NS0-157 Online Practice Questions and Answers

A customer has a 4-node cluster. Two nodes have FlashCache and the other two nodes have Flash Pools. The customer is interested in deploying and OLTP application with a workload that consists of an extreme number of small random writes on four LUNs spread across four volumes.

What should the customer do to improve performance for the OLTP application?

A. Place all volumes for the application on the nodes with Flash Pools.

B. Deploy all volumes for the application on the two nodes with the FlashCache installed.

C. Split the volumes between the two nodes with FlashCache and two of the nodes with Flash Pools.

D. Place the volume with the highest read load on the Flash Pool nodes and place the other volumes on the FlashCache nodes.

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.

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

A. storage virtual machine

B. failover group

C. broadcast domain

D. IPspace

A customer wants the best performance for their Oracle DB solution. They are willing to configure their high-availability nodes so the load is less than 50% per node, to protect performance during failover. They want to enhance read and write performance.

Which NetApp technology accomplishes this task?

A. deduplication

B. thin provisioning

C. Flash Pool

D. FlashCache

A customer enables Storage Efficiency on a volume, intending to use compression only as data is written. The customer observes that compression is working, but deduplication processes are still running on a scheduled basis. The customer wants to use compression without deduplication as the data is written to the volume.

Which action will accomplish this task?

A. Enable post compression on the volume.

B. Create a custom efficiency policy and attach to the SVM.

C. Attach the default efficiency policy to the volume.

D. Attach the inline-only efficiency policy to the volume.

Which feature is NOT supported by clustered Data ONTAP 8.2?

A. Synchronous SnapMirror

B. Data Protection Mirrors

C. Load Sharing Mirrors

D. Non-disruptive upgrades

What are the four replicated database rings in a cluster? (choose four)

A. administrator

B. logical-interface manager (lifmgr)

C. management application (mgmt)

D. protocol management daemon (prtodb)

E. SAN management deamon (bcomd)

F. virtual-interface manager (vifmgr)

G. volume location database (vldb)

Which protocol(s) does Infinite Volumes support?

A. All supported protocols on Data ONTAP

B. NFSv3 and NFSv4 only

C. NFSv2 and NFSv3 only

D. File access and protocol improvements

E. NFSv3 and SMB 1.0 only

To support multi-tenancy, an administrator must create or enable which type of unique login account?

A. vsadmin, for the cluster

B. admin, for each Vserver

C. admin, for the cluster

D. vsadmin, for each vserver

SnapVault backup of a clustered Data ONTAP 8.2 or later system is done at what data set level?

A. Aggregate

B. Directory
