✑ Each node is equipped with a single SSD, utilized at 95%
✑ Each node is equipped with three HDDs, utilized at 40%
Why are the guest VMs experiencing high latency?

After using of 75% ssd starts overwhelmed tearing operation, correct is A
Answer is 'B' - if the SSDs are 95% full, they can long take on new writes, therefore writes have to go to HDD, which is much slower.
This exam is obsolete. It is not the NCM-MCI 6.5 break fix exam with 15 questions. It is an outdated exam. I would guess either 5.15 or 6.0, not 6.5.
I think A - which comes first? the Reprovisioning of where the data rests or the because now the Reads are coming from HDD? I think A.
B. On the Nutanix Cluster once a disk (SSD-PCIe, SSD-SATA or DAS-SATA storage tier) reaches 95% full Stargate will not write to that disk https://portal.nutanix.com/page/documents/kbs/details?targetId=kA0600000008hfcCAA D. The question does not indicate the the data is cold, only cold data is read from HDD.
Correct answer is C
Correct
