Oracle 1Z0-821 Online Questions & Answers

• Question 61:

  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?

  A. 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.
  B. If you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 30.
  C. ZFS encryption is integrated with the ZFS command set and no additional packages need to be installed.
  D. 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 pool must be upgraded to ZFS version 21, minimum.
  F. Encryption is supported at the pool or dataset (file system) level.
  G. Encryption is supported at the pool level only for every file system in the pool will be encrypted.
  H. 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.
  A. 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.
  B. If you plan to create an encrypted file system in an existing zpool, the zpool must be upgraded to ZFS version 30.
  C. ZFS encryption is integrated with the ZFS command set and no additional packages need to be installed.
  F. Encryption is supported at the pool or dataset (file system) level.

  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 62:

  Your task is to convert a JumpStart sysidcfg file to an Automated Installer (AI) sc_profile.xml file, using js2ai. Select two unsupported items that will require changes.

  State can be: disabled, down, duplicate, inaccessible, ok, tentative

  Example: # ipadm show-addr ADDROBJ TYPE STATE ADDR lo0/v4 static ok 127.0.0.1/8 lo0/v6 static ok ::1/128

• Question 65:

  You want to install the openldap software package to a now boot environment for testing before introducing the now software package to the production environment. What option describes the correct procedure to:

  1) create a new BE named nowBE

  2) install the software to that new BE only

  A. pkg install --newBE openldap
  B. pkg install --be-nama newBE openldap
  C. beadm create newBEbeadm mount newBE /mntpkg -R /mnt update openldap
  D. beadm create newBEbeadm activate newBEpkg install openldap
  D. beadm create newBEbeadm activate newBEpkg install openldap

  If you want to create a backup of an existing boot environment, for example, prior to modifying the original boot environment, you can use the beadm command to create and mount a new boot environment that is a clone of your active boot environment. This clone is listed as an alternate boot environment in the GRUB menu for x86 systems or in the boot menu for SPARC systems.

  When you clone a boot environment by using the beadm create command, all supported zones in that boot environment are copied into the new boot environment.

  How to Create a Boot Environment

  1.

  Become the root role.

  2.

  Create the boot environment.

  # beadm create BeName

  BeName is a variable for the name of the new boot environment. This new boot environment is inactive.

  3.

  (Optional) Use the beadm mount command to mount the new boot environment.

  # beadm mount BeName mount-point

  Note: If the directory for the mount point does not exist, the beadm utility creates the directory, then mounts the boot environment on that directory.

  If the boot environment is already mounted, the beadm mount command fails and does not remount the boot environment at the newly specified location.

  4. (Optional) Activate the boot environment.

  # beadm activate BeName

  BeName is a variable for the name of the boot environment to be activated.

  On reboot, the newly active boot environment is displayed as the default selection in the x86 GRUB menu or the SPARC boot menu.

• Question 66:

  C. The time zone.
  D. A default user account.
  E. The terminal type.
  F. The root password.
  G. The host name.
  A. The IP address.
  B. The name service.
  C. The time zone.

  ---

  IP address and name service (such as a DNS server) are provided by the DHCP server.

• Question 67:

  A user jack, using a korn shell, requests a directory listing as follows: jack@solaris:/export/home/jack $ 1s File filea Filea fileb Fileb filec Filec

  Which two statements are correct?

  A. The pattern [?i]*a will expand to filea Filea.
  B. The pattern [fF]*a? will expand to [fF] *a?.
  C. The pattern [gfe] * will expand to file filea fileb filec.
  D. The pattern [g-e] * will expand to file filea fileb filec.
  E. The pattern [fF] [a-zA-z] i*e will expand to file.
  A. The pattern [?i]*a will expand to filea Filea.
  C. The pattern [gfe] * will expand to file filea fileb filec.

• Question 68:

  You are logged in to a Solaris 11 system as user jack. You issue the following sequence of commands:

  

  Identify two correct statements.

  A. You have the effective privilege of the account root.
  B. Your GID is 10.
  C. Your home directory is /root.
  D. You are running the shell specified for the account root.
  E. Your UID is 1.
  A. You have the effective privilege of the account root.
  B. Your GID is 10.

  ---

  Oracle Solaris provides predefined rights profiles. These profiles, listed in the /etc/security/prof_attr, can be assigned by the root role to any account. The root role is assigned all privileges and all authorizations, so can perform all tasks, just as root can when root is a user.

  To perform administrative functions, you open a terminal and switch the user to root. In that terminal, you can then perform all administrative functions.

  $ su - root Password: Type root password # When you exit the shell, root capabilities are no longer in effect.

• Question 69:

  Before booting test zone a non-global zone, you want to connect to the zone's console so that you can watch the boot process.

  Choose the command used to connect to testzone's console.

  A. zoneadm -C testzone
  B. zoneadm -console testzone
  C. zlogin - z testzone console
  D. zlogin - z testzone - C
  E. zlogin -C testzone
  F. zoneadm - testzone - c
  E. zlogin -C testzone

  ---

  The following options are supported:

  C

  Connects to the zone console. Connects to the zone console.

  Note:

  After you install a zone, you must log in to the zone to complete its application environment. You might log in to the zone to perform administrative tasks as well. Unless the -C option is used to connect to the zone console, logging in to a zone

  using zlogin starts a new task. A task cannot span two zones

• Question 70:

  Which three options describe the purpose of the zonep2vchk command?

  A. Used on a Solaris 10 global zone to access the system for problems before migrating that system to a Solaris 10 branded zone.
  B. Used to access a Solaris 10 global zone for problems before migrating that zone to a Solaris 11 global zone
  C. Used to create zonecfg template for a Solaris 10 global zone that that will be migrated to a solaris10 branded zone.
  D. Used to migrate an Oracle Solaris 11 global zone to a non-global zone.
  E. Used to migrate a Solaris 10 global zone to a non-global zone on the same server; the non-global zone can then be migrated to a Solaris 11 server as a Solaris10 branded zone.
  C. Used to create zonecfg template for a Solaris 10 global zone that that will be migrated to a solaris10 branded zone.
  D. Used to migrate an Oracle Solaris 11 global zone to a non-global zone.
  E. Used to migrate a Solaris 10 global zone to a non-global zone on the same server; the non-global zone can then be migrated to a Solaris 11 server as a Solaris10 branded zone.

  zonep2vchk

  - check a global zone's configuration for physical to virtual migration into non-global zone

  The zonep2vchk utility is used to evaluate a global zone's configuration before the process of physical-to-virtual (p2v) migration into a non-global zone. The p2v process involves archiving a global zone (source), and then installing a non-global zone (target) using that archive Zonep2vchk serves two functions. First, it can be used to report issues on the source which might prevent a successful p2v migration. Second, it can output a template zonecfg, which can be used to assist in configuring the non-global zone target. Zonep2vchk can be executed on a Solaris 10 or later global zone. To execute on Solaris 10, copy the zonep2vchkutility to the Solaris 10 source global zone. When run on Solaris 10, a target release of S11 can be specified, which will check for p2v into a Solaris 10 Branded zone.
