• Question 232:

  A change in your company's security policy now requires an audit trial of all administrators assuming the sysadm role, capturing:

  There are two command necessary to accomplish this change. One is a rolemod command. What is the other?

  A. auditconfig set policy=argv
  B. auditconfig -setpolicy +argv
  C. auditconfig -setflags lo, ex sysadm
  D. auditconfig set flags=lo, ex sysadm
  B. auditconfig -setpolicy +argv

  ---

  Audit Significant Events in Addition to Login/Logout (see step 2 below) Use this procedure to audit administrative commands, attempts to invade the system, and other significant events as specified by your site security policy.

  For all users and roles, add the AUE_PFEXEC audit event to their preselection mask.

  # usermod -K audit_flags=lo, ps:no username # rolemod -K audit_flags=lo, ps:no rolename # auditconfig -setpolicy +argv 3- Record the environment in which audited commands are executed. # auditconfig -setpolicy +arge

  Note: [-t] -setpolicy [+|-]policy_flag[, policy_flag ...] Set the kernel audit policy. A policy policy_flag is literal strings that denotes an audit policy. A prefix of + adds the policies specified to the current audit policies. A prefix of - removes the policies specified from the current audit policies. No policies can be set from a local zone unless the perzone policy is first set from the global zone.

• Question 233:

  Which three files must be edited in order to set up logging of all failed login attempts?

  A. /var/adm/authlog
  B. /etc/syslog.conf
  C. /etc/default/login
  D. /var/adm/loginlog
  A. /var/adm/authlog
  B. /etc/syslog.conf
  C. /etc/default/login

  ---

  How to Monitor All Failed Login Attempts

  This procedure captures in a syslog file all failed login attempts.

  Assume the Primary Administrator role, or become superuser.

  1.

  Assume the Primary Administrator role, or become superuser.

  2.

  (C) Set up the /etc/default/login file with the desired values for SYSLOG and SYSLOG_FAILED_LOGINS

  3.

  (A) Create a file with the correct permissions to hold the logging information. Create the authlog file in the /var/adm directory.

  4.

  (B) Edit the syslog.conf file to log failed password attempts.

• Question 234:

  Which command would you use from the bash shell to determine the total amount of physical memory installed in your Solaris system (x86 and SPARC)?

  A. uname -a
  B. prtconf | grep -i memory
  C. sysdef | grep -i memory
  D. vmstat
  E. prtdiag | grep -i memory
  B. prtconf | grep -i memory

  ---

  The prtconf command prints the system configuration information. The output includes the total amount of memory, and the configuration of system peripherals formatted as a device tree.

  If a device path is specified on the command line for those command options that can take a device path, prtconf will only display information for that device node.

• Question 235:

  Which command should you choose to display the current parameters for the FSS scheduler?

  A. dispadmin - c FSS
  B. prionctl -c FSS
  C. dispadmin -c FSS -g
  D. priocntl -c FSS -g
  C. dispadmin -c FSS -g

  ---

  The dispadmin command displays or changes process scheduler parameters while the system is running.

  -c class

  Specifies the class whose parameters are to be displayed or changed. Valid class values are: RT for the real-time class, TS for the time-sharing class, IA for the inter-active class, FSS for the fair-share class, and FX for the fixed-priority class.

  The time-sharing and inter- active classes share the same scheduler, so changes to the scheduling parameters of one will change those of the other.

  -g

  Gets the parameters for the specified class and writes them to the standard output.

• Question 236:

  The OpenBoot firmware controls the operation of the system before the operating system is loaded.

  Which four tasks are directly controlled by the OpenBoot firmware?

  A. Provides a list of boot entries from which to choose
  B. Allows hardware to identify itself and load its own plug-in device driver
  C. Loads the boot loader from the configured boot device
  D. Performs basic hardware testing
  E. Installs the console
  F. Reads and executes the boot archive
  G. Extract and executes the kernel image
  A. Provides a list of boot entries from which to choose
  B. Allows hardware to identify itself and load its own plug-in device driver
  C. Loads the boot loader from the configured boot device
  D. Performs basic hardware testing

  ---

  OpenBoot firmware is executed immediately after you turn on your system. The primary tasks of OpenBoot firmware are to:

  *

  Test and initialize the system hardware (D)

  *

  Determine the hardware configuration (D)

  *Boot the operating system from either a mass storage device or from a network *Provide interactive debugging facilities for testing hardware and software Some notable features of OpenBoot firmware.

  *

  Plug-in Device Drivers (B)

  Most common tasks that you perform using OpenBoot

  *

  Booting Your System The most important function of OpenBoot firmware is to boot the system. Note: If auto-boot? is true, the system will boot from either the default boot device or from the diagnostic boot device depending on whether OpenBoot is in diagnostic mode. (C)

• Question 237:

  B. The manual network configuration option was chosen during the installation of the OS.
  C. The network was not configured during the installation of the OS.
  D. The network interface is configured with a static IP address.
  C. The network was not configured during the installation of the OS.

• Question 238:

  You suspect a problem with the oponldap package and want to make sure that the files have not be modified or otherwise tampered with.

  Which command would validate all of the files contained in the openldap package and report any problems?

  A. pkgchk openldap
  B. pkginfo openldap
  C. pkg contents openldap
  D. pkg verify openldap
  E. pkg set-property signature-policy verify
  A. pkgchk openldap

  ---

  pkgchk checks the accuracy of installed files or, by using the -l option, displays information about package files. pkgchk checks the integrity of directory structures and files. Discrepancies are written to standard error along with a detailed explanation of the problem.

• Question 239:

  You have connected a new printer at a fixed IP address.

  It appears to work correctly most of the time, but at other times does not respond.

  You suspect that the assigned address may not be unique within the network.

  What command will be useful to confirm this?

  A. arp
  B. netstat
  C. ipadm show-if
  D. dladm show-addr
  E. ipadm show-addr
  E. ipadm show-addr

  ---

  'ipadm show-addr' displays all the configured addresses on the system.

  Example: # ipadm show-addr ADDROBJ TYPE STATE ADDR lo0/v4 static ok 127.0.0.1/8 lo0/v6 static ok ::1/128

• Question 240:

  Review the information taken from your server:

  

  Which option describes the command used to create these snapshots of the root file system?

  zfs snapshot [-r] [-o property=value] ... filesystem@snapname|volume@snapname Creates a snapshot with the given name. All previous modifications by successful system calls to the file system are part of the snapshot. See the

  "Snapshots" section for details.

  -r

  Recursively create snapshots of all descendent datasets. Snapshots are taken atomically, so that all recursive snapshots correspond to the same moment in time.
