NEW QUESTION 3
An administrator configures an IBM DB2data source at cell scope. The environment variable DB2UNIVERSAL_JDBC_DRIVER_PATH is configured at cluster scope. The data source test connection on one node succeeds, but fails on the other node with java.lang.ClassNotFoundException:com.ibm.db2.jcc.DB2ConnectionPoolDataSource.
Which of the below is the likely cause for the exception?

• A. The data source is configured at cell scope.
• B. Multiple driver JARs are installed on the second node.
• C. DB2UNIVERSAL_JDBC_DRIVER_PATH is configured at cluster scope.
• D. A different version of the JDBC driver JAR does not exist on the second node.

Answer: C

Explanation:
Check that the variable is correctly defined at the scope where the JDBCProvider/DataSource is defined.
Note: At runtime, WebSphere Application Server invokes a physical data source by resolving the appropriate variable at a level where one of thefollowing criteria exists: The scope of the variable can contain the data source configuration; that is, the variable has the larger scope.
The variable and the data source have identical scopes.
Application Server meets these conditions by attempting to resolve the variable at each level of the scope spectrum. That is, the product tries to resolve the variable in the server scope, then the cluster scope, then the node scope, and lastly the cell scope.

NEW QUESTION 5
What is one of the benefits of using a federated repository over a user registry?

• A. Does notsupport identity profiles
• B. Supports only one registry in a realm
• C. Supports multiple registries within a realm
• D. Provides account and password policy support

Answer: C

Explanation:
Federated repositories enable you to use multiple repositories with WebSphere® Application Server. These repositories, which can be file-based repositories, LDAP repositories, or a sub-tree of an LDAP repository, are defined and theoretically combined under a single realm. All of the user repositories that are configured under the federated repository functionality are invisible to WebSphere Application Server.

NEW QUESTION 7
An administrator has deployed an application that uses 30 unique SQL statements with a maximum data source connection pool size of 10.
What is the recommended prepared statement cache size for the application?

• A. 10
• B. 30
• C. 40
• D. 300

Answer: B

Explanation:
To determine the highest value for your cache size to avoid any cache discards, add the number of uniquely prepared statements and callable statements, as determined by the SQL string, concurrency, and the scroll type, for each application that uses this data source on a particular server. This value is the maximum number of possible statements that can be cached on a given connection over the life of the server. Setting the cache size to this value means that you never have cache discards. In general, configure a larger cache for applications with a greater number of statements.

NEW QUESTION 10
What data source property can an administrator configure to minimize the chances of encountering StaleConnectionExceptions?

• A. Minimum connections = 0
• B. Reap Timeout < Unused Timeout
• C. Purge Policy = FailingConnectionOnly
• D. Unused Timeout > Half firewall timeout

Answer: A

Explanation:
The configuration options below help minimize the chances of encounteringStaleConnectionExceptions by helping to ensure that your WebSphere Application Server maintains control of database connections, specifically, the only one closing them, rather than other components in your network:
The datasource MIN connections should beset to 0. By setting a MIN > 0, you are telling
the application server that this number of connections will be valid for the life of the application server JVM. Unless you can guarantee the MIN number of connections will never be timed out or dropped, setting a MIN will cause a StaleConnectionException when the connection becomes invalid.

NEW QUESTION 20
An administrator notices that the Message Driven Beans (MDBs) are slow to complete, and decides to increase the ‘Maximum concurrent MDB invocations per endpoint’.
Which thread pool should be tuned to ensure it can run the maximum number of MDBs without waiting?

• A. Default
• B. WebContainer
• C. SIBJMSRAThreadPool
• D. WMQJCAResourceAdapter

Answer: D

Explanation:
The thread pool WMQJCAResourceAdapter is referenced by the WebSphere MQ (WMQ) resource adapter inbound delivery to MDB's. When WebSphere MQ resource adapter is used in conjunction with the activation specs, the resource adapter's Work Manager uses the values defined for the WMQJCAResourceAdapter for utilizing the total number of threads defined.
Ideally the default values provides for the WMQJCAResourceAdapter will be sufficient for the resource adapter. But in case there is an heavy load on the system processing huge
number of messages, you can increase the maximum number of threads the thread pool can hold.

NEW QUESTION 21
Assuming there are no custom properties defined in current plugin-cfg.xml file, what should be done before running the GenPluginCfg command?

• A. Delete the globalplugin-cfg.xmlin the<profile_root>/config/cellsdirectory.
• B. Delete the currentplugin-cfg.xmlin the<profile_root>/config/cellsdirectory.
• C. CleartheEnable automated web server configuration processingoption in the web server plugin configuration service.
• D. Use either the Integrated Solutions Console or theConfigurewebServerDefinition.jaclscript to create a web server definition.

Answer: B

Explanation:
Delete the plugin-cfg.xml file in the profile_root/config/cells directory before you use
theGenPluginCfgcommand. Otherwise, configuration changes do not persist to the plugin- cfg.xml file. However, do not delete the plugin-cfg.xml file if you have custom properties that you previously set in it that you need to persist.
Note:You can update the global plugin-cfg.xml file using the administrative console or running the GenPluginCfg command for all of the clusters in a cell. However, you must delete the config/cells/plugin-cfg.xml file before you update the global plugin-cfg.xml file. If you do not delete the config/cells/plugin-cfg.xml file, only the new properties and their values are added to the global plugin-cfg.xml file. Any updates to existing plug-in property values are not added to the global plugin-cfg.xml file.
