The 640-552 exam, officially known as Cisco Securing Cisco Network Devices, is the Cisco test that leads to the Cisco Certified Network Associate Security (CCNA Security) certification at the Associate level. Passing it validates the skills employers expect from a certified professional. It is also associated with related credentials such as CCNA Security.

The 640-552 exam contains 55–65 questions, and you have 90 minutes to complete them. Work out your per-question pace before test day, and flag slow items instead of stalling on them — time pressure, not knowledge, sinks many first attempts. Timed mock exams in the Actual4Exams test engines are the most reliable way to build that rhythm.

The passing score for the 640-552 exam is Variable (typically ~80% range, exam scaled score system applied), and the official registration fee is USD 250 (historical, exam retired). If you miss the mark, a retake means paying the full fee again, so book your seat only when you are ready. A practical benchmark: score consistently above the passing line on timed practice tests before scheduling the real exam.

Basic understanding of networking fundamentals (recommended CCNA-level knowledge)
