NEW QUESTION # 88
A NetApp ONTAP cluster has several data aggregates that contain over 400 data volumes. The aggregates are configured to share a cloud tier to an S3 bucket. All volumes use an automatic policy that moves cold data older than seven days to the object store. During an S3 provider outage, the customer was unable to access their cold data. Which action prevents downtime for each volume when the S3 provider has another outage?
- A. Configure a mirrored aggregate with the SyncMirror feature.
- B. Configure a volume SnapMirror relationship.
- C. Configure FabricPool mirroring.
- D. Configure an SVM SnapMirror relationship.
Answer: C
Explanation:
FabricPool mirroring provides a secondary object store for the cloud tier. If the primary S3 provider becomes unavailable, ONTAP can continue accessing cold data through the mirrored object store, preventing downtime for the volumes.
NEW QUESTION # 89
You must replace a disk shelf due to a hardware fault on a NetApp ONTAP cluster. You replace the shelf with a new shelf that originally belonged to another cluster, and some disks in the new shelf are not showing up as spares. When you run the disk show command, you notice that the new disks have "foreign" ownership. When you attempt to assign the disks, the attempt fails with an ownership conflict error. Which procedure resolves the disk ownership issue and makes the new disks available as spares?
- A. Force disk assignment to the node using the disk assign -disk <disk> -owner <node> force command.
- B. Use a disk wipe operation on the foreign disks, then attempt to assign the disks again.
- C. Zero the disk on the old system before moving it to the new system.
- D. Disable auto-assign, use the disk removeowner command on the foreign disks, and then re- enable auto-assign.
Answer: B
Explanation:
Disks marked with foreign ownership metadata from another cluster can cause ownership conflicts during assignment. Performing a disk wipe clears the old ownership and aggregate metadata, allowing the disks to be reassigned and used as spares in the new cluster.
