The correct answer is A. Modify the SnapMirror policy's -keep parameter. D. The SnapMirror relationship has reached its maximum number of snapshots, which is 255. The SnapMirror destination volume has hit the maximum allowed number of Snapshot copies, which is typically 255 for most ONTAP systems.

Question
You have set up SnapMirror relationships between two clusters. SnapMirror shows as unhealthy and fails with the following error:
Reason: 'Transfer failed'. Last Transfer Error Was 'The number of Snapshot copies on destination volume "volume_name" has reached the maximum supported count of <count_set_by_policy>. When you check the EMS logs, you notice the following:
[NetAppProdVault-01: worker_thread_342: sm.xfer.fail.maxlim.snap:alert]: The number of Snapshot copies on destination volume 'SVM_filer02:vflsystems_sm_4' of the relationship with relationship UUID 'ala620fc-a870-lle9-94ef-00a09893ee91' and policy 'filer02_vault_daily_policy' has reached the maximum supported. [NetAppProdVault-01: sm_logger_main: smc.snapmir.update.fail:error]: Snapmirror update from source volume 'vol1' to destination volume 'vol2' failed with error 'The number of Snapshot copies on destination volume "vol2" has reached the maximum supported count of <count_set_by_policy>.'. Relationship UUID 'ala620fc-a870-lle9-94ef-00a09893ee91'. What is the cause of this situation, and how can you avoid this in the future? (Choose two.)
Options
- AModify the SnapMirror policy's -keep parameter.
- BThe SnapMirror relationship has reached its maximum number of snapshots, which is 1019.
- CModify the SnapMirror policy's -snapmirror-label parameter.
- DThe SnapMirror relationship has reached its maximum number of snapshots, which is 255.

Explanation
The SnapMirror destination volume has hit the maximum allowed number of Snapshot copies, which is typically 255 for most ONTAP systems. This causes transfers to fail with a "Snapshot copy limit reached" error. To avoid this issue in the future: Adjust the -keep parameter in the SnapMirror policy to control how many Snapshot copies are Implement a retention policy that matches your schedule and storage capacity.
