• Question 83:

  In order to increase scalability and high availability you are configuring WebLogic clustering with JMS distributed destinations.

  Which recommendation will ensure optimal load balancing of the message processing?

  A. The machines that host the cluster should have similar processing power, disk space, and memory.

  B. The cluster should include at least one configurable server.

  C. The cluster should use unicast communication.

  D. All servers in the cluster should be assigned to the same WebLogic machine.

  Correct Answer: A

  A uniform distributed destination (UDD), compared to weighted Distributed Destinations, greatly simplifies the management and development of distributed destination applications.Using uniform distributed destinations, you no longer need to create or designate destination members, but instead rely on WebLogic Server to uniformly create the necessary members on the JMS servers to which a JMS module is targeted. This feature ensures the consistent configuration of all distributed destination parameters, particularly in regards to weighting, security, persistence, paging, and quotas.

  Incorrect Answers:

  C: The benefits of multicasting include:

  Near real-time delivery of messages to host group.

  High scalability due to the reduction in the amount of resources required by the JMS server to deliver

  messages to topic subscribers in a cluster.

  D: A distributed destination is a set of destinations (queues or topics) that are accessible as a single,

  logical destination to a client. A distributed destination has the following characteristics:

  *

  It is referenced by its own JNDI name.

  *

  Members of the set are usually distributed across multiple servers within a cluster, with each destination

  member belonging to a separate JMS server

• Question 84:

  Some of the messages entering a JMS queue are expiring and are being removed from the queue. You need better insight regarding these expired messages.

  Which mechanism helps achieve this? (Choose the best answer.)

  A. Set the "Log Expired Message" attribute to true for the queue.

  B. Associate an ExpirationEventHandler object for the queue.

  C. Enable Message Life Cycle logging for the JMS Queue.

  D. Configure an Expiration Event Handler for the JMS Queue which logs the expired message properties.

  Correct Answer: B

  The Expiration Policy log option removes expired messages from the system and writes an entry to the server log file indicating that the messages have been removed from the system. The actual information that is logged is defined by the Expiration Logging Policy.

  Reference: https://docs.oracle.com/cd/E13222_01/wls/docs81/ConsoleHelp/ domain_jmsqueue_config_expiration-policy.html

• Question 85:

  Even though your company has a thorough procedure for testing applications in a pre-production environment prior to production deployment, you have decided to conduct additional testing of a particular application after it is deployed. You choose to deploy the application in administration mode.

  Which three statements are true? (Choose three.)

  A. The application deployment must use the 璻edeploy option using a unique version string.

  B. You must configure an administration port for the entire domain, or an administration channel for the targeted server.

  C. The application must first be distributed to the targeted server prior to starting it in administration mode.

  D. The application cannot have any dependencies on any shared Java EE libraries.

  E. After testing, the application can be dynamically transitioned to start accepting all client requests.

  Correct Answer: BCE

  B: Distributing an application copies deployment files to target servers and places the application in a prepared state. You can then start the application in Administration mode, which restricts access to the application to a configured Administration channel so you can perform final testing without opening the application to external client connections or disrupting connected clients.

  C: Distributing an application prepares it for deployment by copying its deployment files to all target servers and validating it. After you distribute an application, you can start it in Administration mode, which restricts access to the application to a configured Administration channel and allows you to distribute the application to a production environment (or distribute a new version of an application) without opening the application to external client connections.

  E: While in Administration mode, you can connect to an application only via a configured Administration channel. This allows you to perform final ("sanity") checking of the application directly in the production environment without disrupting clients. After performing final testing, you can either undeploy the application to make further changes, or start the application to make it generally available to clients.

  Incorrect Answers:

  A: After performing final testing, you can either undeploy the application to make further changes, or start the application in Production mode to make it generally available to clients.

• Question 86:

  Which three statements are correct regarding the WLST create command? (Choose three.)

  A. When the create command is used with WLST online, the connection must be to the administration server.

  B. The type of MBean being created must be a child type of the current management object.

  C. The correct order of the mandatory parameters for the create statement is name followed by childMBeanType.

  D. The create command is used to create any configuration or runtime management bean.

  E. The create command returns a WLSTProgress object.

  Correct Answer: ABC

  A: When using the create command with WLST online you must be connected to an Administration Server.

