A. Create and use a custom log filter

B. Redirect standard output to the log

C. Increase the severity level

Question 2

You are using the administration console to monitor transactions on a managed server. In the Summary subtab, under the JTA tab, you notice that the total count of transactions does not equal the sum of the committed transactions and all of the various rolled back transaction categories. How do you explain this?

A. The total count includes distributed and local transactions. The committed count and the various rolled back counts are for distributed transactions only

B. The total count includes all transactions since the server was started. The other counts only include the transactions included in the latest transaction log

C. The total count field includes in-progress transactions, but the others only show completed transactions

D. The total count field includes committed, rolled back, and heuristic completions

Correct Answer: D

Question 3

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?

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.

Correct Answer: D

Question 4

Which three statements are true about the Change Center in the Administration Console? (Choose three.)

A. The Change Center has a link to view any servers that need to be restarted

D. Locking the console prevents other privileged users from taking the lock until you release it or activate your changes

E. The Change Center has a link to view the changes made so far

F. After activating the changes to a server's configuration, you must always restart that server

Correct Answer: A,C,E

A. Update the credentials in the start script

B. Add the option to the start script that allows servers to be started without credentials

A. Use the script enrollNodeManager.sh found under the WEBLOGIC_HOME directory in server/bin

B. You create a managed server template by using the pack utility. Then create the domain by using the unpack utility on the new machine where Node Manager will run

C. Use the administration console. Select the machine, then the Configuration and Node Manager tabs.
