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.

Specifically, it aligns with the objectives outlined in Chapter 6: Wireless Network Design, where the MC selection and ArubaOS 8.x features are discussed.

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.

 A metal firewall is a significant RF obstacle that can be difficult to see visually and might require access to blueprints. A metal firewall is a type of fire-resistant barrier that is made of metal or metal-clad materials and is used to separate different sections of a building or a network. A metal firewall can block or attenuate RF signals that pass through it, causing coverage gaps, signal degradation, or interference in the wireless deployment. A metal firewall can also reflect RF signals, creating multipath fading or distortion in the wireless environment. Therefore, an architect needs to identify the location and thickness of any metal firewalls in the building and account for their impact on the RF design. A metal firewall may require additional access points, antennas, or cabling to provide adequate coverage and performance across the wireless deployment. A metal firewall may also affect the channel planning, transmit power settings, and antenna orientation of the access points and radios. A metal firewall can be difficult to see visually, as it may be hidden behind walls, ceilings, or floors, or blended with other materials.Therefore, an architect might need access to blueprints or other sources of information to locate and measure any metal firewalls in the building. References:
