A customer wants CPPM to authenticate non-802.1X-capable devices. An admin has created the service shown in the exhibits below:
What is one recommendation to improve security?
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 imported the root certificate for the Windows CA to the ClearPass CA Trust list.
Which usages should you add to it based on the scenario requirements?
Refer to the scenario.
A customer has an Aruba ClearPass cluster. The customer has AOS-CX switches that implement 802.1X authentication to ClearPass Policy Manager (CPPM).
Switches are using local port-access policies.
The customer wants to start tunneling wired clients that pass user authentication only to an Aruba gateway cluster. The gateway cluster should assign these clients to the “eth-internet " role. The gateway should also handle assigning clients to their VLAN, which is VLAN 20.
The plan for the enforcement policy and profiles is shown below:
The gateway cluster has two gateways with these IP addresses:
• Gateway 1
o VLAN 4085 (system IP) = 10.20.4.21
o VLAN 20 (users) = 10.20.20.1
o VLAN 4094 (WAN) = 198.51.100.14
• Gateway 2
o VLAN 4085 (system IP) = 10.20.4.22
o VLAN 20 (users) = 10.20.20.2
o VLAN 4094 (WAN) = 198.51.100.12
• VRRP on VLAN 20 = 10.20.20.254
The customer requires high availability for the tunnels between the switches and the gateway cluster. If one gateway falls, the other gateway should take over its tunnels. Also, the switch should be able to discover the gateway cluster regardless of whether one of the gateways is in the cluster.
You are setting up the UBT zone on an AOS-CX switch.
Which IP addresses should you define in the zone?
Which element helps to lay the foundation for solid network security forensics?
You are configuring gateway IDS/IPS settings in Aruba Central.
For which reason would you set the Fail Strategy to Bypass?
Refer to the scenario.

You have started to create a CA to meet the customer’s requirements for issuing certificates to mobile clients, as shown in the exhibit below.
What change will help to meet those requirements and the requirements for authenticating clients?
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?
Refer to the scenario.

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 is migrating from on-prem AD to Azure AD as its sole domain solution. The customer also manages both wired and wireless devices with Microsoft Endpoint Manager (Intune).
The customer wants to improve security for the network edge. You are helping the customer design a ClearPass deployment for this purpose. Aruba network devices will authenticate wireless and wired clients to an Aruba ClearPass Policy Manager (CPPM) cluster (which uses version 6.10).
The customer has several requirements for authentication. The clients should only pass EAP-TLS authentication if a query to Azure AD shows that they have accounts in Azure AD. To further refine the clients’ privileges, ClearPass also should use information collected by Intune to make access control decisions.
You are planning to use Azure AD as the authentication source in 802.1X services.
What should you make sure that the customer understands is required?
A customer has an AOS 10-based mobility solution, which authenticates clients to Aruba ClearPass Policy Manager (CPPM). The customer has some wireless devices that support WPA2 in personal mode only.
How can you meet these devices’ needs but improve security?
