I passed this exam today. My preparation was about 3 weeks seriously.I used the material SW 717,718,719. I also used sg246773 redbook. To be frank, the resources provided are not sufficient.
You should have web services knowledge and IBM SOA products like IBM busiess process server, business process modeller, business process monitor, IBM tivoli products for service deployments.SOA lifecycle. SOA integration patterns.You should also know about different standards and specification (Topic 1 of SW 719).
I got lot of questions on SOA assessment. for ex : how do you access a certain business for SOA.I think my preparation was not sufficient on this topic. I got total 71%.i would say it is an average exam not so hard and not so easy from my perspective.
Hope this helps.
Good luck!!!
