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
