2. By running a system job that cleans the files as needed
3. By configuring the ExceptionFileMaximumAge property in ffdcRun.properties
4. By configuring the TimesToDump property in ffdcStop.properties

Answer: C

QUESTION 83
In order to gather all of the necessary data required by IBM Support to troubleshoot a database connection pooling problem, an administrator should perform which task(s)?

1. Run the collector command, use the problemType option to specify database connection pooling and submit the resulting JAR file to IBM Support
2. Use the Service component of the IBM Support Assistant (ISA) to gather data for the database connection pooling problem type
3. Reproduce the problem, create a JAR  file including the System.log and native_stdout.log files then submit the JAR file to IBM Support
4. Reproduce the problem, use the Tivoli Performance Viewer to log the JDBC connection pool activity then submit the log file to IBM Support

Answer: B

QUESTION 84
What is the advantage of implementinga multi-tiered environments across multiple machines?

1. It can more closely align with a customer’s business functions (i.e. distribution, ordering, and inventory management.)
2. The tiers allow you to tune individual products
3. It is the separation of tiers that allows operating system tuning parameters to be used based on the machine’s function
4. Separation reduces maintenance complexities since components are highly available in a distributed configuration

Answer: C

QUESTION 85
A WAR file containing several JSR 168 compliant portlets has been successfully installed in an application server. If portlet serving has been enabled, how can the portlets be accessed with a browser?

3. the deployment manager

Answer: C

QUESTION 87
Which statement is NOT true about the Session Initiation Protocol (SIP) container?

1. The servlet container provides the network services over which requests and responses are received and sent.
2. A SIP servlet container manages the network listener points on which it listens for incoming SIP traffic.
3. The SIP servlet container can employ a SIP proxy server to route, load balance, and improve response times between SIP requests and back-end SIP container resources.
4. The SIP servlet container can directly interact with other SIP servlet container in the cell to co-ordinate SIP servlet requests.
5. The SIP servlet container decides which appliations to invoke and in what order. The container also contains and manages servlets through their life cycle.
