The 642-415 exam is the official Cisco exam behind the IP Communications certification, validating the skills measured by the Cisco Unified Communications Architecture and Design credential. It sits at the Specialist level of the Cisco certification program. It also connects to Cisco IP Telephony Design Specialist, so the knowledge you build here carries over to those tracks as well.

Recommended: Cisco Unified Communications training and experience in IP Telephony & network design; no mandatory prerequisite exam. Requirements can change when Cisco revises its certification program, so confirm the current eligibility rules on the official exam page before you register.
