Your mentor suggests using the dladm rename-link command to rename the network datalinks.

What are the two advantages of following this advice?

  1. It can clarify which network interface has what purpose.

  2. It can simplify specifying the network interface with the dladm modify-aggr command.

  3. It can simplify specifying the network interface with the dladm modify-bridge command.

  4. It can simplify IP filter rule changes if the network interface is replaced with a different type.

  5. It can prevent accidental deletion of the network interface with the dladm delete-phys

    command.

  6. It can prevent accidental deletion of the network interface configuration with the ipadm delete-addr command.

Answer: A,E

Explanation: A: To rename the bge0 link to mgmt0, enter the following command:

# dladm rename-link bge0 mgmt0

E: Consider that the bge0 device, whose link was named mgmt0 as shown in the previous example, needs to be replaced with a ce0 device because of a hardware failure. The bge0 NIC is physically removed, and replaced with a new ce0 NIC. To associate the newly added ce0 device with the mgmt0 configuration previously associated with bge0, enter the following command:

# dladm rename-link ce0 mgmt0 Note: How to Rename a Datalink

Use this procedure if you want to change a datalink name to a customized name. For example, some of the datalinks in upgraded system might have retained legacy hardware- based names and you want to change these names to generic ones.

Note: dladm rename-link [-R root-dir] link new-link

Rename link to new-link. This is used to give a link a meaningful name, or to associate existing link configuration such as link properties of a removed device with a new device.

Question No: 63

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

PUBLISHERTYPESTATUSURI

solansohQinonlinehttp://DkQ.oracle.conVsolaris/release The update is available on this updated publisher: PUBLISHERTYPESTATUSURI

solarisoriQJnonlinehttp://svsA.example.com

Select the option that describes the procedure used to update the OS image on this 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 svccfg -s command so that the solans publisher is connected to the repository at http://svsA.example.com. Refresh the application/pkg/server service. Issue the pkgrepo refresh command to refresh the repository catalog

  3. Use the pkg set-publisher command lo change the URL of the publisher solans to htto://svsA example.com. Issue the pkg update command to update the OS Image.

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

Use the pkg set-publisher command to set the publisher search order and place http://svsA example com ahead 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-

    Use the pkg remove command to remove the gzip package from the current boot environment.

  3. Use the luucreate command to create a new boot environment.

    Use the pkgrm command to remove the gzip package from the current boot environment

  4. Use the pkg unmstall command with the -backup-be-name option

Answer: B

Question No: 66

You are going to create live zones on you server. Disk space is critical on this server so you need to reduce the amount of disk space required for these zones. Much of the data required for each of these zones is identical, so you want to eliminate the duplicate copies of data and store only data that is unique to each zone.

Which two options provide a solution for eliminating the duplicate copies of data that is common between all of these zones?

  1. Create the zones by using sparse root zones.

  2. Set the dedup property to on and the dedupratio to at least 1.5 for the zpool. Create a separate ZFS file system for each zone in the zpool.

  3. Put all of the zones in the same ZFS file system and set the dedupratio property for the ZFS file system to at least 1.5.

  4. Put all of the zones in the same ZFS file system and set the dedup property for the file system to on.

  5. Put each zone in a separate ZFS file system within the same zpool. Set the dedup property to on for each ZFS file system.

Answer: D,E

Explanation: n Oracle Solaris 11, you can use the deduplication (dedup) property to remove redundant data from your ZFS file systems. If a file system has the dedup property enabled, duplicate data blocks are removed synchronously. The result is that only unique data is stored, and common components are shared between files.

Question No: 67

ServerA contains two ISO images of a package repository named so1.repo.iso-a and so1.repo.iso-b respectively. You need to create a single local package repository on server that clients can connect to. The package repository will be stored on the /export/IPS file system and named repo. The preferred publisher will be named solaris and the publisher URL will be http://serverA.example.com.

Which is the correct procedure to perform on ServerA to create the local Package repository?

  1. cat so1.repo.iso-a sol.repo.iso-b gt; so1.full.iso

    Mount the ISO image and use the rsync command to extract the contents of the ISO file to the /export/IPS file system.

    Set the pkg/inst_root property to /export/IPS/repo and the pkg/readonly property to true. Set the preferred publisher by using pkg set-publisher -G http://pkg.oracle.com/solaris/release/ \

    -g http”//serverA.example.com/ solaris

  2. cat so1.repo.iso-a so1.repo.iso-b gt; /export/IPS/repo

    Set the pkg/inst_root property to true and the pkg/readonly property to /export/IPS

    Set the preferred publisher by using pkg set-publisher -G http://serverA.example.com/ \

    -g http://pkg/oracle.com/solaris/rekease/solaris

  3. cat so1.repo.iso-a so1.repo.iso-b gt; so1.full.iso

    Mount the ISO image and use the rsync command to extract the contents of the ISO file to

    /export/IPS/repo

    Set the pkg/inst_root property to /export/IPS/repo and the pkg/readonly property to true Set the preferred publisher by using pkg set-publisher solaris \

    -g http://pkg.oracle.com/

  4. cat so1.repo,iso-a so1.repo.iso-b gt; /export/IPS/repo.iso

Mount the ISO image and copy the repo directory from the ISO image to /export/IPS/repo set the pkg/inst_root property and the pkg/readonly property to /export/IPS/repo

set the preferred pkg/inst_root property by using pkg set-publisher – G http://serverA.example.com/ \

  • g http://pkg.oracle.com/solaris.com/release/- p solaris

  • Answer: D

    Explanation: Concatenate the files into one file using the cat command.

    Make the contents of the repository .iso file available using the mount command.

    To increase the performance of repository accesses and to avoid the need to remount the .iso image each time the system restarts, copy the repository files from /mnt/repo/to a

    ZFS file system. You can do this copy with rsync or with tar.

    Question No: 68

    The COMSTAR framework provides support for the iSCSI protocol. Select three options that correctly describe the COMSTAR framework.

    1. iSCSI devices can be used as dump devices.

    2. SCSI commands are carried over IP networks and enable you to mount disk devices from across the network onto your local system.

    3. Large amounts of data can be transferred over an IP network with very little network degradation.

    4. COMSTAR allows you to convert any Solaris11 host into a SCSI target device that can be accessed over a storage network.

    5. One IP port can handle multiple ISCSI target devices.

    Answer: B,D,E

    Explanation: B: By carrying SCSI commands over IP networks, the iSCSI protocol enables you to access block devices from across the network as if they were connected to the local system. COMSTAR provides an easier way to manage these iSCSI target devices.

    D: Common Multiprotocol SCSI TARget, or COMSTAR, a software framework that enables you to convert any Oracle Solaris 11 host into a SCSI target device that can be accessed over a storage network by initiator hosts.

    E: One IP port can handle multiple iSCSI target devices.
