350-801 Question #42: Real Exam Question with Answer & Explanation

Question

Which design restriction applies to Cisco Unified Communications Manager Session Management Edition clustering over the WAN deployment with extended round-trip times in Cisco Unified CM 9.1 and later releases?

Options

• ASIP and H.323 intercluster trunks are supported.
• BOnly SIP trunk is supported.
• CSIP trunks and H.323 gateways are supported.
• DA minimum of 1.544 Mb/s bandwidth is required for all traffic between any two nodes in the
• EOnly RSVP agents can be configured and registered to the SME cluster as media resources.

Explanation

This question asks about a specific design restriction for Cisco Unified Communications Manager Session Management Edition (SME) clustering deployed over a WAN, particularly regarding supported trunk types.

Common mistakes.

• A. This is incorrect because H.323 intercluster trunks are not supported for SME clustering over a WAN.
• C. H.323 gateways are different from H.323 intercluster trunks; while H.323 gateways might be used, H.323 intercluster trunks are specifically restricted for WAN deployments of SME.
• D. While bandwidth is important, a fixed 1.544 Mb/s (T1) is not the only or most critical design restriction for SME WAN clusters, and the question is specifically about design restrictions related to trunk types.
• E. This is a specific detail about media resources and not the primary design restriction regarding trunk types for SME over WAN.
