NEW QUESTION 7
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.

NEW QUESTION 12
What determines which On Demand Routers (ODRs) a Web server forwards requests to?

• A. The default order in theODR_Module_Routing_Poilicy.xml.
• B. The configuration scope determines which ODRs are included inhttpd.conf.
• C. The configuration scope determines which ODRs are included inplugin-cfg.xml.
• D. The configuration scope determines which ODRs are included inHTTPplugin-cfg.xml.

Answer: C

Explanation:
In a topology with a web server which forwards requests to an on demand router (ODR), the ODR can be set to dynamically generate and update the web server plug-in configuration file plugin-cfg.xml. By configuring an ODR to dynamically update plugin- cfg.xml, you avoid manually updating the file during administrative actions, which can affect the content.

NEW QUESTION 13
When installing IBM WebSphere Application Server on a network file system, IBM Installation Manager fails with an insufficient disk space error.
How could this be resolved?

• A. Increase disk space and try again.
• B. Delete temporary files and try again.
• C. Reboot operating system and try again.
• D. Disable disk space checking inthe config.ini and try again.

Answer: D

Explanation:
On some network file systems, disk space might not be reported correctly at times; and you
might need to bypass disk-space checking and proceed with your installation.
To disable disk-space checking, specify the following system property in the config.ini file in IM_install_root/eclipse/configuration and restart Installation Manager.

• C. Map a security role to the user/group for the application using the Integrated Solutions Console, save changes, and restart the application.
• D. Map a security role to the user runAs roles for the application using the Integrated Solutions Console, save changes, and restart the application.

Answer: C

Explanation:
WSRR defines J2EE roles that must be mapped to user or group principals. This can be done by using the WebSphere Administration Console

• B. AdminTask
• C. AdminConfig
• D. AdminControl

Answer: D

Explanation:
You can use the wsadmin tool to stop applications.

NEW QUESTION 16
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.

• A. Place the file in the monitored directory.
• B. Place the file in the operating system defined temporary directory.
• C. Place the file in the operating system defined user home directory for the user that owns the Java process.
• D. Email the file to wasadmin@hostname.com, where hotname.com is the host of the IBM WebSphere Application Server.

Answer: A

Explanation:
You can install an enterprise application fileon an application server or cluster by dragging or copying an enterprise archive (EAR), web application archive (WAR), Java archive (JAR), or Session Initiation Protocol (SIP) archive (SAR) to a monitored directory.

NEW QUESTION 18
In an IBM WebSphere Application Server cluster, an administrator notices EJB requests are not evenly distributed on the cluster members during the load test.
What two things can the administrator verify in order to identify and resolve the issue? (Select two.)

• A. Ensure Dynamic Workload Management is enabled.
• B. Ensure host scoped routing optimization is enabled.
• C. Ensure PMI Workload Management counters are enabled.
• D. Ensure each server in the cluster has an equal weighted value.
• E. Ensure the Web server plug-in is using the round robin algorithm.

Answer: AD

Explanation:
A: Workload management optimizes the distribution of client processing tasks. Incoming work requests are distributed to the application servers, enterprise beans, servlets, and other objects that can most effectively process the requests.
D: The server weighted round robin routing policy ensures a balanced routing distribution based on the set of server weights that have been assigned to the members of a cluster. For example, if all servers in the cluster have the same weight, the expected distribution for the cluster is that all servers receive the same number of requests. If the weights for the servers are not equal, the distribution mechanism sends more requests to the higher weight value servers than the lower weight value servers. The policy ensures the distribution that you want, based on the weights that are assigned to the cluster members.
