Hi

Just want to check with you guys

Intercepting filter
MVC
Front Controller
Business Delegate
ServiceLocator
TransferObject

In HF ony the above patterns are explained. But i do see questions about other patterns like Value Objects, Data Access Objects, Fa�ade etc.

So do we need to be prepared for other than the patterns explained in HF ?

Kindly reply. Thank you

The FAQ says other patterns wont be answer for the questions found in MOCK and real exams. But i found few questions has the answer as Fa�ade, and ValueObjects. The questions are shown below. Any body can explain ?
Thank you


Why am I seeing Design Patterns in mock exams that aren't in the objectives?
Mock exams, as well as the real exam, contain answer options other than the 6 Design Patterns from the objectives. Those extra patterns are never the correct answer. Ever. Use this knowledge to your advantage.

The Value Object == Data Transfer Object == Transfer Object. I am not too sure about the other patterns I am trying to find out that answer myself. Of course it would never hurt knowing the extra patterns, but would rather work on the material that I need to know for the exam and study the other many other patterns at my leisure.

I updated the FAQ to be more specific about this. Thanks.
