NCP-US Questions and Answers

According to Nutanix Support & Insights1, Nutanix Volumes is a feature that provides block storage for both VMs and physical hosts using iSCSI protocol. A volume group (VG) is a collection of one or more disks in a Nutanix storage container.

According to Scale-Out Cloud Block Storage Built For AOS | Nutanix2, Flash Mode is an option that allows you to pin a VG to SSD tier for optimal performance. This can help improve the performance of a database server storage that is experiencing persistent slow queries.

 According to Nutanix documentation on unified storage (NCP-US) v6, to automatically delete backups older than one year, an administrator should modify the existing bucket lifecycle policy to set the expiration period to one year. Lifecycle policies enable administrators to automate the transition of objects to different storage classes and to expire them altogether. In this scenario, modifying the existing bucket lifecycle policy to shorten the expiration period to one year will ensure that backups older than one year are automatically deleted to free up space in the cluster.

• The administrator should avoid allocating over half the RAM on a host to a FSVM because the FSVM would cross NUMA node boundaries (option A).
• NUMA (Non-Uniform Memory Access) is a memory architecture that divides the system memory into multiple regions that are assigned to different processors or cores.
• If a FSVM crosses NUMA node boundaries, it will have to access memory from different regions, which will result in higher latency and lower performance for file operations.
• To avoid this issue, the administrator should ensure that the FSVM memory allocation is within a single NUMA node boundary.

Smart DR enables granular recovery of individual file shares in Nutanix Files by replicating data at the share level. This allows for more fine-grained control over the failover process and ensures that only critical data is recovered in the event of a disaster or outage.

 Files Smart DR is a feature that allows you to replicate between Files instances, either on-premises or running on Nutanix Cloud Clusters on AWS1. With Files Smart DR, you can configure granular share replication, which means you can select which shares to replicate and which ones to exclude1. Therefore, the correct answer to your question is B. Smart DR.

Files Smart DR also supports replicating snapshots between the source share and its target, which can help with data recovery and compliance2. Additionally, Files Smart DR is the mechanism by which Files will support disaster recovery in the Nutanix Xi cloud3.

This is because this bundle contains LCM file manager component that is required for LCM inventory to work in dark site mode.

• Download lcm_file_analytics_x.x.x.tar.gz bundle from Nutanix portal which contains File Analytics software binaries.
• Download lcm_file_manager_x.x.x.tar.gz bundle from Nutanix portal which contains LCM file manager component that handles file operations such as upload, download and delete.
• Transfer both bundles to a dark site web server that is accessible by LCM.
• Configure LCM settings in Prism Element to use dark site mode and specify the URL of the dark site web server.
• Perform LCM inventory which scans for available software bundles on the dark site web server.
• Upgrade File Analytics using LCM which downloads and installs File Analytics software binaries from lcm_file_analytics_x.x.x.tar.gz bundle.

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.
