E.
Create zoning between the third-party array to the FAS8700
Answers
Suggested answer: B, D, E

Explanation:

We only need to convert one FC to initiator per node, if you need to enable multipath with 2 switches, then you need 2 ports on initiator mode per node

D.

Answers
Suggested answer: B, D

Explanation:

Zoning the host using WWNNs is not recommended. Netapp always recommends to use WWPN to zone correctly.

We can not stablish a queue depth value because we don't have the amount of ports and hosts to calculate the recommended queue depth Installing VSC and updating the HBA driver are best practices recommended by Netapp You can find more information on this link:

An administrator has migrated an ISCSI LUN with Foreign LUN Import (FLI) tool. The migrated LUN is presented on the new system, but it is not visible to the host. In this scenario which additional action must be completed to make the

D.

D.
Map the LUN to an ISCSI igroup
Answers
Suggested answer: D

Explanation:

Installing ANA is related with NVMe protocol

Binding an igroup to a port set will only limit our paths

Stopping the FCP service will not affect at anything, because this is an ISCSI LUN When you migrate ISCSI using FLI, you need to map the LUNs to an igroup where the destination arrays is added, after the LUN has been imported, you can create a new iSCSI igroup and add the hosts to the igroup You can find more information on this link:

Suggested answer: A, C

Explanation:

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.

Explanation:

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.

Answers
Suggested answer: A

Explanation:

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.

Suggested answer: B

Explanation:

Before using your UTA ports on a FC infraestructure, you need to modify the current mode from CNA to FC. You need to set the ports offline before you modify that parameter.

Suggested answer: C

Explanation:

We would not be able to run that command if NVMe is not enabled

NVMe is supported on the same SVM along with FC protocol

The multipath tool on NVMe is called ANA

NQN needs to be correctly declared on the subsystem to map the new NVMe resources
