S1 — Recognize Nutanix Solutions and Tools 21 cards
1.1
Which hypervisors can NCI run on?
AHV (included) and VMware ESXi. Check the Supported Hypervisors page for your AOS release.
1.1
What runs on every Nutanix node to serve storage?
The Controller VM (CVM). It owns the node's disks and runs Stargate, Cassandra, Curator, Zookeeper and Prism.
1.1
Which CVM service handles data I/O?
Stargate.
1.1
Which CVM service stores cluster metadata?
Cassandra.
1.1
Which IP can you use to reach Prism Element directly?
The IP of any CVM in the cluster (or the cluster virtual IP).
1.1
What is the Distributed Storage Fabric?
AOS's scale-out storage layer. It pools every node's local disks into shared storage.
1.1
What happens when Stargate/Cassandra keep failing on one node?
The cluster redirects that node's I/O path to another CVM (autopathing). The VMs keep running.
1.1
Minimum nodes for RF3 / FT2?
5 nodes.
1.2
Which Nutanix service gives S3-compatible object storage at petabyte scale?
Objects.
1.2
Which Nutanix service gives SMB/NFS file shares?
Files.
1.2
Which Nutanix storage service best fits a Microsoft SQL/Windows failover cluster needing shared disks?
Volumes (iSCSI block storage).

Through which address do external clients reach Volumes storage?
The Data Services IP.
1.2
Where do you see the cluster runway?
On the Prism Central main dashboard (NCM Intelligent Operations).

Database lifecycle: provisioning, cloning, patching, and point-in-time recovery (time machine).

Name three things NGT enables.
Application-consistent (VSS) snapshots, Self-Service Restore, and VM mobility drivers / guest customization.

Foundation vs Foundation Central?
Foundation images nodes and creates a cluster. Foundation Central does it remotely and at scale (zero-touch).
1.3
What does a two-node ROBO cluster need to stay available through a node failure?
A Witness VM at a third site.
1.3
What is X-Ray?
A benchmarking and test-scenario tool for proofs of concept.

What is Nutanix Collector?
A tool that gathers configuration and utilisation data from an existing environment for sizing.
