NEW QUESTION 2
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.

Answer: A

Explanation:
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.

NEW QUESTION 8
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.

Answer: C

Explanation:
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.

NEW QUESTION 9
When installing a new application to IBM WebSphere Application Server, which location is valid for the application file?

• A. Client Machine
• B. Managed Node
• C. Unmanaged Node
• D. Remote Web Server

Answer: B

Explanation:
Configuration file location during application installation
Several things occur upon installation of an application onto WebSphere Application Server:
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.

NEW QUESTION 10
Which of the following statements is true regarding the relationship of nodes and node groups?

• A. Nodes can belong to only one node group.
• B. Nodes managed by a node group cannot be deleted.
• C. All nodes are initially not associated with a node group.
• D. All nodes are initially associated with a default node group.

Answer: D

Explanation:
D: a node must be a member ofa node group. Initially, all Application Server nodes are members of the default DefaultNodeGroup node group.
Note:A node group is a collection of managed nodes.

NEW QUESTION 11
An administrator has deployed an application that uses 30 unique SQL statements with a maximum data source connection pool size of 10.
What is the recommended prepared statement cache size for the application?

• A. 10
• B. 30
• C. 40
• D. 300

Answer: B

Explanation:
To determine the highest value for your cache size to avoid any cache discards, add the number of uniquely prepared statements and callable statements, as determined by the SQL string, concurrency, and the scroll type, for each application that uses this data source on a particular server. This value is the maximum number of possible statements that can be cached on a given connection over the life of the server. Setting the cache size to this value means that you never have cache discards. In general, configure a larger cache for applications with a greater number of statements.

NEW QUESTION 12
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.

NEW QUESTION 15
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.

Answer: AD

Explanation:
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.

In addition to logging changes, what can Cross Component Trace capture?

• A. The user agent of the browser that hasinitiated the request.
• B. The last time that the component was updated by a code deploy.
• C. The time that the component was started in the application server.
• D. Data snapshots that store entire request and response bodies on the file system.

Answer: C

Explanation:
Cross Component Trace (XCT) annotates the logs so that log entries that are related to a request that is serviced by more than one thread, process, or even server are identified as belonging to the same unit of work.
XCT log records are typically added to the logs to:

NEW QUESTION 19
Through what protocol can a Java client directly access EJBs running on an application server?

• A. JDBC
• B. RMI/IIOP
• C. SOAP/JMS
• D. SOAP/HTTP

Answer: D

Explanation:
Provided that it uses the correct protocols (SOAP, HTTP, WSDL), any web service client can access a stateless session bean, whether ornot the client is written in the Java programming language. The client doesn’t even “know” what technology implements the service: stateless session bean, JAX-WS, or some other technology. In addition, enterprise beans and web components can be clients ofweb services. This flexibility enables you to integrate Java EE applications with web services.

NEW QUESTION 20
How can an administrator configure Web services security?

• A. Customize WS-Security policy set and bindings and attach to Web services.
• B. Configure global security with LDAP authentication and map the configuration to Web services.
• C. Request application developer to use Web Services Security API to achieve Web services security.
• D. Enable the Web ServicesMetadata Exchange (WS-MetadataExchange) protocol to enable message-level security.

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 withthe message.
