Q121. - (Topic 2) 

Which two options are valid methods of installing a solaris10 branded zone on a system running Oracle Solaris 11? 

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. 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: B,C 

Explanation: 

B: How to Migrate an Existing native Non-Global Zone 

Use the V2V process to migrate an existing zone on your Solaris 10 system to a solaris10 brand zone on a system running the Oracle Solaris 11 release. 

C: How to Install the solaris10 Branded Zone 

A configured solaris10 branded zone is installed by using the zoneadm command with the install subcommand. 


Q122. - (Topic 2) 

Which three options describe the purpose of the zonep2vchk command? 

A. Used on a Solaris 10 global zone to access the system for problems before migrating that system to a Solaris 10 branded zone. 

B. Used to access a Solaris 10 global zone for problems before migrating that zone to a Solaris 11 global zone 

C. Used to create zonecfg template for a Solaris 10 global zone that that will be migrated to a solaris10 branded zone. 

D. Used to migrate an Oracle Solaris 11 global zone to a non-global zone. 

E. Used to migrate a Solaris 10 global zone to a non-global zone on the same server; the non-global zone can then be migrated to a Solaris 11 server as a Solaris10 branded zone. 

Answer: C,D,E 

Explanation: 

zonep2vchk 

-check a global zone's configuration for physical to virtual migration into non-global zone 

The.zonep2vchk.utility is used to evaluate a global zone's configuration before the process of physical-to-virtual (p2v) migration into a non-global zone. The p2v process involves archiving a global zone (source),and then installing a non-global zone (target) using that archive Zonep2vchk.serves two functions. First,it can be used to report issues on the source which might prevent a successful.p2v.migration. Second,it can output a template.zonecfg,which can be used to assist in configuring the non-global zone target. Zonep2vchk.can be executed on a Solaris 10 or later global zone. To execute on Solaris 10,copy the.zonep2vchkutility to the Solaris 10 source global zone. When run on Solaris 10,a target release of.S11.can be specified,which will check for.p2v.into a Solaris 10 Branded zone. 


Q123. - (Topic 2) 

Which two are user definable OpenBoot parameters that can be set in the OpenBoot 

PROM? 

A. IP address for the system console 

B. Host ID 

C. System date and time 

D. Default boot device 

E. Verbose hardware diagnostics 

F. Powering off the hardware 

Answer: D,E 

Explanation: 

The NVRAM chip stores user-definable system parameters,also referred to as NVRAM 

variables or EEPROM parameters. The parameters allow administrators to control 

variables such as the default boot device and boot command. The NVRAM also contains 

writeable areas for user-controlled diagnostics,macros,and device aliases. NVRAM is 

where the system identification information is stored,such as the host ID,Ethernet 

address,and time-of-day (TOD) clock. 

Examples of NVRAM variables: 

Variable Default Description boot-device disk or net 

The device from which to start up. 

diag-device net The diagnostic startup source device. 

diag-file Empty string Arguments passed to the startup program in diagnostic mode. 

diag-switch? false Whether to run in diagnostic mode 


Q124. - (Topic 2) 

You have been asked to troubleshoot the initial configuration of a virtual network connecting two local zones with the outside world. 

View the exhibit. 

The command 

dladm create-vnic -1 vswitch192.168.1 vnic1 

fails with the error 

dladm: invalid link name ‘vswitch192.168.1’ 

What is the reason for this error? 

A. The name vswitch192.168.1 is not legal. 

B. The zone must be specified withdladm create-vnic -z zone3 vnic1. 

C. The virtual interface must be specified withdladm create-vnic -z zone3 vnic1. 

D. The virtual interface must be created withipadm create-vnic -1 switch192.168.1. 

E. The virtual switch must be created first withdladm create -etherstub vswitch192.168.1. 

Answer:

Explanation: 

There is no data-link named vswitch192.168. 

We need to create an etherstub first. 

See Note and example below for details. 

Note: Create a VNIC in the system's global zone. 

# dladm create-vnic -l data-link vnic-name data-link is the name of the interface where the VNIC is to be configured. -l link,--link=link 

link can be a physical link or an etherstub. 

vnic-name is the name that you want to give the VNIC. 

For example,to create a VNIC named vnic0 on interface e1000g0,you would type the 

following: # dladm create-vnic -l e1000g0 vnic0 Example: Creating a Virtual Network Without a Physical NIC First,create an etherstub with name stub1: # dladm create-etherstub stub1 Create two VNICs with names hello0 and test1 on the etherstub. This 

operation implicitly creates a virtual switch connecting hello0 and 

test1. # dladm create-vnic -l stub1 hello0 # dladm create-vnic -l stub1 test1 


Q125. - (Topic 1) 

Oracle Solaris 11 kernel encounters a fatal error,and it results in a system panic. 

What type of file does this generate? 

A. a.out 

B. objdump 

C. core dump 

D. tape dump 

E. crash dump 

Answer:

Explanation: 

A kernel panic is a type of error that occurs when the core (kernel) of an operating system receives an instruction in an unexpected format or when it fails to handle properly. A kernel panic can also follow when the operating system can’t recover from a different type of error. A kernel panic can be caused by damaged or incompatible software or,more rarely,damaged or incompatible hardware. 

