HP HPE6-A47 Exam With Confidence Using Practice Dumps

the new 802.11ac deployment should have a capacity-based design for the best performance, but the existing deployment sounds like a coverage-based design. This is because a capacity-based design takes into account the number and type of clients, the applications they use, and the bandwidth they require. A coverage-based design only considers the signal strength and the absence of coverage holes. A site survey is desirable to determine the optimal locations for the new APs because it can help the architect to assess the current and future capacity needs, identify the sources of interference and noise, and optimize the channel and power settings for the new APs.

Option A is incorrect because an 802.11ac deployment does not necessarily work better with side-mounted APs. The mounting location of the APs depends on the antenna type, the ceiling height, and the RF environment.

Option C is incorrect because 802.11ac AP radios are not more sensitive to 2.4 GHz interference than 802.11n APs. In fact, 802.11ac APs operate in the 5 GHz band, which is less crowded and prone to interference than the 2.4 GHz band.

Option D is incorrect because 802.11ac APs cannot support a higher density of clients by being deployed farther apart. On the contrary, 802.11ac APs need to be deployed closer together to provide the higher data rates and throughput that 802.11ac clients expect.

Specifically, it aligns with the objectives outlined in Chapter 4: Wireless LAN Design, where the capacity-based design and site survey methods are discussed.

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.

In the event of an MM outage, MCs continue to use their existing licenses for 30 days, and the network remains up. However, you cannot change the configuration items in the controller network. In addition, the MM manages many of the higher level functions that can cause issues in the network if the MM fails. Aruba recommends a backup MM for these situations. From an economic point of view, a backup MM for a VMM is free. If a customer has a hardware MM, the customer must purchase a backup hardware MM.
