質問 3：
Which of the following would be a security and performance best practice for portlets, widgets, and web applications built with IBM Web Experience Factory?
A. Validating all user input data on the server-side only, for best protection against malicious users.
B. Validating all user input data on the client-side only, to keep bad data from getting to the server at all.
C. Validation is not a security or performance concern. HTTP protects against bad data based on HTML input type and databases do not allow malicious data into the field types.
D. Validating all user input data on the client for performance reasons, and again on the server, to protect against malicious users that attempt to bypass client-side validation.
正解：D

質問 6：
Heather is preparing to move an application into production and has discovered that there is an option to create a portlet WAR file or an application WAR file. What is the conceptual difference between the two?
A. A portlet WAR file contains portlets designed to run on an IBM WebSphere Portal server or portlet container, while an application WAR file is a stand-alone web application that has no dependencies on WebSphere Portal containers, so it can be deployed to an application server.
B. An application WAR file can include profiling for personalization and configuration, while a portlet WAR file is static and cannot be configured for profiling.
C. An application WAR file is a prerequisite for deploying a portlet WAR file. It represents the container hierarchy for portlets.
D. An application WAR file can deploy multiple portlets at the same time in an application, while a portlet WAR file represents a single instance of a portlet.
正解：A
