Pass the Nutanix Certified Professional - Unified Storage (NCP-US) v6.10 NCP-US-6.10 Questions and answers with ValidTests

The exhibit shows the output of the `get-smbclient configuration` command on a Nutanix Files system, with the line `RequireSecuritySignature: True` highlighted as a potential cause for the administrator’s inability to browse an SMB share. The setting `RequireSecuritySignature: True` indicates that the SMB client requires security signatures (also known as SMB signing) for all SMB communications, which ensures data integrity and authenticity. A possible cause of the browsing issue related to this setting is that **Kerberos is enabled**, as Kerberos authentication is often required when SMB signing is enforced, especially in Active Directory (AD) environments.

The **Nutanix Unified Storage Administration (NUSA)** course explains that “in Nutanix Files, when `RequireSecuritySignature` is set to True, SMB signing is mandatory, and this often relies on Kerberos authentication to provide the necessary security tokens for signing SMB packets.” Kerberos is the default authentication protocol in AD environments, and Nutanix Files integrates with AD for SMB share access. If the client attempting to browse the share does not support Kerberos or has issues with Kerberos authentication (e.g., misconfigured AD, time sync issues, or lack of domain credentials), the SMB connection may fail, resulting in the inability to browse the share.

The **Nutanix Certified Professional - Unified Storage (NCP-US)** study guide further elaborates that “enabling `RequireSecuritySignature` in Nutanix Files often requires Kerberos authentication to be properly configured, as SMB signing uses Kerberos tickets to secure communication, and mismatches in Kerberos settings can prevent share access.” The administrator should verify that the client is domain-joined, Kerberos is functioning correctly (e.g., by checking time sync between the client, Nutanix Files, and the AD domain controller), and that the necessary Kerberos tickets are available.

The other options are incorrect:

- **AD is enabled**: While AD is typically enabled in environments where SMB signing and Kerberos are used, simply enabling AD does not directly cause the issue. The problem is more specifically tied to Kerberos, which is the authentication mechanism AD uses.

- **TLS is enabled**: TLS (Transport Layer Security) is not directly related to SMB signing. SMB signing operates at the SMB protocol level, while TLS would apply to network-layer encryption, which is not indicated in the configuration output.

- **CHAP is enabled**: CHAP (Challenge-Handshake Authentication Protocol) is used for protocols like iSCSI or PPP, not SMB, and is irrelevant to this issue.

The NUSA course documentation emphasizes that “if `RequireSecuritySignature` is enabled and users cannot browse SMB shares, administrators should check Kerberos authentication settings, as mismatches or failures in Kerberos can prevent successful SMB connections.”

After enabling Nutanix Objects in a Nutanix cluster, the next action before starting the deployment is tocreate an Object Store. Enabling Nutanix Objects activates the object storage service on the cluster, but the actual deployment involves creating an object store instance, which defines the storage resources, network settings, and other configurations needed for object storage operations.

TheNutanix Unified Storage Administration (NUSA)course states, “After enabling Nutanix Objects, the administrator must create an Object Store to deploy the object storage service, specifying parameters such as storage capacity, network settings, and domain name.” The object store is the primary entity in Nutanix Objects, and creating it sets up the infrastructure for buckets, S3-compatible APIs, and other object storage features. Only after the object store is created can buckets be added and used for storing objects.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further elaborates that “the deployment of Nutanix Objects begins with creating an Object Store, which initializes the service and prepares it for bucket creation and data storage.” This step is necessary to operationalize Nutanix Objects after enabling the feature in the cluster.

The other options are incorrect:

Create a Container: Containers in Nutanix refer to storage pools or logical containers for VMs and volumes, not for Nutanix Objects. In the context of Objects, the equivalent is a bucket, which is created after the object store.

Perform an LCM inventory: An LCM inventory is relevant for upgrades, not for the initial deployment of Nutanix Objects after enabling the feature.

Create a Volume Group: Volume groups are used for Nutanix Volumes (block storage), not Nutanix Objects (object storage).

The NUSA course documentation emphasizes that “creating an Object Store is the first step after enabling Nutanix Objects, ensuring the service is deployed and ready for use.”

To receive email notifications about unusual behavior related to permission changes on corporate file shares, the administrator shoulddefine anomaly rulesin Nutanix File Analytics. File Analytics is a monitoring and analytics tool for Nutanix Files that provides visibility into file share activities, including permission changes, access patterns, and potential security threats. Anomaly rules allow administrators to detect and be notified of unusual or suspicious activities, such as unexpected permission modifications.

TheNutanix Unified Storage Administration (NUSA)course explains that File Analytics includes an anomaly detection feature that uses machine learning to identify deviations from normal behavior. The course states, “Administrators can define anomaly rules in File Analytics to monitor specific activities, such as permission changes, and configure email notifications for timely alerts.” By setting up anomaly rules, the administrator can specify criteria for permission-related events and enable email alerts to be sent when such anomalies are detected.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further elaborates that “File Analytics anomaly rules can be customized to track permission changes, excessive file access, or other suspicious activities, with notifications sent via email to ensure timely response.” This makes anomaly rules the most appropriate method for addressing the administrator’s requirement.

