350-801 Question #376: Real Exam Question with Answer & Explanation

Question

Refer to the exhibit. An engineer deploys this Cisco Unified Border Element configuration, but the phone at extension 2221 fails to ring. These configurations were performed already in Cisco UCM: - phone configuration and registration - SIP trunk configuration - translation pattern configuration Which action resolves the issue?

Options

• AApply voice translation-rule 3 to dial-peer 11 voip.
• BChange the destination pattern for dial-peer voice 10 to 2... $.
• CApply voice translation-rule 3 to dial-peer 10 voip.
• DReplace voice translation-rule 3 with voice translation-rule 1.

Explanation

To resolve a phone at extension 2221 failing to ring, applying 'voice translation-rule 3' to 'dial-peer voice 10' (presumably the inbound dial-peer from where calls to 2221 originate) is necessary to ensure the called number is correctly formatted for routing.

Common mistakes.

• A. Applying voice translation-rule 3 to dial-peer 11 voip might be incorrect if dial-peer 11 is not the relevant inbound dial-peer for calls to 2221 or if the rule is not intended for that specific dial-peer.
• B. Changing the destination-pattern for dial-peer voice 10 to 2...$ might be a solution, but it directly changes the matching logic of the dial-peer; if voice translation-rule 3 already exists and is designed for the issue, applying it to the correct dial-peer is more targeted.
• D. Replacing voice translation-rule 3 with voice translation-rule 1 implies an entirely different rule set, which may or may not resolve the issue and could introduce new problems if rule 3 was partially correct or intended for other scenarios.