  B: Child types must be created under an instance of their parent type.

  C: Syntax: create(name, childMBeanType, [baseProviderType])

  The Create command creates a configuration bean of the specified type for the current bean.

  Incorrect Answers:

  D: The create command returns a stub for the newly created configuration bean. It can't create a runtime

  management bean.

  E: The create command returns a stub for the newly created configuration bean.

• Question 87:

  You need to ensure that when a failed admin server instance is restarted on another machine with a different IP address, the managed server is able to establish connection with the newly started instance.

  Which technique will ensure that the connection can be made? (Choose the best answer.)

  A. Configure a DNS name for AdminServer which maps to multiple IP addresses and specify this DNS name during managed server startup.

  B. Specify multiple admin server IP addresses during managed server startup.

  C. Use WLST to update the AdminServer IP address for a running managed server.

  D. Update the host file for a running managed server instance.

  Correct Answer: C

  You can change the network configuration of Oracle HTTP Server and Oracle Web Cache by using the following command:

  (UNIX) ORACLE_HOME/chgip/scripts/chpiphost.sh (Windows) ORACLE_HOME\chgip\scripts\chpiphost.bat

  The format of the command is:

  chgiphost.sh | chgiphost.bat

  [-noconfig] [-version] [-help]

  [ -oldhost old_host_name -newhost new_host_name]

  [-oldip old_IP_address -newip new_IP_address]

  -instanceHome Instance_path

• Question 88:

  Which three WebLogic Server entities can be set up for service level migration? (Choose three.)

  A. JMS Server

  B. JOLT Service

  C. JTA Transaction Recovery Service

  D. User Defined Singleton Service

  E. JDBC Service

  F. JNDI Service

  Correct Answer: ACD

  AC: WebLogic Server migration framework provides infrastructure and facilities to perform the manual or automatic migration of JMS-related services and the JTA Transaction Recovery Service.

  D: WebLogic Server supports the automatic migration of user-defined singleton services.

  Automatic singleton service migration allows the automatic health monitoring and migration of singleton

  services. A singleton service is a service operating within a cluster that is available on only one server at

  any given time.

  Reference: http://docs.oracle.com/cd/E17904_01/web.1111/e13709/service_migration.htm#CLUST373

• Question 89:

  You intend to introduce ordering in message processing for your JMS destination by creating a destination key.

  Which statement is true about the JMS Destination Key configuration? (Choose the best answer.)

  A. A JMS Destination Key cannot be specified using WLST.

  B. A JMS Destination Key cannot be used to sort messages in a Last In First Out order.

  C. A JMS Destination Key allows a user-defined sort key.

  D. A Destination Key can be applied to the message body.

  Correct Answer: A

  The WebLogic Server Administration Console enables you to configure, modify, target, and delete destination key resources in a system module.

  Incorrect Answers:

  B: As messages arrive on a specific destination, by default they are sorted in FIFO (first-in, first-out) order,

  which sorts ascending based on each message's unique JMSMessageID. However, you can use a

  destination key to configure a different sorting scheme for a destination, such as LIFO (last-in, first-out).

  C: Attribute Sort Key: The message sort key or the name of a message header field on which to sort.

  Message header field keys start with the letters JMS and ignore the key type setting.

  Valid values only (user-defined sort key not possible):

  JMSMessageID JMSTimestamp JMSCorrelationID JMSPriority JMSExpiration JMSType JMSRedelivered JMSDeliveryTime

• Question 90:

  Which are three valid actions of the Post Domain Creation process? (Choose three.)

  A. Import LDAP data from XML files.

  B. Run pack and unpack commands for managed servers on remote machines.

  C. Run any SQL scripts to generate database artifacts.

  D. Use WLST to run the postdomain.py script.

  E. Run the root.sh script.

  F. Assign DNS names to all the hosts.

  G. Run the RCU utility for each hosted application.

  Correct Answer: CEG

  E: Following installation of your product, you need to run the root.sh script as the root user. The root.sh script detects settings of environment variables and enables you to enter the full path of the local bin directory.

  G: RCU is a Fusion Middleware tool which creates database-based repositories. Oracle Data Service Integrator does not have a repository by itself, but it relies on some Fusion Middleware schemas for WebLogic Server and JCF when using a full domain.
