Oracle Oracle Certifications 1Z0-821 Questions & Answers

• Question 51:

  You are setting up a local IPS package repository on your Oracle Solaris11 server:

  solaris.example.com.

  You want to point the existing local IPS publisher to the new local IPS repository located in /repo.

  These are the stops that you have followed:

  1.

  Download and rsync the contents of the Oracle Solaris11 repository ISO image to the /repo directory.

  2.

  Configure the repository server service properties. The svcprop command display, the IPS related properties:

  pkg/inst_root astring/repo

  pkg/readonly Boolean true

  The 1s command displays the contents of the /repo directory:

  #ls/repo

  Pkg5.repository publisher

  The svcs publisher command shows the svc: /application/pkg/server: default service is online.

  The pkg publisher command shows the svc: /application/pkg/server: default service is online.

  The pkg publisher command still displays:

  PUBLISHERTYPESTATUSURI

  solarisoriginonlinehttp://pkg.oracle.com/solaris/release/

  Which steps needs to be performed to set the local IPS publisher to the local IPS repository/repo?

  A. Issue the pkgrepo refresh -s command to refresh the repository.

  B. Restart the svc:/application/pkg/server:default service.

  C. pkg set-publisher command to set the new repository location.

  D. Issue the pkgrepo rebuild command to rebuild the repository.

  E. Issue the pkgrepo set command to set the new repository location.

  Correct Answer: C

  Set the Publisher Origin To the File Repository URI

  To enable client systems to get packages from your local file repository, you need to reset the origin for the

  solaris publisher. Execute the following command on each client:

  Example:

  # pkg set-publisher -G '*' -M '*' -g /net/host1/export/repoSolaris11/ solaris

• Question 52:

  Which three Installation option allow for a "hands free" and "unattended'" Installation of the Solaris 11 environment?

  A. Jumpstart

  B. LiveCD

  C. A text Installation over the network

  D. An Automated Installation performed on an x86 client

  E. An Automated Installation using media from a local DVD or USB drive

  F. An Automated Installation using a networked repository

  Correct Answer: DEF

  Oracle Solaris 11 uses Automated Installer (AI) for unattended installations.

  Unattended installations are possible by placing the contents of the AI Image media (or ISO image contents from a download) on an AI server.

• Question 53:

  Which statement is correct about shudown and init commands?

  A. shutdown broadcasts one or more periodic shutdown warning messages to all logged-in users whereas init issues none.

  B. The shutdown command performs a clean shutdown of all services whereas init does not.

  C. The shutdown command brings the system to the single-user milestone by default. The init command must be used to shut the system down to run level 0.

  D. The shutdown command accepts SMF milestones, init stages, or run levels as arguments whereas init accepts only init stages or run levels as arguments.

  Correct Answer: A

• Question 54:

  You want to display network interface information. Which command should you use?

  A. ipadm show-if

  B. ipadm show-addr

  C. ipadm show-prop

  D. ipadm show-addrprop

  Correct Answer: A

• Question 55:

  Which two are implemented using the Internet Control Message Protocol (ICMP)?

  A. ping

  B. DHCP

  C. HTTP

  D. telnet

  E. syslog

  F. traceroute

  Correct Answer: AF

  The Internet Control Message Protocol (ICMP) is one of the core protocols of the Internet Protocol Suite. ICMP differs from transport protocols such as TCP and UDP in that it is not typically used to exchange data between systems, nor is it regularly employed by end-user network applications (with the exception of some diagnostic tools like ping and traceroute).

• Question 56:

  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= YESRestart the syslogd daemon.

  C. svcadm enable svc:/system/system -log/config/log_from_remoteRestart the syslogd daemon.

  D. svccfg -s svc:/system/system-log setprop config/log_from_remote=trueRestart the syslogd daemon.

  E. Set the following parameter in the /etc/default/syslogd file: LOG_FROM_REMOTE=YESRestart the syslogd daemon.

  Correct Answer: BD

  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 57:

  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.

  Correct Answer: ABF

  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 58:

  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

  Correct Answer: ABCD

  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 59:

  C: R Indicates the file/directory was renamed in the later dataset

  E: - Indicates the file/directory was removed in the later dataset

  G: M Indicates the file/directory was modified in the later dataset

  Note: Identifying ZFS Snapshot Differences (zfs diff) You can determine ZFS snapshot differences by using the zfs diff command.

  The following table summarizes the file or directory changes that are identified by the zfs diff command.

  File or Directory Change Identifier

  *

  File or directory is modified or file or directory link changed M

  *

  File or directory is present in the older snapshot but not in the newer snapshot -

  *

  File or directory is present in the newer snapshot but not in the older snapshot +

  *

  File or directory is renamed R

• Question 60:

  You have a ticket from a new user on the system, indicating that he cannot log in to his account. The information in the ticket gives you both the username and password. The ticket also shows that the account was set up three days ago.

  As root, you switch users to this account with the following command:

  su ?newuser

  You do not get an error message.

  You then run 1s -1a and see the following files:

  local1.cshrc local1.login local1.profile .bash_history .bashrc .profile

  As root, you grep the /etc/passwd file and the /etc/shadow file for this username, with these results:

  /etc/passwd contains newuser:x:60012:10:/home/newuser:/usr/bin/bash

  /etc/shadow contains newuser:UP: : : : :10: :

  As root, what is your next logical step?

  A. Usermod -f 0

  B. passwd newuser

  C. mkdir /home/newuser

  D. useradd -D

  Correct Answer: B

  The content of the /etc/shadow document indicates that the newuser account has no password. We need to add a password.

  The passwd utility is used to update user's authentication token(s).

  D: Here the user account already exist. There is no need to create it.

  When invoked without the -D option, the useradd command creates a new user account using the values specified on the command line plus the default values from the system. Depending on command line options, the useradd command will update system files and may also create the new user's home directory and copy initial files.
