Question 11

What must be modified to configure the authentication settings for IIOP requests?

A. Bus security settings
B. J2C authentication settings
C. Session Initiation Protocol (SIP) authentication settings
D. Common Secure Interoperability Version 2 (CSIV2) settings

Correct Answer:D
WebSphere Application Server can propagate attributes directly as part of theCSIv2 protocol for RMI/IIOP requests.

Question 12

Which statement describes the functionality of web containers?

A. Web containers forward EJB requests to the EJB container.
B. Web containers process JSPs, servlets, and various server-side objects.
C. Servlets requests are forwarded from an EJB container to a web container.
D. Each application server cancontain multiple web containers, depending upon the number of JSPs and servlets.

Correct Answer:B
The runtime environment for Web components is called the Web container.. It processes servlets, JSP files, and other types of server-side components.

Question 13

An administrator configures an IBM DB2data source at cell scope. The environment variable DB2UNIVERSAL_JDBC_DRIVER_PATH is configured at cluster scope. The data source test connection on one node succeeds, but fails on the other node with java.lang.ClassNotFoundException:com.ibm.db2.jcc.DB2ConnectionPoolDataSource.
Which of the below is the likely cause for the exception?

A. The data source is configured at cell scope.
B. Multiple driver JARs are installed on the second node.
C. DB2UNIVERSAL_JDBC_DRIVER_PATH is configured at cluster scope.
D. A different version of the JDBC driver JAR does not exist on the second node.

Correct Answer:C
Check that the variable is correctly defined at the scope where the JDBCProvider/DataSource is defined.
Note: At runtime, WebSphere Application Server invokes a physical data source by resolving the appropriate variable at a level where one of thefollowing criteria exists: The scope of the variable can contain the data source configuration; that is, the variable has the larger scope.
The variable and the data source have identical scopes.
Application Server meets these conditions by attempting to resolve the variable at each level of the scope spectrum. That is, the product tries to resolve the variable in the server scope, then the cluster scope, then the node scope, and lastly the cell scope.

Question 14

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.

Correct Answer:AD
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.

Question 15

Which statement is true about a request made from a browser for a jsp running in an application server?

A. The HTTP server plug-in loaded with the embedded HTTP server within the application server forwards the request to the application server.
B. The plug-in configuration file loaded with the embedded HTTP server within the application server forwards the request to the application server.
C. The HTTP serverplug-in loaded with the HTTP server forwards the request to the embedded HTTP server within the application serve
D. The embedded server forwards the request into the web container.
E. The plug-in configuration file loaded with the HTTP server forwards therequest to the embedded HTTP server within the application serve
F. The embedded server forwards the request into the web container.

Correct Answer:A
When IBM HTTP Server receives a request for a JSP file, it passes the request to WebSphere Application Server -Express's servlet engine, which calls the JSP processor. The JSP processor is an internal servlet which converts a JSP file into Java source code and compiles it. The servlet that implements the JSP processor is org.apache.jasper.runtime.JspServlet.
