The Marketing department needs to recover files in a Nutanix Files share with a recovery window of 14 days.
Nutanix Files, part of Nutanix Unified Storage (NUS), supports file recovery through Self-Service Restore (SSR) for SMB shares, which relies on snapshots to provide previous versions of files.
Analysis of Options:
* Option A (Change default settings in the Protection Configuration window): Incorrect. The
"Protection Configuration window" is not a specific feature in Nutanix Files. This may be a vague reference to snapshot policies, but the correct terminology is Protection Domain or snapshot schedules, as in option B.
* Option B (Change the Protection Domain settings to keep at least 14 days of snapshots): Correct.
Nutanix Files uses snapshots to enable file recovery via SSR. These snapshots are managed through Protection Domains (or snapshot schedules in newer terminology) in Prism Element or Prism Central.
To ensure files can be restored within a 14-day timeframe, the snapshot retention policy must be configured to retain snapshots for at least 14 days.
* Option C (Install Nutanix Guest Tools on clients who need to perform Self-Service Restore):
Incorrect. Nutanix Guest Tools (NGT) is used for VM management features (e.g., VSS snapshots for backups, VM mobility), but it is not required for Self-Service Restore in Nutanix Files. SSR is a client- side feature for SMB shares that works natively with Windows clients (via the Previous Versions tab) and does not require NGT.
* Option D (Enable Self-Service Restore at the share level): Correct. Self-Service Restore (SSR) must be enabled at the share level in Nutanix Files to allow users to recover files without administrator intervention. This feature enables the Marketing department to restore files directly from their Windows clients using the Previous Versions feature, provided snapshots are available (as configured in option B).
Selected Configurations:
* B: Configuring the snapshot retention to at least 14 days ensures that previous versions of files are available for recovery within the required timeframe.
* D: Enabling SSR at the share level allows the Marketing department to perform the recovery themselves, meeting the requirement for user-driven file recovery.
Exact Extract from Nutanix Documentation:
From the Nutanix Files Administration Guide (available on the Nutanix Portal):
"Self-Service Restore (SSR) allows users to recover previous versions of files in SMB shares. To enable SSR, it must be activated at the share level in the Files Console. SSR relies on snapshots to provide previous versions; ensure that snapshot schedules (via Protection Domains or snapshot policies) are configured to retain snapshots for the desired recovery period, such as 14 days."

To scale out an existing Files instance, the administrator needs to add one Client IP and one Storage IP for each additional FSVM. Since the Files instance needs to expand from four FSVMs to six FSVMs, the administrator needs to add two Client IPs and two Storage IPs in total. The Client IPs are used for communication between the FSVMs and the clients, while the Storage IPs are used for communication between the FSVMs and the CVMs. References: Nutanix Files Administration Guide, page 28; Nutanix Files Solution Guide, page 7

Volumes is a feature that allows users to create and manage block storage devices (volume groups) on a Nutanix cluster. Volume groups can be accessed by external hosts using the iSCSI protocol. To ensure maximum performance, throughput, and redundancy for Oracle RAC on Linux implementation, while using the native method for securing workloads, the recommended configuration is to use Volumes with MPIO (Multipath I/O) and a single vDisk (virtual disk). MPIO is a technique that allows multiple paths between an iSCSI initiator and an iSCSI target, which improves performance and availability. A single vDisk is a logical unit number (LUN) that can be assigned to multiple hosts in a volume group, which simplifies management and reduces overhead.

The two steps that the administrator should perform to resolve the connectivity issues with the domain controller servers are:
Verify the DNS settings in Prism Element: DNS (Domain Name System) is a system that translates domain names into IP addresses. DNS settings are configurations that specify which DNS servers to use for resolving domain names. Verifying the DNS settings in Prism Element is a step that the administrator should perform, because it can help identify and correct any incorrect or outdated DNS server addresses or domain names that may cause connectivity issues with the domain controller servers.
Verify the DNS entries for the given domain name: DNS entries are records that map domain names to IP addresses or other information. Verifying the DNS entries for the given domain name is another step that the administrator should perform, because it can help check and update any incorrect or outdated IP addresses or other information that may cause connectivity issues with the domain controller servers.

The action that is required to allow the deletion of file server audit data in Data Lens is to update the data retention period. Data retention period is a setting that defines how long Data Lens keeps the file server audit data in its database. Data Lens collects and stores various metadata and statistics from file servers, such as file name, file type, file size, file owner, file operation, file access time, etc. Data Lens uses this data to generate reports and dashboards for file analytics and anomaly detection. The administrator can update the data retention period for each file server in Data Lens to control how long the audit data is kept before being deleted. References: Nutanix Files Administration Guide, page 98; Nutanix Data Lens User Guide Audit data in Data Lens is managed by a retention period, after which the data is automatically deleted. To allow deletion of audit data (e.g., to free up space or comply with policies), the administrator must update the retention period to a shorter duration, triggering the deletion of data that exceeds the new period. This is the standard method for managing audit data lifecycle in Data Lens.
Exact Extract from Nutanix Documentation:
From the Nutanix Data Lens Administration Guide (available on the Nutanix Portal):
"Audit data in Data Lens is retained for a configurable retention period. To allow the deletion of file server audit data, update the data retention period in the Data Lens console or Prism Central settings. Reducing the retention period will cause older audit data to be deleted once it exceeds the new period."
