Exam NCM-MCI topic 1 question 27 discussion

Actual exam question from Nutanix's NCM-MCI

Question #: 27
Topic #: 1

An administrator is monitoring the Nutanix v5.15-based AOS cluster performance logs and notices that a SQL server VM is greatly exceeding its intended maximum IOPS. The administrator has confirmed that a QoS policy was previously created for the group of VMs this server is a member of.
What are two reasons that this VM would exceed its maximum configured IOPS from the QoS Policy? (Choose two.)

A. The VM is missing the required snapshot needed to implement the QoS Policy.
B. The VM was not created as an AFS virtual machine.
C. The SQL Server VM has volume groups attached.
D. It was cloned from another SQL Server VM that was a member of the QoS Policy.

C and D are corrects. If a VM has volume groups attached, then QoS is not applicable and While creating a clone of a VM, any QoS attributes throttle limit set on the original VM might not be applied to the new cloned VM

A. The VM is missing the required snapshot needed to implement the QoS Policy. D. It was cloned from another SQL Server VM that was a member of the QoS Policy. Explanation: The absence of the required snapshot: When a QoS policy is created for a group of VMs, it requires a snapshot to be taken in order to implement the policy. If the VM in question is missing this required snapshot, the QoS policy may not be enforced, allowing the VM to exceed its intended maximum IOPS. Cloning from another VM: If the SQL Server VM was cloned from another SQL Server VM that was already a member of the QoS policy, the new VM may inherit the QoS policy settings, including the maximum configured IOPS. However, if the new VM has different workload characteristics or if the QoS policy was not properly adjusted for the new VM, it may exceed the intended maximum IOPS.
