NS0-162 Exam Dumps - NetApp Certified Data Administrator (ONTAP)

 You can use either XCP or the in-place conversion feature to move data from a FlexVol volume to a FlexGroup volume. XCP is a data migration tool that can copy data between different types of volumes, such as FlexVol and FlexGroup. The in-place conversion feature, introduced in ONTAP 9.7, allows you to convert a FlexVol volume to a FlexGroup volume without requiring a data copy or additional disk space. However, you cannot convert a FlexGroup volume back to a FlexVol volume. SnapMirror is not a valid option for this scenario, because it does not support replicating data from FlexVol to FlexGroup volumes. A FlexVol to FlexGroup conversion is supported, but only for transitioned volumes starting from ONTAP 9.8. References :- Converting FlexVol volumes to FlexGroup volumes overview, Can a FlexGroup be converted to a FlexVol?, Can I convert a Flexvol to FlexGroup without rewarming the tiered data?

 The error message in the exhibit indicates that access to a specific file was denied. This is typically due to insufficient permissions. By setting the user’s permission for the share to write, it would allow them to save files on that share. References: Troubleshooting CIFS or SMB access denied, Shared folder “Access is Denied” between Windows computers

Encrypted volumes are one of the possible causes of ONTAP upgrade pre-check failure. If the cluster has encrypted volumes, the pre-check verifies that the cluster has a valid external key manager (EKM) configuration and that the EKM server is reachable. If the EKM configuration is invalid or the EKM server is unreachable, the pre-check fails and the upgrade cannot proceed. To resolve this issue, the cluster administrator must ensure that the EKM configuration is correct and that the EKM server is accessible before retrying the upgrade12. References:- Execute ONTAP automated pre-upgrade checks before a planned upgrade, ONTAP upgrade pre-check validation fails with Error: The following nodes are not supported

To protect the data on your ONTAP C190 cluster using the native SnapMirror technology, you need to have two products that support SnapMirror replication and can run ONTAP software. The following two products would satisfy this request:

• ONTAP Select: This is a software-defined storage solution that runs on VMware ESXi hosts and can create and manage ONTAP clusters and nodes on the virtualized hardware. ONTAP Select supports SnapMirror replication for data protection and disaster recovery between ONTAP Select clusters or between ONTAP Select and other ONTAP systems12.
• Cloud Volumes ONTAP: This is a software-only storage service that runs on public cloud platforms such as AWS, Azure, and Google Cloud and provides enterprise-grade data management features such as SnapMirror replication. Cloud Volumes ONTAP supports SnapMirror replication for data protection and disaster recovery between Cloud Volumes ONTAP instances or between Cloud Volumes ONTAP and other ONTAP systems34.
• Cloud Volumes Service for AWS and Azure NetApp Files are not the products that can satisfy this request, as they are fully managed cloud storage services that do not run ONTAP softwareand do not support SnapMirror replication. They provide native cloud replication features such as AWS Backup and Azure Backup, which are different from SnapMirror technology56. References :- ONTAP Select overview, SnapMirror replication for ONTAP Select, Cloud Volumes ONTAP overview, SnapMirror replication for Cloud Volumes ONTAP, Cloud Volumes Service for AWS overview, Azure NetApp Files overview.

To find out how many files are in the NAS volumes of the cluster and how old these files are, you can use the following two tools:

• ONTAP System Manager 9.8 provides a way for admins to find out file system information in any NAS storage volume quickly and easily by enabling a low-impact scanner for each volume. This scanner crawls the ONTAP file system in the background with a low priority job and delivers a wealth of information that is available as soon as you navigate to the volume details page. You can see the file and directory count, the file-age histograms, the capacity use, and other parameters for each volume1.
• ONTAP CLI provides the filestats command that can display a summary of file statistics within a volume on a storage system by reading the file information from a snapshot copy that you specify. You can use various options to filter the output by file size, file type, file age, and so on2.
• Active IQ Config Advisor and Active IQ Unified Manager are not the tools that can fulfill this requirement, as they are mainly used for monitoring and managing the health, performance, and configuration of the cluster, not the file system details of the volumes34. References :- Active IQ Config Advisor, Active IQ Unified Manager, How to report file sizes within a volume using the filestats command, ONTAP 9.8 Feature Overview.

