The 642-415 exam leads to the Cisco IP Telephony Design Specialist certification from Cisco. It is positioned at the Specialist / Professional level. The exam validates the knowledge and skills expected of candidates preparing for Cisco Unified Communications Architecture and Design.

Related certifications include:

• CCDP
• CCNP Collaboration
• CCIE Collaboration

The 642-415 exam includes 35–45 questions and allows 90 minutes. 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 642-415 is 800 / 1000, and the official exam fee is $200–$300 USD. 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.

No formal prerequisites; recommended: CCDA or CCNA Collaboration, 2+ years of UC design experience
