NCP Cluster Deployment and Configuration 5 — Questions and Answers
Question 1: Which Nutanix configuration allows administrators to define the maximum storage capacity a single VM can consume from a container?
- QoS throttling policy
- Storage container whitelist
- vDisk size limit (Correct answer)
- Container advertised capacity
Correct 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.
Question 2: After a successful cluster deployment, an administrator finds that CVMs cannot reach external DNS. What is the first configuration element to verify?
- CVM firewall rules blocking UDP 53
- CVM network configuration including DNS server IPs and gateway (Correct answer)
- Prism Element DNS whitelist settings
- Hypervisor DNS resolver settings
Correct 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.
Question 3: What happens to running VMs when a CVM on the same node goes down in an AHV-based Nutanix cluster?
- VMs are immediately live-migrated to other nodes
- VMs continue running but I/O is served by CVMs on other nodes transparently (Correct answer)
- VMs pause until the local CVM recovers
- VMs are automatically restarted on other nodes by HA
Correct 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.
Question 4: Which Foundation deployment mode allows imaging multiple clusters across different physical sites from a single Foundation instance?
- Standalone Foundation Mode
- Foundation Central (Correct answer)
- Prism Central Deployment
- Remote Foundation Agent
Correct 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.
Question 5: An administrator wants to ensure that specific VMs always run on nodes within a particular subset of cluster nodes. Which Nutanix feature enables this?
- VM-Host Affinity Policy (Correct answer)
- Fault Domain Configuration
- Storage Container Mapping
- Network Segmentation Policy
Correct 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.
Question 6: 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?
- RADIUS authentication only
- Local user replication
- SAML 2.0 or LDAP/Active Directory integration (Correct answer)
- SSH key-based authentication
Correct 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.
Question 7: What is the significance of the 'Replication Factor' (RF) setting chosen at cluster creation time?
- It can be changed per VM after deployment without restrictions
- It sets the number of data copies maintained and determines failure tolerance, and changing it requires a full data migration (Correct answer)
- It only affects virtual machine snapshots, not base VM data
- It determines the number of Prism Element instances running in the cluster
Correct 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.
