FAQ
303 Exam FAQ
Common questions about the exam itself
What background do I need before attempting exam 303?
You must hold an active F5 Certified BIG-IP Administrator (F5-CA) credential before scheduling exam 303. This prerequisite ensures you have foundational knowledge of BIG-IP systems. Exam 303 cannot be scheduled until F5-CA shows active in your CertView profile.
How long is the 303 exam and how many questions does it contain?
Exam 303 is 90 minutes long with 80 total questions, of which 70 are scored and 10 are pilot items that do not affect your score. This works out to roughly 68 seconds per question, making the pace brisk.
What score do I need to pass exam 303?
The passing score is 245 out of a range between 100 and 350, which is approximately 70 percent of the scoring range. Scores are scaled rather than a direct count of correct answers, accounting for question difficulty.
Which domain in exam 303 is hardest for candidates?
Architecture/Design and Policy Creation is often challenging because it requires understanding how to create policies that protect against real attacks while preserving application functionality. The exam rewards knowing how to apply surgical rules rather than defaulting to broad blocking.
How long does preparation for exam 303 realistically take?
This depends on your hands-on experience with BIG-IP ASM. Candidates with solid experience managing security policies need less time than those new to ASM. The exam tests recognition and real-world decision-making rather than memorized facts, so practical lab work matters more than study hours.
What happens on exam day for 303?
You sit a proctored exam at a Pearson VUE testing center or online. You must bring two forms of valid, signed ID to an in-person session, with one being government-issued and including a photo. The exam is delivered as a computer-based test with multiple-choice and scenario-based questions.
What are the retake rules for exam 303?
After failing, you must wait 15 days before your first retake and 30 days after a second failure. You can schedule a retake during the wait period but cannot sit the exam until the waiting period ends. Each retake costs the same USD 180 fee.
How long does the BIG-IP ASM Specialist certification stay valid?
The F5 Certified Technology Specialist, BIG-IP ASM certification is valid for 2 years from the date you pass exam 303. After 2 years, you must recertify by passing the exam again or by completing other renewal requirements F5 may offer.
What job role does exam 303 map to?
Exam 303 targets four roles across the ASM lifecycle: security architects designing policies, security analysts maintaining them, security operations specialists interpreting attack logs, and system administrators troubleshooting ASM performance.
How does exam 303 relate to other F5 certifications?
Passing exam 303 earns you F5 Certified Technology Specialist, BIG-IP ASM, which is a prerequisite for the Security Solutions Expert certification track. It builds on the F5 Certified BIG-IP Administrator credential and is one step toward advanced F5 security certifications.
