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.

ClearPass OnConnect is a feature of the ClearPass Policy Manager that allows wired authentication on switches that do not support 802.1X or RADIUS protocols. ClearPass OnConnect uses SNMP to monitor and control the switch ports based on the device profiles and policies defined in ClearPass12. ClearPass OnConnect can provide the following benefits for the customer:

• It can enable wired authentication without requiring any changes to the existing switch infrastructure or the end-user devices. This can save the customer’s budget and time, as well as minimize the network disruption and user impact.
• It can provide visibility and control over the wired devices, such as printers, IoT devices, and laptops, that connect to the network. ClearPass OnConnect can identify the device type, user role, and location, and apply the appropriate access policies based on the customer’s security and compliance requirements. For example, ClearPass OnConnect can allow only authorized devices and users to access certain network resources, or quarantine or block any unknown or non-compliant devices.
• It can integrate with the other components of the Aruba solution, such as the MCs, MMs, APs, AirWave, and ClearPass Guest, to provide a consistent and unified network management and security solution across the wired and wireless networks. For example, ClearPass OnConnect can leverage the device profiles and policies from ClearPass Guest, or share the network health and performance data with AirWave.

Therefore, by explaining this feature, the architect can justify the proposed solution and show how it can meet the customer’s needs and expectations for wired authentication, as well as wireless authentication.
