Oracle APEX Exam at a Glance

What the Oracle APEX is and how it works

According to Oracle University, “Format Multiple Choice Duration 90 Minutes Number of Questions 50 Passing Score 68%”^[1]

The Oracle APEX Cloud Developer Professional exam checks whether you can build and maintain applications with Oracle Application Express. It covers the tools developers use every day, such as Page Designer, forms, reports, dynamic actions, shared components and security settings.

Delivery. Oracle University delivers the exam as a proctored online test. Its exam page says you can "test anytime, anywhere in a highly secure environment." Before you book, check what Oracle asks of your computer, room and ID.

Format and timing. You get 50 multiple-choice questions and 90 minutes to answer them. Some questions describe a short scenario and ask which APEX feature or setting fits it best.

Scoring. The passing score is 68%. Your results appear on screen when the exam ends, so you do not have to wait for a later report.

What we could not verify. We have not confirmed the price, eligibility rules, retake waiting periods, how long the credential stays valid, or the official list of exam topics. These details can change and may differ by region. Check the exam page on Oracle MyLearn before you register, and treat Oracle University as the final word on any rule.

Worked examples: how to reason through Oracle APEX questions

These are practice questions written for this site, not questions from the real exam. Each explanation shows why the right answer is right and why the others are wrong.

Example 1

Question: What happens in Oracle APEX when a navigation menu List Entry has no Target URL defined?

1. It acts as a parent-only label that expands to show child entries when clicked
2. It throws a runtime error
3. It redirects to the home page
4. It is hidden from all users

Answer: A. It acts as a parent-only label that expands to show child entries when clicked

Explanation:

Correct: A. In a navigation menu list, an entry with no Target URL has nowhere to send the user. APEX shows it as a parent label, and clicking it opens or closes the child entries beneath it. This lets you group related pages under one heading without building a page just for that heading.

B is wrong because a missing target is a normal setting, not an error. C is wrong because APEX does not fall back to the home page. You would need to set that target yourself. D is wrong because whether an entry is shown depends on its conditions and authorization scheme, not on its target.

Rule to remember: the target decides what a list entry does when clicked. Conditions and authorization decide who sees it.

Example 2

Question: Which processing point is enabled for computations during page processing?

1. Processing
2. After Submit
3. After Processing
4. Validating

Answer: A. Processing

Explanation:

Keyed answer: A, Processing. When a page is submitted, APEX runs its server-side work at set points in order: After Submit, then Validating, then Processing, then After Processing. This question keys Processing as the point where computations run during page processing, alongside the page's processes.

B, After Submit, is also a place where developers often put computations, so read the wording closely. This question asks about page processing itself. C, After Processing, runs after the main processes have finished, which is too late for values those processes need. D, Validating, is the stage where validations check submitted values. It is not where values get computed.

Rule to remember: learn the order of the processing points in Page Designer's Processing tab, and match each computation to the point where its result is first needed. Check Oracle's documentation for how your APEX version labels these points.

Example 3

Question: John has a form page with an email item and a status item. What must John do to ensure that the email item is populated before users can enter any value into the status item on the form page?

1. Dynamic action on the email item
2. Validation on the email item
3. Plug-in for the status item
4. Server-side condition on the status item

Answer: B. Validation on the email item

Explanation:

Keyed answer: B, Validation on the email item. A validation is a server-side check that runs when the page is submitted. A "not null" validation on the email item rejects any submission without an email and shows an error. This makes sure the status value is never saved without an email next to it.

A is wrong because a dynamic action changes behaviour in the browser, such as hiding or disabling a field. That improves the user experience, but users can get around it, so it does not enforce a rule. C is wrong because a plug-in adds a custom component, which is far more than this task needs. D is wrong because a server-side condition controls whether the status item is rendered at all. It does not check what the user enters.

Rule to remember: use validations to enforce data rules and dynamic actions to shape the experience in the browser.

How to use these practice tests

Start with the official page. Read the exam page on Oracle MyLearn and note the format: 50 questions, 90 minutes, a 68% pass mark. Also note any topic list or recommended training Oracle links to.

Take a baseline. Do the full practice test without notes. Write down which topics cost you the most marks.

Work topic by topic. Start with your weakest areas. Most APEX work centres on the Page Designer, Form Development, Report Building and Dynamic Actions sets, so begin there. Then move on to Shared Components, Authentication and Security and RESTful Services.

Build what you miss. When you get a question wrong, build that feature in a free APEX workspace. Seeing where a setting lives in Page Designer helps it stick better than rereading.

Rehearse under time pressure. In the last week, take the full test again with a 90-minute timer. Review every answer you got wrong or guessed, and check the official documentation on any point where our explanation and Oracle's wording disagree.
