HPE6-A47 Exam Dumps : Designing Aruba Solutions

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 correct answer is option C, conversion of the existing Instant APs to campus APs (CAPs). This is because the existing Instant APs can be converted to CAPs by changing their operating mode and pointing them to the MC. This way, the customer can leverage the existing APs and avoid purchasing new ones. The MC can then provide centralized management, configuration, and control for the APs.

Option A is incorrect because the purchase of Universal APs is not necessary. Universal APs are APs that can operate in either Instant or CAP mode without requiring a conversion. However, the existing APs can be converted to CAPs without buying new ones.

Option B is incorrect because Aruba ClearPass is not required to onboard the APs as CAPs in the new MC-based deployment. Aruba ClearPass is a network access control (NAC) solution that provides authentication, authorization, and accounting (AAA) services for wired and wireless devices. It is not involved in the conversion of Instant APs to CAPs.

Option D is incorrect because a Virtual Mobility Controller (VMC) is not a valid option to control Instant APs. A VMC is a software-based MC that runs on a hypervisor. It can control CAPs, but not Instant APs. Instant APs can only be controlled by another Instant AP acting as a Virtual Controller (VC).

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.
