You have been asked to do an orderly shutdown on a process with a PID of 1234,with the kill command.

Which command is best?

A. kill -2 1234

B. kill -15 1234

  1. kill -9 1234

  2. kill -1 1234

Answer: B Explanation:

On POSIX-compliant platforms,SIGTERM is the signal sent to a process to request its termination. The symbolic constant for SIGTERM is defined in the header file signal.h. Symbolic signal names are used because signal numbers can vary across platforms,however on the vast majority of systems,SIGTERM is signal #15.

SIGTERM is the default signal sent to a process by the kill or killall commands. It causes the termination of a process,but unlike the SIGKILL signal,it can be caught and interpreted (or ignored) by the process. Therefore,SIGTERM is akin to asking a process to terminate nicely,allowing cleanup and closure of files. For this reason,on many Unix systems during shutdown,init issues SIGTERM to all processes that are not essential to powering off,waits a few seconds,and then issues SIGKILL to forcibly terminate any such processes that remain.

Question No: 143 – (Topic 2)

Select the five tasks that need to be performed on the Automated Installer (AI) install server before setting up the client.

  1. Create a local IPS repository on the AI Install server and start the repository server service,the publisher origin to the repository file.

  2. Set up a IP address on the AI install server.

  3. The DHCP server must be enabled on the install server and must provide the DHCP service for the clients.

  4. DHCP must be available on the network for the Install server and the clients,but the install server does not need to be the DHCP server.

  5. Download the AI boot image. The image must be the same version as the Oracle Solaris OS that you plan to install on the client.

  6. Download the text install image into the IPS repository.

  7. Install the AI installation tools.

  8. Create the AI install service. Specify the path to the AI network boot image ISO file and the path where the AI net image ISO file should be unpacked.

  9. Create the AI install service. Specify the path to the AI network boot image ISO file and the path to the IPS repository.

Answer: B,D,F,G,I Explanation:

B: Configure the AI install server to use a static IP address and default route.

D: The create-service command can set up DHCP on the AI install server. If you want to set up a separate DHCP server or configure an existing DHCP server for use with AI. The DHCP server must be able to provide DNS information to the systems to be installed.

E: An automated installation of a client over the network consists of the following high-level steps:

  1. The client system boots over the network and gets its network configuration and the location of the install server from the DHCP server.

  2. The install server provides a boot image to the client.

  3. Characteristics of the client determine which installation instructions and which system configuration instructions are used to install the client.

  4. The Oracle Solaris 11 OS is installed on the client,pulling packages from the package repository specified by the installation instructions in the AI install service.

    G: Install the AI tool set.

    Use the installadm create-service command to create an AI install service. Give the service a meaningful name,and specify the path where you want the service created. Specify the source of the network boot image (net image) package or ISO file.

    installadm create-service [-n svcname] [-s FMRI_or_ISO] [-d imagepath]

    -d imagepath

    The imagepath is the location of the new install service. The install-image/solaris-auto- install package is installed to this location,or the specified ISO file is expanded at this location.

    Question No: 144 – (Topic 2)

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

    1. /var/adm/authlog

    2. /etc/syslog.conf

    3. /etc/default/login

    4. /var/adm/loginlog

      Answer: A,B,C Explanation:

      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 No: 145 – (Topic 2)

        You need to install the gzip software package on your system. Which command would you use to find the software package in the configured repository?

        1. pkg search gzip

        2. pkg info gzip

        3. pkg contents gzip

        4. pkginfo gzip

        5. yum list gzip

Answer: A Explanation:

Use the pkg search command to search for packages whose data matches the specified pattern.

Like the pkg contents command,the pkg search command examines the contents of packages. While the pkg contents command returns the contents,the pkg search command

returns the names of packages that match the query.

Question No: 146 – (Topic 2)

When setting up Automated Installer (AI) clients,an interactive tool can be used to generate a custom system configuration profile. The profile will specify the time zone,data and time,user and root accounts,and name services used for an AI client installation. This interactive tool will prompt you to enter the client information and an SC profile (XML) will be created.

Which interactive tool can be used to generate this question configuration?

  1. sys-unconfig

  2. installadm set-criteria

  3. sysconfig create-profile

  4. installadm create-profile

Answer: B Explanation:

Use the installadm set-criteria command to update the client criteria associated with an AI manifest that you already added to a service using installadm add-manifest.

Use the installadm add-manifest command to add a custom AI manifest to an install service.

The value of manifest is a full path and file name with .xml extension. The manifest file contains an AI manifest (installation instructions). The manifest file can also reference or embed an SC manifest (system configuration instructions).

Question No: 147 – (Topic 2)

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?

  1. Verify the contents of /etc/resolve.conf.

  2. Run netstat -nr to verify the routing to the DNS server.

  3. Ping the IP address of the IPS server to verify connectivity.

  4. On the installation server,verify that the menu.1st file for the client points to a valid boot arc hive.

  5. Run df -k to verify that the boot directory containing the boot archive is loopback mounted under /etc/netboot.

  6. Run the command /sbin/dhcpinfo DNSserv to ensure that the DHCP server providing the DNS server information.

Answer: A,B,F Explanation: 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 No: 148 – (Topic 2)

    The crash dump notification on your server is:

    Ensurepass 2018 PDF and VCE

    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?

    1. savecore -f vmdump.0

    2. dumpadm uncompressed

    3. gunzip vmdump.0

    4. dumpadm -z off

    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#39;s

    current dump device. This option may be use- ful if the information stored on the dump device has been copied to an on-disk file by means of the dd(1M) command.

    Question No: 149 – (Topic 2)

    2. dladm show-dev

    3. dladm show-phys

    4. dladm show-ether

    5. netadm show-dev

    6. netadm show-ether

    Answer: B Explanation: dladm show-dev

    Shows information for all devices or the specified device.

    Question No: 150 – (Topic 2)

    You have a process called bigscript,and you need to know the PID number for this process. Which command will provide that information?

    1. pkill bigscript

    2. ps bigscript

    3. pgrep bigscript

    4. prstat bigscript

    Answer: C Explanation:

    Pgrep takes a process name and return a PID.

    Note: pgrep looks through the currently running processes and lists the process IDs which matches the selection criteria to stdout. All the criteria have to match. For example,

    pgrep -u root sshdwill only list the processes called sshd AND owned by root.

    Incorrec answers:

    ps bigscript: You can’t pass a name to ps,it interprets it as arguments.
