A large enterprise deploys a WLAN network, and some of the SSIDs use the direct forwarding method. Which of the following descriptions about the characteristics of the direct forwarding method is…

Question

Options

• ABusiness data does not need to be migrated back to the AC, and there is no forwarding bottleneck
• BIt is convenient for centralized policy control of wireless traffic, and has obvious advantages in user
• CBetter security when data packets are forwarded
• DAC expansion is simple, just increase the number of independent ACs

• A
  81% (26)
• B
  13% (4)
• C
  6% (2)

Explanation

In direct forwarding (also called local forwarding), wireless data traffic is forwarded by the AP directly to the local network - it never travels back through the AC. This eliminates the AC as a data-plane bottleneck (A is correct), and because ACs only handle control traffic (not data), adding more ACs to expand the network is straightforward without worrying about data-forwarding capacity (D is correct).

B is wrong because centralized policy control is a feature of tunnel forwarding, not direct forwarding - when traffic bypasses the AC, it cannot be centrally inspected or policy-enforced at that point.

C is wrong because direct forwarding is actually less secure: data travels in the clear across the local network without the protection of CAPWAP tunneling back to the AC; tunnel forwarding encapsulates all traffic, offering better centralized security inspection.

Memory tip: Think of "direct" as "bypass AC" - bypassing the AC removes the bottleneck and simplifies scaling (A, D ), but it also removes centralized control and security benefits (B, C ). If a choice praises centralized management, it's describing tunnel forwarding, not direct forwarding.
