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

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.

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.

To rerun only the health checks that previously failed or issued warnings, the administrator can select theOnly Failed and Warning Checksoption in Prism Element. This targeted approach helps verify that resolved issues have been addressed without rerunning all checks unnecessarily.

Steps:

Navigate toPrism Element > Health > NCC Checks.

Filter forOnly Failed and Warning Checksand rerun them.

Other options:

A. Run LCM Pre-Upgrade: Runs pre-upgrade checks, not related to health check validation.

B. Runncc health_checks run_all: Executes all checks, not just failed ones.

C. Select Run Check for each check worked: Requires manual execution for each check.

To allow Nutanix Support to gather logs automatically without requiring manual intervention, the administrator should enablePulse. Pulse is a telemetry service that collects and sends system health, log, and usage data to Nutanix Support securely.

Steps:

Navigate toPrism Central > Settings > Pulse.

Enable the service and configure as required for your environment.

Other options:

Self-Service: Refers to role-based access for users, unrelated to log collection.

Proxy Server: Used for network communication, not log gathering.

NKP: Refers to Nutanix Cluster Protocol, unrelated to telemetry.

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.

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.

TheData Protectionfeature in Prism Element provides built-in disaster recovery capabilities by enabling asynchronous replication between Nutanix clusters. With a latency of 30ms between the two sites, asynchronous replication can ensure that data is replicated efficiently while adhering to recovery point objectives (RPO). The administrator can configure Protection Domains and Replication Targets to set up DR between the clusters.

A. Recovery Plan:Incorrect, as Recovery Plans are part of Prism Central for orchestrated failover, not Prism Element.

B. Protection Policies:Incorrect, as these are defined under Prism Central.

C. Data Protection:Correct, as it enables disaster recovery via replication configurations in Prism Element.

D. Metro Cluster:Incorrect, as Metro Cluster requires low latency (<5ms) and is not suitable for a 30ms latency scenario.

Fordark site clusters, theNutanix Compatibility Bundlemust be downloaded prior to running LCM Inventory or updates. This bundle contains the necessary metadata and software binaries to perform inventory collection and upgrades in environments without internet connectivity.

A. Nutanix Foundation:Incorrect, as Foundation is used for initial deployments, not for LCM updates.

B. Nutanix Compatibility Bundle:Correct, as it contains the necessary files for offline LCM operations.

C. Nutanix Prism Central:Incorrect, as this does not pertain to offline updates.

D. Nutanix Foundation Platform:Incorrect, as this is not required for LCM Inventory or updates.

To verify if the cluster is currently protected from potential data loss due to a component failure, the administrator should check theData Resiliency Status widgeton the Prism Element Home dashboard. This widget provides real-time information about the cluster's resiliency status, including warnings or errors about data redundancy or protection.

Other options:

A. Select the gear icon and then select Pulse:Pulse is used for telemetry data, not data resiliency status.

B. Click on Home and then Alerts:Alerts show specific issues but do not directly indicate the overall resiliency status.

D. Navigate to the Health dashboard:The Health dashboard provides detailed health checks but does not display the current resiliency status.

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.

Nutanix licensing is available in three tiers:

Starter: Entry-level features for basic virtualization and storage requirements.

Pro: Advanced features such as data protection and disaster recovery.

Ultimate: Comprehensive feature set, including advanced analytics and automation.

This tiered approach enables administrators to choose the appropriate license level based on their business requirements.

For a Veeam Backup appliance using iSCSI to connect to an AHV-based Nutanix cluster, aData Services IP (DSIP)must be configured. The DSIP is a virtual IP that allows external systems to communicate with Nutanix storage using protocols such as iSCSI. This ensures seamless connectivity between Veeam and the Nutanix cluster.

A. Network Segmentation:While network segmentation is important for security, it is not specifically required for iSCSI connectivity.

B. Nutanix Objects:Nutanix Objects is used for object storage, not iSCSI connectivity.

C. Prism Central:Prism Central is used for multi-cluster management but is not involved in configuring iSCSI.

D. Data Services IP:Correct, as it enables external systems to connect via iSCSI.
