Refer to the scenario.
A customer is using an AOS 10 architecture with Aruba APs and Aruba gateways (two per site). Admins have implemented auto-site clustering for gateways with the default gateway mode disabled. WLANs use tunneled mode to the gateways.
The WLAN security is WPA3-Enterprise with authentication to an Aruba ClearPass Policy Manager (CPPM) cluster VIP. RADIUS communications use RADIUS, not RadSec.
For which devices does CPPM require network device entries?
Explanation: Only visible for Actual4Cert members. You can sign-up / login (it's free).
Refer to the scenario.
# Introduction to the customer
You are helping a company add Aruba ClearPass to their network, which uses Aruba network infrastructure devices.
The company currently has a Windows domain and Windows CA. The Window CA issues certificates to domain computers, domain users, and servers such as domain controllers. An example of a certificate issued by the Windows CA is shown here.

The company is in the process of adding Microsoft Endpoint Manager (Intune) to manage its mobile clients.
The customer is maintaining the on-prem AD for now and uses Azure AD Connect to sync with Azure AD.
# Requirements for issuing certificates to mobile clients
The company wants to use ClearPass Onboard to deploy certificates automatically to mobile clients enrolled in Intune. During this process, Onboard should communicate with Azure AD to validate the clients. High availability should also be provided for this scenario; in other words, clients should be able to get certificates from Subscriber 2 if Subscriber 1 is down.
The Intune admins intend to create certificate profiles that include a UPN SAN with the UPN of the user who enrolled the device.
# Requirements for authenticating clients
The customer requires all types of clients to connect and authenticate on the same corporate SSID.
The company wants CPPM to use these authentication methods:
* EAP-TLS to authenticate users on mobile clients registered in Intune
* TEAR, with EAP-TLS as the inner method to authenticate Windows domain computers and the users on them To succeed, EAP-TLS (standalone or as a TEAP method) clients must meet these requirements:
Their certificate is valid and is not revoked, as validated by OCSP
The client's username matches an account in AD
# Requirements for assigning clients to roles
After authentication, the customer wants the CPPM to assign clients to ClearPass roles based on the following rules:
* Clients with certificates issued by Onboard are assigned the "mobile-onboarded" role
* Clients that have passed TEAP Method 1 are assigned the "domain-computer" role Clients in the AD group "Medical" are assigned the "medical-staff" role Clients in the AD group "Reception" are assigned to the "reception-staff" role The customer requires CPPM to assign authenticated clients to AOS firewall roles as follows:
* Assign medical staff on mobile-onboarded clients to the "medical-mobile" firewall role
* Assign other mobile-onboarded clients to the "mobile-other" firewall role
* Assign medical staff on domain computers to the "medical-domain" firewall role
* All reception staff on domain computers to the "reception-domain" firewall role
* All domain computers with no valid user logged in to the "computer-only" firewall role
* Deny other clients' access
# Other requirements
Communications between ClearPass servers and on-prem AD domain controllers must be encrypted.
# Network topology
For the network infrastructure, this customer has Aruba APs and Aruba gateways, which are managed by Central. APs use tunneled WLANs, which tunnel traffic to the gateway cluster. The customer also has AOS-CX switches that are not managed by Central at this point.
# ClearPass cluster IP addressing and hostnames
A customer's ClearPass cluster has these IP addresses:
* Publisher = 10.47.47.5
* Subscriber 1 = 10.47.47.6
* Subscriber 2 = 10.47.47.7
* Virtual IP with Subscriber 1 and Subscriber 2 = 10.47.47.8
The customer's DNS server has these entries
* cp.acnsxtest.com = 10.47.47.5
* cps1.acnsxtest.com = 10.47.47.6
* cps2.acnsxtest.com = 10.47.47.7
* radius.acnsxtest.com = 10.47.47.8
* onboard.acnsxtest.com = 10.47.47.8
You have created a role mapping policy as shown in the exhibits below.
What is one change that you need to make to this policy?
Refer to the scenario.
A customer requires these rights for clients in the "medical-mobile" AOS firewall role on Aruba Mobility Controllers (MCs):
* Permitted to receive IP addresses with DHCP
* Permitted access to DNS services from 10.8.9.7 and no other server
* Permitted access to all subnets in the 10.1.0.0/16 range except denied access to 10.1.12.0/22 Denied access to other 10.0.0.0/8 subnets
* Permitted access to the Internet
Denied access to the WLAN for a period of time if they send any SSH traffic Denied access to the WLAN for a period of time if they send any Telnet traffic Denied access to all high-risk websites External devices should not be permitted to initiate sessions with "medical-mobile" clients, only send return traffic.
The exhibits below show the configuration for the role.
What setting not shown in the exhibit must you check to ensure that the requirements of the scenario are met?

A customer wants CPPM to authenticate non-802.1X-capable devices. An admin has created the service shown in the exhibits below:

Refer to the scenario.
A customer requires these rights for clients in the "medical-mobile" AOS firewall role on Aruba Mobility Controllers (MCs):
Permitted to r* eceive IP addresses with DHCP
* Permitted access to DNS services from 10.8.9.7 and no other server
* Permitted access to all subnets in the 10.1.0.0/16 range except denied access to 10.1.12.0/22

* Denied access to all high-risk websites
External devices should not be permitted to initiate sessions with "medical-mobile" clients, only send return traffic.
The exhibits below show the configuration for the role.
There are multiple issues with this configuration. What is one change you must make to meet the scenario requirements? (In the options, rules in a policy are referenced from top to bottom. For example,
"medical-mobile" rule 1 is "ipv4 any any svc-dhcp permit," and rule 8 is "ipv4 any any any permit".)
