Nutanix Certified Master – Multicloud Infrastructure (NCM-MCI) — Question 5

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.)

Answer options

• 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.

Correct answer: C, D

Explanation

Option C is correct because if the SQL Server VM has volume groups attached, it can lead to increased IOPS beyond the defined QoS limits. Option D is also correct since cloning a VM from another that is part of the QoS Policy can result in the new VM inheriting the performance characteristics of the original, thereby exceeding the IOPS cap. Options A and B are incorrect as they do not directly affect the ability to exceed the QoS limits.
