QUESTION 1
Which modification needs to be made to the Service Management Facility before you publish a new package to the IPS repository?
A. The pkg.depotd must be disabled.
B. The pkg/readonly property for the application/pkg/server service must be set to false
C. The pkg/writable_root property for the application/pkg/server service must be set to true.
D. The pkg/image_root property for the application/pkg/server service must be set to the location of the repository.
Answer: D
Explanation: pkg/image_root (astring) The path to the image whose file information will be used as a cache for file data.
Reference: man pkg.depotd
QUESTION 2
For an Oracle Solaris 11 Automated Installation (Al), select the two properties that can be configured using System Configuration profiles (SC profiles). (Choose two.)
A. IP address of the Al server
B. passwords for user accounts
C. target disk slice for installation
D. NWAM active network configuration profile (NCP)
E. IP address of the IPS (Image Packaging System) repository
F. SI_MANIFEST_SCRIPT, which defines the URL of the manifest script
Answer: B,F
QUESTION 3
You run the command dlstat show-link -r.
Select the two correct statements regarding the information displayed in the INTRS column.
A. No value is listed for virtual network interfaces.
B. A value of 0 is listed for virtual interfaces and ether stubs.
C. The number of Interrupts is listed, which indicates network efficiency.
D. A number equal to the number of transmitted Ethernet frames is listed for physical links.
E. The number of packets that were interrupted by a collision is listed, which may indicate hardware problems.
Answer: C,E
Explanation: In this output, the statistics for interrupt (INTRS) are significant. Low interrupt numbers indicate
greater efficiency in performance. If the interrupt numbers are high, then you might need to add more resources
to the specific link.
Example:
# dlstat -r -i 1

B. You can create only one manifest per install service. If you need more than one manifest, create multiple install services.
C. The minimum requirement to operate as an Al install server is 1 GB of memory.
D. If two client machines have different architectures and need to be installed with the same version of the Oracle Solaris 11 OS( then create two Al manifests and a single install service.

WARNING: The zone.cpu-shares rctl is set but FSS is not the default scheduling class for this zone. FSS will
be used for processes in the zone but to get the full benefit of FSS, it should be the default scheduling class.
Which option will resolve this issue?
A. in the global zone, run this command to change the process scheduler for the global zone dispadmin -d FSS
B. in the non-global zone, run this command to change the process scheduler for this specific zone: dispadmin –
d FSS
C. Change the zone resource control to:
value: (priv=privileged,limit=20,action=none,default)
