NCA-6.10 Questions and Answers

In a cluster configured with Redundancy Factor 3 (RF3), the system ensures that data is replicated across at least three nodes to tolerate the failure of two nodes. During an AHV upgrade, Nutanix only placesone node at a timeinto maintenance mode, even in an RF3 configuration, to minimize the impact on data redundancy and cluster operations.

A. 1:Correct, as AHV upgrades proceed node by node in RF3.

B. 2, C. 3, D. 4:These options are incorrect, as only one node is upgraded at a time regardless of RF3.

Nutanix Support case priority levels are defined as follows:

P1 (Critical):The system is down or severely impacted, requiring immediate attention.

P2 (High):The system is available but experiencing issues that directly impact productivity or operations.

P3 (Medium):The system is functioning, but there are non-critical issues or questions.

P4 (Low):General questions or requests that do not impact system performance.

The scenario described matchesP2, where the system is available but productivity is directly affected by the issue.

The feature that ensures VMs automatically power on in a specific order at the DR site during a disaster is aRecovery Plan. Recovery Plans are part of Nutanix’s DR functionality and allow administrators to define startup sequences, dependencies, and priorities for VMs during failover scenarios.

Steps:

Create a Recovery Plan in Prism Central under the DR section.

Configure the VM power-on sequence and dependency rules.

Test the Recovery Plan to ensure it operates as intended.

Replication Factor (RF) defines the number of copies of data stored in a Nutanix cluster. RF2 ensures two copies of data, and RF3 ensures three copies. This redundancy allows the system to maintain data integrity and recoverability even in the event of hardware failures.

A. It limits the scope of hardware failures during recovery operations:Incorrect, as RF focuses on data replication, not limiting failure scopes.

B. It ensures that multiple copies of data are available for recovery:Correct, as RF directly relates to data redundancy and recovery capabilities.

C. It accelerates data transfer to remote backup sites:Incorrect, as RF does not affect remote backup speed.

D. It reduces the need for offsite backup solutions:Incorrect, as RF works within the cluster, not as a replacement for offsite backups.

To create a VM-VM Anti-Affinity Policy ensuring VMs are not placed on the same hypervisor,Prism Centralis required. Anti-affinity policies are cluster-wide configurations managed through Prism Central’s policy-based interface, enabling placement rules to distribute workloads effectively.

Steps:

Navigate toPrism Central > Policies.

Create a new Anti-Affinity Policy.

Select the VMs and configure the policy to ensure separation.

When multiple alert policies are applied to an entity, Nutanix uses a hierarchical approach. Policies applied toan entity type within a categorytake precedence. For example:

If a category (e.g., "Production") has policies applied to entities like VMs, and the entity matches that category, the category-specific policy will override general policies.

This prioritization allows administrators to fine-tune alert policies for specific workloads or environments.

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.

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.

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.

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.
