• Question 206:

  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:

  A. Change the state of the destination volume to online.

  B. Delete all Snapshot copies on the destination volume.

  C. Change the state of the destination volume to offline.

  D. Delete all data in the destination volume.

  Correct Answer: B

• Question 208:

  A customer has an aggregate, aggr1_01 with three RAID groups: rg0, rg1, and rg2. Each RAID group has 15 disks, and the aggregate's maximum RAID group size is set to 18 disks. The customer adds three additional disks to the aggregate using the following command:

  storage aggregate add-disks –aggregate aggr1_01 –diskcount 3

  How are the RAID groups affected by this command?

  A. The disks are added to a new RAID group rg3.

  B. Each RAID group receives one additional disk.

  C. The three disks are added to RAID group rg2.

  D. The three disks are added to RAID group rg0.

  Correct Answer: B

• Question 209:

  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.

  Correct Answer: D
