Question 1
When setting up Automated Installer (Al) clients, an interactive tool can be used to generate a
custom system configuration profile. The profile will specify the time zone, date and time, user and
root accounts, and name services used for an Al client installation. This interactive tool will prompt
you to enter the client information and an SC profile (XML file) will be created.
Which interactive tool can be used to generate this custom configuration?
- A. sys-unconfig
- B. installadm set-criteria
- C. sysconfig create-profile
- E. installadm create-profile
Answer:
C
Question 2
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:
E
Question 3
Review the zonestat command
zonestat -q -r physical-memory -R high -z dbzone -p -p "zones" 10 24h 60m
Select the option that correctly describes the information that is displayed by this command
- A. It is a sample of dbzone's physical memory usage taken every hour over a 24-hour period Only the top 10 samplings of peak memory usage are displayed. All other utilization data is eliminated
- B. It is a sample of dbzone's CPU, virtual memory, and networking utilization Physical memory is excluded from the report The sampling is taken every 10 minutes over a 24 hour period and peak utilization is displayed each hour.
- C. ft is a sample of dbzone's CPU, virtual memory, and networking utilization Physical memory is excluded from the report. The sampling is taken every 10 seconds over a 24-hour period and displayed each hour.
- D. It is a sample of dbzone's memory and CPU utilization every 10 seconds over a 24-hour period Only peak virtual memory usage and CPU utilization are displayed each hour All other utilization data is eliminated.
- E. it is a sample of dbzone's physical memory usage taken every 10 seconds over a 24-hour period. Only peak memory usage is displayed each hour All other utilization data is eliminated.
Answer:
E

Answer:
A
Question 5

Question 6

To simplify administration of a network, the decision was made to use bridging rather than routing
Your network includes three Oracle Solaris 11 systems,
en-tiny cib uiiuyo yiuviumy reuunuaiu pauiways.
You previously created the bridges on each system with the following commands:
SystemA#dladmcreate-bridge-1 netl -1 net2 bridgeA
SystemB # dladm create-bridge -1 netl -1 net2 bndgeB
SystemC # dladm create-bridge -1 netl -1 net2 bndgeC
You notice that network performance is less than expected, and packets between networks X and Z
are being forwarded by bridgeA and bridgeB, rather than being forwarded directly by bndgeC.
Select the solution
- A. SystemC # dladm modify-bndge -p stp bridgeC
- B. SystemA # dladm modify-bridge -p stp bridgeA SystemB # dladm modify-bridge -p stp bndgeB SystemC # dladm modify-bridge -p stp bridgeC
- C. SystemC # dladm modify-bridge -p trill bridgeC
- D. SystemA # dladm modify-bridge -p trill bridgeA SystemB # dladm modify-bridge -p trill bndgeB SystemC # dladm modify-bridge -p trill bndgeC
- E. SystemC # ipadm set-prop -p forwarding=on bridgeC
- F. SystemC # dladm set-linkprop -p promiscuous=on bridgeC
Answer:
E
Question 7
A non-global zone named testzone is currently running.
Which option would you choose to dynamically set the CPU shares for the zone to two shares?
- A. While logged in to the global zone, enter: prctl -n zone.cpu-shares -v 2 -r -i zone testzone
- B. While logged in to the global zone, enter: zonecfg -z testzone add rctl set name=zone cpu-shares setvalue=(priv=privilegedJimit=2,action=none)
- C. While logged in to the global zone, enter: prctl -n 2 zone cpu-shares -i zone testzone
- D. While logged in to the global zone, enter: zonecfg -z testzone add rctl set name-zone cpu-shares set value=2
