Cluster Deployment and Configuration Flashcards

Which Nutanix configuration allows administrators to define the maximum storage capacity a single VM can consume from a container?

Answer: vDisk size limit

vDisk size limits can be set at the container level to restrict how much storage any individual virtual disk within that container can consume.

After a successful cluster deployment, an administrator finds that CVMs cannot reach external DNS. What is the first configuration element to verify?

Answer: CVM network configuration including DNS server IPs and gateway

The CVM network configuration (IP, subnet mask, gateway, and DNS server entries) must be verified first as incorrect settings prevent external name resolution.

What happens to running VMs when a CVM on the same node goes down in an AHV-based Nutanix cluster?

Answer: VMs continue running but I/O is served by CVMs on other nodes transparently

When a CVM fails, running VMs on the same node transparently redirect their I/O to CVMs on other nodes, maintaining availability without interrupting VM operation.

Which Foundation deployment mode allows imaging multiple clusters across different physical sites from a single Foundation instance?

Answer: Foundation Central

Foundation Central is a scalable deployment tool that enables imaging and creating multiple clusters across different locations from a centralized management point.

An administrator wants to ensure that specific VMs always run on nodes within a particular subset of cluster nodes. Which Nutanix feature enables this?

Answer: VM-Host Affinity Policy

VM-Host Affinity Policies in AHV allow administrators to define rules that pin or prefer specific VMs to run on designated hosts within the cluster.

When using Prism Central to manage multiple Nutanix clusters, what type of authentication can be configured to provide single sign-on across all managed clusters?

Answer: SAML 2.0 or LDAP/Active Directory integration

Prism Central supports SAML 2.0 identity providers and LDAP/Active Directory integration to provide centralized authentication and SSO across all managed clusters.

What is the significance of the 'Replication Factor' (RF) setting chosen at cluster creation time?

Answer: It sets the number of data copies maintained and determines failure tolerance, and changing it requires a full data migration

The cluster-level Replication Factor determines how many copies of all data are maintained and directly defines failure tolerance; changing it after deployment requires migrating all existing data.
