Oracle Oracle Certifications 1Z0-821 Questions & Answers

• Question 61:

  You display the IP interface information with ipmpstat -i.

  Which two characteristics are indicated by characters that may be included in the FLAGS column?

  A. default route

  B. IP forwarding enabled IS

  C. allocated to global zone

  D. unusable due to being inactive

  E. nominated to send/receive IPv4 multicast for its IPMP group

  Correct Answer: DE

  FLAGS

  Indicates the status of each underlying interface, which can be one or any combination of the following:

  (D)

  d indicates that the interface is down and therefore unusable.

  (E)

  M indicates that the interface is designated by the system to send and receive IPv6 multicast traffic for the IPMP group.

  Note:

  i indicates that the INACTIVE flag is set for the interface. Therefore, the interface is not used to send or

  receive data traffic.

  s indicates that the interface is configured to be a standby interface.

  m indicates that the interface is designated by the system to send and receive IPv4 multicast traffic for the

  IPMP group.

  b indicates that the interface is designated by the system to receive broadcast traffic for the IPMP group.

  h indicates that the interface shares a duplicate physical hardware address with another interface and has

  been taken offline. The h flag indicates that the interface is unusable.

• Question 63:

  Choose three options that describe the features associated with a Live Media installation.

  A. does not allow the root user to log in to the system directly from the console (or any terminal)

  B. provides a "hands free" installation

  C. installs the desktop based packages

  D. can be used to install only x86 platforms

  E. installs the server-based set of packages only

  F. allows both automatic and manual configuration of the network

  G. installs both the server-based and desktop-based package

  Correct Answer: BCD

  The graphical installer is officially known as the "Live Media." This means that Oracle Solaris can be booted into RAM, causing zero impact on your existing operating system. After it is loaded, you are free to experiment with Oracle Solaris to determine whether it is something you would like to install to your system.

  You can download Oracle Solaris 11 Live Media for x86, which is an approximately 800 MB image file, and use a DVD burner to create the disk, or you can use the ISO image directly in a virtual machine or through the Oracle Integrated Lights Out Manager (ILOM) Remote Console.

  The Live Media is not intended for long-term use. For example, any changes that you make to the system are lost when the system is shut down. Therefore, the next logical step is to install Oracle Solaris on the system, which the Live Media makes easy by placing an Install Oracle Solaris icon right on the desktop. But before we head down that road, let's step back a bit and consider the installation options.

  Note: The Live Media provides administrators with an opportunity to explore the Oracle Solaris 11 environment without installing it on a system. The system boots off the media directly allowing administrators to start the installer should they choose to install it to a system.

• Question 64:

  Consider the following commands:

  

  What is displayed when this sequence of commands is executed using the bash shell?

  A. Hello, world

  B. cat: cannot open file1: No such file or directory Hello, world

  C. cat: cannot open file1: No such file or directory

  D. bash: syntax error near unexpected token '| |'

  E. bash: syntax error broker pipe

  Correct Answer: B

• Question 65:

  You are logged in to a Solaris 11 system as user jack. You issue the following sequence of commands: Identify two correct statements.

  

  A. You have the effective privilege of the account root.

  B. Your GID is 10.

  C. Your home directory is /root.

  D. You are running the shell specified for the account root.

  E. Your UID is 1.

  Correct Answer: AB

  Oracle Solaris provides predefined rights profiles. These profiles, listed in the /etc/security/prof_attr, can be assigned by the root role to any account. The root role is assigned all privileges and all authorizations, so can perform all tasks, just as root can when root is a user.

  To perform administrative functions, you open a terminal and switch the user to root. In that terminal, you can then perform all administrative functions.

  $ su - root Password: Type root password # When you exit the shell, root capabilities are no longer in effect.

• Question 66:

  Your SPARC server will not boot into multi user-server milestones and you need to troubleshoot to out why. You need to start the server with minimal services running so that you can go through each milestone manually to troubleshoot the issue.

  Select the option that boots the server with the fewest services running.

