This is because a downloadable user role (DUR) is a feature that allows the switch to use a central ClearPass server to download user-roles to the switch for authenticated users12 A DUR can contain various attributes and rules that define the access level and privileges of the user, such as VLAN, ACL, PoE, reauthentication period, etc3 A DUR can also be customized and updated on the ClearPass server without requiring any changes on the switch1

A DUR can be used to create a “provision” role that allows users to enroll new wired clients in Intune. The “provision” role can have limited access that only lets them enroll and receive certificates from the Intune service. The “provision” role can also have rules that restrict the Internet access of the users to only the necessary sites, such as the Intune portal and the certificate authority. The rules can be based on IPv4 or IPv6 addresses, depending on the network configuration and preference2

A. Configuring the rules for the “provision” role with IPv6 addresses, which tend to be more stable. This is not a valid recommendation because it does not address how to create and apply the “provision” role on the switch. Moreover, IPv6 addresses do not necessarily tend to be more stable than IPv4 addresses, as both protocols have their own advantages and disadvantages4

B. Enabling tunneling to the MCs on the “provision” role and then setting up the privileges on the MCs. This is not a valid recommendation because it does not explain how to enable tunneling or what MCs are. Moreover, tunneling is a technique that encapsulates one network protocol within another, which adds complexity and overhead to the network communication5

D. Assigning the “provision” role to a VLAN and then setting up the rules within a Layer 2 access control list (ACL). This is not a valid recommendation because it does not explain how to assign a role to a VLAN or how to create a Layer 2 ACL on the switch. Moreover, a Layer 2 ACL is limited in its filtering capabilities, as it can only match on MAC addresses or Ethernet types, which might not be sufficient for restricting Internet access to specific sites

To configure user-based tunneling (UBT) on an AOS-CX switch, you need to specify the IP addresses of the mobility gateways that will receive the tunneled traffic from the switch 1. The primary controller is the preferred gateway for the switch to establish a tunnel, and the backup controller is the alternative gateway in case the primary controller fails or becomes unreachable 1. The IP addresses of the gateways should be their system IP addresses, which are used for inter-controller communication and cluster discovery 2.

In this scenario, the customer has a gateway cluster with two gateways, each with a system IP address on VLAN 4085. Therefore, the switch should use these system IP addresses as the primary and backup controllers for UBT. The IP addresses of the gateways on VLAN 20 and VLAN 4094 are not relevant for UBT, as they are used for user traffic and WAN connectivity, respectively 2. The VRRP IP address on VLAN 20 is also not applicable for UBT, as it is a virtual IP address that is not associated with any specific gateway 3.

Therefore, the best option is to use 10.20.4.21 as the primary controller and 10.20.4.22 as the backup controller for UBT on the switch. This will ensure high availability and cluster discovery for the tunneled traffic from the switch to the gateway cluster 12.

Aruba Central supports site-to-site VPNs between AOS 10 gateways, which are Aruba devices that provide routing, firewall, and VPN functions. Aruba Central can automatically provision and manage the site-to-site VPNs using the VPN Manager feature. The VPN Manager allows you to create VPN groups that consist of one or more hubs and branches, and define the VPN settings for each group1

Aruba Central uses IPsec as the protocol to secure the site-to-site connections between the AOS 10 gateways. IPsec is a standard protocol that provides encryption, authentication, and integrity for IP packets. Aruba Central automatically establishes IPsec tunnels for all site-to-site connections using keys that are securely distributed by Central. The keys are generated by Central and pushed to the gateways using a secure channel. The keys are rotated periodically to enhance security2
