A system administrator discovers an issue that requires a change to a federated server. In this cell, WebSphere administrative security is enabled, but application security is not enabled.
How should the administrator make this change?
The administrator should use:
- A . a web browser to connect to the node agent https port.
- B . a web browser to connect to the deployment manager admin_host port.
- C . the job manager to submit a job to update the unmanaged server.
- D . an ssh connection to the node and modify the client_types.xml file.
A system administrator has created a Jython script that will run in WebSphere Network cell where administrative security is enabled.
This script is named doUpdate.py and will be run by using the following:
wsadmin CconnType RMI Cf doUpdate.py
How can the administrator suppress a user/password prompt from appearing when this script is run?
Set the user and password in the:
- A . sas.client.props file.
- B . ssl.client.props file.
- C . soap.client.props file.
- D . wsadmin.properties file.
A system administrator wants to learn some of the Jython scripting commands for the administration of the environment.
Which product feature should the administrator use?
- A . The wsadmin.properties file to load a profile.
- B . The AdminTask object to generate wsadmin scripts.
- C . The guided activities panel from the Integrated Solutions Console (ISC).
- D . The “Log command assistance commands” option in the Integrated Solutions Console (ISC).
Within a WebSphere Application Server Network Deployment cell, a system administrator needs to write a script to determine if a particular server is stopped. It is important that the wsadmin script explicitly return a status of stopped as opposed to just failing.
What wsadmin object should the administrator use to write this script?
- A . AdminApp
- B . AdminTask
- C . AdminConfig
- D . AdminControl
A system administrator is tasked with monitoring the overall health of the WebSphere environment to be able to tune the environment properly.
Specifically, the administrator was asked to:
Which PMI modules can the administrator examine to obtain this data?
- A . Number of requests, Java virtual memory, Average response time
- B . Number of requests, Average response time, Web server thread pools
- C . Average response time, Java virtual memory, Number of Live HTTP Sessions
- D . Average response time, Web server thread pools, Number of Live HTTP Sessions
A system administrator is required to create a star topology for multi-cell performance management for three WebSphere Application Server cells.
How should the administrator configure the Application Placement Controller (APC) in a star topology?
Configure the cell custom property CenterCell to:
- A . false in all three WebSphere Application Server cells.
- B . false in one WebSphere Application Server celltrue in the other two WebSphere Application Server cells.
- C . true in all three WebSphere Application Server cells.
- D . true in one WebSphere Application Server cellfalse in the other two WebSphere Application Server cells.
A system administrator has deployed web applications to a clustered environment where database session persistence is configured. The administrator needs to improve the response time and the throughput.
How can the system administrator do this?
- A . Disable server affinity.
- B . Configure dynamic caching.
- C . Configure a load balancer to spread work between existing web servers.
- D . Tune the database session persistence to optimize for failover.
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.
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.
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.
