The Cisco 300-420 exam, officially titled Designing Cisco Enterprise Networks, is the required test for earning the CCNP Enterprise, Cisco Certified Specialist – Enterprise Design certification, a credential at the Professional level. Passing it validates the skills Cisco expects from certified professionals, and it can also support progress toward related credentials such as Cisco Certified Network Professional (CCNP) Enterprise, Cisco Certified Specialist – Enterprise Design.

The 300-420 exam includes 55–65 questions, and you have 90 minutes to complete it. Before exam day, divide the available time by the question count so you know the pace you need to hold, and practice flagging time-consuming items for review instead of stalling on a single question. Timed sessions in the NewPassLeader test engine are the easiest way to build that rhythm before it counts.

You need Pass/Fail to pass the 300-420 exam, and the official registration fee is USD 400. Keep in mind that a failed attempt means paying that fee in full again for a retake, so avoid booking your seat on a hunch. Work through the NewPassLeader practice test until your scores sit comfortably above the passing requirement before you schedule the exam.
