Q91. - (Topic 1) 

Which command would you use from the bash shell to determine the total amount of physical memory installed in your Solaris system (x86 and SPARC)? 

A. uname –a 

B. prtconf | grep –i memory 

C. sysdef | grep –i memory 

D. vmstat 

E. prtdiag | grep –i memory 

Answer:

Explanation: 

The prtconf command prints the system configuration informa-tion. The output includes the total amount of memory,and the configuration of system peripherals formatted as a dev-ice tree. 

If a device path is specified on the command line for those command options that can take a device path,prtconf will only display information for that device node. 


Q92. - (Topic 1) 

You need to know the IP address configured on interface net3,and that the interface is up. Which command confirms these? 

A. ipadm show-if 

B. ipadm up-addr 

C. ipadm show-addr 

D. ipadm enable-if 

E. ipadm refresh-addr 

F. ipadm show-addrprop 

Answer:

Explanation: 

Show address information,either for the given addrobj or all the address objects configured on the specified interface,including the address objects that are only in the persistent configuration. 

State can be: disabled,down,duplicate,inaccessible,ok,tentative 

Example: # ipadm show-addr ADDROBJ TYPE STATE ADDR lo0/v4 static ok 127.0.0.1/8 lo0/v6 static ok ::1/128 


Q93. - (Topic 2) 

Which four can the SMF notification framework be configured to monitor and report? 

A. all service transition states 

B. service dependencies that have stopped or faulted 

C. service configuration modifications 

D. legacy services that have not started 

E. services that have been disabled 

F. service fault management events 

G. processes that have been killed 

Answer: A,E,F,G 

Explanation: 

Note 1: State Transition Sets are defined as: 

to<state> 

Set of all transitions that have <state> as the final state of the transition. 

form-<state> 

Set of all transitions that have <state> as the initial state of the transition. 

<state> 

Set of all transitions that have <state> as the initial state of the transitional. 

Set of all transitions. (A) 

Valid values of state are maintenance,offline (G),disabled (E),online and degraded. An 

example of a transitions set definition: maintenance,from-online,to-degraded. 

F: In this context,events is a comma separated list of SMF state transition sets or a comma separated list of FMA (Fault Management Architecture) event classes. events cannot have a mix of SMF state transition sets and FMA event classes. For convenience,the tags problem- {diagnosed,updated,repaired,resolved} describe the lifecycle of a problem diagnosed by the FMA subsystem - from initial diagnosis to interim updates and finally problem closure. 

Note 2: SMF allows notification by using SNMP or SMTP of state transitions. It publishes Information Events for state transitions which are consumed by notification daemons like snmp-notify(1M) and smtp-notify(1M). SMF state transitions of disabled services do not generate notifications unless the final state for the transition is disabled and there exist notification parameters for that transition. Notification is not be generated for transitions that have the same initial and final state. 


Q94. - (Topic 2) 

United States of America export laws include restrictions on cryptography. 

Identify the two methods with which these restrictions are accommodated in the Oracle Solaris 11 Cryptographic Framework. 

A. Corporations must utilize signed X.509 v3 certificates. 

B. A third-party provider object must be signed with a certificate issued by Oracle. 

C. Loadable kernel software modules must register using the Cryptographic Framework SPI. 

D. Third-party providers must utilize X.509 v3 certificates signed by trusted Root Certification Authorities. 

E. Systems destined for embargoed countries utilize loadable kernel software modules that restrict encryption to 64 bit keys. 

Answer: B,C 

Explanation: 

B: Binary Signatures for Third-Party Software The elfsign command provides a means to sign providers to be used with the Oracle Solaris Cryptographic Framework. Typically,this command is run by the developer of a provider. 

The elfsign command has subcommands to request a certificate from Sun and to sign binaries. Another subcommand verifies the signature. Unsigned binaries cannot be used by the Oracle Solaris Cryptographic Framework. To sign one or more providers requires the certificate from Sun and the private key that was used to request the certificate. 

C: Export law in the United States requires that the use of open cryptographic interfaces be restricted. The Oracle Solaris Cryptographic Framework satisfies the current law by requiring that kernel cryptographic providers and PKCS #11 cryptographic providers be signed. 


Q95. - (Topic 2) 

You have been asked to do an orderly shutdown on a process with a PID of 1234,with the kill command. 

Which command is best? 

A. kill -2 1234 

B. kill -15 1234 

C. kill -9 1234 

D. kill -1 1234 

Answer:

Explanation: 

On POSIX-compliant platforms,SIGTERM is the signal sent to a process to request its termination. The symbolic constant for SIGTERM is defined in the header file signal.h. Symbolic signal names are used because signal numbers can vary across platforms,however on the vast majority of systems,SIGTERM is signal #15. 

