Question 25

- (Exam Topic 3)
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?

Correct 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.

Question 26

- (Exam Topic 3)
You are configuring a VMware sphere host for FC access to a Netapp ONTAP cluster. In this scenario, which two tasks does Netapp recommend performing on the Vsphere host? (choose two)

Correct Answer:BD
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

A customer's Red Hat Linux 7.0 server's Linux native DM-MP settings for multi pa thing have not been set correctly. In this scenario, what would cause this problem?

Correct Answer:D

Question 28

- (Exam Topic 3)
You have an existing 8-node Netapp Cluster serving NFS data, and you want to expand your cluster by an additional four nodes to serve ISCSI. In this scenario, where would you validate this configuration?

Correct Answer:D
Hardware Universe shows how many nodes and which filers are compatible to mix between them

Question 29

- (Exam Topic 1)
Click the Exhibit button.
NS0-520 dumps exhibit
During pre-deployment testing, you want to ensure that all FC paths are available to your host. You use the network interface modify -vserver SVM1 -lif LIF_top-0f -admin-state up command to correct the configuration shown in the exhibit.
What happens when using this command?

Correct Answer:C

Question 30

- (Exam Topic 2)
An enterprise customer has both a NetApp FAS8200 4-node cluster and a third-party storage array in a shared SAN environment. The host servers connect to both storage vendors' arrays in the fabric.
Regarding (he hosts in this scenario, what are- two NetApp best practices when performing this task? (Choose two.)

Correct Answer:AD
