• Question 1:

  You create a quality of service (QoS) policy group called untest_apps with a maximum throughput of 300 MBps. You add one volume to the policy group, and then you add a second volume to the policy group.

  In this scenario, which statement is true?

  A. The maximum throughput of each volume is 600 MBps.

  B. The combined maximum throughput of both volumes is 600 MBps.

  C. The maximum throughput of each volume is 150 MBps.

  D. The combined maximum throughput of both volumes is 300 MBps.

  Correct Answer: B

  Assuming that the export policy on the storage allows access, you want to enable client access to thefinancevolume in thedepartmentsSVM in the /tmp/fin directory.

  Referring to the exhibit, which UNIX command must be executed to accomplish this task?

  A. mount –t nfs –o nfsvers=3 cluster01:/finance /tmp/fin

  B. mount –t nfs –o nfsvers=3 cluster01:/fin /tmp/fin

  C. mount –t nfs –o nfsvers=3 cluster01:/dept/fin /tmp/fin

  D. mount –t nfs –o nfsvers=3 cluster01:/departments/finance /tmp/fin

  Correct Answer: D

• Question 3:

  There is a node in your cluster that needs to be halted to replace a hardware component? Which two statements are true in this scenario? (Choose two.)

  A. FlashCache data hosted on the failed node will mitigate to its partner.

  B. A FlashPool-enabled volume hosted on the failed node will be taken over by its partner.

  C. A SAN LIF hosted on the halted node will migrate to a healthy node.

  D. An aggregate hosted on the halted node will be taken over by its partner.

  Correct Answer: AB

• Question 4:

  Within ONTAP 9.3, in which two layers would deduplication be applied? (Choose two.)

  A. aggregate a

  B. qtree

  C. LUN

  D. volume

• Question 5:

  You relocate an aggregate to a different node by using the storage aggregate relocate command. In this scenario, which rule applies?

  A. You can only relocate an aggregate that is not assigned to a specific SVM.

  B. You must first break the relationship to move an aggregate that hosts a replication destination.

  C. You can only relocate an aggregate to the HA partner node.

  D. You cannot relocate an aggregate that is hosting a FlexGroup constituent volume.

  Correct Answer: C

• Question 6:

  You want to configure a local cluster to accept SnapMirror transfers from two remote clusters. The two remote clusters have overlapping IP networks and cannot change their IP addressing scheme.

  In this scenario, which action you perform to allow both remote clusters to replicate to the local cluster?

  A. Configure two ONTAP subnets with distinct IP address allocations.

  B. Configure network address translation (NAT) on the network.

  C. Create separate IPspaces on the local cluster.

  D. Configure the SnapMirror relationships as type XDP.

  Correct Answer: C
