Q6. 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?

A. Svccfg-s filesystem/shadowd:default

setprop config_params/shadow_threads=integer: 16

end

svcadm refresh filesystem/shadowd: default

B. Specify the-b <blocksize> option with the zfs create command and increase the value of

<blocksize>

C. Use the-o -volblocksize=<blocksize>option with the zfs create command and increase the value

of the default <blocksize>.

D. Svccfg-s filesystem/zfs: default

setprop config_params/shadow_threads = integer: 16

end

svcadm refresh filesystem/zfs:default

Q10. View the exhibit to inspect the file system configuration on your server.

You department's backup policy is to perform a full backup to a remote system disk on Saturday.

On each weekday, you are to perform an incremental backup to the same remote system disk.

Each incremental backup will contain only data that has been modified since the previous Saturday backup.

The server file systems must remain available at all times and can never be taken offline.

The backup must not only provide for the recovery of the most recent version of a file, but must also allow recovery of previous versions of a file.

Following your company policy, which two describe the correct procedure to be performed on each weekday for backing up the /data file system to a remote disk named /remote/backup?

A. Remove the previous daily snapshot.

zfs snapshot pool1.data@daily

zfs send-i pool1/data@sat pool1/data@daily > /remote/backup/full

B. Remove the previous daily snapshot.

zfs snapshot pool1.data@daily

zfs send-i pool1/data#sat pool1/data@daily | zfs recv remote /backup/ ‘date ‘+%m%d%’

C. Remove the previous daily snapshot.

zfs snapshot pool1.data@daily

zfs send-i pool1/data@sat pool1/data@daily > /remote/backup/daily

D. Remove the previous daily snapshot.

zfs create-i pool1/data@sat pool1/data@daily

zfs send pool1/data@daily | zfs remote/backup
