Questions 31

An administrator in your organization says you do not need to back up the domain files on a machine which only managed servers run.

Select the best explanation for this statement.

Options:

This is true because the domain files can be re-created with the pack and unpack utilities.

This is true (with an exception) because the domain files can be re-created with the pack and unpack utilities. The exception is if your security realm uses the embedded LDAP system. Which is not included in the JAR file created by the pack utility.

This is true (with an exception) because the domain files can be re-created with the pack and unpack utilities. The exception is for applications that are deployed to the managed server. Those files are not included in the JAR file created by the pack utility. If you back those up manually, then pack and unpack can be used.

This is not true. You need to back up the domain files on a machine on which only managed servers run by using operating system commands (such as tar or zip).
