Free Practice Questions for Nutanix NCP-US-6.10 Exam

To meet the requirement of acommon namespacefor two Nutanix Objects instances located in New York and London, managed by separate Prism Central instances with availability zone pairing and IAM replication, the administrator shouldcreate a Global Namespace. A global namespace in Nutanix Objects allows multiple object store instances to share a unified namespace, enabling consistent access to buckets and objects across geographically distributed sites using a single naming convention.

TheNutanix Unified Storage Administration (NUSA)course explains that “Nutanix Objects supports a global namespace to provide a unified view of buckets across multiple object store instances, which is critical for distributed environments requiring consistent data access.” This feature ensures that applications and users can access objects using the same bucket names and paths, regardless of the physical location of the object store (e.g., New York or London). The global namespace is particularly useful in scenarios involving availability zone pairing, where data consistency and accessibility across regions are required.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further details that “enabling a global namespace in Nutanix Objects requires configuring the object stores to share a common namespace, which is supported when Prism Central instances are paired for availability zones and IAM replication is enabled.” This configuration allows the New York and London object stores to present a unified namespace, meeting the requirement for a common namespace.

The other options are incorrect:

Create a Federated Namespace: Nutanix Objects does not use the term “Federated Namespace.” This concept is more relevant to other platforms or technologies and is not applicable to Nutanix Objects.

Create a File System Namespace: A file system namespace is relevant to Nutanix Files (e.g., for SMB or NFS shares), not Nutanix Objects, which is an object storage solution.

Create a Kubernetes Namespace: A Kubernetes namespace is used to organize resources in a Kubernetes cluster and is unrelated to Nutanix Objects or its namespace requirements.

The NUSA course documentation notes that “a global namespace in Nutanix Objects is configured through Prism Central, leveraging availability zone pairing and IAM replication to ensure consistent bucket naming and access across distributed object stores.” The administrator should configure the global namespace in the Nutanix Objects settings for both the New York and London instances, ensuring that the Prism Central instances are properly paired and IAM replication is active.

To determine if the Nutanix File Server is being used to store personal photos and videos, the administrator shouldexamine the File Distribution by Type widget in the File Analytics dashboard for the File Server. Nutanix File Analytics is a monitoring and analytics tool that provides detailed insights into file share activities, including the types of files stored on the file server. The File Distribution by Type widget specifically categorizes files by their extensions (e.g., .jpg, .mp4), allowing the administrator to identify whether image or video files are present.

TheNutanix Unified Storage Administration (NUSA)course states, “The File Analytics dashboard includes the File Distribution by Type widget, which displays the breakdown of file types stored on the Nutanix File Server, enabling administrators to identify specific file categories such as images or videos.” This widget provides a visual representation of file types, making it easy to detect if personal photos (e.g., .jpg, .png) or videos (e.g., .mp4, .avi) are being stored.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further elaborates that “File Analytics offers granular visibility into file storage patterns through widgets like File Distribution by Type, which is ideal for identifying unauthorized or non-business-related content, such as personal media files.” By accessing this widget in the File Analytics dashboard, the administrator can confirm the presence of photo and video files and take appropriate action, such as setting policies to restrict such content.

The other options are incorrect or insufficient:

Examine the Usage Summary table for the File Server Container in the Prism Element Storage page: The Usage Summary table in Prism Element provides high-level storage metrics (e.g., capacity usage) but does not break down data by file type, so it cannot identify photos or videos.

Examine the File Activity widget in the File Analytics dashboard for the File Server: The File Activity widget shows file access patterns (e.g., read/write operations) but does not provide details about file types, making it unsuitable for this purpose.

Examine the File Distribution by Type widget from the Files Console for the File Server: The Nutanix Files Console is used for managing file servers and shares, but it does not include a File Distribution by Type widget. This widget is specific to the File Analytics dashboard.

The NUSA course documentation highlights that “the File Distribution by Type widget in File Analytics is a key tool for auditing file content, allowing administrators to detect and manage non-compliant or personal files, such as photos and videos, stored on the file server.”

