It's a great question. At the time the exam was written, it was accurate, went through technical checks, etc. In the exam guide, each of the references listed refer to the product version (3.3) on which the items were written, to provide context and guidance as well as opportunity for study. When taking the exam, the exam guide is key to knowing what to expect not only in objectives being tested, but also the content of the exam. If there is a question that is just wrong, we definitely need to know about it.
Two things can happen:
1. If a high enough amount of items are technically inaccurate, we run through a psychometric review with Subject Matter Experts and if the exam is considered inaccurate, we adjust past scores of test takers based on the new standards.
2. If a minimal number of questions are inaccurate, but the overall is still psychometrically sound, then we correct and adjust in updated versions.
We can perform this type of health check during our new version update (while we have the SMEs available.)
