  Which type of LIF allows replication between two clusters?

  A. cluster

  B. cluster-mgmt

  C. data

  D. intercluster

  E. node-mgmt

• Question 102:

  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.

  Correct Answer: D

  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.
