Nutanix NCA-6.10 - Nutanix Certified Associate NCA v6.10

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. Large-scale, read heavy workloads.

NFS on Objectsis a Nutanix feature allowingNFS clients to interact with Nutanix Objects (S3-compatible object storage)by exposing object buckets viaNFS v3 protocol. This is ideal for workloads that require:

Large-scale access to unstructured data

High read concurrency

Cost-effective storage for infrequently changed files

Best Use Case:

Backup archives, analytics workloads, image repositories, or video streaming systems withread-heavy profiles.

Clarifications:

A (EUC workloads):Typically require fast, low-latency block storage (e.g., vDisks).

B (Transitory FS):Better suited for file services like Nutanix Files.

D (Frequent updates):Not ideal for object storage via NFS; performance will degrade under frequent write operations.

Official Reference:

Nutanix Documentation Portal – Objects and NFS

Excerpt: “NFS on Objects is best suited for large-scale, read-heavy use cases where file system semantics are needed on top of object-based storage.”

In aRedundancy Factor 3 (RF3)cluster,5 copies of the metadataare maintained to ensure data durability and cluster resiliency. RF3 provides fault tolerance against up to two simultaneous failures (e.g., node or disk failures) and requires more metadata copies to achieve this level of protection.

Other redundancy factors:

RF2maintains 3 copies of metadata.

RF3 requires at least 5 metadata copies to protect against additional failures.

For a cluster withRedundancy Factor 2 (RF2), at least4 nodesare required to configure Erasure Coding. Erasure Coding (EC) distributes data and parity across nodes to improve storage efficiency while maintaining data protection. RF2 requires a minimum of 4 nodes to ensure sufficient space for data and parity distribution.

Other options:

3 nodes: Insufficient for EC with RF2.

5 and 6 nodes: Can support EC, but the minimum requirement is 4.

TheTasksdashboard in Prism Element provides detailed visibility into the progress of all ongoing and completed tasks, including Life Cycle Manager (LCM) updates. Administrators can monitor the step-by-step status of LCM operations, track failures, and identify bottlenecks.

A. Analysis:Incorrect, as this is used for performance monitoring, not task progress.

B. Tasks:Correct, as it displays detailed progress for updates and other operations.

C. Hardware:Incorrect, as this focuses on the state and configuration of hardware components.

D. Alerts:Incorrect, as this shows system alerts and issues, not detailed task progress.

In Prism Central, theImagessection within the Compute and Storage tab is used to upload ISO files, including Windows installation ISOs. Once uploaded, these images can be used to create or install VMs across clusters managed by Prism Central.

A. Catalog Items:Incorrect, as this is used to manage preconfigured application templates.

B. Templates:Incorrect, as this is used for VM templates, not ISO uploads.

C. Images:Correct, as it allows uploading and managing ISO and disk images.

D. OVAs:Incorrect, as this pertains to importing virtual appliances, not ISO files.

The correct answer isD. Every 24 hours.

In NutanixLife Cycle Manager (LCM), when theLCM Auto Inventoryfeature is enabled, the system performsautomatic inventory scansof the cluster's hardware and software components. By default, thisauto-inventory runs every 24 hoursto keep track of firmware, software versions, and available updates.

Clarifications:

The frequency isnot user-configurablefrom the Prism UI.

It ensuresaccurate detection of upgrade eligibilityand component compliance.

The admin can alsorun an inventory manuallyat any time.

Prism UI Navigation Path:

Settings > LCM > Auto Inventory(toggle enabled)

Official Reference:

Nutanix LCM Guide – Auto Inventory Section

Excerpt: “When Auto Inventory is enabled, LCM automatically performs inventory every 24 hours.”

Answer: D

When configuring a physical network switch in Prism Element,SNMP Configurationis required to enable monitoring and communication between the Nutanix cluster and the network switch. SNMP (Simple Network Management Protocol) is used to gather metrics and detect issues such as link failures or performance bottlenecks, ensuring the cluster operates efficiently with the physical network infrastructure.

To run a full health check in Prism Element, the administrator should first select theActionsmenu. From there, the administrator can choose to execute health checks for the entire cluster or specific components. This ensures a comprehensive evaluation of the cluster’s health.

Other options:

Scheduled: Refers to predefined or automated health checks.

Checks: Displays the list of checks but doesn’t initiate them.

Failed: Filters checks based on their status but doesn’t start a new check.

When a Nutanix cluster alert occurs, indicating maintenance mode issues, the most likely cause is that another node in the cluster is already in maintenance mode. Nutanix clusters enforce restrictions to prevent more than one node from entering maintenance mode simultaneously. This ensures the cluster can maintain resiliency and availability, adhering to the redundancy factor (RF) policy.

If another node is already in maintenance mode, the cluster cannot afford to have additional nodes enter maintenance without compromising data and service availability.
