Netapp NS0-520 Actual Questions

Best practice: NPIV is required for FC LIFs to operate correctly. Before creating FC LIFs, make sure that any fabrics attached to an ONTAP system have NPIV enabled.

Changing the Network port settings at the broadcast domain level will change all ports in that broadcast domain sequentially, or one at the time. This will only cause a disruption if the port is a single point of

failure.

Enable jumbo frames (typically MTU of 9000).All devices in the data path, including initiators, targets, and switches, must support jumbo frames. Otherwise, enabling jumbo frames actually reduces network

performance substantially.

ISCSI-Direct-attachment: In a direct-attached configuration, one or more hosts are directly connected to the controllers.

You cannot directly attach FC or FC-NMVE SAN hosts to single nodes without using an FC switch.

The quorum rule states that to make changes to the configuration in our cluster, we need to have more than half of the nodes available. This prevents configuration conflicts if we lose connectivity between the nodes in our cluster.

So, if we have only 2 racks and 4 nodes we could never get more than half of the nodes available if one of those racks power fails.

We need 6 nodes separated on 3 racks, so we can have more than half of the nodes available if one of those racks power fails.
