HP HPE6-A84 Exam With Confidence Using Practice Dumps

You need to install a certificate on a standalone Aruba Mobility Controller (MC). The MC will need to use the certificate for the Web UI and for implementing RadSec with Aruba ClearPass Policy Manager. You have been given a certificate with these settings:

Subject: CN=mc41.site94.example.com

No SANs

Issuer: CN=ca41.example.com

EKUs: Server Authentication, Client Authentication

What issue does this certificate have for the purposes for which the certificate is intended?

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

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?

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?
