Nutanix defaults to RF-2 (Replication Factor 2), which keeps two copies of data across different nodes to ensure high availability.
Question 3: What Nutanix feature allows workloads to continue running on a node even when a disk fails, by tolerating the failure without data loss?
- Erasure Coding
- Self-Healing (Correct answer)
- Deduplication
- Compression
Correct answer: Self-Healing
Nutanix's self-healing mechanism automatically reconstructs missing data and redistributes it across healthy nodes after a disk failure.
Question 4: Which Nutanix tool provides command-line access to perform cluster-wide operations such as checking cluster health and managing services?
- nCLI (Correct answer)
- aCLI
- Prism Central CLI
- REST API Explorer

Curator is Nutanix's MapReduce-based cluster management service that handles background tasks like disk balancing, garbage collection, and data consistency checks.
Question 6: Which Nutanix feature enables VMs to be live-migrated away from a node automatically when the node is placed into maintenance mode?
- Acropolis Dynamic Scheduling (Correct answer)
- Host Affinity
- VM-Host Affinity
- vMotion
Correct answer: Acropolis Dynamic Scheduling
Acropolis Dynamic Scheduling (ADS) automatically redistributes VMs across available hosts when a node enters maintenance mode or becomes overloaded.
Question 7: What is the maximum number of nodes that can exist in a single Nutanix cluster running AOS?
- 32 nodes
- 64 nodes
- 128 nodes (Correct answer)
- 256 nodes
Correct answer: 128 nodes
A single Nutanix AOS cluster supports up to 128 nodes, enabling large-scale deployments within a single cluster boundary.
