The 642-521 exam includes 45-65 questions and allows 90-120. Before test day, divide the available time by the number of questions in a timed practice set to establish a steady per-question pace. If a difficult item starts consuming too much time, mark it for review and move forward instead of losing momentum. A full timed practice session can help you decide when to move on, when to return, and how much buffer to reserve for a final check.

The passing score for 642-521 is Cisco scaled score (varies, typically around 800/1000 equivalent), and the official exam fee is $150 USD (historical, may vary by region and time period). Because a retake requires paying the exam fee again, use timed practice results as a readiness check before scheduling your next attempt. If your performance remains inconsistent, continue reviewing weak domains and repeat a timed session before booking the exam.
