NCP-US Online Practice Questions and Answers

Correct Answer: AB

Explanation: Nutanix Objects supports directory services integration, which allows administrators to configure access keys based on directory and email-based users. This enables granular access control and security for buckets and objects. The administrator can configure directory services under the Access Keys section in Prism Central, and then generate access keys for internal users from the directory service and for the consultant from an email address2.

Correct Answer: C

Explanation: The most likely cause for this issue is that the file server resides on a single node cluster. A distributed share is a type of SMB share or NFS export that distributes the hosting of top-level directories across multiple FSVMs, which improves load balancing and performance. A distributed share cannot be created on a single node cluster, because there is only one FSVM available. A distributed share requires at least two nodes in the cluster to distribute the directories. Therefore, the option to use distributed share/export type instead of standard is not present when creating a share on a single node cluster.

Correct Answer: B

Explanation: Nutanix Volumes allows administrators to provision a volume group with one or more volumes that can be attached to multiple VMs or physical servers via iSCSI. This enables the creation of a Microsoft Server Failover Cluster that uses shared storage for a critical application. The volume group can be attached to VMs running on an AHV-hosted cluster and bare metal servers for maximum resiliency1. References: Nutanix Volumes Administration Guide1

Correct Answer: B

Explanation: With the settings shown on the exhibit, if there were 1000 files in the repository, 10 files would have to be deleted within an hour to trigger an anomaly alert to the administrator. Anomaly alert is a feature that notifies the administrator when there is an unusual or suspicious activity on file data, such as mass deletion or encryption. Anomaly alert can be configured with various parameters, such as threshold percentage, time window, minimum number of files, and so on. In this case, the threshold percentage is set to 1%, which means that if more than 1% of files in a repository are deleted within an hour, an anomaly alert will be triggered. Since there are 1000 files in the repository, 1% of them is 10 files. Therefore, if 10 or more files are deleted within an hour, an anomaly alert will be sent to the administrator.

Correct Answer: B

Explanation: The Minerva_cvm.log file contains information about the Minerva service, which is responsible for managing the FSVMs and their communication with Prism Central. The Minerva_cvm.log file can be used to troubleshoot issues related to Nutanix Files, such as duplicate IP address detection. The log file can be found in /home/nutanix/data/logs/minerva on any CVM in the cluster. References: Nutanix Support Portal - Troubleshooting Nutanix Files

Correct Answer: B

Explanation: Smart DR is a feature that allows share-level replication between active file server instances for disaster recovery. To configure Smart DR, one of the prerequisites is to open TCP port 7575 for all External/Client IPs of FSVMs on the Source and Target cluster. This port is used for communication between the FSVMs and Prism Central. If this port is not open, Smart DR policies will not be visible in the Policies tab in Prism Central.

Correct Answer: D

Explanation: The primary criteria that should be considered for performance-sensitive application shares with sequential I/O is throughput. Throughput is a measure of how much data can be transferred or processed in a given time period.

Throughput is usually expressed in megabytes per second (MB/s) or gigabytes per second (GB/s). Sequential I/O is a type of I/O pattern where data is read or written in a sequential order, such as streaming media, backup, or archive applications. Sequential I/O typically requires high throughput to transfer large amounts of data quickly and efficiently.

Correct Answer: C

Explanation: The tool that can be used to report on a specific user's activity within a Files environment is Data Lens Audit Trails. Data Lens Audit Trails is a feature that provides detailed logs of all file operations performed by users on Files shares and exports, such as create, read, write, delete, rename, move, copy, etc. Data Lens Audit Trails can help administrators track and audit user actions and identify any unauthorized or malicious activities. The administrator can use Data Lens Audit Trails to filter and search for a specific user's activity based on various criteria, such as file name, file type, file size, file path, file share, file server, operation type, operation time, operation status, and so on.

Correct Answer: D

Explanation: A distributed share is a type of SMB share or NFS export that distributes the hosting of top-level directories across multiple FSVMs, which improves load balancing and performance. A distributed share cannot be created on a single-node cluster, because there is only one FSVM available. A distributed share requires at least two nodes in the cluster to distribute the directories. Therefore, the task of creating a distributed share on a single-node cluster will fail. References: Nutanix Files Administration Guide, page 33; Nutanix Files Solution Guide, page 8

Correct Answer: B

Explanation: 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
