Common Questions About the Cisco 642-998 Exam
What is the Cisco Designing Cisco Data Center Unified Computing exam all about?
The 642-998 exam is the official Cisco exam behind the CCNP Data Center certification, validating the skills measured by the Cisco Designing Cisco Data Center Unified Computing credential. It sits at the Professional level of the Cisco certification program. It also connects to CCNP Data Center, Cisco Data Center Unified Computing Design Specialist, so the knowledge you build here carries over to those tracks as well.
How many questions are on the 642-998 exam, and how much time do I get?
The 642-998 exam contains 65-75 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 Getcertkey 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.
Are there any prerequisites for the 642-998 exam?
No mandatory prerequisite for the exam itself. It was commonly used as a design specialization exam within the CCNP Data Center certification track, where candidates completed the required core and specialization exams. Requirements can change when Cisco revises its certification program, so confirm the current eligibility rules on the official exam page before you register.