The workload type that describes I/O sizes for read and write operations that areless than or equal to 16 KBwhile file sizes are10 MB or moreisRandom. In Nutanix Files, workload types are used to optimize share performance based on I/O patterns. Small I/O sizes (≤16 KB) indicate a random access pattern, as opposed to sequential, even if the files themselves are large (≥10 MB). This is common in workloads like databases or virtual desktops, where small, non-contiguous I/O operations are performed on larger files.

TheNutanix Unified Storage Administration (NUSA)course states, “A Random workload type in Nutanix Files is characterized by small I/O sizes, typically 16 KB or less, regardless of file size, as it reflects random access patterns rather than sequential ones.” The Random workload type optimizes the share for such patterns by adjusting caching, prefetching, and data placement to handle frequent small I/O operations efficiently, even when the files are large.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further elaborates that “workloads with I/O sizes of 16 KB or less, even on large files (e.g., 10 MB or more), are classified as Random, as the small I/O size indicates non-sequential access patterns.” Large file sizes do not necessarily imply sequential I/O; the I/O size itself determines the workload type, and 16 KB or less is typical of random access.

The other options are incorrect:

Sequential: Sequential workloads involve larger I/O sizes (typically >64 KB) and contiguous access patterns, such as those seen in media streaming or backups, not small I/O sizes like 16 KB or less.

Asynchronous: Asynchronous is not a workload type in Nutanix Files; it may refer to replication or I/O handling methods but is not relevant here.

Default: The Default workload type applies a balanced configuration but does not specifically optimize for small I/O sizes like the Random type does.

The NUSA course documentation emphasizes that “I/O sizes of 16 KB or less, even with large file sizes, indicate a Random workload type in Nutanix Files, ensuring optimal performance for random access patterns.”

According to the Nutanix Unified Storage Administration (NUSA) course, specifically in the module “Deploying and Configuring Nutanix Objects,” theObject Store creationprocess within Prism Central depends on theregistration and access synchronizationbetween Prism Central and Prism Element. The documentation explicitly states:

“When Prism Central is first connected to a Prism Element cluster, there may be a delay of up to 15 minutes for the access control and cluster data to fully synchronize. During this time, certain cluster resources may not appear when attempting to create new object stores.”

This statement confirms that if the access was granted to Prism Elementless than 5 minutes ago, the cluster will not yet be visible in the “Cluster” drop-down list. This delay in synchronization is the reason for the empty cluster list in the interface.

Option Ais incorrect because Prism Central administrators, not just local Prism Element admins, have the authority to create object stores.

Option Bis incorrect because the delay is not tied to the 1-hour registration time, but rather the few minutes required for initial synchronization.

Option Cis incorrect because the Prism Element admin role is not a prerequisite for this task within Prism Central.

To protect a Nutanix Objects store from a single node or two-drive failure, the cluster must be comprised of aminimum of seven nodes. Nutanix Objects uses erasure coding to provide resiliency, distributing data and parity fragments across nodes to ensure fault tolerance. To withstand a single node failure or a two-drive failure, a specific number of nodes is required to maintain data availability and rebuild capability.

TheNutanix Unified Storage Administration (NUSA)course states, “Nutanix Objects requires a minimum of seven nodes to ensure resiliency against a single node failure or a two-drive failure, using erasure coding to distribute data and parity across the cluster.” This configuration typically uses an erasure coding scheme like 4+2 or 5+2 (data + parity fragments), which requires at least six nodes for data distribution and an additional node to handle failures, totaling seven nodes.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further elaborates that “to achieve resiliency against a single node or two-drive failure in Nutanix Objects, the cluster must have at least seven nodes to support the erasure coding configuration needed for this level of fault tolerance.” This ensures that even if one node fails or two drives are lost, the remaining nodes have sufficient data and parity fragments to reconstruct the lost data.

The other options are incorrect:

Multi-cluster option must be disabled for the object store: The multi-cluster option is not relevant to resiliency within a single Nutanix Objects deployment. It pertains to managing multiple clusters, not erasure coding or fault tolerance.

Each node in the dense node platform requires 20 or more HDDs: There is no requirement for 20 or more HDDs per node to achieve this level of resiliency. Resiliency depends on the number of nodes and erasure coding, not the number of drives per node.

New storage container is created for the object store: While Nutanix Objects uses storage containers, creating a new container is not a requirement for enabling resiliency. Resiliency is determined by the cluster configuration and erasure coding settings.

