Data Lens is a feature that provides insights into the data stored in Files, such as file types, sizes, owners, permissions, and access patterns. Data Lens allows administrators to create reports on various aspects of their data and schedule them to run automatically on a weekly basis. References: Nutanix Data Lens Administration Guide

The administrator can achieve this requirement by creating a bucket replication rule and setting the destination Objects instance. Bucket replication is a feature that allows administrators to replicate data from one bucket to another bucket on a different Objects instance for disaster recovery or data migration purposes. Bucket replication can be configured with various parameters, such as replication mode, replication frequency, replication status, etc. Bucket replication can also replicate all versions of objects, including delete markers, which are special versions that indicate that an object has been deleted. By creating a bucket replication rule and setting the destination Objects instance, the administrator can replicate data from one Objects instance to another asynchronously, including all delete markers and versions. References: Nutanix Objects User Guide, page 19; Nutanix Objects Solution Guide, page 9

Nutanix Objects, part of Nutanix Unified Storage (NUS), supports replication of buckets between Object Store instances for disaster recovery (DR). The organization has two Objects instances across two sites, managed by the same Prism Central, and needs to replicate a bucket’s data asynchronously, including delete marker versions, to the secondary site.

Analysis of Options:

Option A (With Object Browser, upload the data at the destination site): Incorrect. The Object Browser is a UI tool in Nutanix Objects for managing buckets and objects, but it is not designed for replication. Manually uploading data to the destination site does not satisfy the requirement for asynchronous replication, nor does it handle delete marker versions automatically.

Option B (Leverage the Objects Baseline Replication Tool from a Linux VM): Incorrect. The Objects Baseline Replication Tool is not a standard feature in Nutanix Objects documentation. While third-party tools or scripts might be used for manual replication, Nutanix provides a native solution for bucket replication, making this option unnecessary and incorrect for satisfying the requirement.

Option C (Use a Protection Domain to replicate the Objects Volume Group): Incorrect. Protection Domains are used in Nutanix for protecting VMs and Volume Groups (block storage) via replication, but they do not apply to Nutanix Objects. Objects uses bucket replication rules for DR, not Protection Domains.

Option D (Create a Bucket replication rule, set the destination Objects instance): Correct. Nutanix Objects supports bucket replication rules to replicate data between Object Store instances asynchronously. This feature allows the organization to replicate the bucket to the secondary site, including all versions (such as delete marker versions), as required. The replication rule can be configured in Prism Central, specifying the destination Object Store instance, and it supports asynchronous replication for DR purposes.

Why Option D?

Bucket replication in Nutanix Objects is the native mechanism for asynchronous replication between Object Store instances. It supports replicating all versions of objects, including delete marker versions (which indicate deleted objects in a versioned bucket), ensuring that the secondary site has a complete replica of the bucket for DR. Since both Object Store instances are managed by the same Prism Central, the administrator can easily create a replication rule to meet the requirement.

Exact Extract from Nutanix Documentation:

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

“Nutanix Objects supports asynchronous bucket replication for disaster recovery. To replicate a bucket to a secondary site, create a bucket replication rule in Prism Central, specifying the destination Object Store instance. The replication rule can be configured to include all versions, including delete marker versions, ensuring that the secondary site maintains a complete replica of the bucket for DR purposes.”

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. References: Nutanix Files Administration Guide, page 32; Nutanix Files Troubleshooting Guide

The administrator can achieve this request by deleting and recreating a new Objects store with the updated name. Objects is a feature that allows users to create and manage object storage clusters on a Nutanix cluster. Objects clusters can provide S3-compatible access to buckets and objects for various applications and users. Objects clusters can be created and configured in Prism Central. However, once an Objects cluster is created, its name cannot be changed or edited. Therefore, the only way to change the name of an Objects cluster is to delete the existing cluster and create a new cluster with the updated name. References: Nutanix Objects User Guide, page 9; Nutanix Objects Solution Guide, page 8

Nutanix Files, part of Nutanix Unified Storage (NUS), uses File Server Virtual Machines (FSVMs) to manage file services (e.g., SMB, NFS). Each FSVM runs on a node in the Nutanix cluster, and the number of connections per node impacts the resource requirements, particularly memory (RAM), for the FSVMs. The administrator needs to size the memory for a Files instance where each node will handle an average of 4,000 connections.

Sizing Guidelines:

Nutanix provides sizing guidelines for Files deployments based on the number of connections per FSVM (and thus per node, assuming one FSVM per node, which is the default configuration). The memory requirements scale with the number of connections to ensure performance and stability:

The minimum memory per FSVM is 12 GiB (as noted in Question 2), which supports up to 1,000 connections.

