Cisco 350-801 CLCOR

It tests implementation and operation of Cisco collaboration core technologies: call control and dial-plan behaviour, protocols and codecs, endpoint registration and management, media resources, and the underlying infrastructure those services depend on. The emphasis is on choosing and configuring the right component for a scenario rather than on troubleshooting deep faults.

The vendor page we verified does not state a question count or a time limit, so we do not publish either figure. Exam length and timing are set by Cisco and can change between revisions. Check the official exam page and your scheduling confirmation before test day and plan your pacing from that.

We do not publish a passing score because the official page we verified does not state one, and Cisco does not guarantee a fixed publicly quoted threshold. Treat any number you see elsewhere as unverified. Confirm current scoring details with Cisco directly, and aim to be comfortably consistent across every topic area rather than targeting a bare minimum.

It is genuinely demanding for candidates without hands-on collaboration experience. Candidates coming from routing and switching often underestimate call control and dial-plan logic, while voice engineers can lose marks on the infrastructure and protocol fundamentals. The reliable predictor of difficulty is hours spent configuring and observing a working cluster, not hours spent reading.

Start with infrastructure and design foundations, then move to protocols and codecs, because everything later assumes that vocabulary. Endpoints and registration come next, then call control and dial plans, and finally media resources. Studying call control before you understand codecs and registration makes dial-peer and region behaviour much harder to reason about.

Use them as diagnostics, not as a memorisation set. Answer a block without notes, then for every miss write down the underlying rule you got wrong and go verify it in vendor documentation or a lab. If you can explain why all the other options fail, the question has done its job. Volume alone without that review loop rarely moves a score.

Three recur: shallow dial-plan reasoning, where candidates recognise a pattern but cannot predict which route or translation wins; ignoring codec and region behaviour when it changes the correct answer; and skipping lab time so configuration choices feel abstract. A fourth is poor pacing from over-reading scenario stems instead of identifying the decision being tested.

Retake rules, waiting periods and costs are set by Cisco and the testing provider, and the page we verified does not state them. Confirm the current policy through your certification tracking account before scheduling a second attempt, and use the score report's topic breakdown to target the retake rather than repeating the same preparation.

No course is universally required, but structured training plus lab access is the fastest route for most people. What matters is a working environment where you can register endpoints, build and break a dial plan, and watch media behaviour change. Self-study works well if you pair documentation with deliberate lab scenarios rather than reading alone.

We verified it against Cisco's published exam page on the retrieval date shown in our sources, and we deliberately leave out figures that page did not state. Exam blueprints are revised periodically. Before booking, cross-check topic areas, logistics and any announced changes on Cisco's official site, because those details can move between revisions.
