Cisco Implementing Cisco IOS Unified Communications Advanced is an official exam run by Cisco under exam code 642-145. Passing it awards the Cisco IOS Unified Communications Advanced certification, which sits at the Professional tier. It also counts toward related credentials such as Cisco Certified Network Professional (CCNP Voice / Collaboration - legacy). Certified professionals remain in shorter supply than the market wants, which is precisely why this exam keeps showing up in conversations about better roles and better pay.

The Cisco Implementing Cisco IOS Unified Communications Advanced exam gives you 90 minutes to work through Approximately 55–65 questions. That is a tight ratio, and it punishes candidates who get emotionally attached to any single item. The fix is mechanical: answer what you know, flag what you do not, and keep moving. A few full-length timed runs in the Prep4SureReview test engine, with its randomized question order, will calibrate your pace far better than untimed reading ever could.

The official fee for Cisco Implementing Cisco IOS Unified Communications Advanced is USD 150–300 (varies by region and time; legacy exam pricing), and Cisco does not publicly publish a fixed passing score (scoring varies) is what passing takes. The uncomfortable part: retakes cost the full USD 150–300 (varies by region and time; legacy exam pricing) again, which makes preparation the cheapest line item in this whole project. Before booking, put yourself through repeated scored sessions with the Prep4SureReview practice tests and compare results over time; a stable margin above the passing line, not a single lucky run, is when you are ready.

Recommended prior knowledge of Cisco voice networking and CCNP-level routing and switching concepts.
