Oracle WebLogic Server 12c Essentials

Question No: 11

Which two statements are true regarding the WebLogic domain?

  1. A WebLogic domain can have more than one Administration server.

  2. A WebLogic domain has at least one WebLogic server.

  3. A WebLogic domain can have at the most one cluster.

  4. A WebLogic domain can cross multiple physical machines.

  5. Each WebLogic domain is associated with a different Node Manager.

Answer: B,D

Explanation: B: A domain consists of one or more WebLogic Server instances (and their associated resources) that you manage with a single Administration Server.

D: In a domain, server instances other than the Administration Server are referred to as Managed Servers. Managed Servers host the components and associated resources that constitute your applications.


Not A: Each WebLogic Server domain must have one server instance that acts as the Administration Server.

Not C: A domain can include multiple WebLogic Server clusters and non-clustered WebLogic Server instances.

Not E: 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 Server domain, as long as the server instances reside on the same machine as the Node Manager process. 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: 12

When you use WebLogic Management Pack EE, which three operations are enabled compared to managing WebLogic Server only through web console?

  1. management of many WebLogic Server Domains from a single web console

  2. tracking changes in the configuration of WebLogic Domain

  3. automation of provisioning process in the new environment

  4. checking compliance with the licenses that a customer has

  5. visual creation of JDBC DataSource object to Oracle RAC

Answer: A,B,E

Explanation: The WebLogic Server Management Pack EE greatly improves application performance by providing unique functionality to automatically detect performance bottlenecks; quickly diagnose these performance problems, and identify their root cause. Key application performance management features of the pack include the following:

  • (A) Manage multiple farms and WebLogic Domains centrally

  • Monitor Oracle Coherence Cluster – including all nodes within a cluster, all caches, services, connection managers and connections

  • Monitor middleware availability and performance out-of-box; track such data historically, and receive notifications of potential problems

  • Obtain real-time, in-depth JVM diagnostics without instrumentation overhead

  • Trace transactions across containers as well as to the database

  • (E) Analyze call paths and dependencies via graphical, architecture views

  • (E) Automatically discover and model dependencies between Java components, frameworks, and web services

    Question No: 13

    Which three scenarios are true about Domains?

    1. Domains can be created using the Configuration Wizard.

    2. Domains can be created using WLST.

    3. Domain configuration files are located in the WebLogic home directory.

    4. Domains can be created based on a domain template.

    Answer: A,B,D

    Explanation: A: a WebLogic domain can be created by using the Configuration Wizard in graphical mode.

    B: WLST enables you to create a new domain or update an existing domain

    D: A domain template is a JAR file that contains domain configuration documents, applications, security data, startup scripts, and other information needed to create a domain.

    Question No: 14

    A WebLogic team is developing an enterprise application from their desktop WebLogic environment. All development systems are connected to the same eight data sources for testing.

    As a WebLogic Administrator supporting this team, which two actions should you perform to free the developers from creating and configuring all the data sources on their desktop WebLogic environment?

    1. Provide the team with a WebLogic domain template with the testing data sources configured.

    2. Provide the development team with a preconfigured domain archive file.

    3. Provide the development team with the [datasource] -jdbc.xml file to overwrite their local copy.

    4. Create the data sources on behalf each of the developer.

    5. Provide the development team with WLST scripts to create and configure the testing data sources.

    Answer: E

    Explanation: WebLogic Administrators typically use the Administration Console or the WebLogic Scripting Tool (WLST) to create and deploy (target) JDBC modules.


    • (not A) Domain template-defines the full set of resources within a domain, including infrastructure components, applications, services, security options, and general environment and operating system options.

    • Extension template-defines the applications and services that you can add to an existing domain, including product component functionality and resources such as JDBC or JMS.

    • (not B) Each domain describes its configuration in an XML document that is located in the domain’s configuration directory. At run time, each WebLogic Server instance in a given domain creates an in-memory representation of the configuration described in this document.

      The central configuration file for a domain is DOMAIN_NAME/config/config.xml. This file

      specifies the name of the domain and the configuration of each server instance, cluster, resource, and service in the domain. The file includes references to additional XML files that are stored in subdirectories of theDOMAIN_NAME/config directory. These included files are used to describe major subsystems of WebLogic Server.

      Question No: 15

      Which two options best describe how the Maven Plugin for WebLogic enables WebLogic to be effectively used in a Continuous Integration environment?

      1. execution of unit and integration tests

      2. management of the life cycle of a WebLogic domain including creation, configuration, and server life-cycle management

      3. deployment and undeployment of applications

      4. Java profiling

      Answer: A,C Explanation: Note:

    • Apache Maven is a software tool for building and managing Java-based projects. WebLogic Server provides support for Maven through the provisioning of plug-ins that enable you to perform various operations on WebLogic Server from within a Maven environment.