SIGTERM is the default signal sent to a process by the kill or killall commands. It causes the termination of a process,but unlike the SIGKILL signal,it can be caught and interpreted (or ignored) by the process. Therefore,SIGTERM is akin to asking a process to terminate nicely,allowing cleanup and closure of files. For this reason,on many Unix systems during shutdown,init issues SIGTERM to all processes that are not essential to powering off,waits a few seconds,and then issues SIGKILL to forcibly terminate any such processes that remain. 


Q96. - (Topic 2) 

Which two capabilities are provided by the OpenBoot PROM? 

A. a command to safely shut down the system 

B. hardware testing and initialization 

C. booting from a disk or network 

D. starting the GRUB loader 

Answer: B,C 

Explanation: 

OpenBoot firmware is executed immediately after you turn on your system. The primary tasks of OpenBoot firmware are to: 

*

 Test and initialize the system hardware (B) 

*

 Determine the hardware configuration *Boot the operating system from either a mass storage device or from a network (C) *Provide interactive debugging facilities for testing hardware and software 


Q97. - (Topic 1) 

The default publisher on your system is: 

You want to update the Oracle Solaris 11 environment on your system,but you are not able to connect this system to the Internet to access the default Oracle repository. A repository has been created on your local network and is named http://server1.example.com. 

Which command would you choose to connect your system to the local repository? 

A. pkg publisher to specify the new publisher 

B. pkg set-publisher to set the stickiness on the http://server1.example.com publisher and unset stickiness for http://pkg.oracle.com/solaris/release 

C. pkg add-publisher to add the new publisher 

D. pkg set-publisher to set the origin for the publisher 

Answer:

Explanation: 

Solaris 11 Express makes it pretty easy to set up a local copy of the repository. 

A common reason folks need access to a local repository is because their system is not 

connected to the Internet. 

Tthe pkg set-publisher command can be used to for example add a publisher or to enable 

or disable a publisher. 

Note: Example Adding a Publisher 

Use the -g option to specify the publisher origin URI. 

# pkg set-publisher -g http://pkg.example.com/release example.com 

Example Specifying the Preferred Publisher 

Use the -P option to specify a publisher as the preferred publisher. The specified publisher 

moves to the top of the search order. You can specify the -P option when you add a 

publisher or you can modify an existing publisher. 

# pkg set-publisher -P example.com 

Example Enabling or Disabling a Publisher 

Use the -d option to disable a publisher. The preferred publisher cannot be disabled. A 

disabled publisher is not used in package operations such as list and install. Youcan modify 

the properties of adisabled publishers. 

Use the -e option to enable a publisher. 

# pkg set-publisher -d example2.com 


Q98. - (Topic 1) 

user1 has a disk quota of 0.5 MB. The user attempts to run the following command on a file called .bigfile that is 495 KB in size: 

cp bigfile /tmp 

Will the command execute successfully? 

A. Yes. Quotas do not include any of the system files such as /tmp /swap. 

B. Yes. The quota is set at the directory level,not the user level. 

C. No. The command will fail because it will cause him to exceed his user quota. 

D. No. A user cannot place files into the /tmp directory. 

Answer:

Explanation: 

UFS quotas enable system administrators to control the size of file systems. Quotas limit the amount of disk space and the number of inodes,which roughly corresponds to the number of files,that individual users can acquire. For this reason,quotas are especially useful on the file systems where user home directories reside. As a rule,the public and /tmp file systems usually do not benefit significantly by establishing quotas. 

Note: The cp command copies files and directories. 


Q99. - (Topic 1) 

The su command by default makes an entry into the log file for every su command attempt. The following is a single line from the file: 

SU 12/18 23:20 + pts/1 user1-root 

What does the + sign represent? 

A. unsuccessful attempt 

B. successful attempt 

C. The attempt was from a pseudo terminal,and not the console. 

D. The attempt was from a user that is in the adm group,same as root. 

E. Time zone is not set. 

Answer:

Explanation: 

The sulog file,/var/adm/sulog,is a log containing all attempts (whether successful or not) of the su command. An entry is added to the sulog file every time the su command is executed. The fields in sulog are: date,time,successful (+) or unsuccessful (-),port,user executing the su command,and user being switched to. In the preceding example,all su attempts were successful,except for the attempt on 2/23 at 20:51,when user pete unsuccessfully attempted to su to user root. 

Look for entries where an unauthorized user has used the command inappropriately. The following entry shows a successful (indicated by +) su from user userid to root. 

SU 03/31 12:52 + pts/0 <userid>-root 


Q100. - (Topic 2)
