The 642-426 exam is the official Cisco exam behind Cisco Troubleshooting Unified Communications (TUC) — passing it earns you the Others certification, a credential positioned at the Professional (CCVP associate exam) level. It is built for candidates who want to validate the skills measured by Cisco Troubleshooting Unified Communications (TUC). Depending on your track, the exam is also linked to the Cisco Certified Voice Professional (CCVP) certification, so one pass can move you toward more than one Cisco credential.

Recommended: CCNA and Cisco Unified Communications training (e.g., CVOICE, CIPT) Because Cisco revises its certification programs from time to time, treat this as a starting point rather than the final word. Confirm the current eligibility requirements on the official Cisco exam page before you register.
