NCP-US Nutanix Certified Professional – Unified Storage (NCP-US) v6 exam Question and Answers

According to the Nutanix Files Solution Guide1, all the FSVMs have the same basic configuration: four vCPU and 12 GB of RAM1. However, you can add more vCPU, RAM, and FSVMs to the cluster1.

Based on this information, the alert: File Server In Heterogeneous State indicates that the FSVMs do not match in their CPU or memory configuration1. This could affect the performance and availability of the file server

According to Nutanix Files SMB Share Default Permission1, a standard share is created with default permissions for three built-in groups: Administrators, Users, and Backup Operators. This may not be suitable for hosting user data that needs to be evenly distributed across users.

According to Nutanix Support & Insights2, a distributed share is a type of SMB share that allows you to distribute files across multiple file servers for better performance and scalability. This can help optimize the I/O performance within the current environment.

According to Nutanix File and NFS Mount Examples3, a quota policy is a way to limit the amount of space that a user or group can consume on a share. This can help enforce the 1 TB limit on the share and ensure that each user gets an equal amount of space.

After implementing a new subnet for all Nutanix services, it is necessary to rediscover the new target or reestablish file sessions. When Nutanix is configured with a new network subnet, all the services running on the Nutanix cluster need to communicate with each other over the new network. Rediscovering the new target or reestablishing file sessions allows Nutanix to start using the new IP addresses on the new subnet, ensuring that communication between the different Nutanix services is established.

According to Nutanix Support & Insights1, “If you change the IP address of a Controller VM, hypervisor or IPMI interface on any node in a cluster that has iSCSI or Files enabled, you must rediscover the new target or reestablish Files sessions.” This is because “the iSCSI and Files services use static IP addresses for communication.”

These rules ensure that VMs are distributed across different hosts in a cluster, so that if one host fails, the impact on the VMs and their data will be minimal1. Nutanix Files also supports DFS-N (Distributed File System - Namespaces), which allows multiple file servers hosting the same data to support a common folder and provide site affinity for users2.

According to Nutanix documentation on unified storage (NCP-US) v6, Lifecycle policies enable administrators to ensure that objects in a bucket expire after a certain period of time. You can set rules to automate the transition of objects to different storage classes or to expire them altogether. This feature helps to manage storage costs by reducing the need to manually manage data retention policies for individual objects in a bucket.

Lifecycle policies allow you to define rules for automatically deleting or archiving objects in a bucket after a certain period of time1. This feature can help you reduce storage costs and manage data retention.

The mspcli_cluster_list command lists all the existing service domains for the cluster, which can help identify if there is an issue with the Object Store Domain entries. The mspcli_status command can be used to get detailed status information on the specified service domain specified by the  parameter.

Object storage is a good fit for applications that require versioning, replication, and a write-once-read-many (WORM) access model. Since eCommerce sites often store a large amount of unstructured data such as images, videos, and other multimedia content, object storage can provide a scalable, cost-effective, and highly available solution.

Object storage is also a good fit for Kubernetes-based applications that use microservices architecture, as objects can be accessed from multiple pods at the same time, without the need for complex file system sharing. Additionally, object storage can be easily integrated with Kubernetes using operators or API calls.

On the other hand, while volumes and file storage solutions such as SMB and NFS can also store static content, they may not be the best fit for the given application requirements. Volumes are often limited in terms of scalability and replication, while file storage solutions may not provide the same level of versioning and WORM capabilities as object storage.

As a result, the best solution for the given application requirements is Object storage.

Note that the exact implementation and configuration of the object storage solution may vary based on factors such as performance, availability, and security requirements.

S3 stands for simple storage service and it is a widely used object storage protocol that allows you to store and retrieve any amount of data from anywhere on the web. SMBv2 stands for server message block version 2and it is a file sharing protocol that enables access to files on remote servers. Nutanix Unified Storage Objects supports both S3 and SMBv2 protocols for data access.
