NEW QUESTION 1

An administrator has a 2node AFF ONTAP cluster named cl1.

• A. Multipathing software is not installed on the host.
• B. Switch zoning does not exist between the host initiator ports and the data LIFs that reside no node cl-01.

NEW QUESTION 4

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?

• A. Interoperability mode is not enabled on the switches
• B. The in-order guarantee is not enabled on the switch
• C. NPV is not enabled on the switches
• D. NPIV is not enabled on the switches

Answer: D

Explanation:
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).

NEW QUESTION 11

A4-node ONTAP FAS9000 cluster was used to serve I/O from six RedHat 7.3 servers. The servers were configured with maximum, queue depth.

NEW QUESTION 12

You need to migrate boot LUNs from a third-party array onto a Netapp FAS8700. Which three actions are required to complete this task? (choose three)

• A. Reboot the third-party SAN to prepare for the LUN Import
• B. Verify third-party array support by using the Interoperability Matrix Tool (IMT)
• C. Convert every FC target port on each controller to an FC initiator port
• D. Convert a single FC port on each controller to an FC initiator port
• E. Create zoning between the third-party array to the FAS8700

Answer: BDE

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
