Nutanix NCA-6.10 Nutanix Certified Associate NCA v6.10 Exam Practice Test

When using ESXi as the hypervisor in a Nutanix cluster, the supported storage protocol for a datastore isNFS (Network File System). Nutanix exposes its distributed storage to ESXi hosts using NFS for VM storage. This protocol is simple to configure and provides high performance and reliability through Nutanix’s data services.

Other options:

iSCSI: Not typically used for ESXi datastores but can be utilized for specific use cases like external storage connectivity.

SMB: Not supported for ESXi datastores.

LVM: Logical Volume Management is not used in this context.

To prevent password access to the CVM for both thenutanixandadminuser accounts,Cluster Lockdownshould be enabled. Cluster Lockdown restricts SSH access to the Controller VM (CVM), effectively disabling password-based logins for enhanced security. Access is then managed through more secure means, such as console access or specific tools like Nutanix Support.

A. Cluster Lockdown:Correct, as this prevents SSH-based access to the CVM.

B. STIG:Incorrect, as STIG (Security Technical Implementation Guide) focuses on broader compliance measures.

C. RBAC Policy on PC:Incorrect, as RBAC (Role-Based Access Control) controls Prism Central permissions, not CVM access.

D. Data-at-Rest Encryption:Incorrect, as this secures stored data, not access credentials.

Non-migratable VMs in a Nutanix cluster typically include those with attached Volume Groups. This is because such VMs leverage direct-attached storage via iSCSI, which ties them to a specific host, preventing live migration to another host. Volume Groups provide block storage to applications, and the iSCSI protocol does not support live migration of such connections.

Here's a breakdown of the options:

A. VMs without NGT:Nutanix Guest Tools (NGT) are used for guest-level integration but do not affect VM migratability.

B. VMs marked as an Agent:This setting does not inherently make VMs non-migratable. It primarily affects roles and tasks within certain configurations.

C. Memory Overcommitted:While memory overcommitment can affect performance, it does not make VMs non-migratable. Nutanix AHV handles memory allocation dynamically.

D. VMs with attached Volume Groups:Correct answer, as the iSCSI connections used by Volume Groups are host-specific and cannot migrate seamlessly.

Nutanix Cloud Clusters (NC2)enables extending on-premises datacenters into public cloud environments, such as AWS or Azure. This solution allows administrators to seamlessly migrate workloads, scale operations, and manage resources across hybrid cloud environments using a unified control plane.

A. Nutanix Cloud Security:Incorrect, as this focuses on securing workloads in the cloud, not extending datacenters.

B. Nutanix Cloud Clusters:Correct, as NC2 enables hybrid cloud functionality by extending on-prem clusters into the public cloud.

C. Nutanix Kubernetes Engine:Incorrect, as this is used for container orchestration, not hybrid cloud extension.

D. Nutanix Data Services:Incorrect, as this refers to storage and data management capabilities.

Nutanix Distributed Storage Fabric (DSF) provides storage access to an ESXi hypervisor using theNFS (Network File System)protocol. DSF abstracts the underlying storage hardware and exposes storage as an NFS datastore to ESXi hosts. This integration enables high performance, data protection, and scalability while simplifying storage management.

Other options:

LVM: Not used in Nutanix storage.

iSCSI: Used for specific use cases, not the default protocol for ESXi.

SMB: Not supported for ESXi environments.

To license a new AOS-based cluster with no add-on packages, the appropriate license type isNutanix Cloud Infrastructure (NCI). The NCI license provides the fundamental capabilities required for Nutanix clusters, including:

Storage and data management.

Core virtualization features.

Compute resources for workloads.

NCI is designed for organizations that need the essential features of the Nutanix platform without additional add-ons such as database services (NDB) or advanced storage options (NUS).

Other options:

A. Nutanix Cloud Manager (NCM):Focuses on management capabilities for multi-cloud and operational tasks, not core infrastructure licensing.

C. Nutanix Unified Storage (NUS):Specifically provides unified file and object storage capabilities, not relevant for a base AOS cluster.

D. Nutanix Database Service (NDB):A dedicated licensing tier for database management features.
