300-085 Question #271: Real Exam Question with Answer & Explanation

Question

Options

• AIt prioritizes H.323 over SIP, and zones default is IP over ISDN
• BIt prioritizes SIP over H.323, and zones default is ISDN over IP.
• CIt prioritizes SIP over H.323, zones default is IP over ISDN.
• DIt prioritizes SIP over H.323, zones specify IP or ISDN.

Explanation

Cisco TMS prioritizes SIP over H.323, and zones are individually configured to specify IP or ISDN - there is no system-wide transport default applied across all zones.

Common mistakes.

• A. Cisco TMS does not prioritize H.323 over SIP; SIP is the higher-priority protocol in TMS call routing logic.
• B. While SIP is correctly prioritized over H.323, the claim that zones default to ISDN over IP is incorrect - TMS zones have no global ISDN default and instead require explicit per-zone transport configuration.
• C. This option incorrectly describes zones as defaulting to IP over ISDN; TMS zones carry no global transport default and must each be individually configured to specify IP or ISDN.

Concept tested. Cisco TMS call protocol prioritization and zone transport configuration