Active IQ Unified Manager is a web-based tool that monitors the health, performance, capacity, and protection of clusters and SVMs. It provides alerts, reports, dashboards, and recommendations to help optimize and troubleshoot the ONTAP environment. Active IQ Unified Manager can be used to validate the deployment of a NetApp AFF A400 cluster by checking the cluster configuration, status, and efficiency1.

Active IQ Config Advisor is a desktop tool that scans the cluster and its components for configuration issues, best practices violations, and potential problems. It generates a report that identifies the errors, warnings, and informational messages along with the suggested actions to resolve them. Active IQ Config Advisor can be used to validate the deployment of a NetApp AFF A400 cluster by verifying the hardware, software, network, and storage settings2.

The other tools are not relevant for validating the deployment of a NetApp AFF A400 cluster. OnCommand Workflow Automation is a tool that automates storage management tasks using predefined or custom workflows. Active IQ Web site is a tool that provides insights and recommendations based on the data collected from NetApp systems34. References :- Active IQ Unified Manager overview, Active IQ Config Advisor overview, OnCommand Workflow Automation overview, Active IQ overview

 The number of ISCSI LIFs that will be created from the SVM setup wizard, as shown in the exhibit, is 16. This is because the LIFs per node field is set to 2, and there are 4 nodes in the cluster. Therefore, the total number of LIFs is 2 x 4 8 for each SVM, and since there are two SVMs, the total number of LIFs is 8 x 2 16. The other options are incorrect because they do not match the calculation based on the exhibit. References :- Configure an SVM for iSCSI, Configure iSCSI on an existing SVM

The igroup is a logical grouping of initiators that can access a set of LUNs. The igroup must contain the IQNs (iSCSI Qualified Names) or WWPNs (World Wide Port Names) of the initiators that need to access the LUNs. In this scenario, the igroup named “ESX” has the iSCSI protocol and the VMware OS type, but it does not have any initiators listed. This means that the VMware hosts cannot authenticate and connect to the LUNs in the SVM. To resolve this issue, the igroup must be populated with the correct initiators that match the VMware hosts. This can be done by using the igroup add command or the System Manager GUI12. References :- Create an igroup, Add initiators to an igroup

 CIFS is the NetApp implementation of the SMB protocol, which enables file sharing between Windows clients and NetApp storage systems. To use CIFS, the storage system must have a valid CIFS license installed and configured. If a node fails on an HA configuration, the surviving node takes over the resources and services of the failed node, including the CIFS server. However, if the surviving node does not have a CIFS license, the CIFS server cannot start and the clients cannot access their data. Therefore, the lack of CIFS license on the surviving node is a possible cause of the problem. References :- CIFS and SMB overview, Licensing overview, Troubleshooting CIFS issues

 The correct way to warm the cache before clients access the cache volume for the first time is to prepopulate the cache volume with data from the origin volume using the flexcache prepopulate start command. This command copies the data blocks from the origin volume to the cache volume in the background, without affecting the client access to the origin volume. The other options are not valid for this scenario because:

• Enabling block-level invalidation using the volume flexcache origin config modify command does not warm the cache, but rather allows the origin volume to invalidate the cached data blocks when they are modified or deleted.
• Copying the data from the origin volume to the cache volume with the NetApp XCP Migration Tool is not recommended, as it can cause data inconsistency and performance degradation. XCP is a data migration tool that can copy data between different types of volumes, such as FlexVol and FlexGroup, but not between FlexCache and origin volumes.
• Synchronizing the origin and cache first with the volume flexcache sync-properties command does not warm the cache, but rather ensures that the cache volume inherits the properties of the origin volume, such as size, security style, and export policy. References :- Prepopulate a FlexCache volume, FlexCache volume concepts, FlexCache volume best practices

