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

The Fail Strategy is a configuration option for the IPS mode of inspection on Aruba gateways. It defines the action to be taken when the IPS engine crashes and cannot inspect the traffic. There are two possible options for the Fail Strategy: Bypass and Block1

If you set the Fail Strategy to Bypass, you are telling the gateway to allow the traffic to flow without inspection when the IPS engine fails. This option ensures that there is no disruption in the network connectivity, but it also exposes the network to potential threats that are not detected or prevented by the IPS engine1

If you set the Fail Strategy to Block, you are telling the gateway to stop the traffic flow until the IPS engine resumes inspection. This option ensures that there is no compromise in the network security, but it also causes a loss of network connectivity for the duration of the IPS engine failure1

This is because a parameter is a variable that can be defined and modified by the user or the script, and can be used to customize the behavior and output of the NAE script. A parameter can be referred to by using the syntax self ^ramsfname], where ramsfname is the name of the parameter.

By defining a parameter for the RADIUS server, you can make the NAE script more flexible and adaptable to different scenarios and switches. The parameter can be set to a default value, such as cp.acnsxtest.local, but it can also be changed by the user or the script based on the network conditions and requirements. For example, the user can select a different hostname or IP address for the monitored RADIUS server when they create an agent from the script, or the script can automatically detect and update the parameter based on the switch configuration. This way, the NAE script can monitor statistics from any RADIUS server defined on the switch without hard-coding the server name or IP address in the monitor URI.

A. Use this variable, %{radius-ipV when defining the monitor URI in the NAE agent script. This is not a valid recommendation because %{radius-ipV is not a valid variable in NAE scripts. Variables in NAE scripts are prefixed with self ^ramsfname], not with %. Moreover, radius-ipV is not a predefined variable that contains the RADIUS server name or IP address, but rather a generic term that could refer to any IP version.

C. Use a callback action to collect the name of any RADIUS servers defined on the switch at the time the agent is created. This is not a bad recommendation, but it is not as good as defining a parameter. A callback action is a feature that allows an NAE script to execute a command on the switch and collect its output for further processing or display. A callback action can be used to collect the name of any RADIUS servers defined on the switch by executing a command such as show radius-server or show running-config radius-server and parsing its output. However, a callback action might not be as fast or reliable as using a parameter, as it depends on the availability and responsiveness of the switch and its CLI.

D. Make the script editable so that admins can edit it on demand when they are creating scripts. This is not a good recommendation because making the script editable exposes it to potential errors or modifications that could affect its functionality or performance. Making the script editable also requires more effort and expertise from the admins, who might not be familiar with NAE scripting syntax or logic. Moreover, making the script editable does not future proof it, as it does not allow for dynamic changes or updates based on network conditions or requirements.