    • Continuous Integration is a software engineering practice which attempts to improve quality and reduce time to deliver software by applying small, frequent quality control efforts. It is characterized by these key practices:

    Use of a version control system

    All developers commit to the ‘HEAD’ (main code line) every day The product is built on every commit

    The build must be automated and fast

    Automated deployment to a production-like environment Automated testing

    Results of all builds are published (so everyone can see who broke the build) Deliverables are easily available (for developers, testers, other stakeholders)

    Question No: 16

    A customer has a development environment that uses the auto-deployment feature. The customer claims the application is not redeployed even if the new version is copied to an application subdirectory. Which two parameters of the configuration should you check?

    1. Check if archive file in the compressed version has a new REDEPLOY file.

    2. If server was started in the Development Mode. Auto-deployment is not supported in production mode.

    3. If the application includes an EJB 3 module. Auto-deployment is not supported for EJBs.

    4. You change JVM from HotSpot to JRockit. Auto-deployment is not supported in HotSpot auto deployment.

    5. If the domain is a single-server domain. Auto-deployment is not supported in multiserver domains.

    Answer: B,E

    Explanation: Auto-deployment is intended for use with a single server target in a development environment.


    • If auto-deployment is enabled, when an application is copied into the \autodeploy directory of the Administration Server, the Administration Server detects the presence of the new application and deploys it automatically (if the Administration Server is running). If WebLogic Server is not running when you copy the application to the \autodeploy directory, the application is deployed the next time the WebLogic Server Administration Server is started. Auto-deployment deploys only to the Administration Server.

    • Limitations of Auto-Deployment

    Auto-deployed applications are very convenient in a development environment, but there are some limitations:

    There is no configuration in config.xml for an auto-deployed application. Therefore, in the Administration Console, there are no notes or target pages associated with an auto-

    deployed application because there is no backing configuration for that information.

    You cannot associate an auto-deployed application with a deployment plan since auto- deployed applications do not support any configuration operations which would be reflected in a deployment plan.

    You cannot set up security policies or roles for auto-deployed applications.

    You cannot undeploy or redeploy auto-deployed applications using WebLogic Server tools.

    Question No: 17

    WebLogic Node Manager can be used to manage the life cycle of WebLogic servers. WebLogic Node Manager is installed and started .

    1. Per Machine

    2. Per Domain

    3. Per Managed Server

    4. Per Admin Server

    Answer: A

    Explanation: 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 Server domain, as long as the server instances reside on the same machine as the Node Manager process. 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: 18

    A customer has a Stock Watch application that publishes stock recommendations to different customers and programs. The stock recommendation message should be processed by only one of the JMS Servers in the cluster. Which JMS model should be used?

    1. JMS Queue

    2. Distributed JMS Queue

    3. Uniform Distributed Topic

    4. Partitioned Distributed Topic

    Answer: A

    Explanation: JMS queue

    A staging area that contains messages that have been sent and are waiting to be read. Note that, contrary to what the name queue suggests, messages don#39;t have to be delivered in the order sent. A JMS queue only guarantees that each message is processed only once.


    Not B: (Only one queue required)

    • 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.

    • A distributed queue is a set of physical JMS queue members. As such, a distributed queue can be used to create a QueueSender, QueueReceiver, and a QueueBrowser. The fact that a distributed queue represents multiple physical queues is mostly transparent to your application.

      Not Topic: JMS topic

      A distribution mechanism for publishing messages that are delivered to multiple subscribers.

      Question No: 19

      Identify the two options that can be used to patch WebLogic Server without Incurring application downtime.

      1. automated process using the Admin Server

      2. automated using JDeveloper

      3. manual process with or without Smart Update

      4. scripted with WLST

      5. automated process using Enterprise Manager 12c

      Answer: C,D Explanation:


    • Rolling Upgrade is the process of upgrading a running WebLogic Server cluster with a patch, maintenance pack, or minor release without shutting down the entire cluster or domain. During the rolling upgrade of a cluster, each server in the cluster is individually upgraded and restarted while the other servers in the cluster continue to host your application.

    Question No: 20

    You want to use WLST to view metrics for a running domain. Which command should you issue to navigate through the Mbean hierarchy containing the metrics?

    1. runtime ()

    2. runtimeMbeanServer ()

    3. connectRuntime ()

    4. beginRuntime ()

    5. serverRuntime ()

    Answer: E

    Explanation: Similar to the configuration information, WebLogic Server runtime MBeans are arranged in a hierarchical data structure. When connected to an Administration Server, you access the runtime MBean hierarchy by entering the serverRuntime or the domainRuntime command. The serverRuntime command places WLST at the root of the server runtime management objects, ServerRuntimeMBean; the domainRuntime command, at the root of the domain-wide runtime management objects, DomainRuntimeMBean.
