When the AC is a side-mounted network, if the data is directly forwarded, then data flow () AC, if the data is tunnel forwarding mode, then data flow () AC.

Question

Options

• Ado not pass, pass
• Bdo not pass, do not pass
• Cpass through
• Dpass, not pass

Explanation

Option A is correct because in a side-mounted AC topology, direct forwarding means the AP sends data traffic straight to the upstream network without routing it through the AC - the AC only handles control signaling, so data does not pass through it. In tunnel forwarding mode, however, the AP encapsulates all data inside a CAPWAP tunnel and sends it to the AC for decapsulation and forwarding, meaning data must pass through the AC.

Option B is wrong because it incorrectly claims tunnel forwarding also bypasses the AC, ignoring that tunnel mode exists precisely to centralize data processing at the AC. Option C is wrong because it claims data passes through the AC in both modes, which contradicts the purpose of direct forwarding. Option D reverses the correct relationship, swapping the behaviors of the two modes.

Memory tip: Match the name to the path - "direct" forwarding takes the direct route (skipping the AC), while "tunnel" forwarding forces data through the AC tunnel. Direct skips, tunnel trips.
