Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 377

Which dial plan design provides the most benefit to systems with many sites or overlapping site extension ranges?

Answer options

• A. LCR
• B. variable-length
• C. TEHO
• D. forced-on-net

Correct answer: B

Explanation

The variable-length dial plan design allows for greater flexibility in managing extensions, making it ideal for systems with multiple sites and overlapping extension ranges. In contrast, LCR focuses on least-cost routing, TEHO emphasizes on-net calls, and forced-on-net restricts calls to internal networks, offering less adaptability in this context.
