuring it can power on.
(C) 16GB â OE (Incorrect)
Only 8GB is left, so 16GB is not possible.
(D) 32GB â OE (Incorrect)
There is not enough unutilized memory to allocate 32GB.
Key Concept: Nutanix Memory Overcommit
Nutanix AHV supports memory overcommit, meaning VMs can be allocated more memory than
physically available using memory ballooning and swapping.
However, to power on VM5 without impacting performance, it must fit within the available
unutilized memory, which is 8GB.
