• Question 51:

  A performance test team was testing the capacity of concurrent users of a web application deployed on a multi-processor server. While testing 250 concurrent users, the administrator discovers connections to the database are failing. In response, a system administrator increased the connection pool to the maximum limit which the database allows and increased the prepared statement cache size. The test passed, but the application response time was slower. How should the system administrator tune the data source properties to improve the application response time?

  A. Change connection pools purge policy.
  B. Decrease connection pool reap time.
  C. Decrease number of free pool partitions.
  D. Decrease the prepared statement cache size.
  A. Change connection pools purge policy.

  B. Invoke wsadmin with the argument-profileName globalScript.py.
  C. Modify the configureCustomProperty script to import globalScript. py.

• Question 54:

  A system administrator decides to use the advice from the Performance and Diagnostic Advisor to identify the optimum connection pool settings for data sources. In a cell, the data source db2datasource is defined under node scope and used

  by two servers from that node. The administrator receives two different sets of advice for db2datasource.

  . One set of advice suggests to increase the maximum connection pool size for db2datasource. . The other suggests reducing the maximum connection pool size for db2datasource.

  How should the administrator configure the data sources before reusing the Performance and Diagnostic Advisor?

  A. Create a data source of the same name under cell scope.
  B. Create a data source of the same name under server scope for each server.
  C. Increase the minimum connection pool size for the data source.
  D. Decrease the maximum connection pool size for the data source.
  B. Create a data source of the same name under server scope for each server.

• Question 55:

  A WebSphere Application Server cell was configured with a deployment manager node and a custom node. An operator manually changed some configuration files in the custom node, and the node became out of synch with the master

  repository.

  The system administrator used the Synchronize button in the system administration session of the Integrated Solutions Console (ISC) to try to resynchronize the node, but the node remained out of sync.

  What should the administrator do to fix it?

  A. Use the Full Resynchronize button.
  B. Invoke "sync" operation on NodeSync MBean.
  C. Recreate the custom profile with the same name without deleting the node.
  D. Manually copy all the deployment manager configuration files to the custom node.
  A. Use the Full Resynchronize button.

• Question 56:

  In a test environment, a system administrator has configured an external HTTP server in the DMZ that is routing to a cluster of application servers. The administrator wants to achieve higher performance when routing and prioritizing incoming requests to the back-end cluster.

  How can the system administrator achieve this task?

  A. Configure a cluster of external HTTP servers.
  B. Enable the prefer local option on the cluster members.
  C. Set up a Caching Proxy server between the external web server and the application server.
  D. Place an On Demand Router (ODR) between the external web server and the application servers.
  D. Place an On Demand Router (ODR) between the external web server and the application servers.

• Question 57:

  After installing an enhanced EAR in a WebSphere Application Server environment, a system administrator with Configurator privileges is able to see a JDBC provider and a data source in the Integrated Solution Console (ISC) but is not able to delete these resources.

  How can the administrator resolve this issue?

  A. Use the AdminTask object to delete the resources.
  B. Stop all application server instances and then delete the resources.
  C. Ask another administrator with iscadmin privilege to delete the resource.
  D. Edit the EAR to remove the application scoped resources and reinstall the application.
  A. Use the AdminTask object to delete the resources.

• Question 58:

  A system administrator needs to set a new Liberty profile environment to support an application.

  What should the administrator do to enable this environment for high availability and scalability of the application?

  A. Define multiple server members in one collective controller.
  B. Define multiple servers in a cluster in one collective controller.
  C. Define multiple collective controllers within a Liberty collective.
  D. Define multiple server members in multiple collective controllers.
  C. Define multiple collective controllers within a Liberty collective.

• Question 59:

  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. A Liberty collective environment with autonomic managers and on demand router (ODR).
  B. A flexible management environment supported by one admin agent running in each cell.
  C. A dynamic cluster with autonomic managers, application placement controller and intelligent routers.
  D. A heterogeneous cell with enough servers to support the peak load spread across multiple nodes on the same machine.
  C. A dynamic cluster with autonomic managers, application placement controller and intelligent routers.

• Question 60:

  A system administrator has created a cluster containing two servers in a same node. The administrator did not select the option Generate unique HTTP ports during the creation of the cluster members. After the cluster creation, the administrator changed the HTTP port of the second cluster member to 9081.

  Testing the servers using the snoop servlet directly to the server's HTTP port, the administrator got the following error message for the second server; SRVE0255E: A WebGroup/Virtual Host to handle server2:9081 has not been defined

  How can the administrator fix this problem?
