Which Cisco Unified Border Element configuration is correct when deployed with Cisco UCCE Unified CVP?

Question

Options

• BYou must configure Cisco Unified Border Element as media pass flow-around mode.
• CYou must configure Cisco Unified Border Element as media pass flow-through mode.

Explanation

When Cisco Unified Border Element (CUBE) is deployed with UCCE and Unified CVP, flow-through mode is mandatory because CVP must remain in the media path to deliver its core services - VXML-based IVR prompting, DTMF collection, call recording, and agent whisper announcements. In flow-through mode, RTP media actually traverses CUBE, allowing CVP's media server to insert audio into the call stream.

Why the others are wrong:

• A is wrong because CUBE can handle both VXML browser sessions and standard call routing - no dedicated gateway is architecturally required just for VXML.
• B (flow-around) is the classic wrong answer - flow-around lets media bypass CUBE entirely (signaling only), which breaks CVP's ability to serve prompts and control media, making it incompatible with CVP deployments.
• D is wrong because box-to-box redundancy is an optional high-availability design choice, not a deployment requirement for UCCE/CVP integration.

Memory tip: Think "CVP needs to be in the FLOW" - CVP is a media-aware platform, so media must flow through CUBE (not around it) to keep CVP in the path. If you see "flow-around" in an exam option involving CVP, eliminate it immediately.
