An engineer is designing a network for a customer running a wireless network with a common VLAN for all APs. The customer is experiencing unicast flooding in the Layer 2 network between the aggregation and access layers. The customer wants to reduce the flooding and improve convergence time. Which solution meets these requirements?

A. Migrate to a Layer 3 access campus design if the APs can run on separate VLANs.

B. Migrate all APs to a common Layer 2 access layer switch and run Layer 3 from the aggregation layer to all remaining access layer switches.

C. Align HSRP primary and STP root bridges and reduce ARP timers to match CAM timers on the aggregation layer switches.

D. Align HSRP primary and STP root bridges if the APs cannot run on separate VLANs.

出題：7

An engineer must design a QoS solution for a customer that is connected to an ISP over a 1Gbps link with a 100Mbps CIR. The ISP aggressively drops all traffic received over which is causing numerous TCP retransmissions. The customer is not using any RTP applications but wants to maximize bandwidth usage up to the CIR. Which QoS solution engineer choose?

A. Policer with markdown

B. Traffic shaping

C. Queuing

D. Policing
