NCSE-Core Exam Dumps - Nutanix Certified Systems Engineer-Core (NCSE-Core 6.8)

When using the Sizer in Automatic mode, it can provide various configurations based on the specified workload and capacity requirements. The following configurations are possible:

6x NX-8055-G7:

Each node has 2 x 7.68TB SSDs and 10x 6TB HDDs.

This configuration balances high-performance SSDs with large-capacity HDDs, suitable for mixed workload environments.

4x NX-1075S-G7 + 4x NX-8035-G7:

NX-1075S-G7 nodes have 4x 3.85TB SSDs each.

NX-8035-G7 nodes have 6x 3.84TB SSDs each.

This combination provides high SSD storage capacity across different node types, optimized for performance-intensive workloads.

Nutanix Foundation is the tool used for imaging nodes that are either bare metal or require a different hypervisor. Foundation is designed for bootstrapping the imaging and deployment of Nutanix clusters. It installs the desired version of the Acropolis Operating System (AOS) and the hypervisor of choice. By default, Nutanix nodes ship with AHV pre-installed, but Foundation can be used to re-image the nodes with a different hypervisor if required.

Understanding Citrix Desktop Creation:

Citrix desktop creation involves provisioning and managing virtual desktops, which is critical for deploying VDI (Virtual Desktop Infrastructure) environments.

Capabilities Supported on Nutanix AHV:

Provisioning Service (PVS):

Explanation: Citrix Provisioning Services streamlines desktop and server management by provisioning desktops from a single shared image.

Support on AHV: Nutanix AHV supports Citrix PVS for efficient desktop creation and management.

Reclaiming Licenses (Including License Renewal)

You can reclaim and optionally re-apply licenses for nodes in your clusters:

You must reclaim licenses when you plan to destroy a cluster. First reclaim the licenses, then destroy the cluster. You do not need to reclaim Starter licenses. These licenses are automatically applied whenever you create a cluster, including after you have destroyed a cluster.

Return licenses to your inventory when you remove one or more nodes from a cluster. Also, if you move nodes from one cluster to another, first reclaim the licenses, move the nodes, then re-apply the licenses.

You can reclaim licenses for nodes in your clusters in cases where you want to make modifications or downgrade licenses. For example, applying an Ultimate license to all nodes in a cluster where some nodes are currently licensed as Pro and some nodes are licensed as Ultimate. You might also want to transition nodes from Ultimate to Pro licensing.

You must reclaim licenses when you renew licenses. First reclaim the expired licenses, then apply new licenses.

A prospect evaluating Nutanix for a large number of Oracle RAC deployments, prioritizing time to deployment and utilizing an in-house self-service tool, would benefit most from Nutanix's REST API capabilities. Here is a detailed explanation:

Requirement Analysis:The prospect needs a solution that allows rapid deployment of Oracle RAC environments and integrates with their existing self-service deployment tool. This means the feature should support automation and programmatic control.

Feature Analysis:

Calm: While Nutanix Calm can orchestrate and automate application deployments, including complex multi-tier applications, the existing self-service tool of the prospect may make Calm redundant for this specific need.

Xtract for Databases: This tool assists in migrating databases to Nutanix but is not directly involved in deploying new Oracle RAC instances.

ABS (Acropolis Block Services): ABS provides block storage services to external physical and virtual machines but is not focused on deployment automation.

REST API: Nutanix’s REST API offers extensive programmatic control over various functions, including provisioning, managing, and configuring Nutanix environments. It allows the integration of custom tools to automate and expedite deployments effectively.

Conclusion:Given the requirement for rapid deployment through an existing self-service tool, Nutanix REST API is the most appropriate feature to discuss. It provides the necessary flexibility and integration capabilities for automated deployments.

For a prospect interested in evaluating Nutanix at no cost for a few months using existing test hardware:

Requirement Analysis:

The prospect wants a free evaluation.

They intend to use their existing hardware.

Their focus is on experiencing platform management rather than performance.

Feature Analysis:

Nutanix NX POC: Provides a proof of concept using Nutanix hardware, which might not align with the prospect's desire to use existing hardware.

Nutanix Community Edition (CE): A free, fully functional version of Nutanix AOS that can be installed on existing hardware. It is intended for non-production use and allows users to experience the management features of Nutanix.

Nutanix Go: A subscription-based service providing Nutanix hardware and software, not suitable for a no-cost evaluation.

Nutanix Test Drive: Offers a short-term, hands-on experience in a hosted environment, but does not allow for an extended evaluation using the prospect's hardware.

Conclusion: Nutanix Community Edition is the best option for the prospect as it allows a no-cost, extended evaluation using their existing hardware and focuses on platform management capabilities.

Current Environment Analysis:

The existing AHV cluster has 7 NX-3060-G6 nodes with Intel Skylake processors.

These nodes are distributed across two blocks.

The customer needs to add three more NX-3060-G7 nodes with Intel Cascade Lake processors.

Objective:

Efficiently utilize additional resources by integrating new nodes into the existing infrastructure.

Recommendations:

Expand the existing cluster: The goal is to enhance resource utilization and maintain cluster simplicity by adding the new nodes to the current cluster.

Add a new block populated with the three additional nodes: This approach provides several benefits:

It ensures the new nodes are integrated into the existing management and operational framework.

It leverages the existing network and storage configurations, minimizing setup complexities.

By adding a new block, the existing two blocks remain unchanged, maintaining their current configuration and workloads.

Implementation:

Order and prepare the new nodes: Ensure that the three additional NX-3060-G7 nodes are ready for deployment.

Add the new block to the existing cluster:

Physically rack and connect the new block with the three NX-3060-G7 nodes.

In the Nutanix Prism interface, initiate the process to add the new block to the existing cluster.

The cluster expansion process will automatically incorporate the new nodes into the existing cluster, ensuring seamless integration.

Outcome:

The customer will achieve an efficient expansion of their AHV cluster, utilizing the new resources effectively.

This method ensures minimal disruption and maintains operational consistency across the cluster.

References: For further details on cluster expansion and node addition processes, refer to the Nutanix documentation on cluster management and node integration.

Understanding Critical Requirements:

For critical business operations, high availability, performance, and redundancy are essential to ensure minimal downtime and robust performance.
