The 642-901 exam, officially known as Cisco Building Scalable Cisco Internetworks, is the Cisco test that leads to the CCNP certification at the Professional level. Passing it validates the skills employers expect from a certified professional. It is also associated with related credentials such as Cisco Certified Network Professional (CCNP), Cisco Certified Design Professional (CCDP), Cisco Certified Internetwork Professional (CCIP).

The 642-901 exam contains 55-65 questions, and you have 75-90 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 642-901 exam is 690, and the official registration fee is USD 225-300 (historical approximate). 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.

Typically requires CCNA-level knowledge or equivalent experience
