Question 1

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

Accepted Answer

A

Explanation: The "Fail Strategy" setting within the Aruba Central IDS/IPS configuration dictates the gateway's behavior in the event of an IDS/IPS engine failure. The "Bypass" option configures a fail-open mechanism. This means if the inspection engine fails or is unable to process traffic for any reason, the gateway will permit the traffic to pass through without inspection. This strategy prioritizes network availability and connectivity over security inspection during a failure state, preventing the security feature from causing a network outage.

Question 2

A customer needs you to configure Aruba ClearPass Policy Manager (CPPM) to authenticate domain users on domain computers. Domain users, domain computers, and domain controllers receive certificates from a Windows CA. CPPM should validate these certificates and verify that the users and computers have accounts in Windows AD. The customer requires encryption for all communications between CPPM and the domain controllers. You have imported the root certificate for the Windows CA to the ClearPass CA Trust list.

Which usages should you add to it based on these requirements?

Accepted Answer

B

Explanation: The scenario requires the Certificate Authority (CA) certificate to be trusted for two distinct purposes. First, for validating the certificates presented by domain users and computers during 802.1X authentication, the EAP (Extensible Authentication Protocol) usage is necessary. This allows ClearPass to act as a RADIUS server and validate the client's certificate chain in EAP-TLS or PEAP-EAP-TLS. Second, the requirement for encrypted communication between ClearPass and the domain controllers for account lookups implies the use of LDAPS (LDAP over SSL/TLS). For ClearPass to establish a secure LDAPS session, it must trust the server certificate presented by the domain controller. Enabling the AD/LDAP Server usage for the imported root CA certificate allows ClearPass to validate the domain controller's certificate.

Question 3

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 A. 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. HPE6-A84 practice exam questions HPE6-A84 real exam questions 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. HPE6-A84 actual exam questions # 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

On CPPM, you are creating the authentication method shown in the exhibit below: You will use the method for standalone EAP-TLS and for inner methods in TEAP. What should you do?

Accepted Answer

A

Explanation: The question requires identifying the correct trust usages for the imported Windows CA root certificate in ClearPass. Based on the scenario: 1. EAP Usage: The network must support TEAP with an inner EAP-TLS method for Windows domain computers and users. These clients present certificates issued by the internal Windows CA. For ClearPass to validate these client certificates during the EAP-TLS exchange, the issuing CA's root certificate must be trusted for "EAP" usage. 2. AD/LDAP Server Usage: The scenario explicitly requires that "Communications between ClearPass servers and on-prem AD domain controllers must be encrypted." This is achieved using LDAPS. The domain controllers will present their server certificates (issued by the Windows CA) to ClearPass. To establish a trusted, encrypted connection, ClearPass must validate this server certificate, which requires the "AD/LDAP Server" usage to be enabled for the Windows CA root.

Question 4

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?

Accepted Answer

B

Explanation: Cloud Authentication in Aruba Central assigns roles to clients based on a set of rules. For non-802.1X IoT devices that authenticate using their MAC address, the primary method for dynamic role assignment is device profiling. Aruba Device Insight automatically classifies clients on the network (e.g., as IP cameras, printers, etc.). Administrators can then create "Client Profile Tags" based on these classifications. These tags are used as attributes within the Cloud Authentication policy rules to map a specific type of device to a predefined user role. Therefore, configuring these tags is a necessary prerequisite for creating the role mapping rules.

Question 5

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?

Accepted Answer

C

Explanation: Aruba Central's "Alerts & Events" monitoring dashboard is the most direct and efficient tool for this task. It provides a comprehensive, filterable log of network activities captured by the infrastructure. An administrator can quickly apply filters for the "IoT" client category (or a specific profile like "Raspberry Pi") and the "SSH" application to generate a precise list of all clients that have initiated SSH traffic. This feature is designed for exactly this type of ad-hoc operational visibility and troubleshooting.
