NEW QUESTION 1
Your WebLogic domain is experiencing a problem. You want to use the WebLogic Diagnostic Framework (WLDF) to diagnose the problem. You have a support case open with Oracle Support, and they have requested a diagnostic image of your server that is experiencing the problem.
The problem is not predictable or reproducible on-demand, but you noticed that the number of requests waiting to execute increases dramatically when the problem does occur. The problem also seems to occur at any time of the day or night.
How would you approach reliably capturing a diagnostic image that contains data that is relevant to the problem that is occurring?

• A. Configure a WLDF watch that triggers a diagnostic image action when the number of requests waiting to execute exceeds a certain threshold.
• B. Configure WebLogic overload protection to automatically trigger a diagnostic image when the number of requests waiting to execute exceeds a certain threshold.
• C. Manually monitor the number of requests waiting to execute and create a diagnostic image when you see the number of requests waiting to execute exceeds a certain threshold.
• D. Configure the server health failure action to trigger a diagnostic image when the number of requests waiting to execute exceeds a certain threshold.

Answer: A

Explanation:
The Watch & Notifications (W&N) system consumes data generated by other parts of WLDF (MBean data through the Harvester, as well as data from Instrumentation and/or Log events) and applies configured rules against that data. If a rule evaluates to true, W&N can generate a notification over SNMP, SMTP, JMX, JMS, or any combination therein. WLDF supports the following types of notifications:
Diagnostic Images
Java Management Extensions (JMX) Java Message Service (JMS)
Simple Mail Transfer Protocol (SMTP), for example, e-mail Simple Network Management Protocol (SNMP)

NEW QUESTION 2
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 propertie

Answer: B

Explanation:
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.

NEW QUESTION 3
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 applicatio

Answer: CEG

Explanation:
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.

NEW QUESTION 4
Which three types of information can an Extension Template contain? (Choose three.)

• A. JMS
• B. JDBC
• C. sample application
• D. servers
• E. clusters
• F. machines
• G. administration username and password

Answer: ABC

Explanation:
Optionally, you can define parameters for Java Message Service (JMS) in the Extension Template. Optionally, you can customize the Java Database Connectivity (JDBC) settings in the Extension Template. You can review and modify, if desired, the list of applications to be included in your extension template.

NEW QUESTION 5
You need to update a database accessed by an application that uses a WebLogic server data source. It has been decided that the data source on WLS should first be shut down.
You have been asked to advise as to whether they should execute a shutdown() or a forceShutdown() on the corresponding JDBCDataSourceRuntimeMBean.
Which two statements are true regarding the impact on the application that is using that data source? (Choose two.)

• A. The shutdown() operation will fail if there are any reserved connections in use.
• B. The forceShutdown() operation will allow 20 seconds for any reserved connections in use to complete prior to destroying the connection.
• C. The shutdown() operation will send an HTTP 503 status code to clients.
• D. The forceShutdown() operation will immediately cause any in-flight transaction to be rolled back.
• E. The shutdown() operation will allow 20 seconds for any reserved connections in use to complete, otherwise the operation will fail.

Answer: AD

Explanation:
A: When you shut down a data source (not forcibly shut down), WebLogic Server closes database connections in the data source and shuts down the data source. If any connections from the data source are currently in use, the operation will fail.
D: When you forcibly shut down a data source, WebLogic Server closes database connections in the data source and shuts down the data source. All current connection users are forcibly disconnected.

NEW QUESTION 6

• A. listen port number of individual dynamic servers
• B. machine name that hosts a dynamic server
• C. dynamic server name
• D. replication groups
• E. No parameters can be modifie

Answer: E

Explanation:
A dynamic server is a server instance that has not been individually configured but instead gets its configuration from a server template.

NEW QUESTION 7
Your clients are connected to distributed destinations to consume messages sent to various JMS topics.
Recently, JMS connections got interrupted due to a network failure and your clients dropped their connections as well. How would you ensure seamless failover for your clients when a distributed destination fails? (Choose the best answer.)

• A. No action should be needed at the client’s level if the failover is being handled properly at the cluster level.
• B. Set the 1ientReconnectOptions parameter to Automatic in the Administration Console under the destination configuration general page.
• C. Implement an automatic reconnect mechanism in the client exception handler.
• D. Set AutomaticClientReconnect to Enabled in the Administration Console under the destination configuration general page.

Answer: C

Explanation:
A simple way to failover a client connected to a failed distributed destination is to write reconnect logic in the client code to connect to the distributed destination after catching onException.

