SCEA 5.0 - Carving a well qualified Java EE Architect

Sun Microsystems offers many certifications starting from programmer level to architect level. SCEA 5.0 (Sun Certified Enterprise Architect for the Java Platform, Enterprise Edition 5) certification is designed for enterprise architects responsible for building high scale enterprise applications or who wish to be prospective architects.The certification exam tests candidate's architectural knowledge in and out.
A Software Architect is the technical boss of software systems and he should act like a software doctor to resolve the issues. A basic difference between a developer and an architect is the way they design the application. Developer may not think about the scalability, maintainability, performance, etc for long run. But architect always foresees the application's future expectations about performance, scalability, etc.
What are the qualifications required to become a Java EE Architect?
I would say he/she should be a Sun Certified Java EE Architect. Because it comprises of all the necessary qualification required for a Technical Architect required for Java EE assignment. I love the way the SCEA Part 2 and Part 3 designed.
The following are the interesting topics that SCEA 5.0 Exam covers:
SCEA 5.0 Part 1
* Application Design Concepts and Principles - Tests your OO design language skills
* Common architectures - Tests the skills in evaluation of enterprise application tiers
* Integration and Messaging - Tests the architectural solution knowledge to connect Java EE with any legacy systems and architectural solution knowledge in synchronous and asynchronous message architecture
* Business Tier Technologies - Tests the design and basic API knowledge in EJB and JPA
* Web Tier Technologies - Tests the design and basic knowledge in WAF,JSP,Servlet,JSF and JSTL
* Applicability of Java EE - Tests the design decision knowledge about Java EE technologies
* Patterns - Tests the knowledge in design patterns
* Security - Tests various kinds of enterprise security including firewalls and DMZ
SCEA Part 2
A business problem will be given to you in the form of use case diagrams, business domain model, and statement format. The requirements will encompass both Functional and Non-Functional requirements. You are requested to come up with an architecture for the given business problem to meet both the functional and non-functional requirements.
It is a very challenging experience to get to know about Java EE Architecture best practices. Once you have completed your assignment, you need to upload your assignment into Sun and it will be manually evaluated by technical authors.
SCEA Part 3
This is another stimulating test to verify your architectural knowledge about design decisions. Architecture can be implemented in many ways with different design decisions. The questions will be on why you have chosen this way and why not the other way. You need to answer with brief explanation. If you have completed Part 1 and Part 2, Part 3 will be straightforward and very easy to crack.
The SCEA exam does not require any pre-certifications from Sun Microsystems. So, if you decide to take Sun Java EE Architect certification, you can very well start without any prerequisite.
How to start, where to start?
Go through the exam objectives from Sun website.

Plan for your certification process
When to take Part 1, when to take Part 2 and Part 3 is based on your preferences
Practize for your certification process
Use SCEA 5.0 Part 1 Training Lab and SCEA Part 2 & Part 3 Training Lab to get the real feel of the exam.
Take the actual exam once you get confidence from sample mock exams.
