  Correct Answer: C

• Question 75:

  alice is a user account used by Alice on a Solaris 11 system.

  sadmin is a role account on the same system.

  Your task is to add the command /usr/sbin/cryptoadm to the Network management profile, so that Alice

  can execute it, while assuming the sadmin role.

  Select the three activities necessary to accomplish this.

  A. To the file /etc/security/prof_attr, add the line: Network Management: solaris:cmd:RO::/usr/sbin/cryptoadm:euid=0

  B. To the file /etc/security/auth_attr, add the line: Network Management: solaris:cmd:RO::/usr/sbin/cryptoadm:euid=0

  C. To the file /etc/security/exec_attr.d/local-entriies, add the line: Network Management: solaris:cmd:RO::/usr/sbin/cryptoadm:euid=0

  D. Run the roles alice to ensure that alice may assume the role sadmin.

  E. Run the command profiles sadmin to ensure that the role sadmin includes the network Management profile.

  F. Run the command profiles alice to ensure that the Alice has permissions to access the Network management profile.

  G. Run the command profiles "Network management" to ensure that the Network management profile includes the sadmin role.

  Correct Answer: CDG

  Explanation: C: /etc/security/exec_attr is a local database that specifies the execution attributes associated with profiles. The exec_attr file can be used with other sources for execution profiles, including the exec_attr NIS map and NIS+ table.

  A profile is a logical grouping of authorizations and com- mands that is interpreted by a profile shell to form a secure execution environment.

• Question 76:

  Select two statements that correctly describe the capabilities of the Distribution Constructor.

  A. ISO images for use with the Automated Installer (AI) can be created.

  B. Bootable USB images can be created for SPARC and x86 architectures.

  C. A single installation server can be used to create ISO images for SPARC and x86 architectures.

  D. Checkpoints can be used to pause the build, allowing scripts to run that modify the resulting ISO Image.

  E. A single Installation server can be used to create ISO images for Solaris 10 and Solaris11 operating systems.

  Correct Answer: AD

  Explanation: A: You can use the distribution constructor to create the following types of Oracle Solaris images:

  *

  (A) x86 or SPARC ISO Image for Automated Installations

  *

  Oracle Solaris x86 live CD image

  *

  x86 or SPARC Oracle Solaris text installer image

  *

  x86 Oracle Solaris Virtual Machine

  Note: You can use the distribution constructor to build custom Oracle Solaris images. Then, you can use the images to install the Oracle Solaris software on individual systems or multiple systems. You can, also, use the distribution constructor to create Virtual Machine (VM) images that run the Oracle Solaris operating system.

  D: Checkpointing Options

  You can use the options provided in the distro_const command to stop and restart the build process at

  various stages in the image-generation process, in order to check and debug the image that is being built.

  This process of stopping and restarting during the build process is called checkpointing.

• Question 77:

  View the Exhibit to inspect the boot environment Information displayed within a non global zone on your system.

  

  Which two options describe the solaris-1 boot environment?

  A. The solaris-1 boot environment is not bootable.

  B. The solaris-1 boot environment is incomplete.

  C. The solaris-1 boot environment was created automatically when the non global zone was created.

  D. The solaris-1 boot environment was created in the non-global zone using the beadm create command.

  E. The solaris-1 boot environment is associated with a non active global zone boot environment.

  Correct Answer: AD

  Explanation: A: The ?of the Active Column indicates that this boot environment is inactive, and hence not

  bootable.

  Note: The values for the Active column are as follows:

  R ?Active on reboot.

  N ?Active now.

  NR ?Active now and active on reboot.

  "-" ?Inactive.

  "!" ?Unbootable boot environments in a non-global zone are represented by an exclamation point.

  D: beadm create

  Creates a new boot environment name, beName.

  Note: beadm list

  Lists information about the existing boot environment, which is beName, or lists information for all boot

  environments if beName is not provided.

  Note: Using beadm Utility (Tasks)

  You can use the beadm utility to create and manage snapshots and clones of your boot environments.

  Note the following distinctions relevant to boot environment administration:

  *

  A snapshot is a read-only image of a dataset or boot environment at a given point in time. A snapshot is not bootable.

  *

  A boot environment is a bootable Oracle Solaris environment, consisting of a root dataset and, optionally, other datasets mounted underneath it. Exactly one boot environment can be active at a time.

  *

  A clone of a boot environment is created by copying another boot environment. A clone is bootable.

• Question 79:

  The crash dump notification on your server is: Documentation states that there should be two core files for each crash dump in the /var/crash directory named vmdump.0 Which command should you choose to display theses two files?

  

  A. savecore -f vmdump.0

  B. dumpadm uncompressed

  C. gunzip vmdump.0

  D. dumpadm -z off

  Correct Answer: A

  Explanation: Decompress using savecore -f vmdump.0

  savecore - save a crash dump of the operating system

  -f dumpfile Attempt to save a crash dump from the speci- fied file instead of from the system's current dump device. This option may be useful if the information stored on the dump device has been copied to an on-disk file by means of the dd(1M) command.

• Question 80:

  Your mentor suggests using the dladm rename-link command to rename the network datalinks.

  What are the two advantages of following this advice?

  A. It can clarify which network interface has what purpose.

  B. It can simplify specifying the network interface with the dladm modify-aggr command.

  C. It can simplify specifying the network interface with the dladm modify-bridge command.

  D. It can simplify IP filter rule changes if the network interface is replaced with a different type.

  E. It can prevent accidental deletion of the network interface with the dladm delete-phys command.

  F. It can prevent accidental deletion of the network interface configuration with the ipadm delete-addr command.

  Correct Answer: AE

  Explanation: A: To rename the bge0 link to mgmt0, enter the following command: # dladm rename-link bge0 mgmt0

  E: Consider that the bge0 device, whose link was named mgmt0 as shown in the previous example, needs to be replaced with a ce0 device because of a hardware failure. The bge0 NIC is physically removed, and replaced with a new ce0 NIC. To associate the newly added ce0 device with the mgmt0 configuration previously associated with bge0, enter the following command:

  # dladm rename-link ce0 mgmt0 Note: How to Rename a Datalink

  Use this procedure if you want to change a datalink name to a customized name. For example, some of the datalinks in upgraded system might have retained legacy hardware- based names and you want to change these names to generic ones.

  Note: dladm rename-link [-R root-dir] link new-link Rename link to new-link. This is used to give a link a meaningful name, or to associate existing link configuration such as link properties of a removed device with a new device.
