  3. Diffie-Kerberos coaxial key encryption
  4. Signed cryptographic plugins (providers)
  5. Kernel support for signed antivirus plugins

Question 2

Which five statements describe options available for installing the Oracle Solaris 11operating system using the installation media?

  1. You can perform a text or LiveCD installation locally or over the network.
  2. The text Installer does not install the GNOME desktop. The GNOME desktop package must he added after you have installed the operating system.
  3. The LiveCD Installation cannot be used to install multiple instances of Oracle Solaris.
  4. 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.
  5. The LiveCD Installer is for x86 platforms only.
  6. The GUI installer cannot be used to upgrade your operating system from Solaris 10.
  7. 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.
  8. The LiveCD installer can be used for SPARC or x86 platforms.

Question 3

Review the zonestat command: zonestate - q physical - memory -R high -z -p -p "zones" 10 24h 60m Select the option that correctly describes the information that is displayed by this command.

  1. It is a sample of dbzones physical memory usage taken every hour over a 24-hour period. Only the top 10 samplings of peak memory usage are displayed. All other utilization data is eliminated.
  2. It is a sample of dbzones CPU, virtual memory, and networking utilization. Physical memory is executed from the report. The sampling is taken every 10 minutes over a 24-hour period and peak utilization id displayed each hour.
  3. It is a sample of dbzones CPU, virtual memory, and networking utilization. Physical memory is executed from the report. The sampling is taken every 10 minutes over a 24-hour period and displayed each hour.
  4. It is a sample of dbzones physical memory usage taken every 10 seconds and 24-hour period. Only peak virtual memory usage and CPU utilization are displayed each hour. All other Utilization data is eliminated.
  5. It is a sample of dbzones physical memory usage taken every 10 seconds and 24-hour period. Only peak memory usage is displayed each hour. All other utilization data is eliminated.

Question 4

You are configuring NFS on a server. Select the two statements that are true.

  1. Resources listed in /etc/dfs/dfstab are automatically shared on boot up.
  2. A directory cannot be shared if a subdirectory below it is already shared.

  4. NFS and SMB protocols cannot be used simultaneously to share the same directory.

Question 5

You have already generated a 256-bit AES raw key and named the keystore file /mykey. You need to use the key to create an encrypted file system. Which command should you use to create a ZFS encrypted file system named pool1/encrypt using the /mykey keystore?

  1. zfs create - o encryption = /mykey pool1/encrypt
  2. zfs create - o encryption = 256-ccm - o keysource = raw, file : ///my key pool1/encrypt
  3. zfs create - o encryption = AES keysource = /mykey pool1/encrypt
  4. zfs create - o encryption = on keystore = /mykey pool1/encrypt
