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.The customer wants you to configure CPPM to collect information from Intune on demand during the authentication process.What should you tell the Intune admins about the certificates issued to clients?They must be issued by a well-known, trusted C

• They must include the Intune ID in the subject name.
• They must include the client MAC address in the subject name.
• They must be issued by a ClearPass Onboard CA.

A customer has an AOS 10-based solution, including Aruba APs. The customer wants to use Cloud Auth to authenticate non-802.1X capable IoT devices.What is a prerequisite for setting up the device role mappings?

• Configuring a NetConductor-based fabric
• Configuring Device Insight (client profile) tags in Central
• Integrating Aruba ClearPass Policy Manager (CPPM) and Device Insight
• Creating global role-to-role firewall policies in Central

You are configuring gateway IDS/IPS settings in Aruba Central. For which reason would you set the Fail Strategy to Bypass?

• To permit traffic if the IPS engine falls to inspect It
• To enable the gateway to honor the allowlist settings configured in IDS/IPS policies
• To tell gateways to stop enforcing IDS/IPS policies if they lose connectivity to the Internet
• To avoid wasting IPS engine resources on filtering traffic for unauthenticated clients

Refer to the scenario.A customer has an AOS10 architecture that is managed by Aruba Central. Aruba infrastructure devices authenticate clients to an Aruba ClearPass cluster.In Aruba Central, you are examining network traffic flows on a wireless IoT device that is categorized as “Raspberry Pi” clients. You see SSH traffic. You then check several more wireless IoT clients and see that they are sending SSH also.You want a fast way to find a list of all the IoT clients that have used SSH. What step can you take?

• Create and apply a Central client profile tag that selects the SSH application and the clients' category.
• Run a search for SSH traffic and loT client IDs in Aruba ClearPass Policy Manager's (CPPM's) accounting information.
• Use Central's Live Events monitoring tool to detect which clients meet the desired criteria.
• Use Central's Gateway IDS/IPS Security Dashboard to search for SSH events and sources.

To further refine the clients’ privileges, ClearPass also should use information collected by Intune to make access control decisions.Assume that the Azure AD deployment has the proper prerequisites established.You are planning the CPPM authentication source that you will reference as the authentication source in 802.1X services.How should you set up this authentication source?

• As Kerberos type
• As Active Directory type
• As HTTP type, referencing the Intune extension
• AS HTTP type, referencing Azure AD's FODN

What should you make sure that the customer understands is required?

• An app registration on Azure AD that references the CPPM's FQDN
• Windows 365 subscriptions
• CPPM's RADIUS certificate was imported as trusted in the Azure AD directory
• Azure AD Domain Services

A customer requires a secure solution for connecting remote users to the corporate main site. You are designing a client-to-site virtual private network (VPN) based on Aruba VIA and Aruba Mobility Controllers acting as VPN Concentrators (VPNCs). Remote users will first use the VIA client to contact the VPNCs and obtain connection settings.The users should only be allowed to receive the settings if they are the customer's “RemoteEmployees” AD group. After receiving the settings, the VIA clients will automatically establish VPN connections, authenticating to CPPM with certificates.What should you do to help ensure that only authorized users obtain VIA connection settings?

• Set up the VPNCs' VIA web authentication profile to use CPPM as the authentication server; set up a service on CPPM that uses AD as the authentication source.
• Set up the VPNCs' VIA web authentication profile to use an AD domain controller as the LDAP server.
• Set up the VPNCs' VIA connection profile to use two authentication profiles, one RADIUS profile to CPPM and one LDAP profile to AD.
• Set up the VPNCs' VIA connection profile to use one authentication profile, which is set to the AD domain controller's hostname.

Refer to the scenario.# Introduction to the customerYou 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 C

• 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.
• țaa ød
• intca.acnsxtest. com
• 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?
• In rule 1 change Subject-CN to Issuer-CN.
• Move rules 2 and 3 to the top of the list.
• Change the rules evaluation mechanism to first applicable.
• Change the default role to 'mobile-onboarded*

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?

• Use MPSK on the WLAN to which the devices connect.
• Configure WIDS policies that apply extra monitoring to these particular devices.
• Connect these devices to the same WLAN to which 802.1X-capable clients connect, using MAC- Auth fallback.
• Enable dynamic authorization (RFC 3576) in the AAA profile for the devices.
