I've taken the 2nd exam (SABE301) and it wasn't too bad. Just know which servers (services) run when you do different actions, such as:
- Knowing which servers handle scheduling CR documents
- Knowing which servers handle OLAP viewing requests.
- Knowing which servers handle scheduling WebI documents
The 3rd Exam (SABE401) was killer. In this exam, be ready for multiple correct answers (not just A or B or C, but any combination thereof). I think out of the 40 questions, there were only 5 of them with a single answer. This is a conceptual exam and less technical. There are also questions about the Auditing feature (ie, benefits of auditing, how auditing works, etc). Also, know your server limits/thresholds, and Job Server thresholds. I know there was a question regarding the Job Processing time window formula. Disaster recovery, and fault-tolerance played a big role, but sizing the environment was key. There will be many questions about the factors that one must consider when:
- sizing a server(s)
- creating a content management plan
- creating a disaster recovery plan
Hope this helps.