The correct action to solve the problem is to update the Selective LUN Map configuration for the LUN mapping. Selective LUN Map (SLM) is a feature that enables you to control which LUNs are visible to which hosts in an ONTAP cluster. SLM reduces the number of paths that are presented to the host and improves the performance and manageability of the SAN environment1. When you perform a volume move, the LUN mapping is automatically updated to include the new node as a destination node, but the old node remains as a source node until the move is completed. This causes ALUA to see twice the number of paths to the LUN, as both nodes are active for the LUN. To avoid this, you need to update the SLM configuration to remove the source node from the LUN mapping after the volume move is done2. Changing the MPIO policy on the host, ensuring that the fabric zoning is correct, or rebooting the host are not actions that would solve the problem, as they do not affect the LUN mapping or the ALUA state. References :- Selective LUN Map overview, How to use Selective LUN Map (SLM) with Volume Move

The point-to-point topology is the simplest and most common way to connect a single host to a storage system using FC. It allows direct communication between two devices without any intermediate devices. The UTA2 ports on the AFF A220 cluster support the point-to-point topology when configured as FC ports. Therefore, to connect a single Windows host directly to the storage using FC, you need to use the point-to-point topology on all ports and make sure that the host and the storage have compatible FC settings, such as speed, WWPN, and zoning. The other options are not correct because they involve additional devices or topologies that are not necessary or supported for this scenario. References :- Quick guide - AFF A220, Detailed guide - AFF A220, ONTAP 9 SAN Configuration Guide

When a LUN has space reservations disabled (a non-space-reserved LUN), and its containing volume has no space guarantee, ONTAP reports the volume usage based on the actual data written to the LUN, not the LUN size. Therefore, ONTAP reports that the volume is using 10 GB of its containing aggregate, and the volume is 10% full. References :- Understanding space reservations for LUNs in System Manager, Recommended volume and file or LUN configuration combinations overview

To find the MAC address of the offline interface e0c, you need to look at the output of the network port show command for Node1, which shows the MAC address and the health status of each port. The MAC address of e0c is 00:a0:98:f1:2e:b2 and its health status is degraded, indicating that it has gone offline. This is the MAC address that you would supply to the engineering team.

• The other MAC addresses are not correct, as they belong to different interfaces or nodes. The MAC address of e0d is 00:a0:98:f1:2e:b3 and its health status is healthy, indicating that it is still online. The MAC address of a0a is 02:a0:98:f1:2e:be and it is the active MAC address of the ifgrp that includes e0c and e0d. The MAC address of ala is 02:a0:98:f1:21:88 and it is the active MAC address of the ifgrp on Node2, which is not relevant to the question. References :- network port show - NetApp, network interface show - NetApp, How does a VIF MAC address get assigned in ONTAP 7?.

File System Analytics is a native ONTAP feature that collects and aggregates data in real time, providing detailed information concerning file and directory count, file-age histograms, capacity use, and other parameters1. You can use ONTAP System Manager to visualize the data using industry standard measures such as hot, warm, and cold2. File System Analytics is available on ONTAP 9.8 and later versions3. Quality of Service, Logical Space Reporting, and volume autosizeare not features that report real-time file counts, but rather features that manage performance, efficiency, and capacity of volumes45 . References :- TR-4867: Best Practice Guidelines for ONTAP FIle System Analytics, File System Analytics overview, File System Analytics feature availability, [Quality of Service overview], [Logical space reporting overview], [Volume autosize overview]

The number of root aggregates that are created during deployment of two NetApp AFF A400 HA pairs is 8. Each AFF A400 HA pair consists of two nodes, and each node has one root aggregate that contains the root volume. Therefore, two AFF A400 HA pairs have 2 x 2 x 2 8 root aggregates in total. The other options are incorrect because they do not match the number of nodes and root aggregates in the scenario. References :- Manage node root volumes and root aggregates, AFF A400 All-Flash Storage Array

