NCA-6.10 Nutanix Certified Associate NCA v6.10 Questions and Answers

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.

When command-line access is unavailable, Nutanix administrators can use the Prism UI to generate an NCC (Nutanix Cluster Check) output. The steps are:

Configure the email settings inAlert Settingsunder the Prism UI.

Navigate to theHealth Dashboard, where the "Run Health Checks" option can be used.

Provide the administrator's email address to send the health report, which includes NCC outputs.

This method enables the administrator to share diagnostic information with Nutanix Support directly via email.

A. Run Health Checks in the Alert Dashboard and enter an email to send it to:Incorrect. Health Checks are run from the Health Dashboard, not the Alert Dashboard.

B. Configure email in Alert Settings and Run Health Checks in the Health Dashboard:Correct. This provides the requested NCC output when the command-line is inaccessible.

C. Run Health Checks in the Event Dashboard:Incorrect. Health Checks are not run from the Event Dashboard.

D. Configure email in Alert Settings and Run Health Checks in the Alert Dashboard:Incorrect, as this is not the correct location for Health Checks.

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.

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.

TheNutanix Moveutility is specifically designed for migrating VMs between hypervisors, including from ESXi to AHV. It automates the migration process while ensuring minimal downtime. Nutanix Move supports pre-migration assessments and automates data transfer and VM configuration for AHV.

A. Move:Correct, as it is the Nutanix tool for hypervisor migrations.

B. acli:Incorrect, as acli is used for command-line configuration and management within AHV, not migration.

C. Flow:Incorrect, as Nutanix Flow focuses on network security and micro-segmentation.

D. Ncli:Incorrect, as Ncli is a command-line utility for cluster management, not migration.

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.

TheReserved Capacityoption in a storage container explicitly reserves a portion of cluster storage for that container. This reservation reduces the amount of storage available for other containers. Reserved Capacity ensures that specific workloads have guaranteed storage resources, preventing resource contention or overcommitment.

Other options:

Advertised Capacity: Defines the storage limit displayed to users but does not reserve storage.

Erasure Coding: Optimizes storage efficiency but does not reduce available capacity.

Capacity Deduplication: Reduces space consumption by eliminating duplicate data but does not affect other containers' storage.

To create a VM template from an existing VM in Nutanix, the VM must be powered off. This ensures that the template is consistent and does not include any transient data or activity from the VM. Once the VM is powered off, the administrator can use the Prism UI to take a snapshot and designate it as a template.

A. Sysprep or Cloud-init script:These are optional for post-deployment configuration, not mandatory for creating a template.

B. The VM is powered on:This is incorrect, as the VM must be powered off.

C. Windows OS is installed:The OS type is irrelevant for creating a template.

D. The VM is powered off:Correct, as creating a template requires the VM to be in a powered-off state.

Applying tags to licenses to streamline future renewals is a task that can be completed inPrism Central Licensing. Prism Central provides centralized license management for clusters, enabling administrators to apply and manage license tags, which simplifies tracking and renewal tasks across multiple clusters. Here's how it works:

Prism Central Licensing Overview:Prism Central includes a dedicated licensing interface that provides a consolidated view of all licenses associated with your clusters. From this interface, administrators can categorize licenses using tags such as "Renewal-2025" or "Production," making it easier to identify and manage renewals or assignments.

Steps to Apply Tags in Prism Central:

Navigate toPrism Central > Settings > Licensing.

Select the desired license(s) from the list.

Use the "Tags" option to create or apply predefined tags to categorize these licenses.

Why Not Other Options?:

A. Clusters in the Support Portal: The Support Portal is primarily used for support-related tasks, such as managing cases or accessing documentation, and does not include license tagging capabilities.

B. License Inventory in the Support Portal: While the Support Portal allows you to view license inventory, it does not support operational tasks like tagging.

D. Prism Element Licensing: Prism Element is focused on managing licensing for individual clusters and lacks the centralized management and tagging functionality available in Prism Central.

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.

On a newly deployed AHV cluster, the default uplink bond type for the virtual switch (vs0) isBalance-SLB (Source Load Balancing). This configuration balances traffic across the uplinkinterfaces based on the source of the traffic, ensuring optimal usage of available network bandwidth without requiring LACP configuration on the physical switches.

TheRecycle Binin Nutanix clusters temporarily stores deleted VMs for 24 hours, allowing administrators to recover them if needed. This feature helps protect against accidental deletions by providing a grace period for recovery before permanent deletion occurs.

A. Stores the OpLog's most recent deleted data in case of a CVM failure:Incorrect, as the OpLog pertains to write operations, not VM deletion.

B. Keeps deleted VMs for 24 hours for recovery:Correct, as the Recycle Bin's purpose is temporary VM recovery.

C. Allows administrators to undo the last five actions:Incorrect, as there is no such feature for undoing multiple actions in Prism.

D. Centralizes the deleted data from the different VMs in the cluster:Incorrect, as the Recycle Bin is specifically for deleted VMs, not generalized data centralization.
