A storage administrator needs to ensure that an ONTAP FC LUN is accessible for a remote data center. The ISL ports are reporting errors. The trunkshow command output from a Brocade switch is shown below.
On each switch fabric, you must configure the switch ports that connect the Inter-Switch Link (ISL). These ISL ports are otherwise known as the E-ports.

You upgraded your Linux hosts to SUSE Enterprise Linux 15. In this scenario, which two actions should you perform before you test asymmetric namespace access (ANA)? (Choose two)
You are testing FCP paths failures on a 2-node Netapp AFF All SAN Array and verify that persistent ports are correctly enabled. Before testing, a host sees four optimized paths to a LUN. You perform a
node takeover and re-check the host.
Which statement is true after the node takeover?
Support for persistent ports
Beginning in ONTAP 9.8, persistent ports are enabled by default on All SAN Arrays (ASAs) that are configured to use the FC protocol. Persistent ports are only available for FC and require zone
membership identified by World Wide Port Name (WWPN).
Persistent ports reduce the impact of takeovers by creating a shadow LIF on the corresponding physical port of the HA partner. When a node is taken over, the shadow LIF on the partner node assumes the
identity of the original LIF, including the WWPNe. Before the status of path to the taken over node is changed to faulty, the shadow LIF appears as an Active/Optimized path to the host MPIO stack, and I/O is
shifted. This reduces I/O disruption because the host always sees the same number of paths to the target, even during storage failover operations.

Your customer asks you how to connect a host for SAN access to the newly installed AFF A400 system. In this scenario, which two statements are correct? (choose two)
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.

You are configuring a new Netapp ONTAP cluster and are connecting the nodes to Cisco MDS SAN switches. You connect one of the nodes to switch port fc1/11 and run the commands that are shown in the exhibit. The SAN LIFs are enabled but are not operationally online, and none of the SAN hosts can access their LUNs on the ONTAP cluster.
In this scenario, which configuration would cause this problem?
in-order guarantee and interoperability mode are default configuration on a VSAN
NPV is the core switch where NPIV is going to be enabled.
The NPV core switch is defined as an upstream switch on which NPIV is enabled. The NPV core switch receives traffic that is passed to it from a downstream switch that has NPV enabled on it. A switch that is in NPV mode does not switch traffic; instead, it passes traffic to the upstream NPV core switch on which NPIV is enabled.
After NPIV is enabled on the core NPV switch, the port should automatically come up (unless there are other issues).
