Question No.91

Select two statements that correctly describe the capabilities of the Distribution Constructor.

  1. ISO images for use with the Automated Installer (AI) can be created.

  2. Bootable USB images can be created for SPARC and x86 architectures.

  3. A single installation server can be used to create ISO images for SPARC and x86 architectures.

  4. Checkpoints can be used to pause the build, allowing scripts to run that modify the resulting ISO Image.

  5. A single Installation server can be used to create ISO images for Solaris 10 and Solaris11 operating systems.

    Correct Answer: AD

    Explanation:

    A: You can use the distribution constructor to create the following types of Oracle Solaris images:

    image

    image

    1. x86 or SPARC ISO Image for Automated Installations Oracle Solaris x86 live CD image

image

image

x86 or SPARC Oracle Solaris text installer image x86 Oracle Solaris Virtual Machine

Note:

You can use the distribution constructor to build custom Oracle Solaris images. Then, you can use the images to install the Oracle Solaris software on individual systems or multiple systems. You can, also, use the distribution constructor to create Virtual Machine (VM) images that run the

Oracle Solaris operating system.

D: Checkpointing Options

You can use the options provided in the distro_const command to stop and restart the build process at various stages in the image-generation process, in order to check and debug the image that is being built. This process of stopping and restarting during the build process is called checkpointing.

  1. The zone.cfg file is a text file in a zonecfg export format.

  2. The zone.cfg file is an Al manifest that specifies how the zone is to be installed.

  3. The zone.cfg file is an XML file in a form suitable for use as a command file for the zonecfg command.

  4. The zone.cfg file is an SC profile with keywords that are specific for configuring a zone as part of the installation process.

  5. ft is an 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

Correct Answer: A

Question No.96

You upgraded your server to Oracle Solaris 11 and you imported zpool (pool1) that was created in Solaris 10. You need to create an encrypted ZFS file system in pool1, 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 Solaris11. To encrypt a ZFS file system from a previous version of Solaris, upgrade the zpool and create a new encrypted ZFS file system into the 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.

  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.

  5. If you plan to create an encrypted file system in an existing zpool, the pool must be upgraded to ZFS version 21, minimum.

  6. Encryption is supported at the pool or dataset (file system) level.

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

  8. You cannot create an encrypted file system in a zpool that was created prior to oracle Solaris11. Create a new zpool in Solaris11, 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.

Correct Answer: ABCF

Explanation:

A (not H): You can use your existing storage pools as long as they are upgraded. You have the flexibility of encrypting specific file systems.

B (not E): Can I enable encryption on an existing pool? Yes, the pool must be upgraded to pool version 30 to allow encrypted ZFS file systems and volumes.

C (not D): ZFS encryption is integrated with the ZFS command set. Like other ZFS operations, encryption operations such as key changes and rekey are performed online.

F (not G): Encryption is the process in which data is encoded for privacy and a key is needed by the data owner to access the encoded data. You can set an encryption policy when a ZFS dataset is created, but the policy cannot be changed.

Question No.97

The current ZFS configuration on server is:

image

You need to backup the /data file system while the file system is active.

Select the option that creates a full backup of the /data file system and stores the backup on server in the pool named backup.

  1. Mount -F nfs system: /backup / mnt

    zfs snapshot pool/data@mondaygt;/mnt/Monday

  2. Mount -F nfs systemB: /backup/mnt zfs snapshot pool1/data@Monday

    zfs clone pool1/data@monday/mnt/Monday

  3. Zfs send pool1/data@Monday | ssh system zfs recv backup/monday

  4. Zfs snapshot pool1/data@Monday | ssh system zfs recv backup/monday

Correct Answer: D

Explanation:

Question No.99

You are troubleshooting the Oracle Solaris11 Automated Installer (AI), which is not connecting with the IPS software repository. Which three steps will help determine the cause of DNS name resolution failure?

  1. Verify the contents of /etc/resolve.conf.

  2. Run netstat -nr to verify the routing to the DNS server.

  3. Ping the IP address of the IPS server to verify connectivity.

  4. On the installation server, verify that the menu.1st file for the client points to a valid boot arc hive.

  5. Run df -k to verify that the boot directory containing the boot archive is loopback mounted under

    /etc/netboot.

  6. Run the command /sbin/dhcpinfo DNSserv to ensure that the DHCP server providing the DNS server information.

Correct Answer: ABF

Explanation:

Check DNS

(A) Check whether DNS is configured on your client by verifying that a non-empty /etc/resolv.conf file exists.

(F) If /etc/resolv.conf does not exist or is empty, check that your DHCP server is providing DNS server information to the client:

# /sbin/dhcpinfo DNSserv

If this command returns nothing, the DHCP server is not set up to provide DNS server information to the client. Contact your DHCP administrator to correct this problem.

(B) If an /etc/resolv.conf file exists and is properly configured, check for the following possible problems and contact your system administrator for resolution:

** The DNS server might not be resolving your IPS repository server name.

** No default route to reach the DNS server exists.

Question No.100

You create a flash archive of the Solaris 10 global zone on the serves named sysA. The archive name is s10-system.flar, and it is stored on a remote server named backup_server.

On sysA, you create a Solaris 10 branded zone named s10-zone.

You want to use the flash archive, located Onquot; /net/bactup_servers/10-system.flar, to install the Operating system in the s10-zone zone.

Which command do you choose to install the s10-system.flar archive in the Solaris 10 branded zone (s10-zone)?

  1. zoneadm -z s10 -zone install – a /net/backup_server/s10-system.flar -u

  2. zonecfg -z s10 -zone install – a /net/backup_server/s10-system.flar -u

  3. zoneadm – z s10 -zone clone – s /net/backup_server/s10-system.flar

  4. zone cfg – a s10-zone create – t SUNWsolaris10\ lt;/net/backup_server/s10-system.flar

  5. zonecfg -z s10-zone install -f /net/backup/backup_server/s10-system.flar

Correct Answer: A

Explanation:

The zoneadm command is the primary tool used to install and administer non-global zones.

Operations using the zoneadm command must be run from the global zone on the target system.

How to Install the solaris10 Branded Zone

A configured solaris10 branded zone is installed by using the zoneadm command with the install subcommand.

Example:

global# zoneadm -z s10-zone install -a /net/machine_name/s10-system.flar -u
