NEW QUESTION 85
Which two options accurately describe the network characteristics of a zone?

  • A. Exclusive IP is the defaulttype of network configuration.
  • B. By default, all IP addresses, netmasks, and routes are set by the global zone and cannot be altered in a non global zone.
  • C. Shared IP is the default type of network configuration.
  • D. Commands such as snoop and dladm cannot be used on datalinks that are in use by a runningzone.
  • E. IPMP cannotbe managed within the non-global zone.
  • F. DHCP address assignment cannot be configured in a shared IP zone.

Answer: C,F

Explanation:
A: Non-global zones can not utilize DHCP (neither client nor server). B(not C):By default, non-global zones will be configured with a shared IP functionality. What this means is that IP layer configuration and state is shared between the zone you're creating and the global zone. This usually implies both zones being on the same IP subnet for each given NIC.
Note: A zone is a virtual operating system abstraction that provides a protected environment in which applications run. The applications are protected from each other to provide software faultisolation. To ease the labor of managing multiple applications and their environments, they coexist within one operating system instance, and are usually managed as one entity.
The original operating environment, before any zones are created, is also called the "global zone" to distinguish it from non-global zones, The global zone is the operating system instance.
Incorrect answer:
E: Exclusive-IP zones can use IPMP. IPMP is configured the same way in an exclusive-IP zone as
it is on a system not using zones.
For shared-IP zones, IPMP can be configured in the global zone.
F: Full IP-level functionality is available in an exclusive-IP zone.
An exclusive-IP zone has its own IP-related state.
An exclusive-IP zone is assigned its own set of data-links using the zonecfg command. The zone
is given a data-link name such as xge0, e1000g1, or bge32001, using the physical property of the
net resource. The address property of the net resource is not set.
Note that the assigned data-link enables the snoop command to be used.
The dladm command can be used with the show-linkprop subcommand to show the assignment of data-links to running exclusive-IP zones.

NEW QUESTION 86
Choose three options that describe the features associated with a Live Media installation.

  • A. provides a "hands free" installation
  • B. does not allow the root user to log in to the system directly from the console (or any terminal)
  • C. can be used to install only x86 platforms
  • D. installs both the server-based and desktop-based package
  • E. allows both automatic and manual configuration of the network
  • F. installs the server-based set of packages only
  • G. installs the desktop based packages

Answer: A,C,G

Explanation:
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 righton 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.

 

NEW QUESTION 87
Which two are implemented using the Internet Control Message Protocol (ICMP)?

  • A. telnet
  • B. ping
  • C. syslog
  • D. DHCP
  • E. HTTP
  • F. traceroute

Answer: B,F

Explanation:
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).

  • D. ipadm up-addr net3/v4
  • E. <ipadm create-vnic -a 192.168.1.25/24 net3/v4

Answer: C

Explanation:
Explanation/Reference:
Explanation:
If you are assigning a static IP address, use the following syntax:
# ipadm create-addr -T static -a address addrobj
where addrobj uses the naming format interface/user-defined-string, such as e1000g0/v4globalz.
Note:
create-addr [-t] -T static [-d] -a {local | remote}=addr[/prefixlen], ... addrobj Creates a static IPv4 or IPv6 address on the interface specified in addrobj. If the interface on which the address is created is not plumbed, this subcommand will implicitly plumb the interface. The created static address will be identified by addrobj.
By default, a configured address will be marked up, so that it can be used as a source or destination of or for outbound and inbound packets.

 

NEW QUESTION 92
You are using AI to install a new system. You have added to following information to the AI manifest:
<configuration type= "zone" name= "dbzone"
source = "http://sysA.example.com/zone_cfg/zone.cfg"/>
Which statement is true with regard to the zone.cfg?

  • A. The zone.cfg file is an xml file in a form suitable for use as a command file for the zonecfg command.
  • B. The zone.cfg file is text file in a zonecfg export format.
  • C. The zone.cfg file is an SC profile with keywords that are specific for configuring a as part of the installation process.
  • D. It is am xml configuration file from the /etc/zone directory. It will be used as a profile for the zone. It specifies the zonename, zonepath, and other zonecfg parameters.
  • E. The zone.cfg file is an AI manifest that specifies how the zone is to be installed.

