Which two technologies would be suitable for use as Front Controller elements? (Choose two)

A.
JSP

B.
Servlet

C.
Filter

D.
POJO

E.
Custom Tag

Explanation:
* Servlet only. Works well when:
Output is a binary type. E.g.: an image
There is no output. E.g.: you are doing forwarding or redirection as in Search Engine example.
Format/layout of page is highly variable. E.g.: portal.
* JSP only. Works well when:
Output is mostly character data. E.g.: HTML
Format/layout mostly fixed.
* Combination (MVC architecture). Needed when:
A single request will result in multiple substantially differentlooking results. You have a large development team with different team members doing the Web
development and the business logic.
You perform complicated data processing, but have a relatively fixed layout
Incorrect:
Not D: In computing software, POJO is an acronym for Plain Old Java Object. The name is used to emphasize that a given object is an ordinary Java Object, not a
special object. The term “POJO” is mainly used to denote a Java object which does not follow any of the major Java object models, conventions, or frameworks.
The term continues the pattern of older terms for technologies that do not use fancy new features.
