You need to update an OS image on a client. The pkg publishers command displays the wrong publisher with the wrong update:

PUBLISHERTYPESTATUSURI

Solaris origin onlinehttp://pkg.oracle.com/solaris/release

The update is available on the updated publisher: 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.

  1. 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

  2. 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.com

    Refresh the application/pkg/server service.

    Issue the pkgrepo refresh command to repository catalog

  3. 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.

  4. Add the new publisher http://sysA.example.com Solaris

Use the pkg set-publisher command to set the publisher search order and place http://sysA.example.com of http://pkg.oracle.com/solaris/release

Issue the pkg publisher command to view the publishers. Set the new publisher to sticky.

Issue the pkg update command to update the OS image.

Answer: C

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.

Question No: 43

You upgraded your server to Oracle bolans 11 and you imported a zpool(pooll) that was created in bolaris 10. You need to create an encrypted ZFS file system in pooll, but first you need to make sure that your server supports ZFS encryption.

Which four statements are true for support of ZFS encryption?

  1. The encrypted file system must have been created in Oracle Solaris 11. To encrypt a ZFS file system from a previous version of Solaris, upgrade

    the zpool and create a new encrypted ZFS file system in that zpool Finally, move or copy the data from the existing ZFS file system into the new encrypted ZFS file system.

  2. if you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 30, minimum.

  3. ZFS encryption is integrated with the ZFS command set and no additional packages need to be installed.

  4. ZFS encryption requires that the ZFS Dataset Encryption package be installed.

    E If you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 21, minimum. D f Encryption is supported at the pool or dataset (file system) level

  5. Encryption is supported at the pool level only and every file system in the pool will be encrypted.

  6. Encryption is supported at the pool level only and every file system in the pool will be encrypted.

  7. You cannot create an encrypted file system in a zpool that was created prior to Oracle Solaris 11.

Create a new zpool in Solaris 11, create an encrypted ZFS file system in the new zpool, and move or copy the data from the existing file system into the new encrypted file system.
