Nutanix NCA study guide
Nutanix NCA · Work through your exam, one topic at a time.
The Nutanix Certified Associate (NCA) is an entry-level credential for IT professionals who work with or alongside Nutanix enterprise cloud infrastructure. It is aimed at administrators, support engineers, and presales or operations staff who need a working vocabulary for the platform rather than deep implementation expertise. The Nutanix NCA study guide has 9 sections and about 2,829 words.
01Nutanix Enterprise Cloud Fundamentals
Nutanix is a hyperconverged platform: AOS (the distributed cluster software) runs on every node alongside a standard hypervisor - AHV , ESXi, or Hyper-V - with one Controller VM (CVM) per node owning that node's local disks. Everything else (Prism, Flow, Files, Objects, Volumes, Calm, Leap, Era, Move, Karbon) is a service layered on that foundation.
326 words, about 2 min02Cluster Architecture and Components
A Nutanix node is hardware + hypervisor + CVM . The CVMs across nodes form a distributed system, and each service has a specific job: Genesis - bootstrap and cluster-formation service; it starts CVMs and coordinates cluster services.
335 words, about 2 min03Virtual Machine Management with AHV and Prism
AHV is Nutanix's native, KVM-based hypervisor. It is included with AOS - no separate hypervisor licence - and is managed entirely from Prism Element (single cluster) or Prism Central (multi-cluster).
309 words, about 2 min04Storage and Data Services
AOS presents a Distributed Storage Fabric (DSF) across all nodes. Physical disks are pooled; on top of that you create storage containers - logical constructs that carry policy: replication factor, compression, deduplication, erasure coding.
329 words, about 2 min05Networking
Each AHV host runs Open vSwitch (OVS) . The default topology is a bridge ( br0 ), a bond ( bond0 ) aggregating the physical uplinks, and per-VLAN virtual networks that VMs attach to.
315 words, about 2 min06Data Protection and Disaster Recovery
A Protection Domain (PD) groups VMs so they are snapshotted consistently together; schedule local snapshots and optionally replicate them to a remote cluster. In Prism Central, the equivalent higher-level construct is a protection policy applied through categories.
295 words, about 1 min07Monitoring, Alerting, and Cluster Health
Prism Element and Prism Central expose the same core surfaces: Health (cluster-wide status), Alerts (conditions needing attention), Events (informational/past activity), Tasks (in-flight operations), and per-entity performance charts in Analysis . Operational tooling to know: NCC (Nutanix Cluster Check) - the health-check framework.
316 words, about 2 min08Security and Access Control
Authentication proves identity: local Prism users, or directory integration with Active Directory/LDAP . Authorisation decides what that identity can do: RBAC roles plus scope.
304 words, about 2 min09Lifecycle and Upgrade Management
LCM (Lifecycle Manager) is the upgrade engine inside Prism. Its workflow is: run inventory (LCM discovers current software and firmware versions), review available updates and compatibility, then apply.
