Refer to the scenario. An organization wants the AOS-CX switch to trigger an alert if its RADIUS server (cp.acnsxtest.local) rejects an unusual number of client authentication requests per hour. After some discussions with other Aruba admins, you are still not sure how many rejections are usual or unusual. You expect that the value could be different on each switch. You are helping the developer understand how to develop an NAE script for this use case. You are helping a customer define an NAE script for AOS-CX switches. The script will monitor statistics from a RADIUS server defined on the switch. You want to future proof the script by enabling admins to select a different hostname or IP address for the monitored RADIUS server when they create an agent from the script. What should you recommend?

Refer to the exhibit. Which security issue is possibly indicated by this traffic capture?

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?

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 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?

When would you implement BPDU protection on an AOS-CX switch port versus BPDU filtering?

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?

Question 41

Refer to the exhibit.

Aruba ClearPass Policy Manager (CPPM) is using the settings shown in the exhibit. You reference the tag shown in the exhibit in enforcement policies related to NASes of several types, including Aruba APs, Aruba gateways, and AOS-CX switches.

What should you do to ensure that clients are reclassified and receive the correct treatment based on the tag?

Change the RADIUS action to [Aruba Wireless -Terminate Session] which is supported by all the NASes in question.

Change the RADIUS action to [Aruba Wireless - Bounce Switch Port] which is supported by all the NASes in question.

Enable profiling in each service using one of these enforcement profiles. Set the profiling action to the correct one for the NASes using that service.

Set the Tags Update Action to No Action. Then instead enable the RADIUS CoAs using enforcement profiles in the rules that match clients with the tag shown in the exhibit.

Question 42

You are setting up Aruba ClearPass Policy Manager (CPPM) to enforce EAP-TLS authentication with Active Directory as the authentication source. The company wants to prevent users with disabled accounts from connecting even if those users still have valid certificates.

As the first part of meeting these criteria, what should you do to enable CPPM to determine where accounts are enabled in AD or not?

Add an Endpoint Context Server to the domain controller with actions for querying the domain controller for account status.

Enable OCSP in the EAP-TLS authentication method settings and configure an OCSP override to the domain controller FQDN.

Add a custom attribute for userAccountControl to the filters in the AD authentication source.

Install a Microsoft Active Directory extension in Aruba ClearPass Guest and set up an HTTP authentication source that points to that extension.

Question 43

Refer to the scenario.

This customer is enforcing 802.1X on AOS-CX switches to Aruba ClearPass Policy Manager (CPPM).

The customer wants switches to download role settings from CPPM. The "reception-domain" role must have these settings:

— Assigns clients to VLAN 14 on switch 1, VLAN 24 on switch 2, and so on.

— Filters client traffic as follows:

— Clients are permitted full access to 10.1.5.0/24 and the Internet

— Clients are denied access to 10.1.0.0/16

The switch topology is shown here:

How should you configure the VLAN setting for the reception role?

Assign a consistent name to VLAN 14, 24, or 34 on each access layer switch and reference that name in the enforcement profile VLAN settings.

Configure the enforcement profile as a downloadable role, but specify only the role name and leave the VLAN undefined. Then define a 'reception' role with the correct VLAN setting on each individual access layer switch.

Assign a number-based ID to the access layer switches. Then use this variable in the enforcement profile VLAN settings: %(NAS-ID]4.

Create a separate enforcement profile with a different VLAN ID for each switch. Add all profiles to the profile list in the appropriate enforcement policy rule.

# 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

The customer needs a secure way for users to enroll their new wireless clients in Intune. You are recommending a new WLAN that will provide the users with limited access for the enrollment.

You have set up captive portal for clients on this WLAN to a web page with instructions for enrolling devices. You will need to add several hostnames to the captive portal allowlist manually.

What is one of those hostnames?

The hostname used by ClearPass Policy ManaGer's RADIUS services

The ClearPass Onboard hostname referenced in an Onboard provisioninG profile

The ClearPass Onboard hostname referenced in Intune SCEP profiles

The hostname used by the on-prem domain controllers

Question 49

The customer needs a way for users to enroll new wired clients in Intune. The clients should have limited access that only lets them enroll and receive certificates. You plan to set up these rights in an AOS-CX role named "provision."

The customer's security team dictates that you must limit these clients' Internet access to only the necessary sites. Your switch software supports IPv4 and IPv6 addresses for the rules applied in the "provision" role.

What should you recommend?

Configuring the rules for the "provision" role with IPv6 addresses, which tend to be more stable

Enabling tunneling to the MCs on the "provision" role and then setting up the privileges on the MCs

Configuring the "provision" role as a downloadable user role (DUR) in CPPM

Assigning the "provision" role to a VLAN and then setting up the rules within a Layer 2 access control list (ACL)
