Okta Developer Exam Study Guide


Congratulations, you are one step closer toward earning your Okta Certified Developer certification!

This exam study guide is designed to help you prepare for the Okta Developer exam. Passing this exam is a requirement for attaining Okta Certified Developer certification. Detailed exam topics and available preparation resources are outlined in this guide. Reading this guide in no way guarantees a passing score on the Okta Developer exam.

Using this study guide

At minimum, we highly recommend you thoroughly review each topic listed within the Exam Subject Areas section of this study guide. Make sure you understand and are familiar with each topic. Every single topic within that section relates to at least one question or one task on the exam. If you are not familiar with a topic, research it by either using one of the corresponding provided preparation resources, or search the Okta Help Center, Okta Product Documentation library, or the Okta Developer Platform. Some topics are best learned through hands-on experience with the Okta service.

Understanding the Types of Items Included on this Exam

Part I of this exam includes Discrete Option Multiple-Choice (DOMC) items. Part II contains Performance-based, hands-on use cases.

Understanding the DOMC Item Type

DOMC is a powerful measurement tool that produces reliable test scores. It does so by removing several “contaminants” that affect test outcomes but are unrelated to the knowledge and skills being tested. The DOMC item type levels the playing field, more fairly measuring candidate skills by improving:

  • Readability. Because test takers are required to read less, the exam tends to take less time and places fewer demands on the slow reader or the non-native English speaker.
  • Fairness. When savvy test takers are unsure of an answer, they look for clues by comparing options or gleaning information from other items on an exam. DOMC removes this test taking advantage and serves as a powerful method to assess a test taker’s actual knowledge.
  • Security. Instead of displaying all options at the same time, options are randomly presented one at a time. For each presented option, test takers must make a YES or NO decision to indicate whether they think the option is correct. Answer options are presented in random order, and in most instances, test takers are NOT presented with all the available options associated with a DOMC item. Item exposure is limited by presenting only a subset of the available options to any given test taker. Limiting item exposure makes it difficult for an exam to be compromised.

Scoring of a DOMC Item

Test takers can be assured that the DOMC item type is scored fairly and with precision.

  • If a test taker is presented with a correct option and responds YES, then that response is scored as “correct". A DOMC item can be programmed to require one or more correct responses in order to be complete and to be considered answered correctly. Typically, however, only one correct response is required.
  • If a test taker is presented with a correct option and responds NO, then that item is scored as “incorrect”.
  • If a test taker is presented with an incorrect option and responds YES, then that item is scored as “incorrect”.
  • If a test taker is presented with an incorrect option, and that test taker responds NO (technically, a correct response), scoring of the item is postponed and another option is presented.

Note: Even after a test taker responds correctly or incorrectly to an item, additional correct or incorrect options might be presented but the test taker’s responses to those options will not be scored at all. This is done to prevent test takers from guessing the correctness or incorrectness of a response.

The DOMC item format may require test takers to make some adjustments to their test-taking approaches. The reward of such effort is confidence that those test takers who are certified are truly competent in the areas tested on the exam and will represent excellence in the field.

To learn more about DOMC items, visit http://trydomc.com/home. In addition, the Okta Developer Standard Practice exam will help you become accustomed to the new test format. We highly recommend that test takers become familiar with the format of this item type before taking any Okta certification exams.

Understanding the Performance-based Use Cases in Part II of this Exam

Part II of this exam includes four performance-based hands-on use cases. Each use case consists of three or more tasks that exam takers are asked to complete within Okta Preview Orgs. This part of the exam allows exam takers to demonstrate their skill with the Okta service and Okta APIs in a natural way that mimics how developers use Okta on the job.

A use case begins with some general instructions that apply to all the tasks in that use case. The instructions for a use case are presented on a dedicated page labeled Instructions.

Okta Developer Exam Study Guide.

Succeeding the instructions are the individual tasks, each on its own dedicated page and labeled accordingly.

Each task must be completed in the order presented. Tasks build on each other, so it is important to complete Task 1 in order to move on to Task 2 and so forth.

Okta Developer Exam Study Guide.

Exam takers can go back to previous tasks and make changes as deemed necessary; however, it is important to note how changes made to a preceding task affect other tasks within the use case.

Scoring of a Performance-based Use Case

Use cases are graded upon the submission of Part II of the exam or immediately at the end of the 90-minute time clock allotted for Part II.

Navigating Part II of this Exam

Logging in to Your Okta Org

When you get to the landing page for Part II of the exam, you are presented with a notice that your Okta Org is being created. Once your Org is created, you are presented with the following pieces of information:
