E. The Node Manager for the Administration Server machine is configured and running.

Answer: B,DExplanation: B: The administration server must be running. Note: A WebLogic Server administration domain is a logically related group of WebLogic Serverresources. Domains include a special WebLogic Server instance called the Administration Server,which is the central point from which you configure and manage all resources in the domain. D: Node Manager is a WebLogic Server utility that enables you to start, shut down, and restartAdministration Server and Managed Server instances from a remote location. Although NodeManager is optional, it is recommended if your WebLogic Server environment hosts applicationswith high availability requirements. A Node Manager process is not associated with a specific WebLogic domain but with a machine.You can use the same Node Manager process to control server instances in any WebLogic Serverdomain, as long as the server instances reside on the same machine as the Node Managerprocess. Node Manager must run on each computer that hosts WebLogic Server instances --whether Administration Server or Managed Server -- that you want to control with Node Manager.

QUESTION NO: 3

Within your data center, the Administration and Managed Servers utilize a shared, central storagedevice, which servers access via NFS.

In this scenario, your application files no longer need to be copied to servers across the network.Which server attribute allows you to override this behavior?

A. Startup Mode B. Staging Mode C. Root Directory D. Listen Address

Answer: BExplanation: The server staging mode specifies the default deployment mode for a server if noneis specified at deployment time. For example, the server staging mode is used if you deploy anapplication or module using weblogic.Deployer and you do not specify a staging mode.

Explanation: A Managed Server is a WebLogic Server instance that runs deployed applications. Itrefers to the Administration Server for all of its configuration and deployment information. Usually,you use Managed Servers to run applications in a production environment.

See step 4 and 5 below in particular:

To use the WebLogic Server scripts to start Managed Servers: See Creating WebLogic Domains Using the ConfigurationWizard or "Create Managed Servers" inthe Administration Console Online Help. where DOMAIN_NAME is the directory in which you located the domain. By default, this directoryis BEA_HOME\user_projects\domains\DOMAIN_NAME. where managed_server_name specifies the name of the Managed Server and admin_url specifies the listen address (host name or IP address) and port number of the domain'sAdministration Server. For example, the following command uses startManagedWebLogic.cmd to start a Managed Servernamed myManagedServer. The listen address for the domain's Administration Serveris AdminHost:7001: c:\bea\user_projects\domains\mydomain\bin\startManagedWebLogic.cmd myManagedServerhttp://AdminHost:7001

QUESTION NO: 12

Consider a single JMS module that includes a connection factory as well as queue.

Based on your systems requirements, the connection factory needs to be made available to allservers in the domain. The queue, on the other hand, can be targeted to only a single JMS serverdomain.

What is the best way to achieve the desired JMS setup?

A. Create two subdeployments within the JMS module. B. Target the JMS server to the JMS module. C. Target the JMS module to the entire domain. D. Replace the queue with a topic.

Answer: AExplanation: A subdeployment is a mechanism by which JMS module resources (such asqueues, topics, and connection factories) are grouped and targeted to a server resource (such asJMS servers, server instances, SAF agents, or a cluster). For example, you can group a connection factory with stand-alone queues or topics in asubdeployment targeted to a specific JMS server, which guarantees that all these resources areco-located to avoid extra network traffic. Another advantage of such a configuration would be if thetargeted JMS server needs to be migrated to another WebLogic server instance, then theconnection factory and all its connections will also migrate along with the JMS server'sdestinations. However, when stand-alone queues or topics are members of a subdeployment, aconnection factory can only be targeted to the same JMS server.

Identify two supported methods of deploying a JMS module to a domain.

A. Create a module by using the administration console. B. Load a module into the WebLogic database. C. Include a module file within a web application archive. D. Include a module file within an enterprise application archive. E. Define a module within an existing JDBC module.

Answer: A,DExplanation: A: Main Steps for Creating Packaged JMS Application Modules Follow these steps to configure a packaged JMS module: If necessary, create a JMS server to target the JMS module to, as explained in "Configure JMSServers" in the Administration Console Online Help. Create a JMS system module and configure the necessary resources, such as queues or topics,as described in "Configure JMS system modules and add JMS resources" in the AdministrationConsole Online Help. The system module is saved in config\jms subdirectory of the domain directory, with a "-jms.xml"suffix. Copy the system module to a new location, and then: Give the module a unique name within the domain namespace. Delete the JNDI-Name attribute to make the module application-scoped to only the application. Add references to the JMS resources in the module to all applicable J2EE applicationcomponent's descriptor files, as described in Referencing a Packaged JMS Application Module InDeployment Descriptor Files. Package all application modules in an EAR, as described in Packaging an Enterprise ApplicationWith a JMS Application Module. Deploy the EAR, as described in Deploying a Packaged JMS Application Module.

Oracle 1z0-102 Exam


D:JMS application modules can be packaged as part of an Enterprise Application Archive (EAR),as a packaged module. Packaged modules are bundled with an EAR or exploded EAR directory,and are referenced in the weblogic-application.xml descriptor. The packaged JMS module is deployed along with the Enterprise Application, and the resourcesdefined in this module can optionally be made available only to the enclosing application (i.e., asan application-scoped resource). Such modules are particularly useful when packaged with EJBs(especially MDBs) or Web Applications that use JMS resources. Using packaged modulesensures that an application always has required resources and simplifies the process of movingthe application into new environments.

Which two statements are true about multicast communication within a cluster?

A. Multicast can be used for cluster heartbeat messages. B. Multicast is used to replicate session state between servers. C. Multiple clusters can share the same multicast address and port. D. You may disable multicast on individual cluster members. E. Multicast traffic is often limited to a single subnet.

Answer: A,EExplanation: A: WebLogic Server instances in a cluster communicate with one another using twobasic network technologies: * IP sockets, which are the conduits for peer-to-peer communication between clustered serverinstances. * IP unicast or multicast, which server instances use to broadcast availability of services andheartbeats that indicate continued availability. E: In many deployments, clustered server instances reside within a single subnet, ensuringmulticast messages are reliably transmitted. However, you may want to distribute a WebLogicServer cluster across multiple subnets in a Wide Area Network (WAN) to increase redundancy, orto distribute clustered server instances over a larger geographical area.

Answer: B,C,EExplanation: B: For efficient security management, BEA recommends adding users to groups. Agroup is a collection of users who usually have something in common, such as working in thesame department in a company.

C: Example of group nesting: Every user is a member of the everyone group. The users group is nested within the everyone group.

E (not A): You can configure more than one security provider of a given type in a security realm.For example, you might use two or more different Role Mapping providers or Authorizationproviders. If you have more than one security provider of the same type in a security realm, theorder in which these providers are called can affect the overall outcome of the security processes.By default, security providers are called in the order that they were added to the realm. You canuse the Administration Console to change the order of the providers.

Note: Security Providers - are modules that provide security service to application to protectWeblogic resource. Types of security providers in WebLogic Server are Authentication Provider, Authorization Provider, Auditing Providers, Credential Mapping Provider,Identity Assertion Provider, Principal Validation Provider, Adjudication Providers, Role MappingProviders, Certificate Lookup and Validation Providers, Keystore Providers and Realm Adapterproviders

Your production JMS server and/or its consumers are not able to handle the incoming messageworkload. The number of messages on the server never stabilizes and the server eventuallybecomes overload.

Which JMS server attribute will best help prevent the JMS server from being overloaded byproducers?

A. Producer Pause High

Oracle 1z0-102 Exam


B. Messages Threshold High C. Reconnect Polity D. Paging Directory E. Pool Maximum Capacity

Answer: BExplanation: JMS Configuration option ' Messages Threshold High': The upper threshold (number of messages stored in this JMS server) that triggers flow control andlogging events. A value of -1 disables the events for this JMS server. If the number of messages exceeds this threshold, the triggered events are: Log Messages - A message is logged on the server indicating a high threshold condition. Flow Control - If flow control is enabled, the JMS server becomes armed and instructs producers to begindecreasing their message flow.

Which three statements are true about WebLogic clusters?

A. Clusters provide clients with transparent failover. B. EJB applications can be targeted to an entire cluster. C. All cluster members must bind to the same port number. D. Cluster members replicate application data by using heartbeats. E. Cluster members can be associated with one or more domains. F. Web applications require a proxy in order to be used in a cluster.

Answer: A,B,CExplanation: A: If an object is clustered, failover and load balancing for that object is available. In a WebLogic Server cluster, application processing can continue when a server instance fails.You cluster application components by deploying them on multiple server instances in theclusterso, if a server instance on which a component is running fails, another server instance onwhich that component is deployed can continue application processing.

The choice to cluster WebLogic Server instances is transparent to application developers andclients.

Your server includes an application that uses a generic JDBC data source to connect to adatabase. However, the network connection between the server and the database is not 100%reliable.

You wish to avoid scenarios in which the application fails due to a failed JDBC connection. Identifytwo data source attributes to help accomplish this.

