NCP-US-6.5 Leak Questions

The Files feature that the administrator should enable to ensure the sessions will auto-reconnect in such events is Durable File Handles. Durable File Handles is a feature that allows SMB clients to reconnect to a file server after a temporary network disruption or a client sleep state without losing the handle to the open file. Durable File Handles can improve the user experience and reduce the risk of data loss or corruption. Durable File Handles can be enabled for each share in the Files Console. References: Nutanix Files Administration Guide, page 76; Nutanix Files Solution Guide, page 10

Nutanix Volumes, part of Nutanix Unified Storage (NUS), provides block storage services via iSCSI to external hosts, such as physical servers. The iSCSI traffic is managed by the Controller VMs (CVMs) in the Nutanix cluster, and a virtual IP address called the Data Services IP is used for iSCSI communication. To isolate iSCSI traffic on a dedicated network, the administrator must ensure that this traffic is routed over the isolated network.

Analysis of Options:

Option A (Create a new network interface on the CVMs via ncli): Incorrect. While it’s possible to create additional network interfaces on CVMs using the ncli command-line tool, this is not the recommended or standard method for isolating iSCSI traffic. The Data Services IP is the primary mechanism for managing iSCSI traffic, and it can be assigned to an isolated network without creating new interfaces on each CVM.

Option B (Configure the Data Services IP on an isolated network): Correct. The Data Services IP (also known as the iSCSI Data Services IP) is a cluster-wide virtual IP used for iSCSI traffic. By configuring the Data Services IP to use an IP address on the isolated network (e.g., a specific VLAN or subnet dedicated to iSCSI), the administrator ensures that all iSCSI traffic is routed over that network, meeting the requirement for isolation. This configuration is done in Prism Element under the cluster’s iSCSI settings.

Option C (Configure network segmentation for Volumes): Incorrect. Network segmentation in Nutanix typically refers to isolating traffic using VLANs or separate subnets, which is indirectly achieved by configuring the Data Services IP (option B). However, “network segmentation for Volumes” is not a specific feature or configuration step in Nutanix; the correct approach is to assign the Data Services IP to the isolated network, which inherently segments the traffic.

Option D (Create a Volumes network in Prism Central): Incorrect. Prism Central is used for centralized management of multiple clusters, but the configuration of iSCSI traffic (e.g., the Data Services IP) is performed at the cluster level in Prism Element, not Prism Central. There is no concept of a “Volumes network” in Prism Central for this purpose.

Why Option B?

The Data Services IP is the key configuration for iSCSI traffic in a Nutanix cluster. By assigning this IP to an isolated network (e.g., a dedicated VLAN or subnet), the administrator ensures that all iSCSI traffic is routed over that network, achieving the required isolation. This is a standard and recommended approach in Nutanix for isolating iSCSI traffic.

Exact Extract from Nutanix Documentation:

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

“To isolate iSCSI traffic on a dedicated network, configure the Data Services IP with an IP address on the isolated network. This ensures that all iSCSI traffic between external hosts and the Nutanix cluster is routed over the specified network, providing network isolation as required.”

Nutanix File Analytics, part of Nutanix Unified Storage (NUS), provides audit trails to track user activities within Nutanix Files shares. Audit trails include details such as who accessed a file, from where, and what actions were performed. The administrator needs to view the audit trails for 100 users, which requires filtering or grouping the audit data by relevant criteria.

Analysis of Options:

Option A (Share Name): Correct. Audit trails in File Analytics can be filtered by Share Name, allowing the administrator to view activities specific to a particular share. Since the 100 users are connected to multiple shares, filtering by Share Name helps narrow down the audit trails to the shares being accessed by these users, making it easier to analyze their activities.

Option B (Client IP): Correct. File Analytics audit trails include the Client IP address from which a user accesses a share (as noted in Question 14). Filtering by Client IP allows the administrator to track the activities of users based on their IP addresses, which can be useful if the 100 users are accessing shares from known IPs, helping to identify their read/write activities.

Option C (Directory): Incorrect. While audit trails track file and directory-level operations, “Directory” is not a standard filter option in File Analytics audit trails. The audit trails can show activities within directories, but the primary filtering options are more granular (e.g., by file) or higher-level (e.g., by share).

Option D (Folders): Incorrect. Similar to “Directory,” “Folders” is not a standard filter option in File Analytics audit trails. While folder-level activities are logged, the audit trails are typically filtered by Share Name, Client IP, or specific files, not by a generic “Folders” category.

Selected Options:

A: Filtering by Share Name allows the administrator to focus on the specific shares accessed by the 100 users.

B: Filtering by Client IP enables tracking user activities based on their IP addresses, which is useful for identifying the 100 users’ actions across multiple shares.

Exact Extract from Nutanix Documentation:

From the Nutanix File Analytics Administration Guide (available on the Nutanix Portal):

“File Analytics Audit Trails allow administrators to filter user activities by various criteria, including Share Name and Client IP. Filtering by Share Name enables viewing activities on a specific share, while filtering by Client IP helps track user actions based on their source IP address.”

Nutanix Data Lens, a service integrated with Nutanix Unified Storage (NUS), provides data governance and security features for Nutanix Files. One of its key features is Audit Trails, which tracks user activities and file operations. The audit trails include specific details that can be monitored and reported.

Analysis of Options:

Option A (User Emails): Incorrect. Data Lens Audit Trails track user activities, but they do not specifically log user emails as an audit trail metric. User identities (e.g., usernames) are logged, but email addresses are not a standard audit trail field.

Option B (Client IPs): Correct. Data Lens Audit Trails include the client IP addresses from which file operations are performed, allowing administrators to track the source of user actions (e.g., which IP accessed or modified a file).

Option C (Files): Correct. Data Lens Audit Trails track file-level operations, such as access, modifications, deletions, and permission changes, making “Files” a key audit trail metric.

Option D (Anomalies): Incorrect. While Data Lens does detect anomalies (e.g., ransomware activity, unusual file operations), anomalies are a separate feature, not an audit trail. Audit Trails focus on logging specific user and file activities, while anomalies are derived from analyzing those activities.

Selected Audit Trails:

B: Client IPs are logged in audit trails to identify the source of file operations.

C: Files are the primary entities tracked in audit trails, with details on operations performed on them.

Exact Extract from Nutanix Documentation:

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

“Data Lens Audit Trails provide detailed logging of file operations, including the files affected, the user performing the action, and the client IP address from which the operation was initiated. This allows administrators to monitor user activities and track access patterns.”
