A system administrator has just built a WebSphere Application Server node to replace a node lost to disk failure. The system administrator wishes to reincorporate this node into the existing WebSphere Application Server cell and use the prior configuration information. Unfortunately, the backup of the cell is extremely out of date. What should the system administrator use to accomplish this task?

• A. wsimport
• B. manageprofiles
• C. wsadmin
• D. addNode

A system administrator is configuring an IBM WebSphere Application Server cell at a company that has a policy requiringcommunication between web servers and application servers be done via SSL. The cell profiles have been created using the default certificate configurations and leverage the internal deployment manager SSL management. What is required by the web server plugins to ensure SSL communications between web servers and application servers?

• A. A self-signed certificate must be generated using the keytool from the IBM JDK and then added to the web server keyrings.
• B. A signer certificate from a well known public Certificate Authority such as VeriSign for Entrust must be in theweb server keyrings.
• C. The application server signer certificate for each application server must be in the web serverplugin keyrings
• D. The cell root signer certificate must be in the web server plugin keyrings.

A system administrator needs to create a diagnostic trace for an application server which has a problem that occurs only infrequently. The desire is to limit the amount of space taken up by the trace output file but still ensure that the log includes the trace information recorded during the problem. What should the system administrator do to accomplish these goals?

• A. Use the First Failure Data Capture (FFDC)feature to ensure the trace log is only capture on the first instance of the problem.
• B. Limit the Maximum Number of Historical Files to one.
• C. Configure the trace output to use a memory buffer and do a manual dump when the problem occurs.
• D. Reduce the Maximum File Size to an amount just larger than the required trace log.

A system administrator needs to control which staff members have access to manage certain application servers. They choose to use fine grained control and map the staffmembers to only those specific application servers to which they need access. What does the system administrator need to do to accomplish this?

• A. Add custom properties to each of the application servers with role mappings for each staff member
• B. Use anAdministrative Authorization Group to map the staff members and roles to the application servers.
• C. Create a custom user registry which prevents authorization requests to the application servers not in the desired list.
• D. Create a security domain and add the application servers with the staff members in the role definitions.

A system administrator needs to tune the connection pool size parameters fora data source based on the current pool usage and the application server CPU utilization. Which of the following will provide the system administrator a recommendation on the efficient values for pool size?

• A. Performance Monitoring Infrastructure counter for connection pool size
• B. Request Metrics for connection pool size
• C. Performance advisor for connection pool size
• D. Performance Monitoring Infrastructure counter for current pool usage
