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

Nutanix Files can automatically rebalance data across FSVMs to optimize performance and capacity utilization. You can also manually trigger a rebalance from the Files Console Dashboard tab by clicking on Apply Recommendation.https://next.nutanix.com/community-blog-154/nutanix-files-4-0-new-features-performance-improvements-40544

Connect with MPIO to the iSCSI Data Services IP. The iSCSI Data Services IP (DSIP) is a virtual IP address that provides load balancing and failover for iSCSI traffic across all CVMs in a cluster. The MPIO (Multi-Path I/O) option enables multiple paths for iSCSI traffic between Windows clients and Nutanix Volumes. The Cluster Virtual IP (CVIP) is used for management and communication between CVMs and should not be used for iSCSI traffic.

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.

 Nutanix volume groups are collections of vDisks that can be exposed to virtual machines or physical hosts using iSCSI protocol. Nutanix volume groups have a shared attribute that allows multiple VMs to access them concurrently.

In the step for attach the volume group to the RAC VMs, he must create it with an attribute of shared = true. This is because if the volume group is not created with shared = true, then only one VM can access it at a time, which would prevent Oracle RAC from working properly.

The Objects Storage Network (internal) is a virtual network that connects all CVMs in a cluster that hosts an object store. The Objects Storage Network (External) is a virtual network that connects external clients to an object store. The Objects Public Network (Internal) and (External) are not required for deploying Objects.

According to Nutanix Volumes - Recommendations And Best Practices1, “Multiple disks per Nutanix node may also improve an application’s performance. For performance-intensive environments, we recommend using between four and eight disks per CVM for a given workload.” Therefore, the administrator should use multiple vDisks in the Volume Group to distribute the SQL workload across more disks and nodes.

Protection snapshots are external snapshots that can be used to recover the file server cluster or individual files and folders1. They can be created through a protection domain schedule or via a user-initiated one-time snapshot of the protection domain1. By configuring protection snapshots on the share/export, the administrator can enable self-service restore for users to revert documents to previous versions2.

According to the Nutanix Unified Storage (NCP-US) v6 documentation, once WORM (Write-Once-Read-Many) has been enabled on an Objects bucket, versioning cannot be immediately enabled. Instead, the WORM configuration must be disabled and then re-enabled, this time with Enable Version and Enable WORM checked. Since the administrator did not select Enable Version during the initial configuration, this step is necessary in order to enable versioning.

You can disable WORM within 24 hours of enabling it on a bucket1. This will allow you to change the versioning settings on the bucket.
