Oracle Exam 1Z0-820 Topic 7 Question 92 Discussion

Actual exam question for Oracle's 1Z0-820 exam

Question #: 92
Topic #: 7

You created a new zpool. Now you need to migrate the existing ZFS file system from pool1/prod to pool2/prod.

You have these requirements:

1. Users must have access to the data during the migration, so you cannot shutdown the file system while the migration takes place.

2. Because you want to copy the data as quickly as possible, you need to increase the server resources devoted to the ZFS migration.

Which method would you use to modify the ZFS shadow migration daemon defaults to increase the concurrency and overall speed of migration?

ASvccfg - s filesystem/shadowd:default
setprop config_params/shadow_threads=integer: 16
end
svcadm refresh filesystem/shadowd: default

BSpecify the -b <blocksize> option with the zfs create command and increase the value of <blocksize>

CUse the -o -volblocksize=<blocksize>option with the zfs create command and increase the value of the default <blocksize>.

DSvccfg -s filesystem/zfs: default
setprop config_params/shadow_threads = integer: 16
end
svcadm refresh filesystem/zfs:default

I think option B is also a viable solution, as increasing the block size could potentially improve the migration speed as well.

I'm not sure, but option D also seems like a valid choice to increase the concurrency for the migration.

I agree with Stevie. Increasing the shadow_threads to 16 would definitely help speed up the migration process.

The correct answer is A. Modifying the shadow migration daemon defaults to increase the concurrency and speed of the migration makes sense, as the question specifically asks for a method to do this.
