Question: 185
What is a benefit of using the IBM Extended Cache Monitor? A . It invalidates cacheids.
B . It displays the contents of the cache instances.
C . It displays the contents of object cache instances.
D . It displays the dependency ids of the cache instances.
Answer: C Explanation:
The IBM Extended Cache Monitor for IBM WebSphere Application Server provides you with two functions that are not available with the cache monitor that is supplied with WebSphere Application Server. These two functions enable you to:
display the contents of object cache instances
display the Dynamic Cache mbean statistics for cache instances References:https://www.ibm.com/developerworks/websphere/downloads/cache_monitor.html Question: 186
Which two methods are used for communicating session linkages between the client and the server? (Select two.) A . Cookies
B . LTPA Token C . Rest Services
D . URL Rewriting
E . HTTP Response codes
Answer: C,E Explanation:
Representational State Transfer (REST) is a lightweight framework for designing applications that use HTTP to make calls. REST uses HTTP to perform the Create, Read, Update, and Delete (CRUD) operations between client and server. Applications interactwith the services by using
HTTP, POST, PUT, GET, and DELETE operations. References:https://www.ibm.com/support/knowledgecenter/en/SSZLC2_7.0.0/com.ibm.commerce.webservices.doc/concepts/cwvrest.htm Question: 187
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.
Question: 188
How can an administrator deploy or update an EAR, JAR, WAR, or SAR file to an application server or cluster in a development environment?
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 [email protected], 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.
Question: 189
What does the CDcom.ibm.webshpere.alarmthreadmonitor.generate.javacore JVM argument do? A . Creates a javacore dump when a thread is hung
B . Generates a Tracemessage that a javacore should be generated
C . Generates a SystemOut message that a javacore should be generated
D . Allows the administrator to choose whether or not to generate a javacore when a hang is detected
Answer: A Explanation:
If you want to monitor the activity of threads on which system alarms execute, add the following JVM generic arguments to the server settings.
-Dcom.ibm.websphere.alarmthreadmonitor.generate.javacore
Set to any value to cause a javacore dump to be created when an hung system alarm threadis detected. The threads section of the javacore dump can be analyzed to determine what the reported thread and other related threads are doing.
Question: 190
Which statement describes the capabilities of the deployment manager? A . Logical grouping of application servers
B . Created and installed when a node is federated into acell
C . Created automatically when an application server is federated into a cell D . Manages nodes, node agents, and the configuration repository for the cell
Answer: D Explanation:
The deployment manager is an administration application that runs in a special application server, which is created when you install the WebSphere Application Server Network Deployment product or when you create a management profile using the deployment manager profile template.
Question: 191
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.
Question: 192
Which of the following is required for Secure Sockets Layer (SSL) enablement within an HTTP server? A . AJDK
B . A valid, issued certificate
C . IPv6 (Internet Protocol Version 6)
D . Updating thehttps.conffile and not thehttpd.conffile
Answer: B Explanation:
The iKeyman GUI, which is included within the IBM HTTP Server distribution, can be used to create a key database file (for example: key.kdb) needed to store personal server certificates required by the client browser during an SSL handshake.
Question: 193
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.

Question: 194
What is one way to determine if administrative security for IBM WebSphere Application Server is disabled when logging into the Integrated Solutions Console?

B . An administrator is allowed to type any random password.
C . An administrator is prompted for user name, but not password.
D . When the username wasadmin is used to log in, the password used is the default “password”.
Answer: C Explanation:
Congratulations! You have successfully manually disabled Global Security for your IBM WebSphere Application Server instance. You should now be able to access the WAS Integrated Solutions Console (ISC) without having to specify a password.

Answer: C Explanation:
You can use the following different configurations of the application server to combine the plug-in configuration files of multiple application server profiles into a single output file:
* Using multiple stand-alone base application server profiles with an administrative agent using the job manager. The job manager function is a part of WebSphere Application Server Network Deployment. However, you can use the job manager function with stand-alone, base application server profiles. Usethis topic to complete this configuration.