A. Statement Cache B. Pool Reserve Mode C. Test Table Name D. Test Connection Mode E. Test Connections on Reserve

Answer: A,EExplanation: A: Each connection in a data source has its own individual cache of prepared andcallable statements used on the connection. However, you configure statement cache options perdata source. That is, the statement cache for each connection in a data source uses the statementcache options specified for the data source, but each connection caches it's own statements. E: When Test Connections On Reserve is enabled, when your application requests a connectionfrom the data source, WebLogic Server tests the connection using the query specified in TestTable Name before giving the connection to the application.

Testing reserved connections can cause a delay in satisfying connection requests, but it makessure that the connection is viable when the application gets the connection.

As an Oracle WebLogic Server administrator, you are given an EAR file application to deploy. Identity three reasons for creating an EAR file first.

A. After the .ear file has been deployed, the developer will not have to ask for your assistance todeploy it again. B. The EAR file is created to avoid namespace clashes in the Java code. C. The EAR file can contain multiple WAR, EAR, and other resources to easily bundle together. D. The EAR file is required if you are deploying an application. E. The EAR file can declare application-wide security roles definitions.

Answer: A,B,EExplanation:

E: An EARfile contains: * Web module A WAR file containing the view logics like JSPs, Servlets, Html contents. Every web module musthave one Web Deployment descriptor placed inside WEB-INF/web.xml

web.xml is a J2EE standard deployment descriptor. Among other settings, it has a set of elementsfor configuring security for the web application.

Note: *An EAR file provides a convenient way to bundle up all pieces of a J2EE application. It maycontain Java Module, WAR Module or an EJB Jar module.

Oracle 1z0-102 Exam


An EAR can contain at least any one of these modules. EAR may contain more Modules as well. *To bring your portal online in a production environment, it is first necessary to prepare your portalapplication. Typical preparation steps include modifying deployment descriptors for the product,building the Enterprise archive (EAR) with all its pre-compiled classes, and deciding if you want tocompress that EAR into an archive or leave it exploded.

A managed server, myserver1, has a boot.properties file in the security directory. It was startedwith the startManageWeblogic.sh script(.cmd in windows) and his boot.properties file was used forits startup credentials.

You just used the administration console to change all administrator passwords. To continue usingboot.properties, what can you do?

A. This is not possible. A boot.properties file can be used only with the Administration Server. B. Delete boot.properties. In the administration console, under the myserver configuration, selectGenerate Boot Identity file. C. You need not do anything- The password in boot .properties was automatically updated byadministration console when you changed the password. D. Edit boot.propetties. Type over the encrypted password with the new password in clear text.The next time myserver1 is started, it will encrypt the password in the file. E. Delete boot .properties. Use the WLST encrypt () command to create a new boot.properties filecontaining the new password. Copy that file into the security directory of myserver1

Answer: DExplanation: If you install the WebLogic Server Examples component, the default user weblogicis created that has permission to start and stop WebLogic Server. The default password iswelcome1. If you change the password of the weblogic user, WebLogic Server does notautomatically update this password in the boot.properties file, which is located in theDOMAIN_NAME/servers/AdminServer/security directory.

If you change the password for user weblogic, you can use either of the following workarounds sothat you can continue to boot a WebLogic Server instance via that username and its newpassword:

* Remove the boot.properties file. Subsequently each time you start WebLogic Server, you areprompted for the username and password. The changed password for the weblogic user will beaccepted.

* Modify the existing boot.properties file, changing the username and password as follows:

username=weblogic password=welcome1 Subsequently during the server startup process, the boot.properties file is encrypted again.

A client accesses a web application named companystore that is running on WebLogic Server.After adding several items to the shopping cart, the host server crashes. The client is automaticallyredirected to another server by a proxy, but the shopping cart is now empty.

Which WebLogic Server feature would you enable to remedy this situation?

A. Application Persistence B. Message Persistence C. Session Replication D. Dynamic Failover E. Stateful Pooling

Answer: CExplanation: In order for a cluster to provide high availability it must be able to recover fromservice failures. In clusters that utilize Web servers with WebLogic proxy plug-ins, the proxy plug-in handlesfailover transparently to the client. If a server fails, the plug-in locates the replicated HTTP sessionstate on a secondary server and redirects the client's request accordingly.

In a Development Mode domain, the configuration lock can be acquired automatically. F. Changes must always be activated before they can be undone.

Answer: A,C,FExplanation: A: You can view any changes that you have saved, but not yet activated, by clickingthe View Changes and Restarts link in the Change Center. C: The View Changes and Restarts link presents two tabs, Change List and Restart Checklist:

* The Change List tab presents all changes that have been saved, but not yet activated. * The Restart Checklist lists all servers for which non-dynamic changes have been activated, butwhich require restarts before the changes become effective.

