HP HPE6-A47 Exam With Confidence Using Practice Dumps

 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).

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.

The frequency of the radio wave is one of the most important factors that determines the antenna performance and compatibility. The antenna must be designed to operate at the same frequency band as the radio, otherwise the impedance mismatch will cause signal loss and reflection. The frequency also affects the size, shape, and radiation pattern of the antenna. For example, a lower frequency requires a larger antenna to achievethe same gain and directivity as a higher frequency antenna. The frequency also determines the available bandwidth and channel spacing for the wireless communication12. Therefore, it is essential to ensure that the antenna is designed for the frequency used by the radio. References:
