Question 2
What data source property can an administrator configure to minimize the chances of encountering StaleConnectionExceptions? 
  1. Minimum connections = 0
  2. Reap Timeout < Unused Timeout
  3. Purge Policy = FailingConnectionOnly
  4. Unused Timeout > Half firewall timeout
Correct answer: A
Explanation:
The configuration options below help minimize the chances of encountering StaleConnectionExceptions 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 be set 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. References: https://www.ibm.com/developerworks/community/blogs/aimsupport/entry/websphere_application_server_staleconnectionexceptions?lang=en

Question 7
How can an administrator configure Web services security? 
  1. Customize WS-Security policy set and bindings and attach to Web services.
  2. Configure global security with LDAP authentication and map the configuration to Web services.
  3. Request application developer to use Web Services Security API to achieve Web services security.
  4. Enable the Web Services Metadata Exchange (WS-MetadataExchange) protocol to enable message-level security.
Correct answer: C
Explanation:
The Web Services Security specification provides a flexible framework for building secure web services to implement message content integrity and confidentiality. The Web Services Security service programming model supports this flexible framework by providing extension points to integrate new token formats, and methods to obtains keys needed for message protection. The application server programming model provides Web Services Security programming application programming interfaces (WSS API) for securing SOAP messages. Note: WS-Security is a message-level standard that is based on securing SOAP messages through XML digital signature, confidentiality through XML encryption, and credential propagation through security tokens. The Web services security specification defines the facilities for protecting the integrity and confidentiality of a message and provides mechanisms for associating security-related claims with the message. References: https://www.ibm.com/support/knowledgecenter/en/SSAW57_8.5.5/com.ibm.websphere.nd.doc/ae/container_wssec_top.html

Question 8
When installing a new application to IBM WebSphere Application Server, which location is valid for the application file?
  1. Client Machine
  2. Managed Node
  3. Unmanaged Node
  4. Remote Web Server
Correct answer: B
Explanation:
Configuration file location during application installation Several things occur upon installation of an application onto WebSphere Application Server:The application binaries and deployment descriptors are stored within the master repository. The application binaries and deployment descriptors are published to each node that will host the application. These files are stored in the local copy of the repository on each node. Each node then installs the applications that are ready for execution by exploding the EARs under profile_root/installedApps/cell_name/, as follows:- profile_root/installedApps/cell_name/ This directory contains a subdirectory for each application deployed to the local node. - profile_root/installedApps/cell_name/app_name.ear/ Each application-specific directory contains the contents of the original EAR used to install the application. Note: A node is a logical grouping of managed servers. Nodes can be managed or unmanaged. An unmanaged node does not have a node agent or administrative agent to manage its servers, whereas a managed node does. Both application servers and supported web servers can be on unmanaged or managed nodes. References: WebSphere Application Server V8.5, July 2013, page 17

Question 9
An administrator is using the Guided Troubleshooter in the IBM Support Assistant to troubleshoot IBM WebSphere Application Server issues. After going through data collection and analysis, no reliable solution is found. 
What is the administrator’s best next step?
  1. Call in a new PMR with IBM and upload Troubleshooter data to ECuREP.
  2. Open a new PMR with IBM and upload SystemOut.log from the IBM WebSphere Application Server.
  3. Submit results to the IBM WebSphere Application Server forum for a quick response from other forum users.
  4. Use the Guided Troubleshooter to open a service request with IBM, so all the troubleshooting data analyzed so far is uploaded automatically. 
Correct answer: D
Question 10
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?
  1. Increase disk space and try again.
  2. Delete temporary files and try again.
  3. Reboot operating system and try again.
  4. Disable disk space checking in the config.ini and try again.
Correct 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. References: https://www.ibm.com/support/knowledgecenter/SSEQTP_9.0.0/com.ibm.websphere.installation.base.doc/ae/tins_troubleshoot.html