Answer: E

Explanation:
The configuration element supports non-global zone configurations. When installing
a global zone system, the zone configurations specified in the AI manifest are used to install non-
global zones onto the system after the global zone has been installed
The configuration element has the following attributes:
type
The type of configuration to install. The only type supported by AI is zone.
name
A name given to the configuration. This name must be unique across all configuration elements in
an AI manifest. For configurations of type zone, this name is also used as the zonename for he
zone.
Source
The location from which AI downloads the configuration file for this configuration element. The
value can be an HTTP or FILE URI specification. For configurations of type zone, this value should
point to a zone configuration file as produced from the zonecfg export command.

 

NEW QUESTION 93
Identify the two security features incorporated in the Oracle Solaris 11 Cryptographic Framework.

  • A. Kernel support for signed antivirus plugins
  • B. Layer 5 IP address encryptions
  • C. Signed cryptographic plugins (providers)
  • D. Internet protocol security
  • E. Diffie-Kerberos coaxial key encryption

Answer: A,C

Explanation:
The framework enables providers of cryptographic services to have their services used by many consumers in the Oracle Solaris operating system. Another name for providers is plugins. The framework allows three types of plugins:
*User-level plugins - Shared objects that provide services by using PKCS #11 libraries, such as pkcs11_softtoken.so.1.
*Kernel-level plugins - Kernel modules that provide implementations of cryptographic algorithms in software, such as AES.
*Hardware plugins - Device drivers and their associated hardware accelerators. The Niagara chips, the ncp and n2cp device drivers, are one example. A hardware accelerator offloads expensive cryptographic functions from the operating system. The Sun Crypto Accelerator 6000 board is one example.
Many of the algorithms in the framework are optimized for x86 with the SSE2 instruction set and for SPARC hardware.

NEW QUESTION 94
On server A, you enter the following command to add a static route to serverA route -p add -host
192.168.1.101 192.168.1.101 -static
What is the purpose of this command?

  • A. to ensure the IP address for serverB is not flushed from the ARP cache
  • B. to specify an IPMP target IP address to in.mpathd
  • C. to specify routing to an adjacent network when in.rdisc is not used
  • D. to specify routing to an adjacent network when in.routed is not used
  • E. to optimize link aggregation using a direct connection between two systems
  • F. to temporarily bypass IP Filter rules

Answer: B

Explanation:
Explanation/Reference:
Explanation:
Note: # route -p add -host destination-IP gateway-IP -static
where destination-IP and gateway-IP are IPv4 addresses of the host to be used as a target.
For example, you would type the following to specify the target system 192.168.10.137, which is on the same subnet as the interfaces in IPMP group itops0:
$ route -p add -host 192.168.10.137 192.168.10.137 -static
This new route will be automatically configured every time the system is restarted. If you want to define only a temporary route to a target system for probe-based failure detection, then do not use the -p option.

 

NEW QUESTION 95
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. useradd -D
  • B. Usermod -f 0
  • C. passwd newuser
  • D. mkdir /home/newuser

Answer: C

Explanation:
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.

NEW QUESTION 96
How are operating system updates distributed in the Oracle Solaris 11 environment?

  • A. Patches are download from http: //support.oracle.comeither automatically or manually. All software packages are then updated manually from the command line using the smpatch orpatchadd commands.
  • B. Software updates, published as packages to an OS image. All software packages are then updatedmanually from the command line using the pkg command.
  • C. Updates are only available to customers with an active support contract. The updates aredistributed through the My Oracle Support web portal and installed in a central location. Allsoftware packages are then updated manually from the command line using the smpatchcommand.
  • D. Software updates are publishedas packages to a repository. Allsoftware packages arethenupdated manually from the command line using the pkg command.

Answer: D

Explanation:
* Updating all of the packages on your installed system - To update all of the packages on your system that have available updates, use the pkg update command, as follows:
# pkg update Running this command updates packages that you might not otherwise consider updating, for example, kernel components and other low-level system packages.
*Adding or updating individual packages - To add individual software packages, use the pkg install command. Any dependent packages are also updated at the same time.
*install package updates that deliver fixes- A pkg update operation might include bug fixes, so the operation is similar to applying a specific patch or patches in previous Oracle Solaris releases.
Note: The IPS interfaces first check for updates for currently installed packages before retrieving them via the network. By default, interfaces check repository catalogs in the following locations:
*The default installation repository at pkg.oracle.com/solaris/release.
*The support repository in My Oracle Support. This repository is restricted to users with Oracle Solaris 11 Express support contracts, and it contains packages with the latest bug fixes. For this reason, a support contract must be purchased for production deployments.
