Nutanix Exam Nutanix NCA-5.15 2 — Questions and Answers
Question 1: Which Nutanix storage optimization feature deduplicates data inline before writing to disk?
- Erasure Coding
- Compression
- Deduplication (Correct answer)
- Tiering
Correct answer: Deduplication
Nutanix deduplication can operate inline, removing redundant data blocks before they are written to the storage layer.
Question 2: What is the minimum number of nodes required to form a Nutanix cluster with data redundancy (RF2)?
- 1
- 2
- 3 (Correct answer)
- 4
Correct answer: 3
RF2 (Replication Factor 2) requires at least 3 nodes so that the cluster can survive a single node failure while maintaining data availability.
Question 3: In Nutanix AHV, what is the role of the Virtual Machine Mobility Infrastructure (ACROPOLIS)?
- Manages storage tiering policies
- Handles VM lifecycle, networking, and storage integration (Correct answer)
- Provides RBAC for Prism
- Configures IPAM for AHV
Correct answer: Handles VM lifecycle, networking, and storage integration
Acropolis is the distributed storage fabric and hypervisor management layer that oversees VM lifecycle, virtual networking, and storage integration on AHV.
Question 4: Which Nutanix feature allows a cluster to automatically relocate data to faster storage tiers when it becomes 'hot'?
- Erasure Coding
- Intelligent Tiering (ILM) (Correct answer)
- Compression
- Deduplication
Correct answer: Intelligent Tiering (ILM)
Intelligent Lifecycle Management (ILM) monitors data access patterns and promotes frequently accessed (hot) data to faster SSD tiers automatically.
Question 5: What does the Nutanix 'Prism Element' interface primarily manage?
- Multiple clusters from a single pane
- A single Nutanix cluster (Correct answer)
- Only AHV virtual machines
- Cloud-connected workloads
Correct answer: A single Nutanix cluster
Prism Element is a per-cluster management interface that provides visibility and control over a single Nutanix cluster.
Question 6: Which protocol does Nutanix Files use to provide NAS file sharing to Windows clients?
- NFS
- iSCSI
- SMB (Correct answer)
- FC
Correct answer: SMB
Nutanix Files uses the SMB (Server Message Block) protocol to deliver file shares to Windows-based clients.
Question 7: What happens to CVM-hosted storage services if the CVM on a node becomes unavailable?
- All cluster storage stops
- The node's VMs stop immediately
- Other CVMs take over storage requests for that node (Correct answer)
- Prism Central manages the storage failover
Correct answer: Other CVMs take over storage requests for that node
Nutanix's distributed architecture allows other CVMs in the cluster to seamlessly serve storage I/O for a node whose CVM has failed.
