Netapp Updated NS0-522 Exam Questions and Answers by harris

For a two-node cluster serving iSCSI LUNs, it is recommended to create two iSCSI LIFs per node. This configuration provides redundancy and load balancing, ensuring that each node can handle failover scenarios effectively and maintain high availability for the iSCSI connections.

Separate VLANs are a recommended design practice for IP-based SAN traffic because they provide logical network segmentation and enable independent broadcast domains. ONTAP VLANs can separate storage traffic by function or network path even when the underlying physical switching infrastructure is shared. For SAN redundancy, NetApp also recommends separate Ethernet networks and multiple paths so that failure of one network does not eliminate storage connectivity. VLAN separation additionally limits unnecessary broadcast-domain exposure and provides clearer operational boundaries for iSCSI or NVMe/TCP traffic. An MTU of 1500 is supported but does not inherently provide the requested security and reliability improvement, while simply using routed networking is not the relevant SAN best practice. Therefore, separate VLANs provide the appropriate segmentation and path-isolation characteristics for an AFF ASA IP SAN design.

To configure an SVM to use NVMe/FC, the following steps are necessary:

Add the FC protocol: This step involves enabling the Fibre Channel protocol on the SVM, which is required to support NVMe over Fibre Channel.

Create an NVMe/FC LIF: Logical Interfaces (LIFs) must be created to handle NVMe traffic over the Fibre Channel network. These LIFs enable the NVMe namespace access to the host systems.

These steps ensure that the SVM is correctly set up to use NVMe/FC, allowing for efficient and high-performance access to NVMe storage.

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.