For higher connection counts, Nutanix recommends increasing the memory proportionally.

According to Nutanix documentation:

Up to 1,000 connections: 12 GiB RAM per FSVM.

1,000 to 2,000 connections: 24 GiB RAM per FSVM.

2,000 to 4,000 connections: 48 GiB RAM per FSVM.

4,000 to 8,000 connections: 96 GiB RAM per FSVM.

Since the question specifies 4,000 connections per node, and assuming one FSVM per node (standard deployment), the FSVM on each node needs to handle 4,000 connections. Based on the sizing guidelines:

4,000 connections fall into the 4,000 to 8,000 range, requiring 96 GiB RAM per FSVM.

Since each node hosts one FSVM, this translates to 96 GiB RAM per node dedicated to the FSVM.

Analysis of Options:

Option A (32 GiB RAM per node): Incorrect. 32 GiB RAM per node is sufficient for up to 2,000 connections (24 GiB for the FSVM, plus some overhead), but it is insufficient for 4,000 connections, which require 96 GiB.

Option B (40 GiB RAM per node): Incorrect. 40 GiB RAM per node is still too low for 4,000 connections, as it falls short of the 96 GiB recommended for this connection range.

Option C (96 GiB RAM per node): Correct. 96 GiB RAM per node aligns with Nutanix’s sizing guidelines for an FSVM handling 4,000 to 8,000 connections, ensuring the Files instance can manage the expected load efficiently.

Option D (128 GiB RAM per node): Incorrect. While 128 GiB RAM per node would work, it exceeds the recommended sizing for 4,000 connections. Nutanix recommends 96 GiB for up to 8,000 connections, and 128 GiB is typically reserved for even higher connection counts (e.g., >8,000) or additional workloads on the node. The question asks for the “proper” sizing, which is the minimum recommended for the given load, making 96 GiB the correct choice.

Why Option C?

For 4,000 connections per node, Nutanix recommends 96 GiB RAM per FSVM (one FSVM per node), which translates to 96 GiB RAM per node dedicated to the FSVM. This ensures the Files instance can handle the connection load without performance degradation, aligning with Nutanix’s sizing guidelines.

Exact Extract from Nutanix Documentation:

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

“For Nutanix Files deployments, memory sizing depends on the number of connections per FSVM. For 4,000 to 8,000 connections, allocate 96 GiB of RAM per FSVM. Assuming one FSVM per node, this translates to 96 GiB RAM per node dedicated to the FSVM to ensure optimal performance.”

Additional Notes:

The question assumes one FSVM per node, which is the default configuration for Nutanix Files unless otherwise specified. If multiple FSVMs were on a single node, the total RAM would need to be adjusted, but the question’s phrasing (“per node”) aligns with the standard one-FSVM-per-node deployment.

The 96 GiB RAM is for the FSVM itself; the node may require additional RAM for other workloads (e.g., CVM, VMs), but the question focuses on the Files instance’s memory sizing, making 96 GiB the correct answer.

There are two ways to manage Objects: PC (Prism Central) and API (Application Programming Interface). PC is a web-based user interface that allows administrators to create, configure, monitor, and manage Objects clusters, buckets, users, and policies. API is a set of S3-compatible REST APIs that allows applications and users to interact with Objects programmatically. API can be used to perform operations such as creating buckets, uploading objects, listing objects, downloading objects, deleting objects, and so on. References: Nutanix Objects User Guide; Nutanix Objects API Reference Guide

The most efficient way to generate a report listing the files matching those in the exhibit is to use Report Builder in File Analytics. Report Builder is a feature that allows administrators to create custom reports based on various filters and criteria, such as file name, file type, file size, file owner, file age, file access time, file modification time, file permission change time, and so on. Report Builder can also export the reports in CSV format for further analysis or sharing. References: Nutanix Files Administration Guide, page 97; Nutanix File Analytics User Guide

The appropriate configuration to verify to allow successful Objects cluster deployment to this ESXi cluster is to ensure that vCenter in PE cluster is registered using FQDN (Fully Qualified Domain Name) and that vCenter details in Objects UI are using FQDN. FQDN is a domain name that specifies the exact location of a host in the domain hierarchy. For example, esxi01.nutanix.com is an FQDN for an ESXi host. Using FQDN instead of IP addresses can avoid certificate validation errors when deploying Objects clusters to ESXi clusters. References: Nutanix Objects User Guide, page 9; Nutanix Objects Troubleshooting Guide, page 5
