Sun Certified Enterprise Architect for Java EE Study Guide (2nd Edition) [Repost]

Definitive, Comprehensive SCEA Exam Prep–Straight from Sun’s Exam Developers!
This book delivers complete, focused review for Sun’s new Sun Certified Enterprise Architect (SCEA) for Java EE certification exam–straight from two of the exam’s creators! SCEA lead developer/assessor Mark Cade and SCEA lead developer/assessor Humphrey Sheil offer powerful insights, real-world architectural case studies, and challenging sample questions that systematically prepare you for the actual exam. For every question, the authors show why the right answers are right–and why the other answers are wrong. Cade and Sheil cover every SCEA exam topic, skill, and technique, including:
Understanding system architecture and its goals
Decomposing larger systems into components organized by tiers or layers
Addressing requirements for scalability, maintainability, reliability, availability, extensibility, performance, and security
Building effective web (presentation) tiers, and analyzing tradeoffs associated with using web frameworks
Leveraging EJB 3’s enhancements for business tier development
Covering new enhancements in the JEE 5 platform
Choosing and architecting the best integration and messaging components for your system
Using the Java security model to enforce confidentiality, integrity, authorization, authentication, and non-repudiation
Using the most powerful and useful Java EE architecture patterns
Documenting Java EE architectures through visual models and narratives
The authors also present detailed guidance for handling every element of the SCEA exam–including your development and defense of a complete real-world architectural solution.
