Question 1

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:defaultsetprop config_params/shadow_threads=integer: 16endsvcadm 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: defaultsetprop config_params/shadow_threads = integer: 16endsvcadm refresh filesystem/zfs:default

Answer: A

Question 2

Identify the correct procedure for breaking the /prod_data mirror, removing c4tOdO and c4t2d0, and making the data on c4t0d0 and c4t2d0 accessible under the /dev_data mount point

A : zpool split pooll pool2 c4t0d0 c4t2d0 zpool import pool2 zfs set mountpomt=/dev_data pool2/prod_data

B : zpool detach pooh pool2 zpool attach pool2 zfs set mountpoint=/dev_data pool2/prod_data

C : zfs split pool1/prod_data -n pool2/dev_data zfs set mountpomt=/dev_data pool2/prod_data

D : zpool split pooh pool2 c4t0d0 c4t2d0 zpool import pool2

Answer: A

Question 3

You upgraded your server to Oracle bolans 11 and you imported a zpool(pooll) that was created in bolaris 10. You need to create an encrypted ZFS file system in pooll, but first you need to make sure that your server supports ZFS encryption.

Which four statements are true for support of ZFS encryption?

A : The encrypted file system must have been created in Oracle Solaris 11. To encrypt a ZFS file system from a previous version of Solaris, upgrade the zpool and create a new encrypted ZFS file system in that zpool Finally, move or copy the data from the existing ZFS file system into the new encrypted ZFS file system.

B : if you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 30, minimum

C : ZFS encryption is integrated with the ZFS command set and no additional packages need to be installed.

D : ZFS encryption requires that the ZFS Dataset Encryption package be installed.E If you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 21, minimum. D f Encryption is supported at the pool or dataset (file system) level

E : Encryption is supported at the pool level only and every file system in the pool will be encrypted.

F : You cannot create an encrypted file system in a zpool that was created prior to Oracle Solaris 11.Create a new zpool in Solaris 11, create an encrypted ZFS file system in the new zpool, and move or copy the data from the existing file system into the new encrypted file system.

Answer: A,B,C

Question 4

Consider the following rule file for use with the Basic Audit Reporting Tool (BART).

CHECK all

IGNORE dirmtime

/etc/security

/etc/notices
