An SVM is created for FCP traffic. LUNs must be created to share with ESXi hosts for datastores. Which two items must be configured after the LUN is created, for this to happen? (Choose two.)
For configuring LUNs to share with ESXi hosts for datastores in an SVM created for FCP traffic, the following steps are necessary after creating the LUN:
Create an igroup with the ESXi hosts' WWPNs: This step involves defining an initiator group that includes the WWPNs of the ESXi hosts that need access to the LUN.
Map the LUNs to the igroup: This step assigns the LUN to the created igroup, allowing the ESXi hosts to access the LUN.

NetApp Documentation on LUN and igroup Configuration
When using tagged VLANs on Cisco Nexus switches for NVMe over TCP, which two changes must be made to enable jumbo frames? (Choose two.)
For enabling jumbo frames on Cisco Nexus switches for NVMe over TCP with tagged VLANs, the following changes are required:
Modify the Cisco Nexus switches to use an MTU of 9216: Setting the MTU to 9216 ensures that the network can handle jumbo frames, reducing the number of packets needed for large data transfers and thus improving performance.
Modify the appropriate broadcast domain in NetApp ONTAP software to use an MTU of 9216: This setting must match the network configuration to ensure end-to-end support for jumbo frames, which is essential for optimizing performance in NVMe over TCP environments.
For additional information, refer to:
NetApp Documentation on NVMe over TCP

An administrator finishes an installation of a new NetApp ASA system at the customer site and creates a new LUN. The customer wants to restrict the access of the LUN to specific UFs.
Where would the administrator configure this?
To restrict access to a newly created LUN to specific hosts, the administrator should configure the igroup (initiator group). An igroup is used to control which initiators (hosts) are allowed to access specific LUNs. This ensures that only authorized hosts can access the storage, enhancing security and access control.

An administrator creates a new volume and a LUN for an SAN-connected application that uses snapshots. The application has fast-growing data that is constantly being populated and deleted afterwards.
Which option can be set to manage the space automatically?
To manage space automatically for a volume containing a LUN with fast-growing data, enabling automatic resizing on the volume is recommended. This feature allows the volume to grow dynamically as needed, accommodating the fluctuating data size without manual intervention. This helps in managing storage efficiently and ensures that the application has the required space.

NetApp Documentation on Volume Management

A storage engineer is required to provide NetApp site design documentation to show that the NetApp ONTAP SAN solution was delivered as intended.
Which NetApp tool can the storage engineer use to automate the creation of a difference report?
Active IQ OneCollect is a NetApp tool designed to collect configuration and performance data from your storage environment, including SAN solutions. It can automate the creation of difference reports by capturing the current state of the system and comparing it against a baseline, thereby showing any changes or deviations from the intended design.
