  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.

  Correct 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 132:

  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

  Correct Answer: BF

• Question 133:

  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.

  Correct Answer: CE

  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 LINK IPKTS RBYTES INTRS POLLS CH<10 CH10-50 CH>50

  Note: dlstat show-link [-r [-F] | -t] [-i interval] [-a] [-p] [ -o field[,...]] [-u R|K|M|G|T|P] [link] Display statistics for

  a link.

  -r

  Display receive-side statistics only. Includes bytes and packets received, hardware and software drops,

  and so forth.

  List of supported RX fields:

  link

  iusedby

  ibytes

  ipkts

  intrs

  polls

  hdrops: hardware drops

  sdrops: software drops (owing to bandwidth enforcement) ch<10: number of packet chains of length < 10

  ch10-50: number of packet chains of length between 10 and 50 ch>50: number of packet chains of length

  > 50
