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 : 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 3

Review the output from a ZFS file system:

NAMEPROPERTYVALUESOURCE

pool1/encryptencryptionaes-256-ccmlocal pool1/encryptkeysourceraw,file///mykeylocal

You need to recreate the pooM/encrypt file system exactly as it is listed above Which two commands can you use to recreate the pooM/encrypt file system?

(Choose two.)

A : tool genkey keystone=file outkey=/mykey keytype=aes keylen=256

B : nkey pktool keystore=file outkey=/mykey keytype=aes keylen=256

C : create -o encryption=aes-256-ccm -o keysource=raw,file://mykey pooll/encrypt

D : create -o encryption=aes-256-ccm -o keysource=raw,file:///mykey pooM/encrypt

E : create -o encryption=aes-256-ccm -o keysource=raw,file:///mykey source=local pooll/encrypt

Answer: B,C

Question 4

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 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?

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

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

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

D : readm ---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

Answer: A
