Q41. - (Topic 2) 

View the Exhibit to inspect the boot environment Information displayed within a non global zone on your system. 

Which two options describe the solaris-1 boot environment? 

A. The solaris-1 boot environment is not bootable. 

B. The solaris-1 boot environment is incomplete. 

C. The solaris-1 boot environment was created automatically when the non global zone was created. 

D. The solaris-1 boot environment was created in the non-global zone using the beadm create command. 

E. The solaris-1 boot environment is associated with a non active global zone boot environment. 

Answer: A,D 


A: The – of the Active Column indicates that this boot environment is inactive,and hence not bootable. 

Note: The values for the Active column are as follows: R – Active on reboot. 

N – Active now. 

NR – Active now and active on reboot. 

“-” – Inactive. 

“!” – Unbootable boot environments in a non-global zone are represented by an exclamation point. 

D: beadm create 

Creates a new boot environment name,beName..

Note: beadm list 

Lists information about the existing boot environment,which Name,or lists information 

for all boot environments not provided..

Note: Using beadm Utility (Tasks) 

You can use the beadm utility to create and manage snapshots and clones of your boot 


Note the following distinctions relevant to boot environment administration: 


 A snapshot is a read-only image of a dataset or boot environment at a given point in time. A snapshot is not bootable. 


 A boot environment is a bootable Oracle Solaris environment,consisting of a root dataset and,optionally,other datasets mounted underneath it. Exactly one boot environment can be active at a time. 


 A clone of a boot environment is created by copying another boot environment. A clone is bootable. 

Q42. - (Topic 2) 

You wish to troubleshoot some issues that you are having on the system. You want to monitor the /var/adm/messages file in real time. Which command would you use to do this? 

A. head 

B. tail 

C. cat 

D. file 

E. test 



tail is a program on Unix and Unix-like systems used to display the last few lines of a text file or piped data. 

By default,tail will print the last 10 lines of its input to the standard output. With command line options the number of lines printed and the printing units (lines,blocks or bytes) may be changed. The following example shows the last 20 lines of filename: tail -n 20 filename 

Q43. - (Topic 1) 

You are currently working in both your home directory and the system directory /tmp. You are switch back and forth with full path names. Which pair of cd commands will provide you with a shortcut to switch between these two locations? 

A. cd ~ and cd – 

B. cd and cd. 

C. cd ~ and cd 

D. cd * and cd . . 



In the Bourne Again,C,Korn,TC,and Z shells,the tilde (~) is used as a shortcut for 

specifying your home directory. 

cd – 

It's the command-line equivalent of the back button (takes you to the previous directory you 

were in). 


To make certain that you are in your home directory,type the cd (change directory) 

command. This command moves you to your home (default) directory. 

Q44. - (Topic 1) 

Oracle Solaris 11 limits access to the system with usernames and passwords 

The usernames are held in ___________,and the passwords are held in ___________. 

Select the correct pair. 

A. /etc/security/policy.conf /etc/passwd 

B. /etc/passwd /etc/shadow 

C. /etc/security /etc/passwd 

D. /etc/shadow /etc/passwd 



The /etc/passwd file contains basic user attributes. This is an ASCII file that contains an entry for each user. Each entry defines the basic attributes applied to a user. 

/etc/shadow file stores actual password in encrypted format for user's account with additional properties related to user password i.e. it stores secure user account information. All fields are separated by a colon (:) symbol. It contains one entry per line for each user listed in /etc/passwd file. 

Q45. - (Topic 2) 

What is the output of the following command,if executed using the default shell for the root role account of a standard Live CD Install of Oracle Solaris 11? 

echo '$SHELL' 

A. /usr/bin/bash 

B. /usr/bin/ksh 


D. the PID for the current shell 



Single quotes are most strict. They prevent even variable expansion. Double quotes prevent wildcard expansion but allow variable expansion. For example: #!/bin/sh echo $SHELL echo "$SHELL" echo '$SHELL' This will print: /usr/bin/bash /usr/bin/bash $SHELL 

Q46. - (Topic 2) 

Given the following output of the zpool status command:

D. The configuration is a bug in Solaris 11; it cannot be created by an administrator. 


Q47. - (Topic 1) 

Which option displays the result of running the zfs list command? 

A. Option A 

B. Option B 

C. Option C 

D. Option D 



The zfs list command provides an extensible mechanism for viewing and querying dataset information. 

You can list basic dataset information by using the zfs list command with no options. This command displays the names of all datasets on the system and the values of their used,available,referenced,and mountpoint properties. For more information about these properties,see Introducing ZFS Properties. 

For example: # zfs list NAME USED AVAIL REFER MOUNTPOINT pool 476K 16.5G 21K /pool pool/clone 18K 16.5G 18K /pool/clone pool/home 296K 16.5G 19K /pool/home pool/home/marks 277K 16.5G 277K /pool/home/marks pool/home/marks@snap 0 - 277K -pool/test 18K 16.5G 18K /test

A. pkg verify p7zip 

B. pkg fix p7sip 

C. pkg rebuild-index p7zip 

D. pkg revert p7zip 

E. pkg uninstsll p7zip

A. zoneadm list –icv dbzone 

B. zones tat –c summary dbzone 

C. zonecfg –z dbzone info 

D. zonecfg –icv dbzone info 



zonecfg info Display information about the current configuration. If resource-type is specified,displays only information about resources of the relevant type. If any property-name value pairs are specified,displays only information about resources meeting the given criteria. In the resource scope,any arguments are ignored,and info displays information about the resource which is currently being added or modified. 

Note: zonecfg –z zonename. Specify the name of a zone. Zone names are case sensitive. Zone names must begin with an alphanumeric character and can contain alphanumeric characters,the underscore (_) the hyphen (-),and the dot (.). The name global and all names beginning with SUNW are reserved and cannot be used. 

Incorrect answer: 

A: The zoneadm utility is used to administer system zones. A zone is an application 

container that is maintained by the operating system runtime. 

list option: 

Display the name of the current zones,or the specified zone if indicated. 

B: No such command. 

D: no such options zonecfg –icv 

Q50. - (Topic 2) 

User1 is attempting to run the following command: 

cp bigfile verybig 

The system displays the following errer: 

cp: cannot create verybig: Disc quota exceeded 

Your initial troubleshooting shows that the df -h command indicates the account is at 100% capacity. What command would you use to determine how much disk space the user has available? 

A. zfs get quota rpool/export/home/user1 

B. zfs userused@user1 

C. zfs quota=1M /rpool/export/home/user1 

D. df –h | grep user1 



ZFS quotas can be set and displayed by using the zfs set and zfs get commands. In the following example,a quota of 10 Gbytes is set on tank/home/bonwick. 

# zfs set quota=10G tank/home/bonwick # zfs get quota tank/home/bonwick NAME PROPERTY VALUE SOURCE tank/home/bonwick quota 10.0G local
