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.

 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).

Specifically, it aligns with the objectives outlined in Chapter 6: Wireless Network Design, where the Instant and CAP modes and the MC options 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.
