Nutanix Nutanix Certified Professional (NCP) NCP-US-6.5 New Questions

Nutanix Objects, a component of Nutanix Unified Storage (NUS), provides an S3-compatible object storage solution. It is deployed as a set of virtual machines (Object Store Service VMs) running on the Nutanix cluster’s hypervisor (AHV or ESXi). The resource allocation for these VMs, including the maximum number of vCPUs per node, is specified in the Nutanix Objects documentation to ensure optimal performance and resource utilization.

According to the official Nutanix documentation, each Object Store Service VM is limited to a maximum of 8 vCPUs per node (AHV or ESXi). This constraint ensures that the object storage service does not overburden the cluster’s compute resources, maintaining balance with other workloads.

Option C: Correct. The maximum number of vCPUs for Nutanix Objects per node is 8.

Option A (12), Option B (16), and Option D (10): Incorrect, as they exceed or do not match the documented maximum of 8 vCPUs per node.

Exact Extract from Nutanix Documentation:

From the Nutanix Objects Administration Guide (available on the Nutanix Portal):

“Each Object Store Service VM deployed on an AHV or ESXi node is configured with a maximum of 8 vCPUs to ensure efficient resource utilization and performance. This limit applies per node hosting the Object Store Service.”

Additional Notes:

The vCPU limit is per Object Store Service VM on a given node, not for the entire Objects deployment. Multiple VMs may run across different nodes, but each is capped at 8 vCPUs.

The documentation does not specify different limits for AHV versus ESXi, so the 8 vCPU maximum applies universally.

Nutanix Data Lens, a service integrated with Nutanix Unified Storage (NUS), provides data governance, analytics, and ransomware protection for Nutanix Files. Enabling Data Lens for a file server involves configuring the service to monitor the file server’s shares. If the administrator is unable to enable Data Lens, there may be a configuration or compatibility issue with the file server.

Analysis of Options:

Option A (The file server has been cloned): Correct. Cloning a file server (e.g., creating a duplicate file server instance via cloning in Nutanix) is not a supported configuration for Data Lens. Data Lens relies on a unique file server identity to manage its metadata and analytics. If the file server has been cloned, Data Lens may fail to enable due to conflicts in identity or metadata, as the cloned file server may not be properly registered or recognized by Data Lens.

Option B (SSR is enabled on the file server): Incorrect. Self-Service Restore (SSR) is a feature in Nutanix Files that allows users to recover previous versions of files in SMB shares. Enabling SSR does not affect the ability to enable Data Lens, as the two features are independent and can coexist on a file server.

Option C (The file server is in a Protection Domain): Incorrect. A Protection Domain in Nutanix is used for disaster recovery (DR) of VMs or Volume Groups, not file servers directly. Nutanix Files uses replication policies (e.g., NearSync) for DR, not Protection Domains. Even if the file server is part of a replication setup, this does not prevent Data Lens from being enabled.

Option D (The file server has blacklisted file types): Incorrect. Blacklisting file types in Nutanix Files prevents certain file extensions from being stored on shares (e.g., for security reasons). However, this feature does not affect the ability to enable Data Lens, which operates at a higher level to analyze file metadata and user activity, regardless of file types.

Why Option A?

Cloning a file server creates a duplicate instance that may not be properly registered with Data Lens, leading to conflicts in identity, metadata, or configuration. Nutanix documentation specifies that Data Lens requires a uniquely deployed file server, and cloning can cause issues when enabling the service, making this the most likely cause of the administrator’s difficulty.

Exact Extract from Nutanix Documentation:

From the Nutanix Data Lens Administration Guide (available on the Nutanix Portal):

“Data Lens requires a uniquely deployed file server to enable its services. Cloning a file server is not supported, as it may result in conflicts with Data Lens metadata and configuration. If a file server has been cloned, Data Lens may fail to enable, and the file server must be redeployed or re-registered to resolve the issue.”

Self-Service Restore (SSR) is a feature that allows individual users to restore files and folders hosted in Files without requiring administrator intervention. SSR can be enabled on a per-share or per-export basis, and users can access the snapshots of their data through a web portal or a Windows client application1.

Workload optimization in Nutanix Files, part of Nutanix Unified Storage (NUS), refers to the process of tuning the Files deployment to handle specific workloads efficiently. This involves scaling resources to match the workload demands, and the primary entity for optimization is the number of File Server Virtual Machines (FSVMs).

Analysis of Options:

Option A (Protocol): Incorrect. While Nutanix Files supports multiple protocols (SMB, NFS), workload optimization is not directly based on the protocol. Protocols affect client access, but optimization focuses on resource allocation.

Option B (File type): Incorrect. File type (e.g., text, binary) is not a factor in workload optimization for Files. Optimization focuses on infrastructure resources, not the nature of the files.

Option C (FSVM quantity): Correct. Nutanix Files uses FSVMs to distribute file service workloads across the cluster. Workload optimization involves adjusting the number of FSVMs to handle the expected load, ensuring balanced performance and scalability. For example, adding more FSVMs can improve performance for high-concurrency workloads.

Option D (Block size): Incorrect. Block size is relevant for block storage (e.g., Nutanix Volumes), but Nutanix Files operates at the file level, not the block level. Workload optimization in Files does not involve block size adjustments.

Why FSVM Quantity?

FSVMs are the core entities that process file operations in Nutanix Files. Optimizing for a workload (e.g., high read/write throughput, many concurrent users) typically involves scaling the number of FSVMs to distribute the load, adding compute and memory resources as needed, or adjusting FSVM placement for better performance.

Exact Extract from Nutanix Documentation:

From the Nutanix Files Administration Guide (available on the Nutanix Portal):

“Workload optimization in Nutanix Files is achieved by adjusting the number of FSVMs in the file server. For high-performance workloads, you can scale out by adding more FSVMs to distribute the load across the cluster, ensuring optimal resource utilization and performance.”
