After not being capable of take it anymore than 4 months of frustration and confusion between pile of diffrent version of specifications and their jargons, I finally ended up on exam seat to face THE 310-230 and believe me it was horrible experience than my 3rd semester maths exam paper in college.
Most of questions (almost 40) were multiple choice. Some options were very close in wording that rip my brain apart. Exam had 65 questions. I had 43 right. Surprisingly, I was short of time at last.(was on question #43 and had 22 min left). because most of questions were based on practical situation and restrctions. So you have to read carefully. Exam interface didn't show what question I was on and how many left. I think this GPS facility should be added now.
Well, here is my(valuable) experience.
It started well with XML schema,WSDL,SOAP structures and WS-I. I was hoping to see more questions on JAXR,JAXP,SAAJ,UDDI. However, things went south when Security and WSIT comes into the picture. I was badly hurt in these two sections. I see 1 question on SAAJ,2 on UDDI, 4-5 on JAXR,2 questions on schema,4 questions on wsdl, 1 question on StAX, 7-8 questions on JAX-WS and design(SOA) each, 4-5 question on REST and JSON each, 3-4 question on Java EE(pkg,benefits of JEE container) Rest all credit goes to Security and WSIT.
I read Ivan and Mikalai study guide(Thank you very much guys. You save me.), two books on webservice basics, specification of SAAJ,JAXR,SOAP,WSDL,BP-1.0 and 1.1. I did all practical examples from Ivan's guide. My advice is read more articles on Security(ws-securitypolicy,ws-security,ws-trust,SAML,XKMS, XACML, encryption,digital signature) and WSIT(developement and challenges in C# and .NET, WCF client). I'm Java developer and that cost me in WSIT section. Also be pro on API methods.
What I read was not enough and that gave me brain stroke and trauma. Wish you all best of luck and take the exam seriously.
Based on your experience, what would be the most important exam topics that I should give more attention so I can pass with a regular note ? I mean is that I'd like to study only enough to be approved....
I'm asking because the contents of the certification is big and there is the possibility to drop a few questions of some topics on which I believe does not worth study....
