• Question 43:

  Which two methods are used for communicating session linkages between the client and the server? (Choose two.)

  A. Cookies
  B. LTPA Token
  C. Rest Services
  D. URL Rewriting
  E. HTTP Response codes
  C. Rest Services
  E. HTTP Response codes

  ---

  Representational State Transfer (REST) is a lightweight framework for designing applications that use HTTP to make calls. REST uses HTTP to perform the Create, Read, Update, and Delete (CRUD) operations between client and server. Applications interact with the services by using HTTP, POST, PUT, GET, and DELETE operations.

• Question 44:

  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.
  D. All nodes are initially associated with a default node group.

  ---

  D: a node must be a member of a 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.

  Incorrect Answers:

  A: A node can be a member of more than one node group.

  C: A node must be a member of a node group. Initially, all Application Server nodes are members of the default DefaultNodeGroup node group.

• Question 45:

  Which of the following gives clues when comparing traces from different processes and correlating events of different servers in the same data center?

  A. Thread ID
  B. Timestamp
  C. Message ID
  D. Exception from top of stack trace
  B. Timestamp

  ---

  Reading a Trace File Timestamps give good clues: Time stamps are real machine time values Good when comparing traces from different processes

• Question 46:

  An administrator needs to resolve port conflicts after creating a managed node using the Profile Management Tool. Which supported method can be used to resolve the port conflicts?

  A. Edit serverindex.xml.
  B. Use updatePorts.ant.
  C. Use Profile Port Checker tool and set ports.
  D. Use manageProfile tool and set port range on the profile.
  B. Use updatePorts.ant.

  ---

  If you discover ports conflicts, then you can reassign ports manually. To reassign ports, run the updatePorts.ant file by using the ws_ant script. Reference: https://www.ibm.com/support/knowledgecenter/en/SSEQTP_8.5.5/com.ibm.websphere.base.doc/ae/tpro_instancessaappserv.html

• Question 47:

  An administrator notices that the Message Driven Beans (MDBs) are slow to complete, and decides to increase the `Maximum concurrent MDB invocations per endpoint'. Which thread pool should be tuned to ensure it can run the maximum number of MDBs without waiting?

  A. Default
  B. WebContainer
  C. SIBJMSRAThreadPool
  D. WMQJCAResourceAdapter
  D. WMQJCAResourceAdapter

  ---

  The thread pool WMQJCAResourceAdapter is referenced by the WebSphere MQ (WMQ) resource adapter inbound delivery to MDB's. When WebSphere MQ resource adapter is used in conjunction with the activation specs, the resource adapter's Work Manager uses the values defined for the WMQJCAResourceAdapter for utilizing the total number of threads defined.

  Ideally the default values provides for the WMQJCAResourceAdapter will be sufficient for the resource adapter. But in case there is an heavy load on the system processing huge number of messages, you can increase the maximum number of threads the thread pool can hold.

• Question 48:

  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 server plug-in loaded with the HTTP server forwards the request to the embedded HTTP server within the application server. The embedded server forwards the request into the web container.
  D. The plug-in configuration file loaded with the HTTP server forwards the request to the embedded HTTP server within the application server. The embedded server forwards the request into the web container.
  A. The HTTP server plug-in loaded with the embedded HTTP server within the application server forwards the request to the application server.

  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.

• Question 49:

  Which of the following is a potential consequence when using an external session management store over a server level store?

  A. A server level store makes a smaller footprint.
  B. Only half the current sessions can be saved externally.
  C. External session management stores can use additional system resources.
  D. Using an external session management store takes 10X as long to rebuild the session after a failure.
  C. External session management stores can use additional system resources.

  ---

  External session management stores can use additional system resources.

• Question 50:

  A system administrator has downloaded IBM WebSphere Application Server binaries and created a local IBM Installation Manager repository. What can the system administrator do to ensure only this local Installation Manager repository is used during installation of the product?

  A. Create a preference for the public repository.
  B. Use the Packaging Utility to create the repository.
  C. Make sure the metadata for the repository includes the value "local".
  D. Clear the Search service repositories during installation and update option.
