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

Understanding the Context:

The project to migrate to the public cloud was largely unsuccessful, indicating underlying issues that need to be identified.

Effective Open-Ended Questions:

What challenges triggered the public cloud initiative?:

Explanation: This question helps understand the initial pain points and motivations for the migration attempt, providing insight into what problems the company was trying to solve.

A prospective customer wants to build a private cloud and provision workloads across multiple public cloud providers but lacks the time and skillset for on-premises infrastructure management. Here is the detailed explanation of the features qualifying this project as a Nutanix opportunity:

Requirement Analysis:

Private cloud setup.

Provisioning across multiple public clouds.

Limited time and skillset for managing on-premises infrastructure.

Feature Analysis:

Flow: Provides network micro-segmentation and security, but does not directly address cloud management or simplicity in operations.

Calm: Nutanix Calm provides application automation and lifecycle management, enabling easy provisioning and management of applications across private and public clouds.

Cloud Connect: Facilitates backup and recovery to public clouds, not specifically for provisioning and ongoing management.

All Flash Nodes: Improves performance but does not address cloud management or ease of use.

Prism 1-Click operations: Offers simplified, automated management and operational tasks through a single interface, reducing the complexity and time required for infrastructure management.

Conclusion:Nutanix Calm and Prism 1-Click operations are the most relevant features as they enable seamless multi-cloud provisioning and management while simplifying the management of on-premises infrastructure.

To migrate database workloads from a 3-tier vSphere architecture to a Nutanix cluster while maintaining customer experience and minimizing costs, it is crucial to focus on maintaining similar processor speeds. Here’s a detailed explanation:

Workload Analysis:

The current environment consists of hosts with 256G RAM and Broadwell 2.8 GHz 12-core processors.

The largest database VM uses 64G of memory, and some databases are single-threaded but have acceptable performance.

Processor Consideration:

Database performance, especially for single-threaded workloads, is highly dependent on the CPU's clock speed.

Using processors with similar speed ensures that the performance characteristics remain consistent, minimizing the risk of performance degradation.

Avoiding Performance Bottlenecks:

Matching the CPU speed helps maintain the current acceptable performance levels.

This approach is more cost-effective than upgrading to higher-speed processors or increasing memory excessively.

Cluster Configuration:

Ensuring the new Nutanix cluster has processors with similar clock speeds to the existing environment will provide a smooth transition.

This consistency will also help in minimizing the need for extensive re-optimization or re-tuning of the databases post-migration.

Nutanix Security Configuration Management Automation (SCMA) reduces the effort required to assess and maintain the security of Nutanix infrastructure by automating security compliance checking and remediation. SCMA continuously monitors the configuration of Nutanix CVMs and AHV hosts against documented security baselines (e.g., STIGs). If any non-compliance is detected, SCMA automatically remediates the settings to align with the defined security standards without requiring manual intervention from administrators. This ensures that the cluster remains compliant with security policies throughout its lifecycle, thereby significantly reducing the effort and overhead associated with security management.

B. Data Locality:

Nutanix's data locality feature ensures that data is always written and read from the local storage of the node where the VM is running. This minimizes latency and provides consistent performance, which addresses the unpredictable storage performance and latency spikes the prospect is experiencing.

By keeping data local to the VM, Nutanix reduces the dependency on the network for storage operations, resulting in improved and predictable performance, especially during peak utilization.

To maintain optimal metadata balance and data availability, and to meet the requirements for storage capacity, memory, and CPU cores, the recommended configuration should align closely with the existing node configurations while providing the necessary resources.

A. 2x NX-3060-G5 - 2x E5-2620v4 processors, 128GB RAM, 2x 960GB SSDs, 4x 2TB HDDs:

Adding two additional NX-3060-G5 nodes with the same specifications as the existing nodes ensures uniformity and maintains metadata balance and data availability.

This configuration provides enough additional storage capacity, memory, and CPU cores to accommodate the new workloads.

The certified configuration for Oracle Linux and Oracle VM via iSCSI uses Nutanix Acropolis Block Services (ABS). ABS allows Nutanix storage to be presented as iSCSI targets to external servers, enabling the use of Nutanix storage in conjunction with Oracle environments.

This feature ensures high performance and reliability for Oracle workloads while leveraging Nutanix’s advanced storage capabilities.

Nutanix documentation and the Oracle HCL list provide details on certified configurations and the use of ABS for integrating Nutanix storage with Oracle environments.

C. Expand the cluster by adding an additional node:

Demonstrating the ease of expanding the Nutanix cluster by adding an additional node showcases the scalability and simplicity of Nutanix’s hyperconverged infrastructure. This is a critical success criterion for customers looking for a solution that can grow with their needs.

D. Use a single interface to manage and monitor the full stack:

One of Nutanix’s key advantages is the ability to manage and monitor the entire infrastructure stack from a single interface, Prism. This feature simplifies management and reduces operational overhead, which aligns with the customer’s requirement for an “All in One” solution.
