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

C : 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

After installing the OS, you boot the system and notice that the syslogd daemon is not accepting messages from remote systems.

Which two options should you select to modify the syslogd daemon configuration so that it accepts messages from remote systems?

A : svccfg -s svc:/system/system -log setprop start/exec= ''syslogd -t''Restart the syslogd daemon.

B : Set the following parameter in the /etc/syslogd.conf file: LOG_FROM_REMOTE= YESRestart the syslogd daemon.

C : svcadm enable svc:/system/system -log/config/log_from_remoteRestart the syslogd daemon.

D : svccfg -s svc:/system/system-log setprop config/log_from_remote=trueRestart the syslogd daemon.

E : Set the following parameter in the /etc/default/syslogd file: LOG_FROM_REMOTE=YESRestart the syslogd daemon.

Answer: B,D

Question 3

You have Solaris 11 system with a host name of sysA and it uses LDAP as a naming service.

You have created a flash archive of sysA and you want to migrate this system to an Oracle Solaris11 server, Solaris10 branded zone.

The zone Status on the Oracle Solaris 11 server is:

- zone10 incomplete /zone/zone1 solaris10 exc1

Select the option that will force the non-global zone to prompt you for a host name and name service the first time it is booted.

A : zonecfg to change the zonename before booting the system for the first time

B : the - u option with the zoneadm - z zone10 attach command.

C : the -u option with the zoneadn -z zone10 install command

D : move the sysidcfg file from the /root directory before booting the non-global zone.

Answer: C

Question 4

You want to deploy Oracle Solans 11 with the Automated Installer (Al). You need to make sure that your server and network meet the requirements for using Al Choose the three options that describe the requirements for using Al. (Choose three.)

A : u must set up DHCP. The DHCP server and Al install server can be the same machine or two different machines.

B : u can create only one manifest per install service. If you need more than one manifest, create multiple install services.

C : minimum requirement to operate as an Al install server is 1 GB of memory.

D : two client machines have different architectures and need to be installed with the same version of the Oracle Solaris 11 OS( then create two Al manifests and a single install service.

E : ad the install/installadm package on the Al server.

Answer: A,D

Question 5

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

C : 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 : cryption 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.
