Discuss Huawei H19-401_V2.0 Exam Topic 14 Question 12

Which of the following statements are true about the wireless traffic forwarding modes on a fabric wireless network?

ATunnel forwarding facilitates centralized management and control of wireless traffic.

BDirect forwarding is more efficient.

CTunnel forwarding has the disadvantage of traffic detour, which increases the forwarding performance pressure on the WAC.

DDirect forwarding is not suitable for scenarios that have high requirements on roaming performance. This is because roaming performance deteriorates slightly when a STA roams across edges.

Suggested Answer: A, B, C, D

Huawei supports two main forwarding modes in its wireless architecture:

Tunnel Forwarding (A, C): All data traffic is encapsulated in CAPWAP and sent to the WAC. This simplifies security policy enforcement but causes 'traffic detour' and places a heavy processing load on the WAC.

Direct Forwarding (B, D): APs switch traffic locally. This is highly efficient and reduces core congestion. However, because traffic is released at the edge, maintaining session continuity (roaming) across different Layer 3 boundaries can be more complex, potentially leading to slight performance dips during inter-edge handovers compared to centralized tunneling.

A) True, centralized management is a big plus!

C) makes sense, but isn't the WAC designed to handle that pressure?

Carma 23 days ago

Wait, I thought tunnel forwarding was always better for management?

B) is spot on, direct forwarding is usually more efficient.

I disagree with D, direct forwarding can work fine in roaming scenarios.

Lachelle 1 month ago

A) is definitely true, centralized control is a big plus.

D seems a bit tricky; I remember something about roaming performance issues, but I can't recall if it's specifically due to direct forwarding.

Crista 2 months ago

I think C is correct because I recall that tunnel forwarding can create a detour for traffic, which puts more pressure on the WAC.

Raul 2 months ago

I'm not entirely sure about B, but I feel like direct forwarding is generally considered more efficient in practice.

Val 2 months ago

I remember studying that tunnel forwarding does help with centralized management, so I think A is true.
