NCA-6.10 Exam Dumps - Nutanix Certified Associate (NCA) Questions and Answers

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.

The correct answer isD. Flow Virtual Networking (FVN).

Flow Virtual Networking (FVN)is a Nutanix solution that enablesadvanced network virtualization, including:

VPCs (Virtual Private Clouds)

Overlapping IP address spaces

Self-service network provisioning

Multi-tenancy support

Microsegmentation

FVN abstracts physical networking and allows tenants to manageisolated logical networks, providing cloud-like networking capabilities directly integrated with AHV.

Clarifications:

A. Nutanix Kubernetes Platform (NKP):Orchestrates containers; does not provide virtualized network infrastructure.

B. Flow Network Security:Focuses onmicrosegmentationandpolicy enforcement, not on VPC or L3 abstraction.

C. Nutanix Database Service (NDB):Manages DBaaS; not related to networking.

Excerpt: “Flow Virtual Networking provides VPCs, overlapping IPs, and self-service networking capabilities for secure multi-tenancy in Nutanix AHV clusters.”

Answer: D

The default admin session logout time in Nutanix is15 minutes. If no activity is detected within this time, the session is automatically logged out for security reasons. This timeout can be adjusted in the system settings if needed, depending on organizational requirements.

Nutanix AHV (Acropolis Hypervisor) supports integrated IP address management (IPAM) as a built-in feature. IPAM allows administrators to dynamically allocate and manage IP addresses for VMs within a network segment. This functionality simplifies network management by automating the assignment of IPs without relying on external DHCP servers.

A. ESXi:Incorrect, as ESXi does not include built-in IPAM.

B. Hyper-V:Incorrect, as Hyper-V lacks integrated IPAM functionality.

C. AHV:Correct, as AHV has built-in IPAM for automated IP address allocation.

D. XenServer:Incorrect, as XenServer does not support integrated IPAM.

The correct answer isC. It must have the same hypervisor as the other nodes in the cluster.

When adding astorage-only (SO) nodeto a Nutanix cluster:

It mustrun the same hypervisoras the existing nodes.

The SO node doesnot host VMsbut participates in thestorage layerto increase capacity and performance.

Nutanix currentlydoes not support mixed hypervisors(e.g., combining AHV with ESXi) within the same cluster, even for storage-only nodes.

Clarifications:

A & B:Neither Nutanix Files nor Objects are required for adding storage-only nodes.

D:Cross-hypervisor configuration is unsupported at the cluster level.

Official Reference:

Nutanix Hardware Administration Guide – Storage-Only Node Requirements

Excerpt: “All nodes in a cluster, including storage-only nodes, must run the same hypervisor type.”

Answer: C

The correct answer isA. br0.

InAHV (Acropolis Hypervisor),br0is thedefault native Linux bridgecreated on each hypervisor host. It is used for VM traffic and external communication. AHV leveragesOpen vSwitch (OVS)to manage virtual networking, but the bridge is exposed as br0 in the host's network configuration.

Key points:

br0connects VM virtual NICs (vNICs) to the physical network via the host's uplinks.

It is pre-configured during Foundation or cluster deployment.

virbr0is typical in KVM environments but isnot usedin AHV.

Official Reference:

Nutanix AHV Networking Guide

Nutanix KB #2027 – AHV Host Networking

Excerpt: “AHV uses br0 as the default bridge on the host, configured by Open vSwitch for guest VM networking.”

Answer: A

Nutanix Metro Availability provides the best Recovery Time Objective (RTO) because it enables synchronous replication between two sites. In the event of a failure at one site, VMs can be instantly restarted on the other site with minimal disruption. This setup ensures zero data loss and near-instantaneous recovery.

A. Async:Provides high RPO (Recovery Point Objective) but has a longer RTO compared to synchronous replication methods.

B. Availability Zone:This term refers to a general site setup, not specific to recovery objectives.

C. Metro Availability:Correct, as it uses synchronous replication for near-zero RTO.

D. NearSync:Provides better RPO than Async but does not match the RTO of Metro Availability.

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.

The correct answer isA. NearSync Replication.

Key Concepts from Official Nutanix Documentation:

Nutanix supports various types of data replication methods depending on the Recovery Point Objective (RPO), Recovery Time Objective (RTO), and the latency between the sites.

Metro Availabilityrequires a maximum latency of<5ms RTTand is used forzero RPO synchronous replication. Since the given latency is 10ms,Metro Availability is not supportedin this case.

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.
