Question #11
Examine the domain diagram:

What is the correct path within the configuration hierarchy to the MBean that contains the log rotation parameters for server04? (Choose the best answer.)
  1. A
    /Servers/server04/Log/server04
  2. B
    /server04/log/rotation
  3. C
    /Cluster01/server04/log
  4. D
    /Machine02/server04/log
  5. E
    /Logs/server04
  6. F
    /TestDomain/server04/log
  7. G
    /server04/log

Correct Answer:
D
By default, the rotated files are stored in the same directory where the log file is stored.
The server log file is located on the computer that hosts the server instance. By default, the server log file is located below the server instance's root directory: root-directory\server-name\server-name.log. https://docs.oracle.com/cd/E28280_01/web.1111/e13739/config_logs.htm#WLLOG139

Question #12
Which two automatic migration scenarios require node manager for all migratable services? (Choose two.)
  1. A
    Consensus leasing
  2. B
    Database leasing with no pre and post migration scripts
  3. C
    Database leasing with pre and post migration scripts
  4. D
    Synchronous leasing

Correct Answer:
AC
When using automatic service migration, the Node Manager is required to get health monitoring information about the member servers involved, as follows:
* Consensus leasing Node Manager must be running on every machine hosting managed servers within the cluster.
* Database leasing Node Manager must be running on every machine hosting managed servers within the cluster only if pre/post-migration scripts are defined. If pre/post-migrations are not defined, then Node manager is not required.

Question #13
Which two statements are true about the role of cluster master in whole server migration? (Choose two.)
  1. A
    There is exactly one cluster master in the cluster at a given point of time.
  2. B
    The cluster master must host all the pinned services in the cluster.
  3. C
    Any managed server in the cluster can serve as the cluster master.
  4. D
    A cluster master must always be different from a singleton master.
  5. E
    The cluster master must always be started with the node manager.

Correct Answer:
AC
One server instance in a cluster that contains migratable servers acts as the cluster master and orchestrates the process of automatic server migration, in the event of failure.
Any Managed Server in a cluster can serve as the cluster master, whether it hosts pinned services or not.
Note: Any server instance in the cluster can serve as the cluster master. When you start a cluster that contains migratable servers, the first server to join the cluster becomes the cluster master and starts up the cluster manager service. If a cluster does not include at least one migratable server, it does not require a cluster master, and the cluster master service does not start up.

Question #14
You are trying to set up a JMS Session with a specified acknowledgment mode. You want the application that receives the message to explicitly take care of the acknowledgment.
Which option represents a valid choice for the acknowledgment mechanism that you can use? (Choose the best answer.)
  1. A
    AUTO_ACKNOWLEDGE
  2. B
    CLIENT_ACKNOWLEDGE
  3. C
    DUPS_OK_ACKNOWLEDGE
  4. D
    DEFAULT_ACKNOWLEDGE

Correct Answer:
B
With CLIENT_ACKNOWLEDGE the Session object relies on the application to call an acknowledge method on a received message. Once the method is called, the session acknowledges all messages received since the last acknowledge.
Incorrect Answers:
A: With CLIENT_ACKNOWLEDGE the Session object acknowledges receipt of a message once the receiving application method has returned from processing it.
C: With DUPS_OK_ACKNOWLEDGE the Session object acknowledges receipt of a message once the receiving application method has returned from processing it; duplicate acknowledges are permitted.
D: There is no acknowledge mode named DEFAULT_ACKNOWLEDGE.

Question #15
You created a script to monitor your WebLogic Server WLS Execute Thread:

Here is a message in your ExecuteThread.log file:

What is the value of xxxx if the thread has been running a request for twenty minutes, assuming a default configuration?
  1. A
    SRANDBY
  2. B
    ACTIVE
  3. C
    STUCK
  4. D
    RUNNING
  5. E
    WAITING
  6. F
    ADMIN
  7. G
    FAILED

Correct Answer:
C
This thread is considered Stuck by WebLogic because it's been running for over the time defined in MaxStuckThreadTime (600 seconds by default). Weblogic
Server waits for this time to be reached before marking a thread as stuck if the thread is still working after this time.
Example: [STUCK] ExecuteThread: '2' for queue: 'weblogic.kernel.Default (self-tuning)' id=73 idx=0x128 nid=13410 prio=1 alive, in native, daemon
