• Question 281:

  You notice your indirect I/O performance between nodes in your 4-node cluster is slowing down from prior week. Each node has two 10 GB connections to the cluster interconnect, one to each switch. You are using four out of 12 available ports on each cluster interconnect switch. Your cluster network utilization is over 80%.

  What should you do to increase cluster interconnect performance?

  A. Change the SFP+ from 10 Gb to 16 Gb on each node and switch.

  B. Add two more cluster interconnect connections per node.

  C. Add additional ISLs between the two cluster interconnect switches.

  D. Change the cable from TwinAx to optical with SFP+ for better throughput.

  Correct Answer: B

• Question 282:

• Question 283:

  You create an SVM named svm7. Its DNS name is ntap7. In svm7, you create a volume named vol1 with a junction path of /users.

  An NFS client would mount the root of vol1 using which path?

  A. svm7:/users

  B. ntap7:/users

  C. ntap7:/vol1

  D. svm7:/vol1

  Correct Answer: A

• Question 284:

  Which statement is true about establishing a SnapMirror relationship in clustered data ONTAP?

  A. It sets up the relationship, but does not start the initial transfer

  B. It sets up the relationship on the source node only

  C. It sets up the relationship and starts the initial data transfer

  D. It sets up the relationship and creates the destination volume

  Correct Answer: A

• Question 285:

  A company has a vault relationship between ClusterA and ClusterB. After a month of operations, the SnapVault update fails. The primary and secondary volumes have been thin provisioned and are reporting available space. There is connectivity between ClusterA and ClusterB.

  What caused the update failure?

  A. The primary volume's aggregate is full.

  B. The secondary volume's aggregate is full.

  C. A cluster peering relationship was not refreshed every month.

  D. There are 251 Snapshot copies on the destination SnapVault.

  Correct Answer: C

• Question 286:

  A customer has a 1000 GB volume that is at 25% capacity and has no existing Snapshot copies. The customer creates a Snapshot copy of the volume, creates a new 250 GB file, and deletes an existing 100 GB file.

  How much space is free in the volume?

  A. 350 GB

  B. 400 GB

  C. 500 GB

  D. 600 GB

  Correct Answer: C

• Question 287:

  Which two must already exist before creating a subnet? (Choose two.)

  A. storage virtual machine

  B. failover group

  C. broadcast domain

  D. IPspace

  Correct Answer: CD

  Reference: http://www.bradreese.com/how-to-subnet-a-network.pdf

  The IPspace feature enables a single storage system to be accessed by clients from more than one disconnected network, even if those clients are using the same IP address.

  An IPspace defines a distinct IP address space in which vFiler units can participate. IP addresses defined for an IPspace are applicable only within that IPspace. A distinct routing table is maintained for each IPspace. No cross-IPspace traffic routing happens.

• Question 288:

  A customer wants to retire a broadcast domain called bcast1 from the cluster. All network ports and data LIFs previously using bcast1 have been moved to another broadcast domain. When the administrator attempts to delete the broadcast domain, the deletion fails.

  What is causing the problem?

  A. TheIPspace, that the broadcast domain uses, still exists.

  B. The cluster ports are using the bcast1 broadcast domain.

  C. There are still subnets associated with the broadcast domain.

  D. The SVM has not been deleted.

  Correct Answer: A

• Question 289:

  What is the speed of the cluster interconnect ports on a FAS2552?

  A. 10 Gb

  B. 1 Gb

  C. 8 Gb

  D. 16 Gb

  Correct Answer: B

• Question 290:

  What is the default privileged account used to manage a clustered Data ONTAP storage system?

  A. administrator

  B. root

  C. admin

  D. pseudo root

  Correct Answer: C

  The default cluster account admin an alternative administrative user account username Reference: https://library.netapp.com/ecm/ecm_download_file/ECMP1196798
