Benefits to the IT Employer
The Oracle Certification Program is valuable to hiring managers who want to distinguish among candidates for critical IT positions.
For companies that send employees through annual IT training, certification ensures a return on the training investment by validating the knowledge and understanding gained in training sessions. Companies can also combine certification with an employee development program to enhance employee loyalty and performance on the job.
Hiring certified professionals has a direct impact on a company's bottom line, as these conclusions from a research study by International Data Corporation** suggest:

• Certified professionals handled 40% more support calls per person, per day, than uncertified staff.
• Companies that advocated certification reported 49% less downtime than those that did not.
• For the majority of companies surveyed, the savings from increased effectiveness paid the costs of certification in fewer than nine months.

My Opinions

The exam assumes architecture level experience within the SOA space.

For example, what role does BAM (Business Activity Monitoring) play in your enterprise? What is the best way to push data to BAM? How does this, if at all, impact your main operational process? Unless you have architected the usage of and/or implemented BAM, you may not know. If you can answer these questions, then you should be able to answer one of the BAM related questions in the exam.

Being a perfectionist, I noticed a few grammatical errors in the exam, missing periods, double quotes not closed, etc., but nothing that would impact your understanding of the question.

Final thoughts:

• Follow what I mentioned in "Preparing for the Exam". This will give you what you need to cover 75% of the exam.
• Questions are not technical in nature. For example, you will not find questions that ask "What is the request security token structure in WS-Trust?" You will most likely encounter questions such as "Company X currently has services on a legacy system and want to migrate them off. What should they do?"
• Go through the mock exams.
• Know the BEA White Paper Domain Model For SOA by heart. If you would like the summary and study notes I made from this white paper, then contact me and I'll be happy to share it.
• The ORACLE mock exams I listed above have a few questions that are similar to those that appear in the exam, so going through them will probably firm up your concepts.
