NCP-US Online Practice Questions and Answers

Correct Answer: C

Explanation: 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.

Correct Answer: D

Explanation: The number of configurable snapshots that are supported for SSR in a file server is 200. SSR (Snapshot-based Replication) is a feature that allows administrators to replicate snapshots of shares or exports from one file server to another file server on a different cluster or site for disaster recovery purposes. SSR can be configured with various parameters, such as replication frequency, replication status, replication mode, etc. SSR supports up to 200 configurable snapshots per share or export in a file server.

Correct Answer: D

Explanation: Before upgrading Objects Manager, the administrator must upgrade AOS to the latest version. AOS is the core operating system that runs on each node in a Nutanix cluster and provides the foundation for Objects Manager and Objects service. Upgrading AOS will ensure compatibility and stability for Objects components. References: Nutanix Objects Administration Guide, Acropolis Operating System Upgrade Guide

Correct Answer: C

Explanation: Smart Tiering is a feature that allows Files to tier data across different storage tiers based on the file size and access frequency. Smart Tiering supports files with a minimum size of 64 KiB and a maximum size of 5 TiB2. References: Nutanix Files Administration Guide2

Correct Answer: C

Explanation: The most likely cause of this issue is that the file server has been cloned. Cloning a file server is not a supported operation and can cause various problems, such as Data Lens not being able to enable or disable for the cloned file server. To avoid this issue, the administrator should use the scale-out feature to add more FSVMs to an existing file server, or create a new file server from scratch.

Correct Answer: D

Explanation: The action that the administrator should take to resolve this issue is to verify Access Keys for the user. Access Keys are credentials that allow users to access Objects buckets using S3-compatible APIs or tools. Access Keys consist of an Access Key ID and a Secret Access Key, which are used to authenticate and authorize requests to Objects. If the user is unable to write data in the bucket using an Active Directory account, it may be because the user does not have valid Access Keys or the Access Keys do not have sufficient permissions. The administrator can verify and manage Access Keys for the user in Prism Central. References: Nutanix Objects User Guide, page 13; Nutanix Objects Solution Guide, page 8

Correct Answer: C

Explanation: Volumes is a feature that allows users to create and manage block storage devices (volume groups) on a Nutanix cluster. Volume groups can be accessed by external hosts using the iSCSI protocol. To ensure maximum performance, throughput, and redundancy for Oracle RAC on Linux implementation, while using the native method for securing workloads, the recommended configuration is to use Volumes with MPIO (Multipath I/O) and a single vDisk (virtual disk). MPIO is a technique that allows multiple paths between an iSCSI initiator and an iSCSI target, which improves performance and availability. A single vDisk is a logical unit number (LUN) that can be assigned to multiple hosts in a volume group, which simplifies management and reduces overhead.

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: C

Explanation: One of the possible causes of a failed pre-upgrade check for Files is network connectivity issues between the FSVMs. The administrator should verify that there are no firewall rules or network policies that block the communication between the FSVMs on ports 22 (SSH), 9440 (HTTPS), and 2009 (RPC). The administrator can use tools such as ping, traceroute, and telnet to test the connectivity between the FSVMs. References: Nutanix Support Portal Troubleshooting Nutanix Files Upgrade Issues
