• Question 22:

  You have been tasked with replacing an existing WebLogic domain with a brand new installation as part of a migration. The new server needs to use the previously created JDBC store that holds existing JMS messages.

  Which two configuration requirements do you need to comply with in order to make the transition successful? (Choose two.)

  B. The new domain name needs to be the same as the old domain it's replacing

  C. Duplicate the JMS and persistent store configuration in the new domain

  D. The storage needs to be file based and not JDBC based

  E. Set the prefix for the JDBC store table to the domain name

  Correct Answer: AE

• Question 23:

  You start a managed server by running a start script at the command line. The server fails to start. To

  troubleshoot this failure, you look at the window in which the script ran. One of the messages form the

  server says: "boot identity not valid".

  What do you do before running the script again?

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

  B. Update the credentials in the boot identity file

  C. Update the credentials in the start script

  D. Create a boot identity username and password by using the administration console

• Question 24:

  You are responsible for installing and setting up WebLogic Server to support the development, testing, and production of an application. Each phase of the application's life cycle has different scalability, performance, and security requirements.

  How will you implement this?

  A. Create a single domain with three clusters

  B. Create a single domain with three administration servers

  C. Create a single domain with three managed servers

  D. Create three domains

  Correct Answer: C

• Question 25:

  You are running WebLogic Server under a 64-bit HotSpot JVM.

  You edit your domain's setDomainEnc.sh script to update the minimum and maximum heap sizes as

  follows:

  USER_MEM_ARGS=”-Xms32meg –Xmx150meg”

  Export USER_MEM_ARGS

  You try to start a managed server by running the domain start script at the command line. The server fails

  with the message:

  Invalid initial heap size: -Xms32meg

  Why does the server fail with that message?

  A. The minimum heap size for a 64-bit JVM is 64 Megabytes

  B. For performance reasons, the minimum heap size and maximum heap size should be the same value

  C. The parameter value was entered incorrectly. The correct value is: “-Xms32m –Xmx150m”

  D. The parameter value was entered incorrectly. You must enter memory parameter values in Kilobytes

  E. The parameter value was entered incorrectly. The correct value is: “-Xms:32meg – Xmx:150meg”

  Correct Answer: C

  Correct Answer: DE

• Question 28:

  A. State

  B. Active Connections Current Count

  C. Connection Delay Time

  D. Leaked Connection Count
