You have a Netapp ONTAP cluster and are configuring ISCSI for some new hosts . You want to ensure that ISCSI connectivity can survive physical network failures.
In this scenario, which two features would help fulfill this requirement? (choose two)
Answer : C, D
Broadcast Domains are used to segment and create failover groups automatically... Broadcast Domain do not guarantee redundancy on ISCSI because failover groups are not used on ISCSI.
What are two benefits of implementing VLANs for ISCSI configuration? (choose two)
Answer : A, C
When you implement VLANs in large IP network infrastructures, you derive the following benefits:
Increased security.
VLANs enable you to leverage existing infrastructure while still providing enhanced security because they limit access between different nodes of an Ethernet network or an IP SAN.

Referring to the exhibit, which two actions would you perform to ensure that each host has valid multipathing? (choose two)
Answer : A, B
Iscsi is already started, we can not run those commands successfully if the protocol is not started
ALUA is enabled on hosts, It is not enabled on switches
VLANs are configured on the Netapp and switches, they need to be properly configured on both sides to work correctly

You are designing a new 4-node AFF A400 SAN cluster with 20 ISCSI hosts. Each AFF A400 node will have four data LIFs. Each ISCSI host needs to access every LUN over two LIFs per node on every
SAN node.
In this scenario, which Netapp SAN feature enable this connectivity?
Answer : A
SLM will choose 4 LIFs per node, being 8 LIF total (owner and HA partner), enabling portsets will help to limit the ports per node... that way we can stablish only 2 LIF per node.
Creating port sets and binding igroups to port sets
In addition to using Selective LUN Map (SLM), you can create a port set and bind the port set to an igroup to further limit which LIFs can be used by an initiator to access a LUN. If you do not bind a port set
to an igroup, then all of the initiators in the igroup can access mapped LUNs through all of the LIFs on the node owning the LUN and the owning node's HA partner.

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?
Answer : A
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.
