350-801 Question #391: Real Exam Question with Answer & Explanation

Question

The enterprise network is migrating to a global dial plan and running a few devices in the test phase. Which change is performed by the system to the information dialed when the Cisco UCM endpoint dials an external destination under a global dial plan?

Options

• AThe calling party is globalized using translation patterns
• BThe normalization script modifies the calling party
• CThe destination is transformed using site-specific route patterns
• DThe destination is globalized using translation patterns to normalize the called party

Explanation

In a Cisco UCM global dial plan, the system globalizes the dialed destination by utilizing translation patterns to normalize the called party's number.

Common mistakes.

• A. The question specifically asks about the dialed destination, not the calling party, making this answer incorrect in context.
• B. While normalization scripts can be used, translation patterns are the primary mechanism for globalizing and normalizing the called party number within the context of a Cisco UCM global dial plan.
• C. The destination is globalized and normalized for consistent routing across the global plan, not merely transformed using site-specific route patterns, which would defeat the purpose of globalization.
