HP HPE6-A84 Practice Test - Questions Answers, Page 5

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?

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?

Which element helps to lay the foundation for solid network security forensics?

Refer to the exhibit.

A customer requires protection against ARP poisoning in VLAN 4. Below are listed all settings for VLAN 4 and the VLAN 4 associated physical interfaces on the AOS-CX access layer switch:

What is one issue with this configuration?

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 relatively easy way to communicate the information that an IoT client has used SSH to Aruba CPPM.

What is one prerequisite?

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 C

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?

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?

Refer to the scenario.

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?