 A data LIF is a logical interface that provides data access to clients and applications using various protocols. A data LIF has a service data policy that defines the type of data service that the LIF can provide. In this scenario, to allow object storage access to a bucket that is hosted in ONTAP software, the data LIF must have the data-S3-server service data policy. This policy enables the data LIF to serve S3 requests from clients and applications that use the S3 protocol. The other service data policies are not relevant for this scenario12. References :- Create a data LIF, Service data policies for data LIFs

 A thin-provisioned LUN is one for which storage is not reserved in advance, but allocated dynamically as it is needed. To create a thin-provisioned LUN, the -space-reservation parameter must be set to disabled, which means that the LUN does not reserve any space from the containing volume. The other parameters are either irrelevant or contradictory to thin provisioning. References :- Thin provisioning - NetApp, How to convert a volume or LUN from thick to thin provisioned, ONTAP - Provisioning volumes

To set up a new SnapMirror SVM replication (SVM DR) relationship, you need to have the following SVM subtypes in the source and target clusters:

• The target SVM subtype must be dp-destination, which means that the SVM is a destination for a SnapMirror SVM replication relationship. The dp-destination SVM is a read-only copy of the source SVM and cannot serve data to clients. It can be used for disaster recovery purposes or for cloning data sets1.
• The source SVM subtype must be default, which means that the SVM is a regular SVM that can serve data to clients using various protocols. The default SVM can be the source for a SnapMirror SVM replication relationship, as well as for other types of SnapMirror relationships1.
• The target SVM subtype cannot be sync-destination, as this subtype is used for SnapMirror Synchronous relationships, which are different from SnapMirror SVM replication relationships. SnapMirror Synchronous is a feature that enables zero-recovery point objective (RPO) replication between two volumes on different clusters, while SnapMirror SVM replication is a feature that enables replication of the entire SVM configuration and data between two clusters23.
• The source SVM subtype cannot be sync-source, as this subtype is also used for SnapMirror Synchronous relationships, not for SnapMirror SVM replication relationships23. References :- SVM subtypes, SnapMirror Synchronous overview, About SnapMirror SVM replication.

 To troubleshoot the issue of iSCSI LUNs not visible on the host, you should verify that the iSCSI data protocol has been enabled on the ports and that the controller has not been taken over. If the iSCSI data protocol is disabled on the ports, the storage system will not accept iSCSI connections or requests over those ports. If the controller has been taken over by its partner, the iSCSI LUNs on the taken-over node will not be available to the host. You can use the vserver iscsi connection show command to check the status of the iSCSI connections and the storage failover show command to check the status of the controller. References :- Troubleshoot iSCSI LUNs not visible on the host, vserver iscsi connection show, storage failover show

 To configure data-at-rest encryption for your NetApp ONTAP 9.8 cluster without KMIP services, you need to enable onboard key management and cluster-wide FIPS-compliant mode. Onboard key management allows you to use a passphrase to generate and protect the cluster-wide encryption key, which is used to encrypt the disk encryption keys. Cluster-wide FIPS-compliant mode ensures that the encryption algorithms and modules used by ONTAP are compliant with the Federal Information Processing Standard (FIPS) 140-2. These two actions will satisfy the requirements of data security and passphrase protection for your cluster. References :- NetApp Encryption overview, Configure onboard key management, Enable cluster-wide FIPS-compliant mode

The space allocation option is a LUN attribute that enables the host to communicate with the storage system about the blocks that are no longer in use by the host file system. When the space allocation option is enabled, the host sends SCSI UNMAP commands to the storage system when files are deleted on the disk. The storage system then reclaims the space from the thin-provisioned LUN and makes it available for other LUNs or volumes. This process is also known as space reclamation or hole punching. If the space allocation option is disabled, the host does not send SCSI UNMAP commands and the storage system does not reclaim the space from the thin-provisioned LUN, resulting in a discrepancy between the host and the storage system. References :- Space reclamation, Enable or disable the space allocation option for a LUN
