Nutanix Certified Master – Multicloud Infrastructure (NCM-MCI) — Question 20

An administrator needs to expand a cluster based on AHV and running on Nutanix G5 hardware with a new Nutanix G7 system. The cluster is running AOS 5.10 but the operation fails when expanding the cluster. AOS is running on the new system. There are no issues discovering the node.
Why is the operation failing?

Answer options

• A. AOS version running on G7 is older than the version on the cluster.
• B. Foundation software has not been updated on the cluster.
• C. G7 hardware cannot be added to a G5 cluster.
• D. EVC needs to be configured before cluster expansion

Correct answer: A

Explanation

The operation is failing because the AOS version on the new G7 system is older than the version on the existing cluster, which is AOS 5.10. For cluster expansion to succeed, all nodes must run compatible versions of AOS, making option A the correct answer. The other options are incorrect because they do not relate to the compatibility issue between AOS versions.