F (not D):As you make configuration changes using the Administration Console, you click Save (orin some cases Finish) on the appropriate pages. This does not cause the changes to take effectimmediately. The changes take effect when you click Activate Changes in the Change Center. Atthat point, the configuration changes are distributed to each of the servers in the domain. If thechanges are acceptable to each of the servers, then they take effect. If any server cannot accept achange, then all of the changes are rolled back from all of the servers in the domain. The changesare left in a pending state; you can then either edit the pending changes to resolve the problem orrevert the pending changes.

Note: To change a production domains configuration, you must:

1. Locate the Change Center in the upper left of the Administration Console screen. 2. Click the Lock & Edit button to lock the configuration edit hierarchy for the domain. 3.

Identify two reasons for defining machines and assigning servers to them in Weblogic Server.

A. A machine can be the proxy to a cluster. B. A machine definition is required to configure the Node Manager. C. To reference an instance of WebLogic Server, you must know its machine and port. D. Machine is a required organizational unit. A domain contains machines and machines containservers. E. WebLogic Server uses server machine assignments to help it choose servers in a cluster onwhich to replicate session state. F. The machine's Cluster Weight attribute may be used by load balancers to help them determinehow often to send requests to servers assigned to that machine.

Answer: B,EExplanation: B: The Administration Server uses the machine definition in conjunction with theNode Manager application to start remote WebLogic Server instances. E: By default, WebLogic Server attempts to create session state replicas on a different machinethan the one that hosts the primary session state. You can further control where secondary statesare placed using replication groups. A replication group is a preferred list of clustered servers to beused for storing session state replicas. Using the WebLogic Server Console, you can define unique machine names that will hostindividual server instances. These machine names can be associated with new WebLogic Serverinstances to identify where the servers reside in your system. Machine names are generally used to indicate servers that run on the same machine.

Which three statements are true about the default behavior of WebLogic Server proxy plug-ins?

A. The proxy will pin a client to a specific server if a session cookie is created. B. The proxy fails over to another server if a connection or request times out. C. The proxy distributes requests to cluster members based on their CPU usage. D. The proxy dynamically learns the latest locations of cluster members. E. The proxy always uses SSL, regardless of the client's protocol. F. The proxy replicates session data to its backup proxy.

Answer: A,B,DExplanation: A: When the HTTP client requests the servlet, HttpClusterServlet proxies therequest to the WebLogic Server cluster. HttpClusterServlet maintains the list of all servers in thecluster, and the load balancing logic to use when accessing the cluster. In the above example,HttpClusterServlet routes the client request to the servlet hosted on WebLogic Server A.WebLogic Server A becomes the primary server hosting the client's servlet session. To provide failover services for the servlet, the primary server replicates the client's servlet session

state to a secondary WebLogic Server in the cluster. This ensures that a replica of the sessionstate exists even if the primary server fails (for example, due to a network failure). In the exampleabove, Server B is selected as the secondary. The servlet page is returned to the client through the HttpClusterServlet, and the client browser isinstructed to write a cookie that lists the primary and secondary locations of the servlet sessionstate. If the client browser does not support cookies, WebLogic Server can use URL rewritinginstead. Figure, Accessing Servlets and JSPs using a Proxy:

B: In clusters that utilize Web servers with WebLogic proxy plug-ins, the proxy plug-in handlesfailover transparently to the client. If a server fails, the plug-in locates the replicated HTTP sessionstate on a secondary server and redirects the client's request accordingly. D: The WebLogic proxy plug-in maintains a list of WebLogic Server instances that host a clusteredservlet or JSP, and forwards HTTP requests to those instances on a round-robin basis.

You are logged in to the administration console for a domain that is running in Development Mode.The domain configuration, you select Production Mode, Save, and then Activate Changes. Whichtwo statements are true?

A. All running servers must be restarted. B. Only the Administration Server must be restarted. C. Auto-deployment will no longer be available for this domain. D. This change may be made only through the Administration Server's secure port. E. If you decide to go back to Development Mode, uncheck Production Mode in the administrateconsole.

Answer: A,EExplanation: All servers in a domain run either in development mode or production mode. To configure all servers in a domain to run in production mode:

1. If you have not already done so, in the Change Center of the Administration Console, click Lock& Edit . In the left pane of the Console, under Domain Structure, select the domain name. 2. Select Configuration > General and select the Production Mode check box. 3. Click Save, and then, to activate these changes, in the Change Center, click Activate Changes. 4. Shut down any servers that are currently running. 5. Invoke the domain's startWebLogic script. The Administration Server starts in the new mode. 6. If the domain contains Managed Servers, start the Managed Servers. Result

As each Managed Server starts, it refers to the mode of the Administration Server to determine itsruntime mode.

