Question No : 1
Which data protocol is available to use on an SVM?

正解:
Explanation: You can configure CIFS and NFS protocols on the Storage Virtual Machine (SVM) to provide file-level data access for NAS clients. To enable CIFS protocol, you must create the data LIFs and the CIFS server. To enable NFS protocol, you can specify the NIS details in addition to the data LIFs.

Question No : 2
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?

正解:

Question No : 3

Question No : 7
You have a cluster with a node running root data partitioning and need to grow the aggregate for additional data volumes.
What is NetApp’s best practice for increasing the aggregate size to optimize performance?

正解:
Explanation: best practices when you add storage to an aggregate optimizes aggregate performance:
Add a complete RAID group at a time.

Question No : 8
An unexpected network outage has occurred and you have lost access to an NFS share inside an SVM on your cluster.
What is causing the problem?

正解:

Question No : 9
You set up a SnapMirror relationship between two clusters and start the SnapMirror initialization. The transfer starts without error and begins replicating data. Before the initialization completes, a network failure occurs and the transfer fails to finish. Once the network failure is corrected, you attempt to initialize the transfer again, but receive the following error:
Volume rep_vol01 is restricted
Which step should you perform before attempting re-initialization?

正解:

Question No : 10
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?

正解:

Question No : 11
Node cl-02 needs to fail over for scheduled maintenance. The node has NAS LIFs on it. The failover needs to be non-disruptive to the NAS clients.
Which command accomplishes this task?

正解:
Explanation: The aggregate relocation can be avoided during this takeover instance by using
the ‑bypass‑optimization parameter with the storage failover takeover command. To bypass aggregate relocation during all future planned takeovers, set the ‑bypass‑takeover‑optimization parameter of the storage failover modify command to true.

Question No : 12
An administrator creates an account for a new user, and wants this user to have limited capabilities accessing SSH. The administrator defined the account, but the user still has full control.
Which two settings would the administrator use to correct this problem? (Choose two.)

正解:

Question No : 13

Which two components should you review to determine what caused the rise in latency? (Choose two.)

正解:

Question No : 14
Which two methods would be used to change root-data partitioning on an FAS2500? (Choose two.)

正解:

Question No : 15
A customer wants to use Storage Efficiency features on volumes used for backup/archive data. The customer is not concerned with performance degradation and is only concerned about storage efficiency.
Which three Storage Efficiency features should be turned on to meet these needs? (Choose three.)
