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.

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

A customer wants to use FlashCache but does not want to lose the information stored in the FlashCache card when a takeover occurs in a high-availability solution.

What should the customer do to make sure this feature is enabled?

A. Confirm that the aggregates using the FlashCache card are configured appropriately.

B. Set the option to rewarm the FlashCache in both nodes of the HA pair.

C. Verify that the FlashCache card is located in the appropriate slot in the NetApp controller.

D. Verify that the FlashCache card has been configured only on the node where the feature is required.

A. NVRAM

B. FlashCache

C. RAM

D. processors

A FAS6280 running ONTAP 8.0.2 HAS A 32-bit root aggregate. After upgrading to Data ONTAP 8.1, what is the status of the root aggregate?

A. The root aggregate remains 32-bit

B. The root aggregate converts from 32 to 64-bit in place

C. The root aggregate auto-migrates to a new 64-bit aggregate

D. The upgrade fails with a message to create a new 64-bit aggregate before upgrade
