• Question 31:

  You are troubleshooting the Oracle Solaris11 Automated Installer (AI), which is not connecting with the IPS software repository.

  Which three steps will help determine the cause of DNS name resolution failure?

  A. Verify the contents of /etc/resolve.conf.
  B. Run netstat -nr to verify the routing to the DNS server.
  C. Ping the IP address of the IPS server to verify connectivity.
  D. On the installation server, verify that the menu.1st file for the client points to a valid boot arc hive.
  E. Run df -k to verify that the boot directory containing the boot archive is loopback mounted under /etc/netboot.
  F. Run the command /sbin/dhcpinfo DNSserv to ensure that the DHCP server providing the DNS server information.
  A. Verify the contents of /etc/resolve.conf.
  B. Run netstat -nr to verify the routing to the DNS server.
  F. Run the command /sbin/dhcpinfo DNSserv to ensure that the DHCP server providing the DNS server information.

  Check DNS

  *

  (A) Check whether DNS is configured on your client by verifying that a non-empty /etc/resolv.conf file exists.

  *

  (F) If /etc/resolv.conf does not exist or is empty, check that your DHCP server is providing DNS server information to the client:

  # /sbin/dhcpinfo DNSserv

  If this command returns nothing, the DHCP server is not set up to provide DNS server information to the client. Contact your DHCP administrator to correct this problem.

  *

  (B) If an /etc/resolv.conf file exists and is properly configured, check for the following possible problems and contact your system administrator for resolution:

  ** The DNS server might not be resolving your IPS repository server name. ** No default route to reach the DNS server exists.

• Question 32:

  After installing the OS, you boot the system and notice that the syslogd daemon is not accepting messages from remote systems. Which two options should you select to modify the syslogd daemon configuration so that it accepts messages from remote systems?

  A. svccfg -s svc:/system/system -log setprop start/exec= "syslogd -t" Restart the syslogd daemon.
  B. Set the following parameter in the /etc/syslogd.conf file: LOG_FROM_REMOTE= YES Restart the syslogd daemon.
  C. svcadm enable svc:/system/system -log/config/log_from_remote Restart the syslogd daemon.
  D. svccfg -s svc:/system/system-log setprop config/log_from_remote=true Restart the syslogd daemon.
  E. Set the following parameter in the /etc/default/syslogd file: LOG_FROM_REMOTE=YES Restart the syslogd daemon.
  B. Set the following parameter in the /etc/syslogd.conf file: LOG_FROM_REMOTE= YES Restart the syslogd daemon.
  D. svccfg -s svc:/system/system-log setprop config/log_from_remote=true Restart the syslogd daemon.

  ---

  B: The /etc/default/syslogd file contains the following default parameter settings. See FILES.

  LOG_FROM_REMOTE

  Specifies whether remote messages are logged. LOG_FROM_REMOTE=NO is equivalent to the -t command-line option. The default value for LOG_FROM_REMOTE is YES.

• Question 33:

  ServerA contains two ISO images of a package repository named so1.repo.iso-a and so1.repo.iso-b respectively. You need to create a single local package repository on server that clients can connect to. The package repository will be stored on the /export/IPS file system and named repo. The preferred publisher will be named solaris and the publisher URL will be http://serverA.example.com.

  Which is the correct procedure to perform on ServerA to create the local Package repository?

  A. cat so1.repo.iso-a sol.repo.iso-b > so1.full.iso Mount the ISO image and use the rsync command to extract the contents of the ISO file to the /export/IPS file system. Set the pkg/inst_root property to /export/IPS/repo and the pkg/readonly property to true. Set the preferred publisher by using pkg set-publisher -G http://pkg.oracle.com/solaris/release/ \ -g http"//serverA.example.com/ solaris
  B. cat so1.repo.iso-a so1.repo.iso-b > /export/IPS/repo Set the pkg/inst_root property to true and the pkg/readonly property to /export/IPS Set the preferred publisher by using pkg set-publisher -G http://serverA.example.com/ \ -g http://pkg/ oracle.com/solaris/rekease/solaris
  C. cat so1.repo.iso-a so1.repo.iso-b > so1.full.iso Mount the ISO image and use the rsync command to extract the contents of the ISO file to /export/IPS/repo Set the pkg/inst_root property to /export/IPS/repo and the pkg/readonly property to true Set the preferred publisher by using pkg set-publisher solaris \ -g http://pkg.oracle.com/
  D. cat so1.repo,iso-a so1.repo.iso-b > /export/IPS/repo.iso Mount the ISO image and copy the repo directory from the ISO image to /export/IPS/repo set the pkg/inst_root property and the pkg/readonly property to /export/IPS/repo set the preferred pkg/inst_root property by using pkg set-publisher - G http://serverA.example.com/ \ -g http://pkg.oracle.com/solaris.com/release/- p solaris
  D. cat so1.repo,iso-a so1.repo.iso-b > /export/IPS/repo.iso Mount the ISO image and copy the repo directory from the ISO image to /export/IPS/repo set the pkg/inst_root property and the pkg/readonly property to /export/IPS/repo set the preferred pkg/inst_root property by using pkg set-publisher - G http://serverA.example.com/ \ -g http://pkg.oracle.com/solaris.com/release/- p solaris

  Concatenate the files into one file using the cat command. Make the contents of the repository .iso file available using the mount command. To increase the performance of repository accesses and to avoid the need to remount the .iso image each time the system restarts, copy the repository files from /mnt/repo/to a ZFS file system. You can do this copy with rsync or with tar.

• Question 35:

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

  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 40:

  You are setting up a local IPS package repository on your Oracle Solaris 11 server; solans example.com

  You want to point the existing local IPS publisher to the new local IPS repository located in /repo. These are the steps that you have followed:

  1 Download and rsync the contents of the Oracle Solaris 11 repository ISO image to the /repo directory.

  2. Configure the repository server service properties. The svcprop command displays the IPS-related properties:
