The customer needs to upgrade their wireless network, which has a single large building with four floors. The customer requires 30 APs on each floor, totaling 120 APs for the whole building. The customer also wants to use a MM-based architecture, and deployone Aruba 7030 MC on each floor, with the MCs combined in a cluster for seamless client failover and roaming. However, the proposed solution does not meet the customer’s requirements, because the Aruba 7030 MC does not support enough APs for the customer’s needs. Each Aruba 7030 MC can only support up to 64 APs, which means that deploying one on each floor would not be enough to support all the required APs. The architect should explain this limitation to the customer, and suggest a different solution that can support more APs, such as using a higher-capacity MC model, or deploying more MCs per floor.

The traditional guideline limits a wired VLAN to a /24 subnet, which provides enough IP addresses for 253 endpoints. You might have suggested one of three approaches: one VLAN per floor, one VLAN per building, or one VLAN per campus. The one VLAN per floor approach is not recommended because it interferes with roaming and adds complexity. If you did take this approach, the /24 subnets are not large enough for the requirements on every floor. You would need to ask for /23 subnets. The one VLAN per building approach would work if you considered each building its own RF domain. It provides roaming within a building and, if you are using a single cluster at the data center, between buildings. Ifyou deployed two MCs or clusters, one at each building, though, GRE tunneling would be required to support roaming between buildings.

whether the MC needs to support advanced 8.x features. This is because the Aruba 7000 Series MCs are based on the older hardware platform and can only run up to ArubaOS 6.5.x, while the Aruba 7200 Series MCs are based on the newer hardware platform and can run ArubaOS 8.x and above. ArubaOS 8.x introduces many advanced features, such as clustering, MultiZone, AirMatch, and dynamic segmentation, that are not supported by the Aruba 7000 Series MCs. Therefore, if the architect needs to design a solution that leverages these features, the Aruba 7200 Series MCs are the better choice.

Option A is incorrect because the number of wireless devices that the MC needs to support is not a key criteria to choose between the Aruba 7000 Series or 7200 Series MCs.Both series can support a similar number of devices, depending on the model and license.

Option B is incorrect because whether the MC needs to terminate VPN tunnels is not a key criteria to choose between the Aruba 7000 Series or 7200 Series MCs. Both series can terminate VPN tunnels, such as IPSec, GRE, and RAP, depending on the model and license.

Option C is incorrect because the need to deploy controllers in a cluster is not a key criteria to choose between the Aruba 7000 Series or 7200 Series MCs. Both series can participate in a cluster, as long as they run the same ArubaOS version and have the same license.
