Which five statements describe options available for installing the Oracle Solaris 11operating system using the installation media?
- A. The GUI installer cannot be used to upgrade your operating system from Solaris 10.
- B. The LiveCD Installation cannot be used to install multiple instances of Oracle Solaris.

- D. If you are installing Oracle Solaris 11 on an x86-based system that will have more than one operating system installed in it,you cannot partition your disk during the installation process.
- E. The LiveCD installer cannot be used if you need to preserve a specific Solaris Volume Table of Contents (VTOC) slice in your current operating system.
- F. The text Installer does not install the GNOME desktop. The GNOME desktop package must he added after you have installed the operating system.
- G. The LiveCD Installer is for x86 platforms only.
- H. You can perform a text or LiveCD installation locally or over the network.
Answer: A,C,E,F,H

F: How do I upgrade my Solaris 10 or lower systems to Solaris 11?
Unfortunately,you CAN'T. There is no direct upgrade installer or other tool that will allow you to upgrade from earlier releases of Solaris to Solaris 11. This is primarily due to the vast changes in the packaging mechanism in Solaris 10.

NEW QUESTION # 31
A local repository is available on this system and you need to enable clients to access this repository via HTTP. The repository information is:
PUBLISHERTYPESTATUSURI
solarisoriginonlinehttp://sysA.example.com
Identify two of the steps that are required to make the local repository on this server available to the client via HTTP.
- A. On the client: set the pkg/inst_root and pkg/readonly properties for the svc:/application/server:default service enable the service.
- B. On the client: start the pkg.depotd process.
- C. On the server: set the pkg/inst_root and pkg/readonly properties for the svc:/application/pkg/server:default service and enabled the service
- D. On the server: set the sharefs property on the ZFS file system containing the IPS repository.
- E. On the client: reset the origin for the solaris publisher.
Answer: B,C

To enable clients to access the local repository via HTTP, enable the application/pkg/server Service Management Facility (SMF) service.
# svccfg -s application/pkg/server setprop pkg/inst_root=/export/repoSolaris11
# svccfg -s application/pkg/server setprop pkg/readonly=true
E: Use pkg.depotd to serve the repository to clients.
Start the Repository Service
Restart the pkg.depotd repository service.
# svcadm refresh application/pkg/server
# svcadm enable application/pkg/server
To check whether the repository server is working, open a browser window on the localhost location.
NEW QUESTION # 32

NEW QUESTION # 33
When you issue the "gzip: zommand not found" message is displayed. You need to install the gzip utility on your system.
Which command would you use to check if the gzip utility is available from the default publisher for installation?
- A. pkg list SUNWgzip
- B. pkg info|grep gzip
- C. pkg search gzip
- D. pkg contents gzip
Answer: C
Explanation:
Searching for Packages
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.
pkg search
search [-HIaflpr] [-o attribute ...] [-s repo_uri] query
Search for matches to the query, and display the results.
Which tokens are indexed are action-dependent, but may include content hashes and pathnames.
Note: pkg is the retrieval client for the image packaging system. With a valid configuration, pkg can be invoked to create locations for packages to be installed, called 'images', and install packages into those images.
Packages are published by publishers, who may make their packages available at one or more repositories.
pkg, then, retrieves packages from a publisher's repository and installs them into an image.
NEW QUESTION # 34
You have a user that needs to use the cron tool to schedule some repetitive tasks. When the user enters the crontab -e command in a terminal window, the following error appears:
crontab: you are not authorized to use cron. Sorry
In order to troubleshoot this issue, in what directory would you start your invest
- A. /var/spool/cron/crontable
- B. /var/spool/cron/atjobs
- C. /var/spool/cron
- D. /etc/cron.d
Answer: D
Explanation:
crontab: you are not authorized to use cron. Sorry.
This message means that either the user is not listed in the cron.allow file (if the file exists), or the user is listed in the cron.deny file.
You can control access to the crontab command by using two files in the /etc/cron.d directory: cron.deny and cron.allow. These files permit only specified users to perform crontab command tasks such as creating, editing, displaying, or removing their own crontab files.
The cron.deny and cron.allow files consist of a list of user names, one user name per line.
NEW QUESTION # 35
You run the command dlstat show-link -r.
Select the two correct statements regarding the information displayed in the INTRS column.
- A. A number equal to the number of transmitted Ethernet frames is listed for physical links.
- B. The number of packets that were interrupted by a collision is listed, which may indicate hardware problems.
- C. A value of 0 is listed for virtual interfaces and ether stubs.
- D. No value is listed for virtual network interfaces.
- E. The number of Interrupts is listed, which indicates network efficiency.
Answer: B,E
Explanation:
In this output, the statistics for interrupt (INTRS) are significant. Low interrupt numbers indicate greater efficiency in performance. If the interrupt numbers are high, then you might need to add more resources to the specific link.
Example: # dlstat -r -i 1 LINK IPKTS RBYTES INTRS POLLS CH<10 CH10-50 CH>50 e1000g0 101.91K 32.86M 87.56K 14.35K 3.70K 205 5 nxge1 9.61M 14.47G 5.79M 3.82M 379.98K 85.66K 1.64K

Explanation/Reference:
Explanation:
A: Conditional and system locations can be manually activated, which means that the location remains active until explicitly disabled.
D: A location comprises certain elements of a network configuration, for example a name service and firewall settings, that are applied together, when required. You can create multiple locations for various uses. For example, one location can be used when you are connected at the office by using the company intranet. Another location can be used at home when you are connected to the public Internet by using a wireless access point. Locations can be activated manually or automatically, according to environmental conditions, such as the IP address that is obtained by a network connection.

PUBLISHERTYPESTATUSURI
Solaris originonlinehttp://sysA.example.com
Select the option that describes the procedure used to update the OS image on the system from the updated publisher.
- A. Configure the publisher on the client using the svcfg - s command so that the Solaris publisher is connected to the repository at http://sysA.example.comRefresh the application/pkg/server service. Issue the pkgrepo refresh command to repository catalog
- B. Add the new publisher http://sysA.example.com SolarisUse the pkg set-publisher command to set the publisher search order and place http://sysA.example.com of
http://pkg.oracle.com/solaris/releaseIssue the pkg publisher command to view the publishers. Set the new publisher to sticky. Issue the pkg update command to update the OS image. - C. Copy the repository from the ISO image onto the local client. Configure the repository on the client by using the svccfg - s command so that the Solaris publisher is connected to the new repository. Refresh the application/pkg/server service. Issue the pkgrepo refresh command to refresh the repository catalog
- D. Use the pkg set-publisher command to change the URL of the publisher Solaris to
http://sysA.example.com. Issue the pkg update command to update the OS image.
Answer: D
Explanation:
You can use the pkg set-publisher command to change a publisher URI.
Changing a Publisher Origin URI
To change the origin URI for a publisher, add the new URI and remove the old URI. Use the -g option to add a new origin URI. Use the -G option to remove the old origin URI.
# pkg set-publisher -g http://pkg.example.com/support \
-G http://pkg.example.com/release example.com
Note: You can use either the install or update subcommand to update a package.
The install subcommand installs the package if the package is not already installed in the image. If you want to be sure to update only packages that are already installed, and not install any new packages, then use the update subcommand.
