Nutanix Nutanix Certified Systems Engineer-Core (NCSE-Core 6.8) NCSE-Core Exam Dumps: Updated Questions & Answers (October 2025)

C. Inline compression:

Inline compression compresses data as it is written to the storage, reducing the amount of storage used and improving capacity utilization immediately. This is highly effective for reducing the storage footprint of a Splunk workload.

D. Capacity tier de-duplication:

Capacity tier de-duplication eliminates duplicate copies of data, further reducing the storage requirements. This is particularly useful for environments with repetitive data patterns, like log files generated by Splunk.

References:

Nutanix documentation and best practices on storage capacity optimization highlight the use of inline compression and de-duplication as key techniques for reducing storage usage and improving overall storage efficiency.

D. 2400 Users:

The number of users (2400) directly impacts the performance and scalability requirements of the Nutanix Files (AFS) deployment. High user counts can lead to increased demand for resources and necessitate additional nodes to ensure optimal performance and responsiveness.

References:

Nutanix Files (AFS) documentation and sizing guidelines highlight user count as a critical factor in determining the resource requirements for file workloads.

Erasure Coding (EC) Analysis:

Erasure Coding is a Nutanix feature that provides efficient storage utilization by distributing data across multiple nodes.

Write-cold Data Requirement:

Write-cold duration: Data must be 'write-cold' for a specific period before Erasure Coding can begin optimization.

Duration: The required duration for data to be considered 'write-cold' is 7 days.

Explanation:

Erasure Coding optimizes storage usage by encoding data across nodes. However, this process is applied to data that is infrequently accessed or modified.

The 7-day period ensures that the data is stable and not subject to frequent changes, making it suitable for EC optimization.

Outcome:

After 7 days of being 'write-cold', the data will be eligible for Erasure Coding, thereby optimizing storage efficiency while maintaining data resiliency.

References: For more details on Erasure Coding and its operational requirements, refer to Nutanix documentation on storage optimization and EC processes.

A. 1-Node and 2-Node Clusters:

Nutanix offers 1-node and 2-node cluster configurations, which are ideal for small remote locations with limited hardware requirements. These configurations are cost-effective and provide the necessary compute and storage resources for small workloads, addressing the cost concerns for the prospect’s remote sites.

D. AHV:

AHV (Acropolis Hypervisor) is included with Nutanix at no additional licensing cost, which can significantly reduce the total cost of ownership compared to environments that require separate hypervisor licenses (such as VMware vSphere). Highlighting the cost savings of using AHV can help address the prospect's concerns about pricing.

In the provided scenario, to meet the performance requirements and avoid any reduction in performance of the web servers, the systems engineer needs to adjust the CPU configuration. By switching to manual sizing and changing the CPUs of the node configuration to a dual 10 core model, the CPU resources will be sufficient to handle the workload without performance degradation​

Prism Central can forward logs to an external syslog server, enhancing the monitoring and troubleshooting capabilities for administrators. The two log modules capable of forwarding messages are:

API Audit

The API Audit log module captures and forwards logs related to API access and actions within the Nutanix environment. This is crucial for security and audit purposes, allowing administrators to track API usage and detect any unauthorized or suspicious activities.

Flow

The Flow log module deals with network monitoring and security within the Nutanix environment. It captures and forwards logs related to network traffic, flow policies, and security events, helping administrators to monitor network activities and enforce security policies effectively.

These modules can be configured in Prism Central to ensure that relevant log data is sent to external syslog servers for centralized logging and analysis.

Stargate is the CVM service responsible for providing storage to the hypervisor. It manages I/O operations, handles data distribution, replication, deduplication, compression, and other storage-related tasks. Stargate ensures that data is read and written efficiently, maintaining high performance and reliability within the Nutanix Distributed Storage Fabric (DSF).

When selecting a remote site to Prism, the valid targets include:

XI Cloud Services: This allows integration with Nutanix's cloud services for remote management and disaster recovery.

Physical Cluster: This option enables management and failover to another physical Nutanix cluster, ensuring high availability and business continuity​​.

The Curator service in a Nutanix cluster is responsible for distributing storage optimization tasks. This includes managing and distributing tasks such as disk balancing, proactive scrubbing, compression, deduplication, and erasure coding.

Task Distribution: Curator runs on every node and is controlled by an elected Curator Leader who is responsible for task and job delegation.

Scan Types: Curator performs full scans every six hours and partial scans every hour to ensure optimal storage performance and resource utilization.

Optimization Activities: The service ensures efficient data placement and storage utilization across the cluster.

Nutanix Bible: Provides an in-depth explanation of Curator and its role in the cluster​​.

To determine the minimum amount of HDD capacity required for the workload after converting thick provisioned disks to thin provisioned disks, we need to consider the active working set and the typical overhead for thin provisioning.

Current Capacity:

The prospect currently has 8500GB (8.5TiB) of provisioned capacity.

Active Working Set:

The total active working set for the cluster is determined to be 1TB.

Thin Provisioning:

Thin provisioning reduces the need for physical storage because it allocates storage on-demand rather than reserving the full capacity upfront.

Nutanix typically advises planning for additional overhead to accommodate metadata, snapshots, and potential growth.

Calculation:

The rule of thumb for thin provisioning overhead is approximately 2-3 times the active working set to ensure adequate capacity for metadata and additional data growth.

Using the higher end of the multiplier (3 times):

1TB (active working set)×3=3TB1 \text{TB (active working set)} \times 3 = 3 \text{TB}1TB (active working set)×3=3TB

Conclusion:

Therefore, the minimum HDD capacity required for the workload when thin provisioning is applied would be around 3.0TiB.
