Question: 1

A system administrator needs to configure a JDBC provider and a data source for an application in a clustered environment. The administrator also needs to copy the JDBC drivers from the database server to the application server machines.

How can the administrator meet these requirements?

ACreate a JDBC provider and the data source in the cluster scope.Copy the driver to all nodes.Set the environment variable at the node level to the driver's path.

BCreate a JDBC provider in the server scope and the data source in the node scope.Copy the driver to all application servers.Set the environment variable at the node level to the driver's path.

CCreate a JDBC provider in the node scope and the data source in the cell scope.Copy the driver to the deployment manager.Set the environment variable at the server level to point to the deployment manager path.

DCreate a JDBC provider in the application scope and the data source in the server scope.Copy the driver to all application server directories.Set the environment variable in each JVM to the driver's path.

Question: 3

While monitoring a cluster in the cell, the administrator notices that one server in the cluster periodically loses connections to the database. When this happens, requests to the server have a significantly decreased response time and various error conditions are listed in the log files for the server. Since the error codes are returned quickly, the server starts returning responses faster than the average service times for the application. Due to this, the weight for the server is increased and a large percentage of incoming requests are being routed to the erroneous server and the server is getting overloaded with requests.

How can the administrator detect these conditions in the future and take action to prevent this problem?

AConfigure the storm drain health policy.

BConfigure the on demand router (ODR) transport chain to tune inbound connections.

CMonitor the JVM heap usage to determine a new server weight.

DEnable the PMI Extended statistic set and use the Connection Pool summary report.

Question: 5

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 --connType RMI --f 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:

Asas.client.props file.

Bssl.client.props file.

Csoap.client.props file.

Dwsadmin.properties file.
