Question 4

Question
An administrate 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.
Answer
  • A. This Is true because the domain files can be re created with the pack and unpack utilities.
  • B. 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.
  • C. 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.
  • D. 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).

Question 5

Question

  • F. The managed servers that Nod Manager started go into ADMIN mode if they can no longer communicate with Node Manager.

Question 6

Question
QUESTION NO: 6 You configure a data source with a non XA driver because your (non-Oracle) database does not provide XA drivers. The data source will sometimes participate in global transactions with an EJB, so as you configure the data source you select “Supports Global Transactions” and One-phase commit. Why is this configuration wrong?
Answer
  • A. You must choose an XA driver when a data source participates In global transactions.
  • B. "One' Phase Commit" always returns "ready" during phase one of the two-phase commit process’ so it is possible you will have heuristic errors in the database.
  • C. "One-Phase Commit" processes this data source last In the global transactions, if the EJB must go last, you cannot use this configuration.
  • D. "One-Phase Commit" only allows this data source to participate in global transaction, so you cannot have a global transaction that includes an EJB.
