ANSWER: Please visit the SAP Certification website for details about SAP Education's certification programs, benefits and offerings.

Education orange_arrow.gif QUESTION: How do I prepare for this exams?

ANSWER: It is recommended you work with Adaptive Server Enterprise 15.0* for at least 6 months before taking the exam. If you have taken a corresponding course, it is suggested you review all of the content, especially topics that you have yet to master.

*This exam is based on the Adaptive Server Enterprise 15.0 GA version. Any functionality that is new or changed in later releases are not included in this exam.

We also recommend preparing by:

Spending a minimum of 40 hours thoroughly covering all topics listed in the exam study guide

Taking the following recommended courses:

  • Powering Up with ASE 15.0 (EDB366)
  • Fast Track to Adaptive Server Enterprise (EDB116)
  • Performance and Tuning: Adaptive Server Enterprise Query Optimizer (EDB634)
  • Mastering Transact-SQL Programming: Advanced Tips & Techniques (EDB559)
  • Logical Database Design (SYB144)
  • Physical Database Design (EDB110)

Education orange_arrow.gif QUESTION: What is the format of this exam?

ANSWER: Each candidate will have one hour and thirty minutes to complete the exam which consists of 60 multiple-choice questions. The passing grade is 70% (42 questions answered correctly).

Education orange_arrow.gif QUESTION: What are some suggestions for when I take this exam?

ANSWER: Space your time accordingly and do not spend too much time on each question. When answering a question, you'll have the opportunity to mark an answer "for review". Keep this in mind, as it will allow you to revisit your marked questions later, before finally submitting your exam.