  A. boot -s

  B. boot milestone none

  C. boot -m milestone=single-user

  D. boot -m milestone=none

  E. boot -m none

  Correct Answer: D

  The command boot -m milestone=none is useful in repairing a system that have problems booting early.

  Boot Troubleshooting: To step through the SMF portion of the boot process, start with: boot -m milestone=none Then step through the milestones for the different boot levels: svcadm milestone svc:/milestone/single-user:default svcadm milestone svc:/milestone/multi-user:default svcadm milestone svc:/milestone/multi-user-server:default

• Question 67:

  United States of America export laws include restrictions on cryptography.

  Identify the two methods with which these restrictions are accommodated in the Oracle Solaris 11 Cryptographic Framework.

  A. Corporations must utilize signed X.509 v3 certificates.

  B. A third-party provider object must be signed with a certificate issued by Oracle.

  C. Loadable kernel software modules must register using the Cryptographic Framework SPI.

  D. Third-party providers must utilize X.509 v3 certificates signed by trusted Root Certification Authorities.

  E. Systems destined for embargoed countries utilize loadable kernel software modules that restrict encryption to 64 bit keys.

  Correct Answer: BC

  B: Binary Signatures for Third-Party Software The elfsign command provides a means to sign providers to be used with the Oracle Solaris Cryptographic Framework. Typically, this command is run by the developer of a provider.

  The elfsign command has subcommands to request a certificate from Sun and to sign binaries. Another subcommand verifies the signature. Unsigned binaries cannot be used by the Oracle Solaris Cryptographic Framework. To sign one or more providers requires the certificate from Sun and the private key that was used to request the certificate.

  C: Export law in the United States requires that the use of open cryptographic interfaces be restricted. The Oracle Solaris Cryptographic Framework satisfies the current law by requiring that kernel cryptographic providers and PKCS #11 cryptographic providers be signed.

• Question 68:

  You are creating a non-global zone on your system.

  Which option assigns a zpool to a non-global zone, and gives the zone administrator permission to create zfs file system in that zpool?

  A. While creating the non-global zone, make the following entry: add deviceset match=/dev/rdsk/ c4t0d0endBoot the zone and log in the zone as root. Create the zpool: zpool create pool2 c4t0d0In the non-global zone, root can now create ZFS file system in the pool2 zpool

  B. In the global zone, create the zpool: global# zpool create pool2 c4t1d0While creating the no-global zone, make the following entry: add datasetset name=pool2endadd fsset dir=pool1set special=pool1set type=zfspool1endBoot the zone, log in the zone as root, and create the zfs file system in the pool2 zpool.

  C. In the global zone, create the zpool:global#zpool create pool2 c4t1d0While creating the global zone, make the following entry: add datasetset name=pool2endBoot the zone, log in to the zone as root and create the zfs file systems in the pool2 zpool.

  D. In the global zone, create the zpool and the ZFS file systems that you want to use in the non-global zone: global#zpool create pool2 c4t1d0global#zfs create pool2/dataWhile creating the non-global zone, make the following entry for each ZFS file system that you want to make available in the zone: add fsset dir=/dataset special=pool2/dataset type=zfsend

  E. Create the zpool in the global zone: global#zpool create pool2 c4t1d0Boot the non- global zone, log in to the zone as root, and issue this command to delegate ZFS permissions to root: non-global zone# zfs allow root create , destroy, mount pool2Log in to the non-global zone create ZFS file systems in the pool2 zpool.

• Question 69:

  You are currently working in both your home directory and the system directory /tmp. You are switch back and forth with full path names. Which pair of cd commands will provide you with a shortcut to switch between these two locations?

  A. cd ~ and cd

  B. cd and cd.

  C. cd ~ and cd

  D. cd * and cd . .

  Correct Answer: A

  In the Bourne Again, C, Korn, TC, and Z shells, the tilde (~) is used as a shortcut for specifying your home

  directory.

  cd It's the command-line equivalent of the back button (takes you to the previous directory you were in).

  Note:

  To make certain that you are in your home directory, type the cd (change directory) command. This

  command moves you to your home (default) directory.
