The 400-151 exam leads to the CCIE Data Center certification, a Expert-level credential from Cisco. It validates the skills measured by the Cisco CCIE Data Center Written syllabus and is a recognized step for IT professionals building their careers, and it sits alongside related credentials such as CCIE Data Center.

The Cisco CCIE Data Center Written exam includes 90-110 questions and gives you 120 minutes to complete them. That works out to a fairly tight pace, so reading each question carefully but decisively matters more than perfectionism. If a question stalls you, flag it and move on; banking the easier points first keeps time pressure from snowballing near the end. Before test day, run at least one full timed session with the Prep4SureReview practice test so the rhythm feels familiar rather than rushed.

You need Variable (Cisco does not publicly disclose passing scores) to pass the 400-151 exam, and the official registration fee is USD 450. Keep in mind that a failed attempt means paying the full fee again to retake the exam, so it pays to be honest with yourself before booking a seat. A practical benchmark: work through the 200 practice questions at Prep4SureReview until you can score comfortably above the passing line in timed mode, then schedule your exam.

No formal prerequisite. Candidates were recommended to have 3-5 years of experience with enterprise data center technologies before attempting the exam. Because Cisco may adjust its policies over time, we recommend confirming the latest requirements on the official exam page (official exam page) before you register.
