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

B. N+1:

Based on the sizing scenario and the configuration shown in the exhibit, the Failover option selected is "Standard (N+1)."

This indicates that the cluster is configured to provide N+1 resiliency, where the system can handle the failure of one node by having an additional node available to take over.

This level of resiliency is common in environments where a balance between cost and availability is required.

References:

Nutanix Sizer tool and Nutanix documentation provide detailed explanations on configuring clusters with different levels of resiliency, including N+1.

A. Gartner Magic Quadrant:

The Gartner Magic Quadrant is a well-recognized industry report that evaluates technology vendors based on their completeness of vision and ability to execute. It is a credible source that highlights Nutanix’s position as a leader in the hyperconverged infrastructure (HCI) market.

Highlighting Nutanix’s leadership position in the Gartner Magic Quadrant can help address the management’s concerns about Nutanix’s market presence and reinforce its credibility as a major player in the HCI space.

C. Adding Storage Only nodes:

Nutanix allows for the addition of storage-only nodes to a cluster. These nodes provide additional storage capacity without adding compute resources, which is a cost-effective way to increase storage for data retention and compliance purposes.

This capability allows the prospect to scale storage independently of compute, addressing concerns about data retention costs by adding capacity as needed without the overhead of additional CPU and memory resources.

A. 6x NX-3060-G6 (6x 1920GB SSDs per node):

This configuration is valid in Automatic mode as it meets the criteria for SSD storage and node count.

C. 6x NX-8150-G5 (4x 1920GB SSD + 20x 2TB HDD per node):

This configuration is also valid as it includes a mix of SSDs and HDDs, fitting the requirements for hybrid storage configurations in Automatic mode.

References:

The Nutanix Sizer tool’s automatic mode settings ensure that configurations meet performance and capacity requirements while adhering to the specified storage and node configurations.

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 Documentation: Further details on the operations and management of Curator tasks.

Customer Requirement:

Data-at-Rest-Encryption for all data.

License Options:

Pro with the Encryption SKU: This option allows customers to add encryption capabilities to the Pro tier.

Ultimate: This tier includes built-in encryption features, providing comprehensive data security.

Explanation:

Pro with the Encryption SKU: Customers using the Pro tier can enhance their security by purchasing the additional Encryption SKU, which enables Data-at-Rest-Encryption.

Ultimate: This tier natively includes encryption, offering an all-in-one solution for customers requiring high levels of data security without additional SKUs.

Outcome:

Customers can choose either of these two licensing options to meet their Data-at-Rest-Encryption requirements, ensuring that all their data is securely encrypted.

References: For detailed licensing information and encryption capabilities, refer to Nutanix documentation on security features and licensing tiers.

When sizing a hybrid cluster to replace an existing IT test and development environment, the systems engineer (SE) requires the following additional items besides the aggregate vCPU and RAM requirements:

Working Data Set:

Understanding the size of the working data set helps determine the amount of active data that needs to be stored and accessed frequently. This information is crucial for optimizing the performance and ensuring that sufficient resources are allocated for the active workloads.

Storage Capacity:

The total storage capacity required for the cluster must be assessed to ensure that the new environment can accommodate all the data from the existing cluster. This includes not only the active data but also additional capacity for future growth, snapshots, backups, and other storage needs.

C. ABS (Acropolis Block Services):

Acropolis Block Services (ABS) enables Nutanix storage to be used by external servers, providing the performance and benefits of Nutanix’s distributed storage fabric while allowing the customer to continue using their existing investment in Oracle servers.

ABS allows the integration of all-flash storage with the existing Oracle environment, addressing the prospect's preference for all-flash arrays while leveraging Nutanix’s advanced storage capabilities.

References:

Nutanix documentation on ABS describes its features and benefits, particularly its ability to integrate Nutanix storage with external servers and support high-performance applications like Oracle databases.
