Which one of the following options describes the runtime flow starting from the client browser in a clustered WebSphere Application Server Network Deployment topology?
A system administrator has configured a cluster containing 40 servers. The cluster members all belong to one core group. While examining the log files, the administrator notices that the core group coordinator is consuming abnormally high amounts of memory and CPU resources.
How can the system administrator reduce the memory and CPU resource usage of the core group coordinator?
Remember that coordinator election occurs whenever the view changes. Electing a new coordinator uses a lot of resources because this process causes increased network traffic and CPU consumption. Specifying a preferred coordinator server, whenever practical, helps eliminate the need to make frequent coordinator changes.
A system administrator has to design a new production environment to host a web application. The workload of this web application is expected to increase during special marketing campaigns.
Which one of the following topologies should the administrator configure to address the requirements for this new environment?
A dynamic cluster is a server cluster that uses weights and workload management to balance the workloads of its cluster members dynamically, based on performance information that is collected from the cluster members. Dynamic clusters enable application server virtualization.
A dynamic cluster is an application deployment target that can expand and contract depending on the workload in your environment. Dynamic clusters work with autonomic managers, including the application placement controller and the dynamic workload manager to maximize the use of your computing resources. Dynamic clusters are required for many of the Intelligent Management autonomic functions, including high availability and service policies.

An application contains a web services client and the application is deployed and running. A system administrator has to add a response timeout to the deployed web services client, so the call fails in a timely fashion.
Which artifact should the administrator use?
The ibm-webservicesclient-bnd.xmi deployment descriptor file contains information for the web services run time that is WebSphere product-specific. This deployment descriptor file is used with Java API for XML-based web services.
