Two benefits of Weblogic Clustering are:
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.
8.
In Weblogic, what type of Objects can be clustered:
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.

12.
What are the key capabilities of a Weblogic Cluster?
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.
13.
Weblogic Support the following types of deployment units
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.
14.
A logical related group of Weblogic sever resources is known as:
Correct Answer