The other options are not suitable:

Create an Alert Policy: Alert policies in Nutanix are typically used for system-level events (e.g., hardware failures or cluster issues) managed through Prism Central, not for file share-specific activities like permission changes.

Configure Events Quotas: Events quotas are used to manage resource limits or thresholds, not to monitor or notify about specific activities like permission changes.

Set Ransomware Email Recipient: This option is specific to ransomware detection in File Analytics, which focuses on identifying file encryption or mass file modifications, not permission changes.

The NUSA course documentation notes that “File Analytics anomaly rules provide granular control over monitoring file share activities, with email notifications ensuring administrators are promptly informed of potential security issues like unauthorized permission changes.”

The issue involves an administrator attempting to upgrade a Nutanix Objects cluster using Prism Central’s Lifecycle Manager (LCM), but the latest version of Nutanix Objects is not listed after running an inventory, despite other components (MSP Controller, Objects Manager, Objects Services) being updated. The most likely reason is thatPrism Central is not running a compatible versionrequired to support the latest Nutanix Objects version.

TheNutanix Unified Storage Administration (NUSA)course states, “LCM upgrades for Nutanix Objects require Prism Central to be running a version that is compatible with the target Objects version; if Prism Central is not on a compatible version, the latest Objects version will not be listed in the LCM inventory.” Prism Central orchestrates LCM upgrades, and its version must support the new features, APIs, and metadata of the target Nutanix Objects version. If Prism Central is running an older version, it may not recognize or list newer versions of Nutanix Objects available for upgrade.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further elaborates that “a common reason for missing component versions in LCM is an incompatible Prism Central version; administrators must ensure Prism Central is upgraded to a version that supports the target Nutanix Objects release.” The guide recommends checking the Nutanix compatibility matrix to verify that the current Prism Central version supports the desired Objects version and upgrading Prism Central if necessary.

The other options are incorrect:

The administrator does not have needed permissions: The administrator has already logged into Prism Central, navigated to the LCM page, and performed an inventory, indicating sufficient permissions to view available versions. Permission issues would typically prevent access to LCM entirely.

The Objects version is not supported on-premise: Nutanix Objects is fully supported on-premise, and there is no indication that the target version is cloud-only.

The MSP Controller on Prism Element has not been updated: The MSP Controller has already been updated to the latest version as per the scenario, and the MSP Controller on Prism Element is not directly responsible for listing Objects versions in Prism Central’s LCM.

The NUSA course documentation emphasizes that “ensuring Prism Central is on a compatible version is a critical step before upgrading Nutanix Objects via LCM; an incompatible Prism Central version will prevent the latest Objects version from appearing in the inventory.”

Nutanix Files Smart Tiering offers two modes:

Standard Tiering: Tiers data to internal Nutanix Objects (on the same cluster).

Advanced Tiering: Tiers data to external S3-compatible storage (on-premises or public cloud).

The requirement specifies an *on-premise S3 bucket* with no cloud services, making Advanced Tiering the solution.

Option A (Standard): Requires internal Nutanix Objects, not external S3.

Option C (Files Analytics): Provides usage insights but doesn’t tier data.

Option D (Data Lens): A cloud-based governance tool (requires cloud connectivity).

To monitor key information about a Nutanix Files deployment, such asMalicious Clients,Vulnerable Shares, and alist of potential ransomware attack attempts, the administrator must deploy theFile Analytics VMon-premises. Nutanix File Analytics is a dedicated virtual machine that provides advanced monitoring and analytics for Nutanix Files, offering insights into security-related activities, including malicious client behavior, share vulnerabilities, and ransomware detection.

TheNutanix Unified Storage Administration (NUSA)course states, “File Analytics is a VM that must be deployed on-premises to provide detailed monitoring of Nutanix Files, including identifying Malicious Clients, Vulnerable Shares, and potential ransomware attack attempts through its analytics and anomaly detection features.” File Analytics includes dashboards and widgets that specifically highlight security risks, such as the Malicious Clients list (clients exhibiting suspicious behavior), Vulnerable Shares (shares with overly permissive access), and ransomware detection (based on file activity patterns like mass encryption or renaming).

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further elaborates that “deploying the File Analytics VM enables administrators to monitor Nutanix Files for security threats, providing visibility into Malicious Clients, Vulnerable Shares, and ransomware attempts through its integrated analytics engine.” File Analytics runs locally within the Nutanix cluster, making it suitable for on-premises deployments and capable of operating in isolated environments like dark sites.

The other options are incorrect:

LCM dark site webserver: An LCM dark site webserver is used to host software updates for LCM in air-gapped environments but does not provide monitoring or analytics for Nutanix Files.

Prism Central: Prism Central provides centralized management and monitoring for Nutanix clusters but does not offer the specific security-focused analytics (e.g., Malicious Clients, ransomware detection) that File Analytics provides for Nutanix Files.

Data Lens: Nutanix Data Lens is a cloud-based service for data lifecycle management and analytics, primarily for Nutanix Objects and Files, but it focuses on tiering and data placement, not security monitoring like ransomware detection or malicious clients.

