Question 1

Which three options are valid methods of installing a Solaris 10 branded zone on a system running Oracle Solaris 11?

A : Use the V2V process to migrate an existing Solaris 8 or 9 non-global zone from a Solaris 10 system to a solaris10 branded zone.

B : Use the V2V process to migrate an existing Solaris 10 non global whole root zone from a Solaris 10 system to a solaris10 branded whole root zone.

C : Install a solaris10 branded zone directly from the Oracle Solaris 10 media.

D : Migrate an existing 64-bit Solaris 10 system to a solaris10 branded non-global zone using the P2V process.

E : Migrate an existing 32 bit Solaris10 system to a solaris10 branded non-global zone using the P2V process.

F : Use the V2V process to migrate an existing Solaris 10 non-global sparse root zone from a Solaris 10 system to a solaris10 branded sparse root zone.

Answer: A,B,D

Question 2

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

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

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

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

Answer: C

Question 3

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 4

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 5

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

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

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

D : If 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 : Load the install/installadm package on the Al server.

Answer: A,D