NEW QUESTION 8
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.)

NEW QUESTION 9
You are implementing leasing functionality within your environment to ensure exclusive ownership of a cluster-wide entity.
Which type of leasing requires that Node Manager is configured and running? (Choose the best answer.)

• A. high-availability database leasing
• B. high-consensus leasing
• C. non-database consensus leasing
• D. high-availability in-memory leasing

Answer: C

Explanation:
Setting Migration Basis to Consensus leasing means that the member servers maintain leasing information in-memory, which removes the requirement of having a high-availability database to use leasing. This version of leasing requires that you use Node Manager to control servers within the cluster.

NEW QUESTION 10
A current production WebLogic Server (WLS) domain needs to be upgraded without affecting the users. What are the five steps to follow for a Rolling Update? (Choose five.)

• A. Back up the contents of your domain.
• B. Use pack and unpack to upgrade each of the servers in the machine.
• C. Shut down the servers in a single machine.
• D. Repeat the process for all machines in the domain.
• E. Restart the servers in the machine.
• F. Repeat the process for all domains in the machine.
• G. Upgrade the servers in the machin

Answer: ACDEG

Explanation:
A: Before you begin the upgrade process, make sure that you take any necessary precautions such as:
* Back up your applications, database schema, other application data, and domains.
* If required, obtain latest third party plug-ins or components that are compatible with required non-Oracle components. For example, Apache Web Server libraries.
CGED: The rolling upgrade process includes stopping the Administration Server, installing the upgrade, restarting the Administration Server, and then doing the same for each Managed Server in the cluster (machine).

NEW QUESTION 11
Your development team has created a GAR deployment that enables Coherence caching for an application. The GAR file is configured to work within both storage-enabled and storage-disabled nodes.
How would you package your GAR as part of the WebLogic Server deployment process for your application? (Choose the best answer.)

• A. as an EAR module on storage-disabled nodes and standalone on storage-enabled nodes
• B. as an EAR module on storage-enabled nodes and standalone on storage-disabled nodes
• C. within a WAR on storage-disabled nodes and within an EAR on storage-enabled nodes
• D. within a WAR on storage-enabled nodes and within an EAR on storage-disabled nodes

Answer: A

Explanation:
Managed Coherence servers are distinguished by their role in the cluster. A best practice is to use different managed server instances (and preferably different WebLogic Server clusters) for each cluster role.
* storage-enabled – a managed Coherence server that is responsible for storing data in the cluster. Coherence applications are packaged as Grid ARchives (GAR) and deployed on storage-enabled managed Coherence servers.
* storage-disabled – a managed Coherence server that is not responsible for storing data and is used to host Coherence applications (cache clients). A Coherence application GAR is packaged within an EAR and deployed on storage-disabled managed Coherence servers.

NEW QUESTION 12
Review the diagram below. It depicts the following:

Assuming the next request for an HTTP session attribute is a new attribute that is not stored in a near-cache, the client’s session attribute is fetched from the remaining storage-enabled server in cluster 2.
Why is the session attribute retrieved from this other server’s cache? (Choose the best answer.)

• A. Coherence*Web stores sessions in a distributed cache on the back end and the request fails over to the new location after partition re-balancing takes place.
• B. Coherence*Web stores sessions in a replicated cache on the back end and the request fails over to the new location automatically.
• C. Coherence*Web stores sessions in a shared disk cache on the back end and Coherence*Web automatically load balances requests.
• D. Coherence*Web stores sessions in a cache that is backed by a database cache loade
• E. The data is fetched from the database and placed into the cache on the new server.

Answer: A

NEW QUESTION 13
I want to configure automatic migration of pinned services from an unhealthy server to another target in the cluster. I wish to configure consensus leasing for this purpose.
Which two statements are true in this scenario? (Choose two.)

• A. Set the cluster “Migration Basis” policy to Consensus.
• B. Migratable server should be associated with a node manager.
• C. Set the server “Migration Basis” policy to Consensus.
• D. A high availability database must be configured to manage consensus leasing informatio

Answer: AC

Explanation:
A: Using the Automatic Migration option requires setting a cluster’s Migration Basis policy to either Database or Consensus leasing.
C: Setting Migration Basis to Consensus leasing means that the member servers maintain leasing information in-memory, which removes the requirement of having a high-availability database to use leasing. This version of leasing requires that you use Node Manager to control servers within the cluster.

NEW QUESTION 14
You are considering targeting your JMS servers to dynamic clusters to benefit from dynamic scaling. However, you have been advised to keep in mind some of the associated limitations.
What are two valid limitations and considerations for clustered JMS services? (Choose two.)

