Question No: 24

When deploying a new edition of an application, which edition rollout configuration option should be used to ensure that the two editions of the application are not active at the same time?

  1. Atomic

  2. Grouped

  3. Soft reset

  4. Hard reset

Answer: A Explanation:

Performing an atomic rollout to an edition replaces an edition on half of the cluster at a time to serve all user requests with a consistent edition of the application. All user requests are served by either the previous or the new edition; user requests are never served by both editions.

An atomic rollout ensures that all application requests are served by a consistent edition, for example, either edition 1.0 or 2.0, but not by both.

Question No: 26

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

  1. The HTTP server plug-in loaded with the embedded HTTP server within the application server forwards the request to the application server.

  2. The plug-in configuration file loaded with the embedded HTTP server within the application server forwards the request to the application server.

  3. The HTTP serverplug-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.

  4. The plug-in configuration file loaded with the HTTP server forwards therequest to the embedded HTTP server within the application server. 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#39;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.

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

  1. The user agent of the browser that hasinitiated the request.

  2. The last time that the component was updated by a code deploy.

  3. The time that the component was started in the application server.

  4. 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:
