Oracle 1Z0-100 Online Questions & Answers

• Question 31:

  What is the purpose of Setting AUTOINSTALL to YES /etc/uptrack.conf?

  A. To install Ksplice kernel updates during the reboot of a system
  B. To install updates to the Ksplice software Itself during a system reboot
  C. To enable the uptrack cron job to install Ksplice kernel updates whenever they become available
  D. To enable Ksplice to automatically install the kernel rpm whenever new Ksplice kernel updates become available
  E. To enable Ksplice to install Ksplice kernel updates and new kernel RPMS whenever they become available
  D. To enable Ksplice to automatically install the kernel rpm whenever new Ksplice kernel updates become available

  ---

  If you'd like Ksplice Uptrack to automatically install updates as they become available, run:

  sh install-uptrack YOUR_ACCESS_KEY --autoinstall

  in place of the above install-uptrack command, or set "autoinstall = yes" in your /etc/uptrack/uptrack.conf after installation.

  Note: Automatic updates

  You can configure your systems to automatically install updates as they become available. To enable autoinstall, set autoinstall = yes in your /etc/uptrack/uptrack.conf, or pass the --autoinstall flag during installation.

  Autoinstall is our most popular configuration. It is a scalable way to ensure that updates get installed quickly as they become available, regardless of when they are released.

  Please note that enabling autoinstall does not mean the Uptrack client itself is automatically upgraded. You will be notified via e-mail when a new Uptrack client is available, and it can be upgraded through your package manager.