• A. Store-and-Forward agents cannot be targeted to a cluster (dynamic or mixed).
• B. WLST in offline mode does not support the get and set commands to target JMS servers to a dynamic cluster.
• C. A sub-deployment cannot be targeted to a duster.
• D. Targeting a messaging bridge to a dynamic cluster is not supporte

Answer: AD

Explanation:
A: Store-and-Forward (SAF) Agents cannot be targeted to a Dynamic or Mixed cluster. You can target SAF Agents to Configured clusters using the default store.
D: Targeting a messaging bridge to a mixed or dynamic cluster is not supported.

NEW QUESTION 15
I am configuring the security policy for my JMS module. I am specifying some security conditions for the module. Which two security conditions are valid in this context? (Choose two.)

• A. The JMS module can be accessed only between 1 pm and 6 pm.
• B. The JMS module should throw a custom security exception on invalid access.
• C. The JMS module can process only 50 messages at a time.
• D. The JMS module can be accessed only by users belonging to the Operators group.
• E. The JMS module can be accessed in a receive-only mod

Answer: AD

Explanation:
There are two security conditions:
* time-constrained
* By Group or User

NEW QUESTION 16
You have a multithreaded application that looks up the WebLoqic JMS ConnectionFactory object from the JNDI tree. Which statement is correct in this scenario? (Choose the best answer.)

• A. It is not permitte
• B. A multithreaded application cannot access the ConnectionFactory object.
• C. The access to ConnectionFactory object MUST be synchronized.
• D. The ConnectionFactory object can be referenced in a multithreaded application without any special considerations.
• E. Multiple threads trying to use the ConnectionFactory object simultaneously will throw an exception.
• F. In a multithreaded scenario, connection objects cannot be safely created from the ConnectionFactor

Answer: B

Explanation:
A connection factory supports concurrent use, enabling multiple threads to access the object simultaneously.
A session and its message producers and consumers can only be accessed by one thread at a time (i.e. the access must be synchronized). Their behavior is undefined if multiple threads access them simultaneously.

NEW QUESTION 17
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.)

• A. AUTO_ACKNOWLEDGE
• B. CLIENT_ACKNOWLEDGE
• C. DUPS_OK_ACKNOWLEDGE
• D. DEFAULT_ACKNOWLEDGE

Answer: B

Explanation:
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. References:

NEW QUESTION 18
You are creating a Domain Template to simplify the process of deploying a domain across multiple hosts. Which five types of information can be included in a Domain Template? (Choose five.)

• A. domain configuration, those included in the config.xml file
• B. Java Enterprise Edition (Java EE) applications and shared libraries
• C. Windows and UNIX server start scripts
• D. Windows Start menu entries
• E. custom folders and files
• F. LDAP data
• G. JTA log
• H. e-mail notification settings

Answer: ABCDE

Explanation:
A: config.xml and any JDBC and JMS resources defined in config.xml are not displayed in the Current Template View pane by default because the Domain Template Builder automatically includes them in the template when creating the template.
B: The Add or Omit Applications screen is displayed only if applications are included in the template or domain that you selected.
C: When you are creating a template, you want the scripts and files that you are packaging with your template to be free of local domain environment settings and ready for use by the Configuration Wizard. The Domain Template Builder automatically updates any standard scripts included in a template (such as start scripts) by replacing hard-coded values for various domain environment settings with replacement variables.
D: The Specify Start Menu Entries screen prompts you to create items to be added to the Windows Start menu.
E: By default, the Domain Template Builder includes files from the WebLogic domain or template you specified as the source for the new template. If you selected a domain as the source for your new template, some files and directories are included automatically.

NEW QUESTION 19
You are asked to configure Node Manager for your production environment. You are considering whether to use the Java version or the script-based version of Node Manager.
Which statement correctly describes the difference between the two versions?

• A. If you are installing WebLogic Server on a Windows system, you must use the Java version of Node Manager.
• B. The script-based version of Node Manager can be used in conjunction with inetd on supported UNIX systems.
• C. The script-based version of Node Manager requires a larger footprint than the Java version.
• D. When Node Manager is used for consensus leasing, you may see faster performance with the script-based version.

Answer: A

Explanation:
Java-based Node Manager runs within a Java Virtual Machine (JVM) process. It is recommended that you run it as a Windows service on Windows platforms and as an operating system service on UNIX platforms.
For UNIX and Linux systems, WebLogic Server provides a script-based version of Node Manager.
