Examine the domain diagram:

Assume all servers are running and you have an online WLST session connected to the administration server.
Select two code options that would set the variable x as a reference to the machine02 configuration MBean. (Choose two.)

• A. cd(‘/Machines/machine02’)x = cmo
• B. x = getMBean(“/Machines/machine02”)
• C. x = cmo.getRef(‘/Machines/machine02’)
• D. getRef(“/Machines/machine02”)x = cmo.currentObj()
• E. cmo.getMBean(‘/Machines/machine02’)x = cmo.currObj()
• F. cd(‘/Machines/machine02’)x = getRef(cmo)
• G. x = getConfiguration(‘/Machines/machine02’)

Answer: AB

Explanation:
A: WLST online provides a variable, cmo, that represents the current management object. Example: wls:/mydomain/serverConfig/Servers/myserver/Log/myserver> cmo[MBeanServerInvocationHandler]mydomain:Name=myserver,Server=myserver,Type=
Log
B: wls:/mydomain/edit !> bean=getMBean('Servers/myserver/WebServer/myserver') wls:/mydomain/edit !> print bean [MBeanServerInvocationHandler]mydomain:Name=myserver,Type=WebServer,Server=my server

NEW QUESTION 2
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 3
You have enabled JMS Diagnostic Logging and are analyzing JMS Message delivery and acknowledgment using the generated log entries. For this purpose, you are tracking individual message IDs.
What is the default format of the message ID that you would expect to see in the log? (Choose the best answer.)

• A. Hexadecimal (e.g., 0xCAE987A401)
• B. Numeric (e.g., 9018199222001)
• C. Floating Point (e.g., 10029920902.10111)
• D. Doubly dot delimited (e.g., 683871.11228587923566.0)

Answer: D

Explanation:
Example: <ID:<327315.1116014813453.0>>

NEW QUESTION 4
Your organization is using a Multi data source (MDS) on WebLogic Server to support applications connecting to an Oracle RAC database. You have been tasked with configuring a new callback handler for the MDS.
Which two statements are true concerning related MDS options and behavior? (Choose two.)

• A. Callback handlers are optional when using the Failover MDS Algorithm.
• B. If the Failover Callback Handler attribute is set on the MDS, the Test Frequency attribute is no longer used.
• C. Callback handlers are called for both failover and failback decisions.
• D. You can register only one callback handler for each WebLogic serve

Answer: CD

Explanation:
C: A callback handler used to control the failover and failback within a multi data source must include an implementation of the weblogic.jdbc.extensions.ConnectionPoolFailoverCallback interface.
D: You can register a callback handler with WebLogic Server that controls when a multi data source with the Failover algorithm fails over connection requests from one JDBC data source in the multi data source to the next data source in the list.

NEW QUESTION 5
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?

• A. SRANDBY
• B. ACTIVE
• C. STUCK
• D. RUNNING
• E. WAITING
• F. ADMIN
• G. FAILED

Answer: C

Explanation:
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

NEW QUESTION 6
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 7
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 8
You are configuring the principals needed to fulfill the security requirements of an application within a sandbox environment that uses the WebLogic Server-embedded LDAP server.
The given security requirements provided have outlined the following facts about some test principals:

One security requirement states that internal patient data can be viewed only by physicians who are employees. What is an appropriate way to fulfill this security requirement from a principal perspective using the provided information?

• A. Create an authorization policy that grants access if a user is a member of the physicians group and their employee attribute is true,bypassing the use of a role entirely.
• B. Create an ACL that grants access if a user is a member of the physicians group and their employee attribute is true,bypassing the use of a role entirely.
• C. Create authorization policies for individual users whose employee attribute is true creating a constraint-only model,bypassing the use of a role entirely.
• D. Create an authorization policy that denies access if a user is a member of the physicians group and their employee attribute is false,bypassing the use of a role entirely.

Answer: B

Explanation:
Security policies replace access control lists (ACLs) and answer the question "Who has access to a WebLogic resource?". You assign security policies to any of the defined WebLogic resources (for example, an EJB resource or a JNDI resource)
or to attributes or operations of a particular instance of a WebLogic resource (an EJB method or a servlet within a Web application). If you assign a security policy to a type of WebLogic resource, all new instances of that resource inherit that security policy. Security policies assigned to individual resources or attributes override security policies assigned to a type of WebLogic resource.

NEW QUESTION 9

• 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 12
You need to make sure that a JMS Message never expires.
What value should you set for the JMSExpiration header? (Choose the best answer.)

• A. 999
• B. 1000
• C. 1

Answer: A

Explanation:
WebLogic JMS calculates the JMSExpiration value as the sum of the application's time-to-live and the current GMT. If the application specifies time-to-live as 0, JMSExpiration is set to 0, which means the message never expires.

NEW QUESTION 13
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

Answer: ACD

Explanation:
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.

NEW QUESTION 14

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
Which three statements correctly describe a relationship between Node Manager and Administration Server? (Choose three.)

• A. An Administration Server can be under Node Manager control: You can start it, monitor it, and restart it using Node Manager.
• B. An Administration Server can be a Node Manager client: When you start or stop Managed Servers from the Administration Console, you are accessing Node Manager using the Administration Server.
• C. An Administration Server supports the process of starting up a Managed Server with Node Manager: When you start a Managed Server with Node Manager, the Managed Server contacts the Administration Server to obtain outstanding configuration updates.
• D. By default, the Administration Server starts a Node Manager with the startNM script in the domain’s bin folder.
• E. By default, the Administration Server starts a Node Manager with the startNodeManager script in the domain’s config folder.
• F. Node Manager requires an Administration Server to be running before it can start any Managed Servers.
• G. A Node Manager can be a client of an Administration Server – When Node Manager needs to monitor Managed Servers, it uses the Administration Server’s runtime MBeans.

Answer: BEF

Explanation:
B: If you run Node Manager on a machine that hosts Managed Servers, you can start and stop the Managed Servers remotely using the Administration Console or from the
command line.
E: Although running Node Manager as an operating system service is recommended, you can also start Node Manager manually at the command prompt or with a script. Use startNodeManager.cmd on Windows systems and startNodeManager.sh on UNIX systems.
F: Requests from the Administration Console (or JMX utilities such as weblogic.Admin) to start a Managed Server using Node Manager are issued to the Administration Server for the domain that contains the Managed Server. The Administration Server dispatches the start command to the Node Manager process on the machine that hosts the target Managed Server. Node Manager executes the start command and creates a Managed Server process.

NEW QUESTION 16

NEW QUESTION 19
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 bod

Answer: A

NEW QUESTION 20
What are two differences between a group and a role? (Choose two.)

• A. Groups are static and roles are dynamic and conditional.
• B. Roles can be scoped to applications and groups are only global.
• C. Roles are static and groups are dynamic and conditional.
• D. Groups can be scoped to applications and roles are only global.
• E. Groups can contain roles but roles cannot contain group

Answer: AB

Explanation:
A security role is a privilege granted to users or groups based on specific conditions. Like groups, security roles allow you to restrict access to WebLogic resources for several users at once. Security roles differ from groups as follows:
* Security roles are computed and granted to users or groups dynamically, based on conditions such as user name, group membership, or the time of day. Groups are static.
* Security roles can be scoped to specific WebLogic resources within a single application in a WebLogic Server domain (unlike groups, which are always scoped to an entire WebLogic Server domain).
