Q94. - (Topic 1)
An unexpected network outage has occurred and you have lost access to an NFS share inside an SVM on your cluster.
What is causing the problem?

B. The MTU setting for the port is incorrect.
C. The failover group does not have the proper targets defined.
D. The current port is already hosting a LIF.
Answer: C
Q95. - (Topic 3)
A storage administrator create a Quality of Service ( QoS) policy named pgMB300 which
sets a maximum throughput of 300MB/s, and a second Quality of Service policy named pglO200 which sets the maximum throughput to 200 IOPS. The storage administrator assigns the pgMB300 QoS policy to Vserver vs1. The storage administrator then attempts to assign the pglO200 QOS policy to vol1 of vs1.
What is the outcome?
A. The attempt will succeed. You can assign Qos policy to storage object so long as single object does not have multiple policy groups assigned to it.
B. The attempt will fail. You cannot have policies with differently maximum throughput units. They all have to be MB/s or all have to be IOPS.
C. The attempt will succeed. You can nest IOPS policy limit instead a MB/s policy limit.
D. The attempt will fail. You cannot nest policy groups in any manner.
Answer: D
Explanation: Explanation/Reference:
In the following illustration, the Vserver vs3 is assigned to policy group pg2. You cannot
assign volumes vol4 or vol5 to a policy group because an object in the storage hierarchy
(Vserver vs3) is assigned to a policy group.

Q98. - (Topic 3)
Which is a supported management switch? (Choose two)
A. Brocade 8000
B. Brocade FLS624
C. Cisco Nexus 5010
D. Cisco Nexus 7000
E. Cisco Catalyst 2960
F. Cisco Nexus 5020
Answer: E,F
Explanation: The NX5010 and NX5020 are cluster switches with 10Gbps ports.On the other hand these switches are reached their end of support and NX5596 is advised by NetApp. As I know the first 8 ports of NX5010 and the first 16 ports of NX5020 are 1/10Gbitps ports, so theoretically both can connect the management ports, but officially Netapp NS0-157 : Practice Test
they are not management switches.
