The broadcast-domain split command allows you to create a new broadcast domain by moving one or more ports from an existing broadcast domain to the new one. In this scenario, you can use this command to move the e0e and e0c ports from the Default broadcast domain to a new broadcast domain in the same IPspace. This would satisfy the requirement of creating a new broadcast domain with the specified ports. The other options are not valid for this scenario, as they either create a new broadcast domain without moving any ports (A), merge two existing broadcast domains into one (D), or require a graphical user interface ©. References :- network port broadcast-domain split, Create a broadcast domain

 You can use ONTAP System Manager or the command line interface to disable the unused Ethernet ports in an ONTAP 9.8 cluster. ONTAP System Manager is a web-based graphical user interface that enables you to manage storage systems, clusters, and resources. The command line interface is a text-based interface that enables you to perform administrative tasks using commands. Both methods allow you to modify the network port settings and remove the ports from the broadcast domain. Active IQ Config Advisor and Active IQ Unified Manager are not methods to disable the unused Ethernet ports, but tools to monitor and optimize the cluster performance and configuration. References :- Monitor the reachability of network ports in ONTAP 9.8 and later, Map network ports using ONTAP 9.8 or later, Map network ports using ONTAP 9.7 or earlier

The problem of being unable to upload large files or migrate VMs to the new NFS datastore is likely caused by a mismatch in the maximum transmission unit (MTU) settings between the network switches, the ONTAP cluster, and the vSphere hosts. The exhibit shows that the broadcast domain for the NFS LIF has an MTU of 9,000 bytes, which means that it is configured for jumbo frames. However, the default MTU for the VMkernel ports on the vSphere hosts is 1,500 bytes, which means that they are not configured for jumbo frames. This can result in packet fragmentation, dropped packets, or reduced performance. To correct the problem, the MTU of the VMkernel ports on the vSphere hosts should be changed to 9,000 bytes to match the MTU of the broadcast domain and the network switches. This will enable the vSphere hosts to send and receive jumbo frames and improve the NFS performance. References :- ProvisionNFS storage for VMware datastores, vSphere NFS datastore - Version 3 with ONTAP, Configure jumbo frames for VMkernel networking

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.

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

 NetApp ONTAP Select is a software-only version of ONTAP that can run on commodity servers with direct-attached storage. It supports both block and file protocols, including NFS, NVMe, and CIFS. SCSI and FCP are not supported by ONTAP Select. References :- ONTAP Select overview, Client protocols, Software-Defined Storage with ONTAP Select

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
