The 642-980 exam is the official Cisco exam behind Cisco Troubleshooting Cisco Data Center Unified Fabric (DCUFT) — passing it earns you the Cisco Data Center Unified Fabric Troubleshooting certification, a credential positioned at the Professional level. It is built for candidates who want to validate the skills measured by Cisco Troubleshooting Cisco Data Center Unified Fabric (DCUFT). Depending on your track, the exam is also linked to the CCNP Data Center and Cisco Data Center specialization certifications certifications, so one pass can move you toward more than one Cisco credential.
The 642-980 exam presents 55-65 questions to be completed within 90-120. That pace leaves little room for second-guessing: read each question carefully on the first pass, flag the ones you want to revisit, and keep moving instead of stalling on a single item. Before exam day, run at least one full timed session in the TestSimulate desktop or online test engine with a comparable question load — a steady rhythm under the clock is a trainable skill, and it is often what separates a pass from a near miss.
