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.

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.

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”.)

What is a common characteristic of a beacon between a compromised device and a command and control server?

Refer to the exhibit.

You have been given this certificate to install on a ClearPass server for the RADIUS/EAP and RadSec usages.

What is one issue?

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?
