You are designing a wireless guest anchoring solution for a large company.
Forty-five Cisco WLCs running 7.0.116.0 code are deployed in the corporate network.
You expect about 3000 devices to use the guest network at any one time.
A junior wireless administrator has suggested using a single 4402-12 WLC running 7.0.116.0 as the anchor controller.

A. B. C. D.C.
The question is asking about designing a wireless guest anchoring solution for a large company. The company has 45 Cisco WLCs running 7.0.116.0 code deployed in the corporate network. The guest network is expected to have about 3000 devices using it at any one time. A junior wireless administrator has suggested using a single 4402-12 WLC running 7.0.116.0 as the anchor controller, and we need to determine if this is a feasible solution.
Option A states that using a 4402-12 WLC is the best option based on the design requirements because it is currently the least expensive WLC that supports auto-anchoring. However, this option does not take into account the number of devices that will be using the guest network. Therefore, it cannot be the correct answer.
Option B states that using a 4402 WLC is not feasible because 4402 WLCs do not support the 7.0 release of code. However, the question specifically states that the company has 45 Cisco WLCs running 7.0.116.0 code, so this option is not correct.
Option C states that a single 4402 WLC supports only 2500 client database entries and therefore does not meet the design requirements. This is a valid concern because the guest network is expected to have about 3000 devices using it at any one time. Therefore, a single 4402-12 WLC would not be able to support all of the devices and cannot be the correct answer.
Option D states that a single 4402-12 WLC, regardless of code, supports only 40 simultaneous EoIP tunnels and therefore does not meet the design requirements. This option is not relevant to the question because the question is asking about designing a wireless guest anchoring solution, not about EoIP tunnels.
In conclusion, the correct answer is option C because a single 4402-12 WLC only supports 2500 client database entries, which is less than the expected number of devices that will be using the guest network at any one time. Therefore, a different solution needs to be considered to meet the design requirements.
