Nutanix Exam Nutanix NCP 4 — Questions and Answers
Question 1: Which Nutanix AOS feature reduces storage consumption by identifying and eliminating redundant data blocks across VMs in a storage container?
- Compression
- Deduplication (Correct answer)
- Erasure Coding
- Thin Provisioning
Correct answer: Deduplication
Deduplication eliminates duplicate data blocks within a container, significantly reducing storage footprint especially in VDI environments with many similar VMs.
Question 2: In Nutanix, what does 'Erasure Coding' (EC-X) provide compared to standard replication?
- Faster write performance with no overhead
- Equivalent data protection with lower storage overhead (Correct answer)
- Higher replication factor for critical VMs
- Synchronous replication to a remote site
Correct answer: Equivalent data protection with lower storage overhead
Erasure Coding provides the same data protection as RF-2 or RF-3 while using significantly less storage capacity by storing parity data instead of full replicas.
Question 3: Which Nutanix product provides a Kubernetes service for deploying and managing containerized applications on Nutanix infrastructure?
- Nutanix Era
- Nutanix Karbon (Correct answer)
- Nutanix Calm
- Nutanix Objects
Correct answer: Nutanix Karbon
Nutanix Karbon (now NKE - Nutanix Kubernetes Engine) is a managed Kubernetes service that simplifies deploying, managing, and scaling Kubernetes clusters on Nutanix.
Question 4: What is the function of the Nutanix 'Stargate' service running on each CVM?
- Manages cluster metadata distribution
- Handles all VM I/O requests and data path operations (Correct answer)
- Provides REST API access to cluster resources
- Manages VM lifecycle and scheduling
Correct answer: Handles all VM I/O requests and data path operations
Stargate is the data I/O gateway on each CVM that handles all read and write operations between the hypervisor and the distributed storage fabric.
Question 5: In Nutanix Calm, which entity represents a deployable unit consisting of multiple services, configurations, and actions for an application?
- Profile
- Blueprint (Correct answer)
- Runbook
- Project
Correct answer: Blueprint
A Blueprint in Nutanix Calm defines the complete application topology, including services, dependencies, credentials, and lifecycle actions for automated provisioning.
Question 6: Which Nutanix feature allows administrators to specify that certain VMs should always run on specific hosts or be kept away from specific hosts?
- Acropolis Dynamic Scheduling
- VM-Host Affinity Policies (Correct answer)
- Protection Domains
- Placement Groups
Correct answer: VM-Host Affinity Policies
VM-Host Affinity Policies in AHV allow administrators to define rules that pin VMs to specific hosts or ensure VMs are spread across different hosts for HA.
Question 7: What is a Nutanix 'Consistency Group' used for within a Protection Domain?
- Ensuring VMs are always co-located on the same node
- Grouping VMs so their snapshots are taken simultaneously for crash consistency (Correct answer)
- Defining network segmentation rules between VM groups
- Configuring shared storage volumes for clustered applications
Correct answer: Grouping VMs so their snapshots are taken simultaneously for crash consistency
A Consistency Group within a Protection Domain ensures that all included VMs are snapshotted at the exact same point in time, maintaining write-order consistency for multi-VM applications.