When a server kernel panics it abruptly halts all normal system operations. Usually,a kernel process named panic() outputs an error message to the console and stores debugging information in nonvolitile memory to be written to a crash log file upon restarting the computer. Saving the memory contents of the core and associated debugging information is called a “core dump.” 


Q126. - (Topic 1) 

You want the system to generate an email notification each time one of the services has changed its state. Which option would send an email message to the system administrator whenever a service changes to the maintenance state? 

A. Use the setsc command in ALOM to enable the mail alerts to be sent to a specified email address whenever the fault management facility detects a service change to the maintenance state. 

B. Make an entry in the /etc/syslog.conf file to instruct syslogd to send an email alert when it receives a message from the SMF facility that a service has changed to the maintenance state. 

C. Use the svccfg setnotify command to create a notification and send an email when a service enters the maintenance state. 

D. Use the scvadm command to enable the notification service. Set the –g maintenance option on the netnotify service to send an email when a service enters the maintenance state. 

Answer:

Explanation: 

This procedure causes the system to generate an email notification each time one of the services or a selected service has a change in state. You can choose to use either SMTP or SNMP. Normally,you would only select SNMP if you already have SNMP configured for some other reason. 

By default,SNMP traps are sent on maintenance transitions. If you use SNMP for monitoring,you can configure additional traps for other state transitions. 

1.

 Become an administrator or assume a role that includes the Service Management rights profile. 

2.

 Set notification parameters. 

Example: The following command creates a notification that sends email when transactions go into the maintenance state 

# /usr/sbin/svccfg setnotify -g maintenance mailto:sysadmins@example.com 


Q127. - (Topic 2) 

When issuing the zonestat 2 1h is command,the following information is displayed: 

Which two options accurately describe the statistics contained in the output? 

A. dbzone is using 0.21% of the total CPU resource available in the zone's processor set. 

B. dbzone is using 0.21% of the global zone's total CPU. 

C. dbzone is using 5.48% of the total physical memory that has been allocated to the zone. 

D. dbzone is using 2.37% of the global zone's total virtual memory. 

E. The network is being utilized 100% with no physical bandwidth remaining. 

Answer: A,C 

Explanation: 

A: %PART The amount of cpu used as a percentage of the total cpu in a processor-set to which the zone is bound. A zone can only have processes bound to multiple processor sets if it is the global zone,or if psrset(1m) psets are used. If multiple binding are found for a zone,it's %PART is the fraction used of all bound psets. For [total] and [system],%PART is the percent used of all cpus on the system. 

Note: The zonestat utility reports on the cpu,memory,and resource control utilization of the currently running zones. Each zone's utilization is reported both as a percentage of system resources and the zone's configured limits. 

The zonestat utility prints a series of interval reports at the specified interval. It optionally also prints one or more summary reports at a specified interval. 


Q128. - (Topic 2) 

How should you permanently restrict the non-global zone testzone so that it does not use more than 20 CPU shares while it is running? 

A. While configuring the zone,add this entry:add rct1set name = capped.cpu-sharesadd value (priv = privileged,limit = 20,action = none)endexit 

B. While configuring the zone,add this entry: add rct1set name= zone.cpu-sharesadd value (priv=privileged,limit=20,action=none)endexitfrom command line,enter: # dispadmin - d FSS 

C. From the command line enter: #prct1 -n zone.cpu-shares - r - v 20 - i zone testzone 

D. From the command line,enter:#prct1 - n zone.cpu-shares - v 80 - r - i zone global 

Answer:

Explanation: 

The.prctl.utility allows the examination and modification of the resource controls associated 

with an active process,task,or project on the system. It allows access to the basic and 

privileged limits and the current usage on the specified entity. 

How to Change the.zone.cpu-shares.Value in a Zone Dynamically 

This procedure can be used in the global zone or in a non-global zone. 

For more information about roles,see.Configuring and Using RBAC (Task Map) in.System 

Administration Guide: Security Services. 

# prctl -n zone.cpu-shares -r -v value -i zone zonename 

idtype.is either the.zonename.or the.zoneid..value.is the new value. 

Note: project.cpu-shares 

Number of CPU shares granted to a project for use with the fair share scheduler

Explanation: 

A: + Indicates the file/directory was added in the later dataset 

C: R Indicates the file/directory was renamed in the later dataset 

E: - Indicates the file/directory was removed in the later dataset 

G: M Indicates the file/directory was modified in the later dataset 

Note: Identifying ZFS Snapshot Differences (zfs diff) 

You can determine ZFS snapshot differences by using the zfs diff command. 

The following table summarizes the file or directory changes that are identified by the zfs diff command. 

File or Directory Change Identifier 

*

 File or directory is modified or file or directory link changed M 

*

 File or directory is present in the older snapshot but not in the newer snapshot — 

*

 File or directory is present in the newer snapshot but not in the older snapshot + 

*

 File or directory is renamed R
