After reading the documentation of that web application, you discover that the WAR file contains a useful tag library that you want to reuse in your own webapp packaged as a WAR file.
                                          What do you need to do to reuse this tag library?

                                          A) Unpack the legacy WAR file, move the TLD file to the META-INF directory, move the class files to the top-level directory, repackage the whole thing as a JAR file, and place that JAR file in your webapp's library directory.
                                          B) Simply rename the legacy WAR file as a JAR file and place it in your webapp's library directory.
                                          C) Unpack the legacy WAR file, move the TLD file to the META-INF directory, repackage the whole thing as a JAR file, and place that JAR file in your webapp's library directory.
                                          D) Unpack the legacy WAR file, move the TLD file to the META-INF directory, move the class files to the top-level directory, repackage the WAR, and place that WAR file in your webapp's WEB-INF directory.

                                          102.
                                          <!--a correct url-pattern and http-method goes here-->

                                          <role-name>SALES</role-name>
                                          105.

                                          If the two security constraints have the same url-pattern and http-method, which two, inserted independently at line 109, will allow users with role names of either SALES or MARKETING to access this resource? (Choose two.)

                                          Guys, come on! This is so little to pay for this 1Z0-858 exam questions, and it is valid. I passed the exam with it on this Tuesday. Very valid!
