What are three drawbacks of this implementation? (Choose three.)
A. Portability to all browsers with minimal re-work for cross browser compatibility.
B. Readily available development tool kits to support automated testing, debugging, re-factoring.
C. Reduction of page refreshes to enhance user experience.
D. Simulating client state on the browser and reducing the number of views.
I selected B,C,D.
The correct answers are-
Options A, B, E are correct.
Option D is incorrect because simulating the client state is a way to address the thick client.
I get it C, D are wrong answers.
But how can you say that A,E are drawbacks of this implementation. In reality they look as advantages. Can any expert clear my confusion on this?
