What happens to the data if the node at the branch site goes down?

Question

Options

• AThe data is typically rerouted over the private network.
• BData from the WebEx node is sent to SIP.
• CThe client tries to reconnect to the same collaboration bridge.
• DASR will condense the information into one outbound stream.

• A
  85% (41)
• B
  8% (4)
• C
  4% (2)
• D
  2% (1)

Explanation

Option A is correct because collaboration infrastructure (such as Cisco WebEx/CMR deployments) is designed with resilience: if a branch node fails, calls and data are automatically redirected through the private WAN/MPLS network to a central or backup node, maintaining service continuity without user intervention.

Why the distractors are wrong:

• B is wrong because SIP is a signaling protocol, not a destination for rerouted data - traffic doesn't get "sent to SIP" as a failover action.
• C is wrong because reconnecting to the same downed node would fail; the whole point of failover is to route away from the unavailable node.
• D is wrong because ASR (Automatic Speech Recognition) is a speech processing feature, not a network failover mechanism - condensing streams is unrelated to node failure recovery.

Memory tip: Think of the private network as a highway bypass - when the local exit (branch node) is closed, traffic is redirected onto the main highway (private WAN) to reach its destination another way.
