Answer: B,C

Question 3

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 : 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

Answer: A

Question 4

When setting up Automated Installer (AI) clients, an interactive tool can be used to generate a custom system configuration profile. The profile will specify the time zone, data and time, user and root accounts, and name services used for an AI client installation.

Which interactive tool can be used to generate this question configuration?

A : sys-unconfig

B : installadm set-criteria

C : sysconfig create-profile

D : installadm create-profile

Answer: B

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 : 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
