Identify three reasons that explain why assigning more than one managed serve achieve better performance than running one managed server with more resources?
Correct Answer: C,E,F
Explanation/Reference:
Note:
* Two or more Managed Servers can be configured as a WebLogic Server cluster to increase application scalability and availability. In a WebLogic Server cluster, most resources and services are deployed identically to each Managed Server (as opposed to a single Managed Server), enabling failover and load balancing. A single domain can contain multiple WebLogic Server clusters, as well as multiple Managed Servers that are not configured as clusters. The key difference between clustered and non-clustered Managed Servers is support for failover and load balancing. These features are available only in a cluster of Managed Servers.
* A WebLogic Server cluster provides these benefits:
Scalability
The capacity of an application deployed on a WebLogic Server cluster can be increased dynamically to meet demand. You can add server instances to a cluster without interruption of service-the application continues to run without impact to clients and end users.
High-Availability
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 the cluster-so, if a server instance on which a component is running fails, another server instance on which that component is deployed can continue application processing.
