HPE6-A84 Real Exam Questions

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?

A customer has an AOS 10 architecture, which includes Aruba APs. Admins have recently enabled WIDS at the high level. They also enabled alerts and email notifications for several events, as shown in the exhibit. Admins are complaining that they are getting so many emails that they have to ignore them, so they are going to turn off all notifications. What is one step you could recommend trying first?

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 cannot see flow attributes for wireless clients. What should you check?

A company has Aruba gateways and wants to start implementing gateway IDS/IPS. The customer has selected Block for the Fail Strategy. What might you recommend to help minimize unexpected outages caused by using this particular fall strategy?

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 an easy way to communicate the information that an IoT client has used SSH to Aruba ClearPass Policy Manager (CPPM). What step should you take?
