    The correct answer is 7001. This is the default port used for the Oracle Weblogic Administration console. The Administration console is a web-based interface used to manage and monitor the Weblogic server. By default, it is accessed using the URL http://localhost:7001/console.

    Rate this question:

  • 3. 

    Which of the following URL's can be used to access a Weblogic Administration Console

    • A.

      Http://hostname:console

    • B.

      Http://port:hostname:console

    • C.

      Http://hostname:port/console

    • D.

      Http://console:port/hostname

    Correct Answer
    C. Http://hostname:port/console
    Explanation
    The correct answer is http://hostname:port/console. This is because the Weblogic Administration Console can be accessed using the URL format http://hostname:port/console, where "hostname" refers to the name of the server hosting Weblogic, and "port" refers to the port number on which Weblogic is running.

    Weblogic is an Oracle technology that requires to properly work a Java installation

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Weblogic is an application server developed by Oracle. It is built using Java and requires a Java installation in order to function properly. This is because Weblogic is written in Java and relies on the Java Virtual Machine (JVM) to execute its code. Therefore, it is true that Weblogic requires a Java installation to work correctly.

    Rate this question:

  • 7. 

    Two benefits of Weblogic Clustering are:

    • A.

      Scalability

    • B.

      High Availability

    • C.

      SSL Certificates install

    Correct Answer(s)
    A. Scalability
    B. High Availability
    Explanation
    Weblogic Clustering provides two main benefits: scalability and high availability. Scalability refers to the ability of the system to handle increased workload by distributing it across multiple servers, thus improving performance and accommodating more users. High availability ensures that the system remains accessible and operational even in the event of server failures, by automatically redirecting requests to other available servers. These benefits make Weblogic Clustering a reliable solution for large-scale applications that require both scalability and high availability. The mention of SSL Certificates install in the options is irrelevant and does not relate to the benefits of Weblogic Clustering.

    Rate this question:

  • 8. 

    In Weblogic, what type of Objects can be clustered:

    • A.

      Node Manager

    • B.

      JMS Destinations

    • C.

      JDBC Connections

    Correct Answer(s)
    B. JMS Destinations
    C. JDBC Connections
    Explanation
    Weblogic allows for the clustering of JMS Destinations and JDBC Connections. Clustering JMS Destinations enables load balancing and failover capabilities for messaging services, ensuring high availability and scalability. Clustering JDBC Connections allows multiple instances of an application to share the same database connection pool, improving performance and resource utilization. Node Manager, on the other hand, is not an object that can be clustered in Weblogic. It is a separate component responsible for starting, stopping, and monitoring managed servers in a Weblogic domain.

    Correct Answer(s)
    A. Administration Console
    B. WLST (Weblogic Scripting Tool)
    C. Configuration Template Builder
    Explanation
    The correct answer is a list of management utilities available in Weblogic. These utilities include the Administration Console, which provides a web-based interface for managing and configuring Weblogic Server; WLST (Weblogic Scripting Tool), which allows administrators to automate tasks using a command-line scripting language; and the Configuration Template Builder, which is used to create reusable configuration templates for Weblogic Server deployments. These utilities offer different ways for administrators to manage and configure their Weblogic environments.

    A Managed Server is a WebLogic Server instance that runs deployed applications

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    A Managed Server is indeed a WebLogic Server instance that runs deployed applications. This means that it is responsible for executing and managing the applications that have been deployed on it. It is a component of the WebLogic Server architecture and is used to distribute the workload and provide high availability for the applications.

  • 12. 

    What are the key capabilities of a Weblogic Cluster?

    • A.

      Application Failover

    • B.

      Automatic and Manual migration of instances

    • C.

      Load Balacing

    Correct Answer(s)
    A. Application Failover
    B. Automatic and Manual migration of instances
    C. Load Balacing
    Explanation
    A Weblogic Cluster has three key capabilities: application failover, automatic and manual migration of instances, and load balancing. Application failover ensures that if one instance of an application fails, another instance will take over to ensure uninterrupted service. Automatic and manual migration of instances allows for the movement of instances between servers, either automatically or manually, to optimize resource usage and performance. Load balancing distributes incoming requests across multiple instances to evenly distribute the workload and prevent overload on any single instance. These capabilities are essential for ensuring high availability, performance, and scalability in a Weblogic Cluster.

      Enterprise Applications

    • B.

      Web Applications

    • C.

      Enterprise JavaBean

    Correct Answer(s)
    A. Enterprise Applications
    B. Web Applications
    C. Enterprise JavaBean
    Explanation
    WebLogic supports three types of deployment units: Enterprise Applications, Web Applications, and Enterprise JavaBeans. An Enterprise Application is a collection of components, such as web modules and EJB modules, packaged together as a single unit for deployment. Web Applications are standalone applications that consist of web components, such as HTML, JSP, and servlets. Enterprise JavaBeans (EJB) are server-side components that encapsulate the business logic of an application. These three types of deployment units allow developers to deploy different types of applications on the WebLogic server.

      Project

    • B.

      Instance

    • C.

      Domain

    Correct Answer
    C. Domain
    Explanation
    A logical related group of Weblogic server resources is known as a domain. A domain in Weblogic consists of a group of servers or instances, which are managed collectively. It is a logical entity that represents a Weblogic server configuration and includes various resources such as applications, services, and data sources. The domain provides a centralized management point for these resources and allows for easy administration and deployment of applications within the Weblogic server environment.

    All servers within a cluster must be at the same service pack level in Weblogic

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    In a cluster environment, all servers must be at the same service pack level in Weblogic to ensure compatibility and consistency. This is important because different service pack levels may introduce different features, bug fixes, or updates that can impact the functioning of the cluster. Having all servers at the same service pack level ensures that they are all running on the same codebase and have the same capabilities, minimizing any potential issues or discrepancies within the cluster. Therefore, the statement "All servers within a cluster must be at the same service pack level in Weblogic" is true.