The NUSA course documentation emphasizes that “the File Analytics VM is the essential on-premises component for monitoring Nutanix Files, providing critical security insights such as Malicious Clients, Vulnerable Shares, and ransomware attack attempts.”

The administrator is attempting to scale out a Nutanix Files deployment by adding more File Server Virtual Machines (FSVMs) to a multi-node FSVM deployment on a three-node AHV cluster, but the operation has failed. The first step the administrator should take is toexpand the AHV cluster. Nutanix Files requires a minimum number of nodes in the cluster to support a scale-out operation, and a three-node cluster may not have sufficient resources (nodes) to accommodate additional FSVMs.

TheNutanix Unified Storage Administration (NUSA)course states, “Nutanix Files scale-out operations require sufficient cluster nodes to host additional FSVMs, and a minimum of four nodes is recommended for scaling out a multi-node FSVM deployment.” In a three-node cluster, each node typically hosts one FSVM (for a total of three FSVMs), and scaling out to add more FSVMs requires additional nodes to distribute the new FSVMs. If the cluster does not have enough nodes, the scale-out operation will fail, as there are no available nodes to host the new FSVMs.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further elaborates that “when a Nutanix Files scale-out operation fails on a small cluster, the first step is to verify the cluster size and expand the AHV cluster by adding more nodes to support the additional FSVMs.” Expanding the cluster to at least four nodes provides the necessary capacity to host a new FSVM, allowing the scale-out operation to succeed.

The other options are incorrect:

Add RAM to the physical hosts: While insufficient RAM could cause issues, the failure of a scale-out operation is more likely due to a lack of nodes rather than RAM, especially since FSVMs have specific node placement requirements.

Failover to secondary site: Failover to a secondary site is relevant for disaster recovery (e.g., using Smart DR), not for resolving a scale-out failure within the primary cluster.

Add DNS entries: DNS entries may be needed for client access to Nutanix Files, but they are not directly related to the scale-out operation of FSVMs within the cluster.

The NUSA course documentation emphasizes that “a common cause of Nutanix Files scale-out failures in small clusters is insufficient nodes; expanding the AHV cluster to at least four nodes is the first step to ensure successful scaling.”

In Nutanix Unified Storage (specifically when using Volume Groups as iSCSI targets for VMs),IO performance scalingand redundancy acrossmultiple CVMsdepends on theiSCSI MPIO (Multi-Path I/O)feature configured within theguest OS.

According to the NUSA course:

“To leverage multiple CVMs for servicing IO requests to a volume group, MPIO must be configured in the guest operating system. MPIO allows the VM to establish multiple concurrent iSCSI sessions to the Nutanix cluster, balancing the load across available CVMs.”

Without MPIO, even if multiple CVMs host the VG target, the guest OS will typically establish asingle iSCSI sessionto one CVM at a time, limiting scalability and redundancy.

The virtual RAID controller in the guest OS (option A) has no impact on how iSCSI paths are handled at the network level.

Flash mode (option C) only affects local performance caching and does not provide multi-path IO.

Configuring multiple vDisks in a VG (option D) improves storage organization but does not automatically enable multi-path IO to different CVMs.

Thus, the administrator mustenable iSCSI MPIO in the guest OSto ensure the VM can leverage multiple CVMs for IO operations.

Nutanix File Analytics sends anomaly alerts and data to email recipientsas defined in the Anomaly Rules. File Analytics uses anomaly detection to identify unusual activities on the file server, such as permission changes, excessive file access, or potential ransomware behavior. Administrators can configure anomaly rules to specify which activities to monitor and how to handle notifications, including sending emails to designated recipients based on the defined rules.

TheNutanix Unified Storage Administration (NUSA)course explains that “File Analytics allows administrators to define anomaly rules to detect suspicious activities, with email notifications configured as part of the rule settings to alert recipients when specific conditions are met.” This ensures that emails are sent only when the criteria in the anomaly rules are triggered, allowing for targeted and timely alerts.

TheNutanix Certified Professional - Unified Storage (NCP-US)study guide further states that “anomaly rules in File Analytics are customizable, enabling administrators to set thresholds, conditions, and notification preferences, including email alerts, to ensure timely responses to detected anomalies.” The timing and frequency of email notifications depend on the configuration of the anomaly rules, not a fixed schedule or automatic detection.

The other options are incorrect:

Whenever an anomaly is detected: While anomalies trigger alerts, emails are sent only if the anomaly rules are configured to do so. Not every detected anomaly automatically results in an email unless specified in the rules.

Every 15 minutes: File Analytics does not send emails on a fixed 15-minute schedule; notifications are event-driven based on anomaly rule triggers.

When a minimum of anomalies are detected: There is no concept of a “minimum number of anomalies” in File Analytics; alerts are sent based on the specific conditions defined in the anomaly rules.

The NUSA course documentation emphasizes that “File Analytics anomaly rules provide granular control over alert notifications, with email alerts sent to recipients as specified in the rule configuration, ensuring timely communication of critical events.”

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.
