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.)

Options :

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

Question 2

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

Options :

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 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?

Options :

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

Answer: A

Question 4

You need to remove the gzip software package.

Before you remove the package, you want to create a backup of the operating environment.

Which IPS command should you use?

Options :

A : Use the pkg remove command with the -require-backup-be option

B :

Use the beadm create command to create a new boot environment

Use the pkg remove command to remove the gzip package from the current boot environment.

C :

Use the luucreate command to create a new boot environment.

Use the pkgrm command to remove the gzip package from the current boot environment

D : Use the pkg unmstall command with the -backup-be-name option

Answer: B

Question 5

A process associated with a user application keeps crashing on the user, but a core dump is not being saved in the /var/core/pprocess directory. The core dump configuration is:

global core file pattern: /var/core/core. %f.%p

global core file content: default

init core file pattern: core

init core file content: default

global core dumps: enabled

per-process core dumps: enabled

global setid core dumps disabled

per-process setid core dumps: disabled

global core dump logging: disabled

Which option would change the core dump configuration so that a user's per-process core dumps get saved in the /var/core/pprocess directory?

Options :

A : coreadm ---g /var/core/pprocess/core.%f %p

B : coreadm ---i /var/core/pprocess/core.%f.%p

C : coreadm ---i /var/core/pprocess/core.%f.%p coreadm ---e proc---setid ---d process

D : coreadm ---g /var/core/pprocess/core.%f.%p coreadm ---e global---setid

E :

Make this change to the /etc/coreadm conf file:

init core file pattern: /var/core/pprocess/core.%f.%p
