The 642-978 exam is the official Cisco exam behind the Cisco Data Center Unified Computing Design Specialist certification, validating the skills measured by the Cisco Data Center Unified Computing Design Specialist Qualifier credential. It sits at the Specialist level of the Cisco certification program. It also connects to Cisco Data Center Unified Computing Design Specialist, so the knowledge you build here carries over to those tracks as well.

The 642-978 exam contains 45-55 questions to be completed within 90 minutes. Before exam day, divide the available time by the question count to work out a comfortable per-question pace, and mark any item that eats into it so you can return later instead of getting stuck. Timed sessions in the ExamPrepAway test engines make that pacing automatic — run at least two full-length mock exams under the clock so time pressure never becomes the reason you drop points.

The passing score for the 642-978 exam is Not publicly disclosed by Cisco, and the official registration fee is Approx. $200 USD. Retakes are not discounted — every new attempt means paying the full fee again — so it pays to measure yourself before you book. Work through the 62 practice questions on ExamPrepAway, sit a timed practice test, and schedule your exam only when your scores are consistently comfortable. That simple habit is the cheapest exam strategy there is.

No formal prerequisites; recommended knowledge of Cisco data center technologies and UCS design Requirements can change when Cisco revises its certification program, so confirm the current eligibility rules on the official exam page before you register.