The NUSA course documentation highlights that “a minimum of seven nodes ensures Nutanix Objects can maintain data availability and rebuild data in the event of a single node or two-drive failure, leveraging erasure coding for resiliency.”

Data Lens classifies files primarily by file extensions (e.g., .pdf, .xlsx) to:

Group files into categories (Documents, Media, Code, etc.).

Track storage usage/access patterns by type.

Other options are invalid:

A/B/D: File size, access time, and ownership are attributes but not classification criteria. Data Lens uses extensions as the default classifier.

When deploying Nutanix Files, the storage network requires **one additional IP address than the number of File Server Virtual Machines (FSVMs)**. Nutanix Files is a scale-out file storage solution that uses a distributed architecture, where each FSVM handles file services and communicates with clients and the Nutanix cluster. The IP address requirements include one IP address for each FSVM plus an additional virtual IP address (VIP) that serves as the client-facing endpoint for the file server.

The **Nutanix Unified Storage Administration (NUSA)** course explains that Nutanix Files deployment involves configuring a file server with a minimum of three FSVMs for high availability and scalability. Each FSVM requires a unique IP address on the storage network to handle internal communication and data operations. Additionally, a single VIP is configured for the file server to provide a unified access point for clients using protocols like SMB or NFS. This VIP is load-balanced across the FSVMs, ensuring seamless failover and scalability.

The **Nutanix Certified Professional - Unified Storage (NCP-US)** study guide specifies that “the storage network for Nutanix Files requires one IP address per FSVM plus one additional IP address for the file server VIP.” For example, a Nutanix Files deployment with three FSVMs would require four IP addresses: three for the FSVMs and one for the VIP. This configuration ensures that clients can access the file server through a single IP address, while the FSVMs handle the backend storage operations.

The other options are incorrect:

- **Same number of IP addresses as the number of FSVMs**: This does not account for the additional VIP required for client access, which is a critical component of the Nutanix Files architecture.

- **One less IP address than the number of FSVMs**: This is not feasible, as each FSVM requires its own IP address, and the VIP adds an additional requirement.

- **Twice as many IP addresses as the number of FSVMs**: This overestimates the IP address needs, as only one additional VIP is needed, not double the number of FSVMs.

The NUSA course documentation further clarifies that “the VIP is used to abstract the file server from the individual FSVMs, providing a single point of access for clients and enabling features like load balancing and failover.” The storage network must be configured with sufficient IP addresses to accommodate both the FSVMs and the VIP during deployment.

The Nutanix Unified Storage Administration (NUSA) course module “Configuring and Securing Volume Groups” specifies that to secure access to volume groups (VGs) containing sensitive data:

CHAP Authentication(Challenge-Handshake Authentication Protocol) provides an additional layer of security by requiring authentication before iSCSI connections are established. This satisfies the second requirement: “The access needs to be secured with an additional security login.”

IQN-based Access Controlensures that only the intended initiator (the client OS) can access the VG by explicitly specifying the IQN of the client in the VG configuration. This meets the first requirement: “The VG must be accessible only by the OS where the data is going to be used by the application.”

WhileOn-the-wire encryptionis beneficial for data confidentiality, the course emphasizes that CHAP and IQN-based controls are the specific mechanisms for access security.RDMA-capable NICsare not relevant to restricting access or security in this context.

Thewitness sharein a Windows Failover Cluster environment (for cluster quorum) requires a highly available and consistent SMB share.

In the NUSA course, it’s highlighted thatDistributed File System (DFS)is not compatible with witness share deployments because:

“When DFS is enabled on a Nutanix Files share, it redirects and abstracts file paths across multiple servers for redundancy and load balancing. However, Windows Failover Clustering requires direct access to a highly available SMB share without DFS interference to maintain strict cluster quorum consistency.”

Therefore, to deploy awitness share:

DFS must be disabled on the shareused for the cluster witness.

Enabling DFS causes redirection and breaks direct share connections that Failover Clustering needs.

WORM and share type are irrelevant here—DFS is the critical factor.

NFS is not suitable because Windows Failover Clustering requires SMB for witness shares.

Thus, to resolve the deployment issue, the administrator shoulddisable DFS on the shareintended for the witness role.