Note: Once you have changed to production mode, whether by using a start command argument,the Console, or WLST, you cannot change back to development mode without restarting theserver.

You use a web browser to log in to a web application that is deployed to WebLogic Server. Whenyou click link named "publish" on the site, an "Access Denied" message appears.

Which two statements must be true about this server's security configuration?

A. The application is not associated with any security roles. B. Multiple security realms are active at the same time. C. Your user account is a member of a group. D. Your user account exists in an authentication provider. E. A security policy is attached to the "publish" link URL.

Answer: D,EExplanation: D: You were able to log in to the web application that is deployed throughWebLogic. In WebLogic Server, Authentication providers are used to prove the identity of users or systemprocesses. This implies that your account exists in an authentication provider. E: Extra security is needed to use the publish link. This could be explained by a security policyattached the publish Link URL.

You have set Server log Rotation criteria to either size or time. When a domain is in ProductionMode, which statement is true?

A. Log files are rotated when the server restarts. B. Log files are not rotated in Production Mode. C. Log files are rotated only when the rotation criteria are met. D. Log files are rotated when the rotation criteria are met or rotated when the server restarts

Answer: CExplanation: By default, when you start a server instance in production mode, the server rotatesits local log file whenever the file grows to 5000 kilobytes in size. It does not rotate the local serverlog file when you start the server.

You can change these default settings for log file rotation. For example, you can change the filesize at which the server rotates the log file or you can configure a server to rotate log files basedon a time interval. You can also specify the maximum number of rotated files that can accumulate.After the number of log files reaches this number, subsequent file rotations delete the oldest logfile and create a new log file with the latest suffix.

Which three methods does WebLogic provide to implement persistent JMS messaging?

A. Create a file store and assign it to a JMS server. B. Create a JDBC store and assign it to a JMS server. C. Configure a file store within a JMS module. D. Configure the domain's default store. E. Use the target server's default store.

Answer: A,B,EExplanation: A: The main steps for creating a custom file store are as follows:

1.Create a directory where the file stores data will be persisted. 2.Create a custom file store and specify the directory location that you created. 3.Associate the custom file store with the subsystem(s) or migratable target that will be accessing

Oracle 1z0-102 Exam


it, such as: *For JMS servers, select the custom file store on the General Configuration page. *For Store-and-Forward agents, select the custom file store on the General Configuration page. *For a Path Service, select the custom file store on the General Configuration page.

B: The main steps for creating a JDBC store are as follows:

Create a JDBC data source or multi data source to interface with the JDBC store. Create a JDBC store and associate it with the JDBC data source or multi data source. It is highly recommended that you configure the Prefix option to a unique value for each configuredJDBC store table. Associate the JDBC store with the subsystem(s) that will be using it, such as: For JMS servers, select the JDBC store on the General Configuration page. For Store-and-Forward agents, select the JDBC store on the General Configuration page. For a Path Service, select the custom file store on the General Configuration page.

E:Each server instance, including the administration server, has a default persistent store thatrequires no configuration.

Note: When a persistent message is sent, it is stored in the WebLogic Persistent Store. The persistent store provides a built-in, high-performance storage solution for WebLogic Serversubsystems and services that require persistence. For example, it can store persistent JMSmessages or temporarily store messages sent using the Store-and-Forward feature. Thepersistent store supports persistence to a file-based store or to a JDBC-enabled database.

Note 2: A persistent message is guaranteed to be delivered once-and-only-once. The messagecannot be lost due to a JMS provider failure and it must not be delivered twice. It is not consideredsent until it has been safely written to a file or database. WebLogic JMS writes persistentmessages to a WebLogic persistent store (disk-base file or JDBC-accessible database) that isoptionally targeted by each JMS server during configuration.

Managed Server Independence enabled is not selected in the configuration of myserver1. Whichstatement is true?

Oracle 1z0-102 Exam


A. Only the Node Manager can start myserver1 B. Only a local start script can start myserver1 C. Myserver1 cannot be part of a cluster. D. The Administration Server must be available before starting myserver1

Answer: DExplanation: To prevent the Administration Server from becoming a single point of failure,Managed Servers can always function without the presence a running Administration Server.When a Managed Server starts, it contacts the Administration Server to retrieve its configurationinformation. If a Managed Server is unable to connect to the specified Administration Serverduring startup, it can retrieve its configuration directly by reading a copy of the config.xml file andother files located on the Managed Server's own file system. A Managed Server that starts in this way is running in Managed Server Independence mode. Inthis mode, a server uses cached application files to deploy the applications that are targeted to theserver.
