300-070 Question #276: Real Exam Question with Answer & Explanation

The correct answer is C: flow-around. In CUBE (Cisco Unified Border Element), 'flow-around' mode allows RTP media to travel directly between the two endpoints, bypassing the CUBE device entirely. Because CUBE is not in the media path, it cannot hide or mask the real IP addresses of either endpoint from the other - pr

Question

When using video in the Cisco Unified Border Element, which RTP flow offers no protection from the address hiding perspective?

Options

AEarly offer
BDelayed offer
Cflow-around
Dflow-through

Explanation

In CUBE (Cisco Unified Border Element), 'flow-around' mode allows RTP media to travel directly between the two endpoints, bypassing the CUBE device entirely. Because CUBE is not in the media path, it cannot hide or mask the real IP addresses of either endpoint from the other - providing zero address-hiding protection. 'Flow-through' mode forces all RTP packets to traverse CUBE, which rewrites source/destination IP addressing and thereby conceals internal endpoint addresses. Early offer and delayed offer refer to SDP negotiation timing, not RTP flow protection.
