You have been asked to design a high-density wireless network for a university campus. Which two principles would you apply in order to maximize the wireless network capacity? (Choose two.)

• A.Implement a four-channel design on 2.4 GHz to increase the number of available channels
• B.Choose a high minimum data rate to reduce the duty cycle.
• C.Enable 802.11n channel bonding on both 2.4 GHz and 5 GHz to increase the maximum aggregated cell throughput.
• D.increases the number of SSlDs to load-balance the client traffic.
• E.Make use of the 5-GHz band to reduce the spectrum utilization on 2.4 GHz when dual-band clients are used.

This network is running legacy STP 802.1 d. Assuming "hello_timer" is fixed to 2 seconds, which parameters can be modified to speed up convergence times after single link/node failure?

• A.The max_age and forward delay parameters can be adjusted to speed up STP convergence process.
• B.Only the transit_delay and bpdu_delay timers are configurable parameters in 802.1d to speed up STP convergence process.
• C.Only the maximum_transmission_halt_delay and diameter parameters are configurable parameters in 802. to speed up STP convergence process
• D.The transit_delay=5 and dpdu_delay=20 are recommended values, considering helto_timer=2 and specified
