Nutanix Exam Nutanix NCA-5.15 3 — Questions and Answers
Question 1: Which Nutanix component is responsible for running the hypervisor and hosting user VMs on each node?
- Controller VM (CVM)
- Prism Central
- AOS
- Host (AHV or ESXi) (Correct answer)
Correct answer: Host (AHV or ESXi)
The host layer (running AHV, ESXi, or Hyper-V) is responsible for running the hypervisor and hosting user virtual machines on each Nutanix node.
Question 2: In a Nutanix environment using Erasure Coding (EC-X), what is the primary benefit over standard replication?
- Faster read performance
- Reduced storage capacity overhead (Correct answer)
- Simplified VM migration
- Lower CPU utilization
Correct answer: Reduced storage capacity overhead
Erasure Coding reduces the storage overhead needed for data protection compared to full replication, allowing more usable capacity from the same raw storage.
Question 3: Which Nutanix tool provides a guided check of cluster health, covering hardware, software, and configuration best practices?
- Prism Pro
- Nutanix Pulse
- NCC (Nutanix Cluster Check) (Correct answer)
- LCM (Life Cycle Manager)
Correct answer: NCC (Nutanix Cluster Check)
NCC (Nutanix Cluster Check) is the diagnostic framework that runs hundreds of health checks across hardware, software, and configuration on a Nutanix cluster.
Question 4: What is the function of the Nutanix Distributed Storage Fabric (DSF)?
- Manages inter-cluster WAN connectivity
- Pools local storage across all nodes into a shared logical datastore (Correct answer)
- Provides network virtualization for AHV
- Replicates data to public cloud
Correct answer: Pools local storage across all nodes into a shared logical datastore
The Distributed Storage Fabric pools the local storage resources of all nodes in a cluster into a single, shared, logical datastore accessible by all VMs.
Question 5: When configuring a VM in Nutanix AHV using Prism, which virtual NIC type is recommended for best performance?
- E1000
- VMXNET2
- Virtio (Correct answer)
- RTL8139
Correct answer: Virtio
The Virtio (paravirtualized) NIC driver offers the best network performance for VMs running on AHV due to reduced overhead compared to emulated adapters.
Question 6: Which Nutanix feature enables automated software and firmware updates for cluster components?
- NCC
- Prism Central
- LCM (Life Cycle Manager) (Correct answer)
- Nutanix Calm
Correct answer: LCM (Life Cycle Manager)
Life Cycle Manager (LCM) automates the discovery and application of software and firmware updates for Nutanix cluster components.
Question 7: Which Nutanix storage container setting enables inline data reduction without requiring additional hardware?
- vDisk encryption
- Compression and deduplication settings on the container (Correct answer)
- iSCSI multipathing
- Replication Factor 3
Correct answer: Compression and deduplication settings on the container
Compression and deduplication are container-level settings in Nutanix that perform data reduction inline or post-process without requiring additional hardware.
