Nutanix Certified Professional - Multicloud Infrastructure (NCP-MCI) — Questions and Answers
Question 1: What is the significance of the 'Replication Factor' (RF) setting chosen at cluster creation time?
- It can be changed per VM after deployment without restrictions
- It sets the number of data copies maintained and determines failure tolerance, and changing it requires a full data migration (Correct answer)
- It determines the number of Prism Element instances running in the cluster
- It only affects virtual machine snapshots, not base VM data
Correct answer: It sets the number of data copies maintained and determines failure tolerance, and changing it requires a full data migration
The cluster-level Replication Factor determines how many copies of all data are maintained and directly defines failure tolerance; changing it after deployment requires migrating all existing data.
Question 2: How is a Nutanix cluster IP assigned?
- CVM address
- Node 1 IP
- Gateway IP
- Cluster Virtual IP (VIP) (Correct answer)
Correct answer: Cluster Virtual IP (VIP)
A Nutanix cluster is assigned a Cluster Virtual IP (VIP) that serves as a single, highly available access point for management. This VIP floats between the Controller VMs (CVMs) in the cluster, ensuring that the management interface remains accessible even if an individual CVM fails. It is used for accessing Prism Element and other cluster-wide services.
Question 3: In a Nutanix cluster, what is the purpose of the 'Recycle Bin' for VMs in Prism?

Correct answer: Record objective findings, measurements, and observations factually
Assessment documentation must be objective, factual, and comprehensive.
Question 11: Which Nutanix service is responsible for managing metadata and ensuring data locality on the platform?
- Zookeeper
- Cassandra (Correct answer)
- Acropolis
- Stargate
Correct answer: Cassandra
Cassandra is the distributed metadata store in Nutanix AOS that tracks the location of all data blocks across the cluster, enabling fast lookups and data locality.
Question 12: During a rolling upgrade of AOS, one CVM fails to rejoin the cluster after rebooting. What is the recommended first step?

Question 25: What is the difference between Nutanix Replication Factor 2 (RF2) and RF3?
- RF2 is for SSDs only; RF3 applies to HDD tiers
- RF2 stores 2 copies and tolerates 1 node failure; RF3 stores 3 copies and tolerates 2 simultaneous node failures (Correct answer)
- RF2 requires a dedicated metadata node; RF3 distributes metadata across all nodes
- RF2 uses synchronous replication; RF3 uses asynchronous replication
Correct answer: RF2 stores 2 copies and tolerates 1 node failure; RF3 stores 3 copies and tolerates 2 simultaneous node failures
RF2 maintains 2 data copies providing single-node failure tolerance, while RF3 maintains 3 copies allowing the cluster to survive two simultaneous node failures.
Question 26: After a successful cluster deployment, an administrator finds that CVMs cannot reach external DNS. What is the first configuration element to verify?
- Hypervisor DNS resolver settings
- Prism Element DNS whitelist settings
- CVM firewall rules blocking UDP 53
- CVM network configuration including DNS server IPs and gateway (Correct answer)
Correct answer: CVM network configuration including DNS server IPs and gateway
The CVM network configuration (IP, subnet mask, gateway, and DNS server entries) must be verified first as incorrect settings prevent external name resolution.
Question 27: What is the Nutanix 'Shadow Clone' feature used for?
- Distributing write I/O across multiple nodes simultaneously

Question 44: A Nutanix cluster running RF2 loses two nodes simultaneously. What is the expected impact?
- Storage I/O is suspended until one node recovers
- All VMs are shut down and data becomes inaccessible (Correct answer)
- The cluster enters read-only mode
- The cluster continues operating normally with reduced redundancy
Correct answer: All VMs are shut down and data becomes inaccessible
With RF2, the cluster can tolerate only one node failure; losing two nodes simultaneously results in loss of quorum and data unavailability.
Question 45: Which feature helps clone VMs quickly?
- VM Cloning (Correct answer)

Correct answer: Acropolis Hypervisor
AHV stands for Acropolis Hypervisor, which is Nutanix's native, enterprise-grade hypervisor. It is based on KVM and is deeply integrated with the Nutanix software stack, providing a highly efficient and secure virtualization platform for running virtual machines directly on Nutanix nodes. AHV simplifies the infrastructure by eliminating the need for a separate hypervisor license.
